vBloc Therapy - All You Need to Know

Reviewed by: Frank Chae, MD, CF, FACS

vBloc Therapy

vBloc Therapy is an FDA-approved two-pronged method to help individuals with a BMI between 35 and 45 lose weight and control hunger. First, vBloc Therapy uses an implanted vagal nerve stimulator that blocks hunger signals and reduces how hungry you feel day to day. Second, a network of highly trained surgeons, nurses, and dietitians will use robust tools, technologies, and action plans to get your weight down and keep it down.

This page covers everything you need to determine whether it’s the right weight loss procedure for you…

Weight Loss: Up to One-Third of Your Excess Weight in 12 Months

vBloc Therapy

So, what’s the bottom line? Patients on average lose 22 to 28% of their Excess Weight

Across all vBloc patients, average excess weight loss after 12 months ranges from 22% to 28%. For “moderately obese” patients (BMI 35 – 40), average excess weight loss is around 33%.

As with any weight loss surgery procedure, the amount of weight you will lose depends on:

  • The surgical team that you choose and how comprehensive their pre- and post-surgery education support is
  • How strictly you adhere to the pre- and post-surgery diet, exercise, and behavior regimen prescribed by your surgeon’s team
  • Your body and how well it responds to your chosen procedure

Health Benefits: Diabetes, Cardiac Improvements

vBloc Therapy

vBloc patients, in one small study 17 of 28 patients, saw measurable improvements in hypertension and type 2 diabetes (6). For Type 2 diabetics, after 12 months, 85% of patients were able to maintain, reduce, or discontinue their current level of diabetes medications. The same study confirmed that health gains from initial weight loss are largely sustained at 24 months.

In a larger study of 147 participants (7), patients experienced significant improvements in several obesity related risk factors including:

  • -9 mmHg reduction in Systolic blood pressure
  • -6 mmHg drop in their Diastolic blood pressure
  • -15 mg/dL drop in Cholestrol
  • -41 mg/dL in Triglyceride
  • -5% drop in HbA1c
  • 7 inch reduction in waist circumference

General (non-vBloc-specific) weight loss research has also identified significant improvement in cardiovascular disease and diabetes with modest weight loss.

For example, one study (8) of over 5,000 people with type 2 diabetes found that those who lost 5 to 10% of their body weight had:

  • Increased odds of achieving a 0.5% point reduction in HbA1c
  • 5-mmHg decrease in diastolic blood pressure
  • 5-mmHg decrease in systolic blood pressure
  • 5 mg/dL increase in HDL cholesterol
  • 40 mg/dL decrease in triglycerides

All of these results are very good news for people with type 2 diabetes.

Additionally, that same study found that improvements in most risk factors improved even further for patients who lost 10 to 15% of their body weight.

Qualify: 35+ BMI with Health Issues, 40 – 45 Without

To qualify for any bariatric surgery you will have to meet certain qualifications. vBloc is no different. Ask your doctor to confirm that you meet all the following before you can qualify for vBloc Therapy:

  • Age: 18+
  • Body Mass Index (BMI): must be 35 to 45:
    • 35 to 39.9 must have an obesity-related health problem such as, but not limited to:
      • High blood pressure
      • High cholesterol
      • Type 2 diabetes
      • Sleep apnea
    • 40 to 45, no health problems required to qualify
  • You have been unable to keep off weight with diet or exercise during a medically supervised diet program in the last 5 years

If you meet the above requirements, click here to contact a vBloc patient representative to find a surgeon and discuss your next steps.

vBloc Therapy may not be right if any of the following apply to you:

  • Pregnancy: your surgeon may deactivate (and later reactivate) your device if you become pregnant
  • Contraindications that will disqualify you:
    • Cirrhosis or high blood pressure in the veins of the liver
    • High blood pressure in the veins of the liver (portal hypertension)
    • Enlarged veins in the esophagus
    • A significant hiatal hernia of the stomach
    • Already have an implanted electronic medical device, such as a pacemaker
    • Plan to have an MRI or diathermy procedure using heat
    • Patients at high risk for surgical complications

Cost
$18,500 Average, Financing Available

Cost: $18,500 Average, Financing Available

vBloc Therapy

vBloc Therapy costs about the same as other types of weight loss surgery.

