Q. What are the risks in a gastric bypass surgery for weight loss? I am obese and I am interested in doing this surgery, but I’m scared. What are the risks of this surgery?

A. The resulting weight loss in gastric bypass surgery is typically dramatic, and markedly reduces co-morbidities of obesity. However, complications are common and surgery-related death occurs within one month in 2% of patients. As in any type of abdominal surgery there is the risk of developing an infection and sepsis, venous thrombosis, hemorrhage, hernia, bowel obstruction and leak from the gut. This particular surgery puts the patient in danger also for mineral and nutritional losses.

Q. What types of gastric bypass surgeries are there? I heard all sorts of options for gastric bypass are available. What is the most in use?

A. Bariatric surgeries or – gastric bypass surgeries for weight loss fall into three categories: Restrictive procedures make the stomach smaller to limit the amount of food intake, malabsorptive techniques reduce the amount of intestine that comes in contact with food so that the body absorbs fewer calories, and combination operations employ both restriction and malabsorption. The exact one to be done should be decided with the physician according to each patients abilities and pre-operative function level.
