Gastric sleeve surgery, also known as vertical sleeve gastrectomy or sleeve gastrectomy, is one of the most successful and popular surgical weight loss procedures. This surgery has a successful track record in helping patients shed excess pounds to reduce health risks associated with obesity.

Looking for gastric sleeve near you? At West Medical in Lancaster, we perform most gastric sleeve procedures laparoscopically, using minimally invasive techniques with smaller incisions for less scarring and a quicker, easier recovery. Your health, safety, and comfort are the number one priority of our dedicated medical team.


Gastric sleeve surgery makes the stomach smaller, so you feel full a lot sooner, eat smaller portions, consume fewer calories, and lose a significant amount of weight. Nearly 85% of the stomach is removed, leaving a thin vertical tube or “sleeve” approximately the size of a banana. Surgical staples are used to keep your new, smaller stomach closed. As a portion of the stomach is surgically removed, this procedure is not reversible.

The part of the stomach removed in this procedure produces a hormone called ghrelin. This is the hormone the body produces to increase appetite when the stomach is empty or when a person is on low-calorie diet. Blood ghrelin levels decrease significantly after gastric sleeve surgery. Patients eat less and lose weight after this procedure, not only because they feel full faster, but also because the main source of the hormone causing them to feel hunger pangs has been surgically removed.


This procedure is used to achieve substantial weight loss in combination with a healthy diet, which means eating the right foods in the proper portions. You will also need vitamin and mineral supplements, as your overall food intake will be significantly reduced.

Your doctor will give you detailed instructions about what you should eat after your surgery. For approximately 4 weeks after the procedure, while you are healing, your stomach will be able to tolerate only small amounts of soft foods and liquids. We get a large portion of the water we need from our food. As your food intake will decrease substantially after surgery, you will need to sip water throughout the day to avoid dehydration.

Slowly, a little at a time, you will be able to reintroduce solid foods into your diet. It is important to chew your food well and to stop eating when you are full to avoid discomfort and nausea. We will recommend that you work with a dietician on planning healthy meals to provide the protein, vitamins, minerals you need, in addition to taking nutritional supplements.


With healthy eating and exercise, many gastric sleeve patients lose more than half of their excess weight and are able to keep it off for the long term. At West Medical, we focus not only on weight loss results after bariatric surgery, but also on improvements in obesity-related health conditions, longevity, and better quality of life.

Bariatric surgeries such as the gastric sleeve can lead to remission or improvement in Type 2 Diabetes. The American Society for Metabolism and Bariatric Surgery (ASMBS) reports that a large-scale review of 621 studies involving 135,247 patients found that bariatric surgery causes:

  • Improvement of diabetes in more than 85% of diabetics
  • Remission of diabetes in 78% of diabetics

ASMBS also reports that a large population study in which mortality rates of bariatric and non-bariatric patients were compared found a greater than 90% reduction in death associated with diabetes and a greater than 50% reduction in death associated with heart disease.

The U.S. Department of Energy has designated Lancaster as a “Clean City.” The City is a leader in improving air quality and raising public awareness of alternative fuels, while strengthening local economy.

Lancaster adopted the Blue Skies program in 1994, along with a resolution that the City will use alternative fuels whenever possible.
