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.

Vertical Sleeve Gastrectomy

Vertical sleeve gastrectomy is a laparoscopic weight-loss surgical procedure that staples the stomach into a tube (gastric sleeve), roughly the size of a banana. The gastric sleeve limits portion sizes, much like a gastric bypass pouch and a banded stomach. Also, by removing the portion of the stomach that secretes ghrelin, a hormone responsible for hunger, patients feel satiety for longer periods of time.

Duodenal Switch

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.

The stomach is stapled into a sleeve 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.

Adjustable Banding

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.