The total average cost is about $18,500 total (range from $17,500 – $19,500), which includes:

  • Pre-Op Costs
  • Surgery Costs, including the device
  • Post-Op Costs, including ongoing support from the vBloc Achieve one-on-one and group coaching program)

Note that most other procedures do not include Post-Op costs in their quoted fees, such as follow-up doctor visits or device adjustments.

Financing Options for vBloc Therapy

  • Secured Medical Loans
    • A secured medical loan is a type of loan from a bank or credit union that you must back with some sort of collateral (a home being the most common form of collateral)
  • Unsecured Medical Loans
    • Unsecured medical loans allow you to borrow money without putting up collateral (see secured medical loans above). But, the tradeoff is you will pay a higher interest rate on the loan, making unsecured loans ultimately more “expensive” than a secured loan over the long run.
  • Payment Plan Through Surgeon
    • Most surgeons offer some kind of payment plan to help you make treatment more affordable. Definitely add this to your list of questions when interviewing surgeons
  • Friends & Family
    • The option of asking your friends and family to help you finance your surgery will obviously vary substantially from person to person. If thinking about this, the best thing you can do is look at the decision from as many angles as you can, and then make the best decision you know how.
  • Retirement Plan Loans
    • This may be an option for you, depending on what your retirement plan allows for. Contact your HR department or retirement planner and ask if your retirement plan allows for hardship withdrawals. But, make sure to crunch all the numbers before you do this. It’s very possible using retirement savings to invest in your health will make financial sense in the long term, but be 100% sure you’re comfortable with this trade off before spending your hard earned retirement savings.
  • Permanent Life Insurance Loans
    • A form of life insurance called “permanent” life insurance offers you benefits while you’re still alive, as opposed to paying out only after you are deceased like basic life insurance. This can be challenging to set up, and can take a significant time to accumulate value, so ask a financial planner, insurance broker, or life insurance representative for guidance before going forward.

These options can be understandably overwhelming. If you want to speak with a professional who can answer any questions for your specific circumstances…

vBloc Therapy

While parts of your total cost may be covered, vBloc Therapy is not specifically included in most insurance plans. According to Enteromedics, the makers of vBloc Therapy, work is being done to get vBloc added to insurance plans across the country.

However, vBloc may be able to help you get some (or all) of your procedure costs paid for in certain circumstances.

vBloc Patient Representatives will help you determine whether your insurance will cover any part of your surgery. They will also help you apply for insurance coverage and appeal denials, if necessary.

Procedure
Hunger-Controlling Device Implanted, Laparoscopic

Procedure: Hunger-Controlling Device Implanted, Laparoscopic

vBloc Therapy

vBloc Therapy, pioneered by Enteromedics, combines the hunger-controlling effects of the implanted vBloc Therapy device (formerly called the Maestro Rechargeable System) with a robust weight loss support program, called vBloc Achieve, to help improve patients’ long-term success rates.

The vBloc Therapy device, which functions much like a pacemaker, and can be removed or deactivated if needed, was approved by the FDA in 2015. The system uses controlled electrical stimulation to block hunger signals sent from your stomach to your brain. In other words, it works by tricking your brain into thinking your body has a lower “set point.”

What is My Set Point?

Definition: Set Point

Your body has a natural tendency to maintain a specific weight (its “set point”) and will adjust internal body processes accordingly. If your weight goes above or below its set-point range, your body will get you back in line by:

  1. Speeding up or slowing down metabolism
  2. Increasing or decreasing hunger impulses

Many people’s set point range puts them in the “obese” category because evolution has built the body to survive times of famine by storing excess fat. To learn more, see our Set Point Theory page.

