Weight Gain After Bariatric Surgery & How to Avoid or Reverse It
Are you likely to experience weight gain after bariatric surgery? It depends on factors both in and out of your control.
- How much do patients gain back on average?
- 7 ways to minimize weight regain after bariatric surgery
- Surgical options to reverse weight gain after weight loss surgery
- Patient experiences (please share your own as well!)
The procedure you choose will play a large part in determining how much weight you will gain back after you hit your low point.
Patients who undergo primarily restrictive procedures (i.e. procedures that are not calorie malabsorptive, including gastric bypass surgery, mini gastric bypass surgery, gastric sleeve surgery and lap band surgery) usually gain around 8 to 10% of their weight back.
Malabsorptive procedures such as duodenal switch surgery have been shown to result in greater maintained excess weight loss over the long-term. After any weight regain, patients who undergo malabsorptive procedures experience at least 10% to 15% greater excess weight loss than restrictive procedures.
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 baratric 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:
- Stop binge eating well before 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.1
- Lose as much weight as possible prior to surgery - 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 liklihood than super obese patients (BMI of 50 or more) to keep off at least half of their excess weight 10 years after surgery.2
- Address alcohol and drug abuse problems as 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.
- Follow your bariatric doctors’ advice to the letter – 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.
- Join and participate in a good weight loss surgery support group – weight loss surgery patients who actively participate in support groups have roughly a 10% lower body mass index than patients who do not.3
- Address food urges and lack of well being if you start to experience them after surgery - 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.
- Continue to
get nutritional counseling – 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.
Review the following pages for more about proper diet and eating habits…
- Bariatric Diet - learn the proper diet before and after surgery and tips to stay on track
- Bariatric eating – how you eat vs what you eat
In addition to the above, the following pages will set you up for success, both reducing your risk of complications and minimizing your weight gain after bariatric surgery…
- Bariatric Doctors – how to find, interview and choose the best surgeon
- Life After Weight Loss Surgery – what to expect in every area of your life
- Exercise for Bariatric Surgery Patients
- In-person weight loss surgery support groups and online weight loss support – finding and participating in the right support groups has been proven to lead to better weight loss
The first path your doctor will have you take to reverse weight gain after bariatric surgery is good old-fashioned diet and exercise.
If these are not effective towards keeping the weight off after surgery, it may be because your new stomach (and possibly the digestive openings made during surgery) has stretched which allows you to eat more before feeling full.
