Weight Loss Procedures

Laparoscopic Roux-en-Y Gastric Bypass (RYGB) surgery is a procedure that uses both restriction and malabsorption to achieve weight loss. With Roux-en-Y gastric bypass surgery, staples are used to permanently close off part of the stomach and create a small stomach pouch for the food you eat. A Y-shaped piece taken from an upper portion of the small intestine is then attached to this small stomach pouch. As a result, food from your stomach pouch bypasses the initial portion of the intestine, which normally would absorb calories and nutrients after eating.This is the most common types of weight-loss surgery performed in the United States.

Laparoscopic Sleeve Gastrectomy is a restrictive bariatric surgery. During this procedure, the surgeon creates a small, sleeve-shaped stomach by removing approximately 85 percent of the stomach. The remaining stomach is about the size of a banana. Weight loss occurs because the procedure causes the stomach to tolerate a limited amount of food, causing a feeling of fullness more quickly.

Laparoscopic Adjustable Gastric Banding is a restrictive procedure in which a silicone band is placed around the upper part of the stomach, creating a much smaller stomach pouch. The band slows the passage of food from the stomach into the intestine, which allows you to feel full for a much longer time after eating.

  • Diabetes remission (blood sugars at normal levels and all diabetes medications eliminated) in 79 percent of patients
  • Improvement in sleep apnea in 75 percent of patients
  • Average cost of diabetic and hypertension medications dropped from $237 a month to $43 a month