The support program includes:

  • Registered Dietitian to track your weight loss, make diet and exercise recommendations, provide emotional support, and motivate you to stay on track
  • Technology to help you and your Registered Dietitian track your results, including an Ambio Scale to track and upload your weight loss to the internet

How It’s Performed

During the procedure, your surgeon will implant the vBloc Therapy device below your rib cage just under the skin. Your surgeon will then attach the device to your vagal nerve, just above the stomach, via two leads (wires). The whole procedure usually takes between 60 and 90 minutes.

Once in place, the device will block the vagal nerve from delivering hunger signals to the brain, making you feel full between meals and full sooner after smaller meals.

vBoc Device Materials

The vBloc Therapy Device is made of…

  • Surgical metals
  • Medical grade silicone
  • Rechargeable lithium battery

About the Device

The vBloc device is actually a series of several different components that combine to make your vBloc therapy device fully functional and effective:

  • Neuroregulator: this is the main part of the device that will be implanted just below your skin. It is used to control the “leads” (see below) to your vagus nerve, as well as help charge the device.
  • Lead System: These are the “wires” that will connect from the neuroregulator to your vagus nerve. They will deliver the electrical signals to make you feel less hungry.
  • Mobile Charger: This is the device outside your skin that will be used to charge your neuroregulator.
  • Transmit Coil: The transmit coil uses radio frequencies to connect the neuroregulator to either the mobile charger to charge your device or connect to the clinician programmer (see below) to make changes to your device.
  • Clinician Programmer: Using the transmit coil your doctor will connect to your neuroregulator to make adjustments to your device settings, as well as download information from the device about how both you and your system are doing.

Recharging the Device

The device is battery-powered so it is important you charge it at least every other day. To recharge the device, you should:

  1. Connect the Mobile Charger to the AC Recharger and then plug the whole unit into the wall.
  2. Once the Mobile Charger is fully charged, remove it from the AC Recharger and connect it to the Transmit Coil.
  3. Position the Transmit Coil on the skin over the Neuroregulator. The charge in the Mobile Charger is then transferred to the Neurorgulator through the Transmit Coil.
  4. Secure the Transmit Coil in place with the velcro belt. Allow the device to charge for 20 to 30 minutes (may take a few hours to fully recharge, if charging is not done every two days; if the device goes two month without recharging, you may need to visit your doctor to restart it)

During charging, you can be mobile and monitor the process on the display of the Mobile Charger.

Recovery
Back to Work in 3 – 4 Days

Recovery: Back to Work in 3 – 4 Days

Recovery for this procedure is usually quick, especially compared to traditional surgeries. Your procedure will likely be performed in an outpatient setting, so you should be going home that day.

Once home, it will probably take you a few weeks of rest to fully recover, but you should be back to work in 3 or 4 days.

Diet & Life After
Develop Plan with Nurse or Dietitian

vBloc Therapy

Because vBloc does not change your anatomy, there are no specific dietary restrictions or a risk of malabsorption (so no need for vitamin supplementation). But, your vBloc device is designed to work in tandem with lifestyle changes. So, as part of your vBloc Therapy, your nurse or dietitian will work with you to find ways to improve your diet and exercise habits.

The recommended lifestyle changes include three main components:

  • One-on-One Coaching: You have the opportunity to meet remotely with an expert dietician who will help you personalize your meals and exercise routine. For example, your coach can provide you with sample menus to help you plan more nutritious and fulfilling meals.
  • Personal Tracking Technology: Using the help of an electronic, wireless scale, your data can safely be shared with your dietician to give you personalized, and even real time, feedback about your weight loss.
  • Online Tools and Resources: vBloc Achieve provides patients with several online resources, including:
    • Meal and exercise tracking
    • Step-by-Step Guides for your full vBloc experience
    • Weight loss education materials
    • Helpful videos to help you learn the best

These changes to your day-to-day meals and exercise routine are not required (in the sense that you will face medical complications if not followed). However they are highly recommended to ensure you successfully lose weight and, most importantly, keep it off.

