In general, after any weight loss procedure, patients who continue to monitor their postoperative diet, maintain good eating habits and get regular exercise are more likely to maintain their weight loss.

Surgery, healthy eating habits and exercise will help decrease the BMI with resolution or significant improvement of the medical problems associated with the weight.

Complications can be minimized by following standardized protocols and implementing a team approach by staff that is well trained in this field.

As with any surgical intervention, complications can occur.  We focus on early detection of complications to manage at an early stage. Please feel free to contact the surgeon or the staff after surgery if you are experiencing any unusual symptom.

SPECIAL NOTE TO WOMEN OF CHILDBEARING AGE:  Pregnancy should be avoided if possible in the first 2 years after surgery.
