Weight Gain After Bariatric Surgery - 7 Ways to Stay At Your Low Point
The amount of weight gain after bariatric surgery depends on the procedure chosen and patient behavior.
- Average weight regain ranges from none to 10%, depending on procedure
- Several non-surgical measures exist to prevent or reverse it
- Revision surgery is an option for weight gain after gastric sleeve, gastric bypass, and Lap-Band
Read and click the sections below for everything you need to know about addressing weight gain after weight loss surgery.
Weight Regain by Procedure
Weight Regain by Procedure
Duodenal Switch: Little to none; highest long-term weight loss
Gastric Sleeve, Gastric Bypass, Lap-Band: 8 – 10% regain, but still high long-term weight loss
vBloc Therapy, AspireAssist: None, but only moderate long-term weight loss
Gastric Balloon: 100% regain after balloon removed in 6 months, unless action taken
The procedure you choose will play a large part in determining how much weight you will gain back after you hit your low point.
Following is a list of all widely performed procedures sorted by amount of long-term weight loss and average weight regain.
Highest long-term weight loss and little to no weight regain
- Duodenal switch (70%+ excess weight loss (EWL) after 3 years)
High long-term weight loss, even though 8 to 10% weight regain
- Gastric sleeve (60% EWL after 3 years)
- Gastric bypass (60% EWL after 3 years)
- Lap-Band (55% EWL after 3 years, but highly variable from patient to patient)
Moderate long-term weight loss and no weight regain
- vBloc Therapy (20 – 30% EWL assumed but not confirmed)
- AspireAssist (20 – 30% EWL assumed but not confirmed)
vBloc and AspireAssist each rely on devices to control the patient’s weight. While neither has long-term weight regain research, their nature indicates that patients will reach a weight loss plateau and stay there as long as the devices are used properly.
Moderate short-term weight loss
- Gastric balloon (30% EWL in 6 months, then must be removed)
If the patient does not receive another gastric balloon after their balloon is removed or have one of the more involved procedures listed above, 100% weight regain is likely.
Regardless of which procedure you choose (or chose), the possibility for weight gain after a bariatric procedure will remain present throughout your life.
Remember… bariatric surgery is only a tool. You’ll need to continue doing the right things and making the right choices for the surgery to be effective over the long run.
The key to preventing long term weight regain and reducing your risk of bariatric surgery complications is to learn and address potential pitfalls early on.
Seven behaviors have been proven to reduce the chance of weight gain after bariatric surgery:
Patients with binge eating disorder (BED) tend to lose less weight after surgery. Receiving treatment for BED prior to surgery will lead to less weight gain after bariatric surgery (2).
Your body mass index (BMI) prior to surgery directly relates to how much weight you’ll lose and keep off. For example, one study showed that morbidly obese patients (BMI between 40 and 49.9) had a 15% higher likelihood than super obese patients (BMI of 50 or more) to keep off at least half of their excess weight 10 years after surgery (3).
They will cause weight gain after bariatric surgery and potentially lead to bariatric surgery complications. Your surgeon and bariatric surgery insurance company will both require a psychological evaluation before they approve surgery and the evaluation will include this topic. Be prepared to be honest with your psychologist and work with them to get any problems under control.
This may sound obvious, but you’d be surprised how many patients follow their doctors’ orders for the first year or two and then slowly begin to slip back into their old habits. The best bariatric doctors are not only good in the operating room but are also trained and experienced in helping patients keep the weight off long-term.
If you begin to experience increased food urges, depression or other emotional problems following surgery, talk with your bariatric doctors right away and bring these issues out in the open with your family and support group. Patients who experience these feelings and don’t address them usually gain more weight back.
Patients who continue to monitor their diet with the help of a professional (your surgeon-referred dietitian or nutritionist) have better long-term results (4). Good bariatric doctors partner with or will refer you to a nutritionist or dietitian, so you should not need to find one on your own. The key is to never stop seeing them. For DS patients, diet and exercise works especially well and is very effective towards losing weight after any weight regain.

Revision Surgery Options
Revision Surgery to Reverse Regain
Gastric sleeve, gastric bypass, & Lap-Band revision options
Due to its inherent risks and high price tag, surgery to address weight regain should be your last resort.
If you have not done so already, please review the non-surgical options listed above, especially support groups. If you’re not actively participating in one now, you’ll be pleasantly surprised at how effective they can be.
If you’ve already tried everything else, contact a top surgeon’s office to discuss your options.
See the following pages depending on which procedure you had:
- Have another sleeve procedure, sometimes called a “re-sleeve”
- Convert to a duodenal switch (DS)
- Convert to Lap-Band (“band over sleeve”) or gastric bypass
- Shrink stoma by injecting a sclerosant
- Add an adjustable gastric band (Lap-Band)
- Lengthen the Roux limb of the intestine
- Convert to a duodenal switch
- Rebanding (remove band and add another)
- Convert to a gastric sleeve
- Convert to a gastric bypass
- Convert to a duodenal switch