Removal
Reversible Procedure, Replacement Required After 5+ Years

Removal: Reversible Procedure, Replacement Required After 5+ Years

vBloc Therapy is one of three reversible mainstream weight loss surgery procedures, alongside Lap-Band surgery and the gastric balloon. However, it is the only reversible procedure that can be activated (start therapy) and deactivated (stop therapy) wirelessly. The vBloc device can be removed or replaced as needed.

The vast majority of vBloc patients (14 out of 15) do not require revision surgery. For those who do, most have relatively minor procedures to reposition or reconnect the device rather than complete removal or replacement (9).

The vBloc Therapy device is warranted to last 5 years with normal use and recharging but may last as long as 8 years before revision surgery is needed to replace the battery.

The device can be deactivated by your doctor at any time for an emergency or pregnancy.

Downsides
Risk of Complications & Side Effects

Downsides: Risk of Complications & Side Effects

Non-Severe Complications & Side Effects

Non-Severe Complications & Side Effects

The most commonly reported non-severe problems associated with vBloc Therapy include:

  • Abdominal Pain or Cramping
  • Belching
  • Difficulty swallowing (dysphagia)
  • Heartburn
  • Indigestion (dyspepsia)
  • Nausea
  • Surgical Pain

Most of these issues were mild to moderate in severity and are not permanent and resolve on their own (10).

Serious Complications & Side Effects

Serious Complications & Side Effects

At 3.7%, the rate of Serious Adverse Events (SAE) for vBloc Therapy is lower than all other implanted devices for weight loss (11) and is lower than the serious complication rate of more invasive bariatric surgery procedures like gastric sleeve, gastric bypass, and lap band surgery.

Documented vBloc Therapy SAE’s include:

  • Vomiting (less than 1% of patients)
  • Neuroregulator malfunction
  • Pain at the neuroregulator site
  • Collapsed lung
  • Gallbladder disease

Additional risks to consider:

  • The long-term effects of vBloc Therapy have not been studied
  • The rate of patients requiring vBloc revision surgery to reposition, replace, or remove the device is about 1 in 15 patients after 18 months (6.8%) (12)

Pregnancy

Pregnancy

vBloc Therapy does not affect your ability to get pregnant because it does not alter your anatomy. However, you cannot have this procedure if you are currently pregnant, and you will need to have the device deactivated immediately if you become pregnant. The device can be deactivated (stop therapy) and reactivated (start therapy) wirelessly by your surgeon at any time.

Interference with Other Devices

Interference with Other Devices

The vBloc Therapy device can interfere with other devices such as:

  • Airport security screening devices – your device will likely set off metal detectors and may be seen through airport screening technology. You should not experience any delays as long as you present your vBloc ID card.
  • MRI machines – it is not safe to have an MRI with the vBloc device in place as it can result in pain, heating, burns, or nerve damage. Contact your doctor to discuss before having an MRI.
  • Pacemakers – patients with a pacemaker cannot have vBloc Therapy because the devices can interfere with each other.
  • Defibrillators – likewise, patients with defibrillators cannot have vBloc Therapy.

Vs. Other Types of Surgery
Safer, Less Weight Loss, Fewer Diet Changes & Side Effects

Vs. Other Types of Surgery: Safer, Less Weight Loss, Fewer Diet Changes & Side Effects

Generally speaking, the other more invasive weight loss procedures result in more weight loss and therefore a higher degree of health improvement than vBloc Therapy.

However, vBloc Therapy has the lowest rate of complications, does not require significant diet changes, and has fewer and less severe side effects than most other widely accepted procedures.

Total costs of vBloc are comparable to other types of surgery, although vBloc (along with Gastric Balloon) is less likely to be covered by insurance.

Your Results

What is your gender?

Are you pregnant, or do you plan to be over the next two years?

Input your Height and Weight

Do you have any weight-related health issues (diabetes, asthma, hypertension, sleep apnea, joint problems, etc.)?

How do you feel about regular visits with a bariatric professional (doctor, dietician, etc.)?

Would the risk of uncomfortable side effects like nausea, vomiting, or diarrhea be a good motivator for you to maintain the right diet, or would you rather avoid those side effects at all costs?

