Surgical Weight Loss Options
At Central DuPage Hospital's (CDH) Bariatric Treatment Center, patients are able to lose a substantial amount of weight and keep it off over time with the help of weight loss surgery. Routinely, health conditions associated with clinically severe obesity are significantly improved or completely resolved after weight loss surgery resulting in a more healthy, better quality life.
CDH offers two surgical treatment options: Roux-en-Y Gastric Bypass and Lap-Band® (adjustable band) laparoscopic procedures.
The Roux-en-Y Gastric Bypass
This procedure minimizes the amount of food going into the stomach, as well as the amount of food absorbed in the digestive system. This is achieved by separating the stomach into a small and a large section. Food goes into the smaller stomach section first resulting a full sensation with less food. Food then passes through a shortened section of the small intestine, allowing less food to be absorbed and used by the body. This procedure can be performed laparoscopically or through an open incision.
Patients undergoing laparoscopic or open Roux-en-Y gastric bypass surgery achieve an average weight loss of 60% to 80% of their excess body weight approximately 12 to 18 months following surgery. On average, patients are able to keep off 55% to 59% of their excess body weight after five years.
Also known as adjustable gastric banding, this procedure incorporates an adjustable band which is placed around the top portion of the stomach. The band diameter controls the amount of food going into the stomach and can be easily adjusted during follow-up office visits. Loosening (or tightening) the band determines how much food reaches the stomach and provides a feeling of fullness or satiety after meals. Lap-Band surgery generally produces a weight loss at a rate of approximately two to three pounds per week. Adjustments to the band are made until the overall desired weight loss is achieved. This procedure is minimally invasive, adjustable over a person’s lifetime, reversible and performed laparoscopically. Lap-Band® surgery patients achieve an average weight loss of 36% to 60% of their excess body weight approximately 12 to 24 months following surgery.
