Weight Gain After Bariatric Surgery

Hello,
Thank you for your question.
All bariatric surgeries require a diet period. The surgery essentially facilitates the diet for patients; however, they shouldn’t be regarded as a sole means of losing weight. If the patient reverts to their former eating habits, the risk of weight-gain will persist in the long run.
Make sure you follow your dietary plan provided by your nutritionist. 
I hope this answer helps you

Hello,
Thank you for your question. Congratulations on your surgery, I am sorry you are not getting the results you expected. In my experience, patients tend to lose 20-30 pounds in the first month and average 10 a month thereafter, reaching a stable weight at 12-18 months. Factors that influence the rate and total weight loss include gender, age, starting BMI, and extent of lifestyle changes. 
Generally, to be successful, patients need the support of a multidisciplinary team, including their surgeon, a nutritionist, and psychologist. It is essential to maintain the health lifestyle changes expected after surgery. I also caution you to avoid puréed and soft foods and be careful you do not consume too many liquid calories. It is much easier for sleeve patients to consume too many calories through liquids than with solid food. This is because the liquids are digested more quickly than the solids, allowing the patient to more easily "overeat" if consuming high-calorie liquids. Excessive liquid calories can stall and even reverse weight loss. It’s also important not to consume liquids with solids since it can push the food more quickly through your stomach. 
Regular exercise is also essential. At this point the goal is 45 minutes of daily exercise. 
It is also possible there are mechanical issues with your pouch that are leading to your weight gain. In rare cases, revisional surgery may be necessary to maintain weight loss. It is essential you follow up with your surgeon to help you determine the underlying cause of your weight gain; it's important not to feel discouraged during these times and to look to your care team and support network for guidance and encouragement.
Kind regards,