Do you have insurance that covers bariatric surgery?

Are you on anticoagulation medication (blood thinners)?

Are you comfortable with the idea of an external device being left inside your body after surgery?

Are you willing to be on a serious regimen of vitamins and supplements for the rest of your life?

Unfortunately, none of the available types of weight loss surgery seem to be a good fit.

Here's why: Earlier you said that you have not thoroughly explored other treatments for obesity. That is required for all procedures except gastric balloon. Your body mass index ("BMI", which is based on your height and weight) is over 40, and gastric balloon is only available for BMI's between 30 and 40. So unfortunately, none of the available procedures seem to be a good fit.

Unfortunately, none of the available types of weight loss surgery seem to be a good fit for you.

Body Mass Index & Health Conditions

Your body mass index is XX.

In order to qualify for gastric sleeve, gastric bypass, duodenal switch, Lap-Band surgery, your body mass index (BMI) must be 40+ or between 35 and 40 only if you also have weight-related health issues.

For vBloc Therapy, your body mass index (BMI) must be 40+ or between 35 and 45 only if you also have weight-related health issues.

Gastric balloon requires a BMI between 30 and 40 (with or without health issues).

Even though your BMI would qualify you for the gastric balloon, you said anything less than 50% excess weight loss is unacceptable. Unfortuantely, gastric balloon only results in about 20% excess weight loss.

Since you are or are planning to be pregnant, you should not have weight loss surgery at this time.

Most women should wait least one year to 18 months after bariatric surgery before getting pregnant. This is the timeframe when many patients experience the biggest amount of weight loss, and it is the most difficult period for keeping your body’s nutritional needs in line.

Many bariatric surgery procedures prevent patients from getting the vitamins their bodies need from the foods they eat. So even after you’ve waited the 12 to 18 months, you’ll need to make sure you stay on top of your bariatric vitamins both before and during your pregnancy.

Winner:

Gastric sleeve surgery, also called “vertical sleeve gastrectomy”, drastically reduces the size of the stomach which causes patients to feel full sooner and lowers the production of hunger-inducing hormones, leading to significant long-term weight loss and health improvement.

Gastric bypass surgery, also called “ Roux-en-Y gastric bypass”, makes the stomach smaller and reroutes the intestines, causing patients to feel full sooner and absorb less food, resulting in significant long-term weight loss and health improvement.

The endoscopic intragastric balloon, or “gastric balloon,” is a relatively new, non-invasive, and temporary procedure whereby a durable silicone balloon is passed through the mouth, down into the stomach, and filled with saline to make patients feel full sooner, leading to significant short-term weight loss.

It was developed to "bridge the gap" between pure diet and exercise and a more complicated bariatric procedure like gastric sleeve surgery.

The Biliopancreatic Diversion with Duodenal Switch (BPD-DS), or “Duodenal Switch” (DS) for short, deserves more credit and attention than it’s been given. On average, it results in more weight loss than any other procedure.

Its mortality risks are on par with other procedures, and it may be the best procedure for those with a 50+ body mass index (“super-obese”) in terms of average weight loss and elimination of obesity health problems.

However, its higher rate of serious complications and the amount of malabsorption that it causes command careful consideration before moving forward.

Gastric banding, also called Lap-Band surgery, is quickly losing popularity due to the high number of patients requiring band removal over the long-term. However, the procedure still has a lot going for it such as being adjustable and reversible.

vBloc Therapy is an FDA-approved two-pronged method to help individuals with a BMI between 35 and 45 lose weight and control hunger.

First, vBloc Therapy uses an implanted vagal nerve stimulator that blocks hunger signals and reduces how hungry you feel day to day.

Second, a network of highly trained surgeons, nurses, and dietitians will use robust tools, technologies, and action plans to get your weight down and get it at your new low.

