Our Healthy Weight Management & Bariatric Surgery team typically performs two primary types of weight loss surgery: gastric bypass surgery and vertical sleeve gastrectomy surgery. These two surgeries are the most common and have been proven over time to be the most effective. Making just four to five very small incisions, we perform all procedures laparoscopically. All of Lancaster General Health's bariatric surgeons are highly skilled and experienced in laparoscopic surgery.
Before proceeding with bariatric surgery, it’s important to understand the scope and limitations of each surgical procedure and set realistic expectations. Bariatric surgery may not completely cure a medical illness. Even after surgery, weight management efforts must continue for the rest of your life.
Our staff will review the benefits and risks of each surgical option and help you decide which is right for you. Before meeting with one of our surgeons, you must attend one of our free bariatric seminars either in person or online. Our in-person seminars are offered approximately twice a month at our Healthy Weight Management Center. Our online seminar can be completed at any time from the comfort of your home.
Roux-en-Y Gastric Bypass
The Roux-en-Y gastric bypass weight-loss procedure limits food intake and calorie absorption, while allowing adequate nutrient intake. Gastric bypass surgery makes your stomach smaller and allows food to bypass part of your small intestine where most calories and nutrients are absorbed from the foods you eat. Because the new stomach, called a pouch, is so small, you feel full sooner when eating.
Due to the malabsorption aspect of the gastric bypass procedure, it is ideal for patients with conditions such as type 2 diabetes.
Vertical Sleeve Gastrectomy
Vertical sleeve gastrectomy is a minimally invasive procedure which reduces the size of your stomach by three or four ounces—roughly the size of a banana.This limits the amount of food you can eat to help you lose weight. In addition, the part of the stomach that produces a hormone called ghrelin that makes you feel hungry is removed. As a result, patients feel full for longer periods of time.
Patients who choose the sleeve gastrectomy can expect to lose up to 60 percent of their excess body weight.
The duodenal switch uses both restriction and malabsorption to help you lose weight. Developed in the 1980s as an alternative to gastric bypass, duodenal switch is the most complex of the current surgical options, combining aspects of sleeve gastrectomy and gastric bypass.
In this procedure, the size of the stomach is reduced and the small bowel bypassed (to a greater degree than gastric bypass) so patients will experience more malabsorption than other common bariatric procedures. This can lead to greater resolution of conditions like type 2 diabetes and high cholesterol, as well as greater long term weight loss. Patients undergoing duodenal switch need to take vitamins and supplements diligently due to the degree of malabsorption.
The adjustable banding system is an adjustable silicon "belt" that is wrapped around your stomach to help you lose weight. The adjustable gastric band reduces the amount of food you can eat at one time.
