Bariatric surgery is like other major abdominal surgery. You can best prepare by knowing the benefits and risks of surgery, and by closely following your doctor's instructions.

– Understand the surgical process and what to expect afterward.
– Keep in mind that you’ll never be able to eat the way you did before, and that you’ll have to watch what and how you eat for the rest of your life.
– Talk to people who have had bariatric surgery.
– Write down your reasons for having bariatric surgery and outline your plans to maintain your weight loss after surgery.
– Practice the post-op diet

A majority of patients will regain some weight after a bariatric surgical procedure. The amount regained ranges between a few pounds and all of the weight lost during the operation. The amount of weight regained after the operation is dependent on many factors and this is one of the reasons why so much stress and attention is made to the importance of a healthy lifestyle during the pre-op and post-surgical period.

For laparoscopic gastric bypass, long term weight loss after gastric bypass is suggested to be approximately 60-70% of your excess body weight at 2 years, and 45-50% of your excess

Studies show that bariatric surgery can effectively improve and resolve many weight-related health conditions.

BPD/DS is a combination restrictive and malabsorptive procedure that reduces the size of the stomach by 70%. The pouch is still a bit larger than with other procedures that use restriction. By connecting the pouch to the lower part of the small intestine, absorption of calories and nutrients is greatly reduced.

Patients should have:
– 100 pounds or more of excess weight; or a BMI of 40 or greater

Roux-en-Y (pronounced ROO-en-why) gastric bypass surgery is the most popular bariatric surgery in the United States. In this procedure, the surgeon creates a small stomach pouch and then constructs a “bypass” of some of the small intestine. The smaller stomach pouch restricts the amount of food the patient can comfortably eat, and the bypass decreases the number of nutrients and calories absorbed.