Weight Loss

The more "involved" procedures like gastric sleeve, gastric bypass, duodenal switch, Lap-Band aggressively restrict the amount of food your stomach can hold ("restrictive") and/or alter your digestive system to reduce the amount of food your body can absorb ("malabsorptive"). As a result, they are much more likely to lead to weight loss that exceeds 50% of your excess weight.

The less involved restrictive procedures like gastric balloon and vBloc Therapy typically result in a more moderate amount of weight loss.

You said anything less than 50% excess weight loss is unacceptable, so your best options may be the more "involved" procedures like gastric sleeve, gastric bypass, duodenal switch, or Lap-Band.

You said you are only interested in less involved procedures, so gastric sleeve, gastric bypass, duodenal switch, and Lap-Band are probably not for you. Less involved procedures, including Gastric Balloon or vBloc Therapy, may be more appropriate.

Failed Diet Programs

Most types of weight loss surgery - gastric sleeve, gastric bypass, duodenal switch, Lap-Band, and vBloc Therapy - are only appropriate for people who have tried and failed with a medically supervised diet program.

Gastric balloon surgery is the only procedure that does not require this.

Talk with your surgeon about how to get started with a supervised diet program.

Talk with your surgeon about how to get started with a supervised diet program.

Health Improvement

You indicated that you currently have weight-related health issues, which will likely improve and may even be "cured" following weight loss surgery. Generally speaking, the more weight you lose, the more health improvement you are likely to experience. Following is the average excess weight loss by procedure, from highest to lowest:

  1. Duodenal switch (65% - 90%)
  2. Gastric Sleeve & Gastric Bypass (tie at 65% - 75%)
  3. Lap-Band (45% - 70%)
  4. vBloc Therapy (20 - 25%)
  5. Gastric Balloon (~20%, but removed after 6 months)

However, weight loss and health improvement are not the whole story, and several other factors have been taken into account in our recommendations.

Body Mass Index & Health Conditions

Your body mass index is XX.

In order to qualify for gastric sleeve, gastric bypass, duodenal switch, Lap-Band surgery, your body mass index (BMI) must be 40+ or between 35 and 40 only if you also have weight-related health issues.

For vBloc Therapy, your body mass index (BMI) must be 40+ or between 35 and 45 only if you also have weight-related health issues.

Gastric balloon requires a BMI between 30 and 40 (with or without health issues).

Patients Under 18

While bariatric surgery is performed on patients under 18 years of age, your surgeon will have several concerns including: whether you are disciplined enough to adhere to strict diet and exercise requirements (many teens are not ready for or cannot prepare for that level of dedication), whether your family and friends will be supportive enough, whether you can properly evaluate the risks vs the rewards of surgery, whether the procedure could potentially affect your growth or bone density (especially malaborptive procedures), and the unknowns about the long-term effect of having an external device in your body (for those procedures that include one like Lap-Band or vBloc). The gastric balloon is not an option as it is currently only allowed for patients over 18.

Patients 65 or Older

Since you are 65 or older, it is possible that bariatric surgery is a good option, but you may be less likely to qualify than younger patients due to higher risks.

For example, one study evaluated 100 patients over the age of 65 and found that bariatric surgery for seniors has similar benefits and no additional risks compared to patients under 65. Their results showed that morbidly obese patients over 65 have shorter hospital stays following bariatric surgery than younger patients. The same study showed that after two years older patients lost almost 76% of their excess weight.

However, a much larger aggregate study of over 25,000 patients showed that seniors experience less weight loss and more complications than younger patients and concluded that, "Limiting bariatric surgical procedures to those younger than 65 years is warranted because of the high morbidity and mortality associated with these operations in older patients."

Ongoing Doctor Visits

After the initial surgery, Lap-Band and vBloc Therapy may require several doctor visits to "fine tune" the device to the point that it is just right for you. The other procedures tend to require less long-term follow up doctor visits, including gastric sleeve, gastric bypass, gastric balloon, and duodenal switch. You indicated that seeing your doctor regularly is not an issue for you, so this is just for your information.

Ongoing Doctor Visits

Since avoiding the doctor is important to you, you may want to stick with procedures that tend to require less frequent follow up, including gastric sleeve, gastric bypass, gastric balloon, or duodenal switch. After the initial surgery, certain procedures like Lap-Band and vBloc Therapy may require several doctor visits to "fine tune" the device to the point that it is just right for you.

Food Cravings

There are several reasons people crave food, including food addiction, an overproduction of hunger-causing hormones, and hunger impulses sent from the stomach to the brain. Since food cravings are a big issue for you now, they are likely to continue after surgery unless you choose a procedure that specifically addresses them.

Although weight loss after vBloc Therapy is not as great as many of the other procedures, it is specifically designed to block hunger impulses sent to the brain. Gastric sleeve has impressive weight loss and reduces food cravings by completely removing a large portion of your hormone-secreting stomach.

Dumping Syndrome

For some patients, eating foods high in fat, carbohydrates, or sugar, eating foods that are too hot or too cold, or drinking liquids during meals can result in dumping syndrome. Symptoms include bloating, diarrhea, dizziness, heart palpitations, nausea, rapid heart rate, sweating, and vomiting.

While very uncomfortable if it happens, this can actually be a good thing as it provides a very strong deterrent against "cheating" on your new bariatric diet which can lead to better long-term weight loss.

Dumping syndrome is experienced by about 4 out of every 5 gastric bypass patients. The other procedures are much less likely to cause this issue.

Since you indicated that you're open to your body reacting negatively to the wrong diet choices, you may want to keep gastric bypass on your list of possible procedures.

Since you indicated that you don't want to worry about the symptoms associated with dumping syndrome, you may want to remove gastric bypass from your list of procedures to consider.

Insurance

The fact that your insurance covers weight loss surgery is great news, although some individual procedures may not be covered. Even after a new procedure has been proven in the scientific community, it often takes years for insurance companies to add it to their list

Your policy will probably cover gastric sleeve, gastric bypass, Lap-Band, and duodenal switch since they have all been around for a long time.

Gastric balloon and vBloc Therapy will probably not be covered directly, but your surgeon's office may be able to help you get some of the costs covered. However, these procedures may be covered on a case-by-case basis.

Anticoagulation Medicine

Since you are currently taking anticoagulation medication (blood thinners), you will have a higher risk of marginal ulcers forming in the new stomach pouch created during a gastric bypass procedure. As a result, if you are on the fence between gastric bypass and a different procedure, you may want to choose the other procedure.

As a result, if you are on the fence between gastric bypass and a different procedure, you may want to choose the other procedure.

Implanted Device

Gastric balloon, vBloc Therapy, and Lap-Band each include a different types of device that is left inside the body. Gastric sleeve, gastric bypass, and duodenal switch do not.

Since you're open to that idea, we haven't given this any weight in our recommendation - we just wanted you to be aware.

Since you are uncomfortable with the thought of a device being left inside your body, you may want to avoid gastric balloon, vBloc, and Lap-Band.

Reversible Procedures

Generally speaking, the reversible procedures, including vBloc Therapy, Lap-Band, and gastric balloon, do not result in as much weight loss or as much health improvement as the "permanent" gastric sleeve, gastric bypass, and duodenal switch procedures.

However, they do have a few points in their favor:

  1. Weight loss can still be significant, especially depending on your goals
  2. They allow you to "stick your toe in the weight loss surgery waters" without taking the full leap, especially when diet and exercise aren't working
  3. The risk of serious complications tends to be lower
  4. They can serve as a "bridge" (first step) to a permanent procedure. The more weight you lose before a permanent procedure, the lower the risk of complications and the more long-term weight loss you are likely to achieve.

Since the ability to reverse your procedure is important to you, you should move vBloc Therapy, gastric balloon, and Lap-Band surgery higher up your list.

Since the ability to reverse your procedure is not important to you, you may want to focus more on other procedure differences like potential weight loss, health improvement, and risks.

Vitamins & Supplements

All weight loss procedures require some level of supplementation, although some are more serious with their requirements than others. The two malabsorptive procedures, gastric bypass and duodenal switch, alter the path of your digestion to prevent your body from absorbing as much food. While this tends to lead to greater weight loss, it also carries with it a higher risk of malnutrition. As a result, you will be on a more robust and stricter vitamin and supplement regimen than with the other procedures.

Since you indicated that you are not willing to be on a serious regimen of vitamins and supplements for the rest of your life, you should think hard about whether weight loss surgery is right for you.

The only procedure that does not require permanent long-term supplementation is gastric balloon because the balloon is usually removed after 6 months.

The "restrictive" procedures tend to lead to much lower instances of vitamin deficiency, but you still may need to be on a more moderate regimen of vitamins since your body will not be able to hold (and therefore absorb nutrients from) as much food.

The malabsorptive procedures require strict, lifelong supplementation, so you should probably avoid those procedures.

10 Steps to Long-Term Weight Loss with vBloc Therapy

Start to Finish: 10 Steps to Long-Term Weight Loss with vBloc Therapy

Step 1: Contact vBloc

Contact vBloc to be partnered with a patient representative who will answer all your questions, help you determine whether vBloc is a good option for you and, if it is, connect you with a qualified surgeon.

Step 2: Apply for Insurance or Financing

If needed, you will be assigned a vBloc Access case manager to help you apply for insurance coverage and, if necessary, appeal any denials. Your patient representative can also help point you in the right direction for competitive financing options.

Step 3: Meet with Your Surgeon

You will meet with your surgeon to discuss your surgery and vBloc Therapy, set expectations, and work through the necessary pre-surgery steps.

Step 4: Have Surgery

The day of your surgery, your bariatric surgeon will implant the vBloc Therapy device just under the skin and connect two leads to the vagal nerve just above the stomach. Since the procedure is done laparoscopically, there should be minimal scarring. It is done under general anesthesia, usually takes 60 to 90 minutes, and this is usually done on an outpatient basis. This means you will probably be in and out of the hospital on the same day..

Step 5: Return to Regular Life

Most patients are back to work and regular daily activity after a few days. As with any surgery, full recovery may take several weeks.

Step 6: Charge Your Device

You will recharge your device for 20 to 30 minutes every one to two days by placing the charger on the outside of your skin just above the device and holding it in place with a strap.

Step 7: Effects of the Device

The device is programmed to deliver hunger-preventing vagal nerve stimulation at least 12 hours per day while you are awake. It is designed to help you feel full sooner and longer after eating small portions. Some patients describe a feeling of fullness in the stomach while other do not report this effect.

Step 8: Diet Changes Highly Recommended But Not Required

Following recovery, there are no dietary restrictions as as result of the device, and there is no risk of malabsorption (so no need for vitamin supplementation), although your nurse or dietitian will work with you through the “vBloc Achieve” program to improve diet and exercise habits for better results.

Step 9: Ongoing doctor visits

Each patient is different, so to ensure the proper amount of therapy, the settings of your vagal nerve stimulator may need to be adjusted during follow up office visits with your surgeon. Settings are adjusted wirelessly (no additional surgery required). An initial visit will be required about two weeks after surgery. The frequency of subsequent follow up visits will vary by patient.

Step 10: Establish Long-Term Habits

You will continue to work with your vBloc Therapy team, through the vBloc Achieve program, who will help you stay on track with diet, exercise, and education.

For example, your team will work with you to set specific goals and create a plan to help you achieve them. They will discuss special tools with you that will give them more information that will help you succeed, such as an internet-connected scale and activity tracking device for automatically sending weight loss progress and exercise information. While ongoing check-ups with your surgeon will be in-person, meetings with your vBloc counselor are conducted virtually over the phone or internet.

  • 5+ Year Battery Life

    The battery is warranted to last 5 years but is designed to last up to 8. Outpatient surgery will be required to replace the battery.

A few more things to note about vBloc Therapy:

  • The device can be deactivated without surgery if needed (like you become pregnant, for example)
  • It can be removed entirely for any reason, such as conversion to a more aggressive weight loss surgery
