Our Procedures



Laparoscopic Gastric Bypass surgery reduces the size of the stomach and bypasses a portion of the small intestine. Gastric bypass surgery is both restrictive - allowing you to feel full quicker with smaller amounts of food, and is malabsorptive – decreases caloric absorption.

Gastric bypass is a significant bariatric weight loss procedure that is not reversible and requires permanent lifestyle changes. Before considering gastric bypass surgery patients must fully understand the lifestyle modifications that are required.

How it Works

During laparoscopic gastric bypass, the stomach is made smaller by creating a small pouch at the top of the stomach using surgical staples. The smaller stomach is connected directly to the middle portion of the small intestine (jejunum), bypassing the rest of the stomach and the upper portion of the small intestine (duodenum). Food consumed bypasses most of the stomach and the first section of the small intestine, limiting caloric absorption. Gastric bypass is neither a reversible nor an adjustable procedure.

Rapid & significant weight loss:

Patients can expect to lose approximately 70-80% of their excess body weight approximately 2 years after surgery.

Relief or resolution of obesity related health conditions:

In addition to weight loss, gastric bypass surgery can lead to significant health improvements including resolution or improvement of; type 2 diabetes, high blood pressure, heart disease, sleep apnea, acid reflux and cholesterol levels.

Combination Procedure:

Gastric Bypass is both a restrictive and malabsorptive procedure, in some cases it may be more effective in improving obesity related health conditions than purely restrictive procedures


Although guidelines vary, laparoscopic gastric bypass surgery is considered when your BMI in greater than 40 and you have one or more complications caused by your excess weight.
  • You have a BMI of 40 for higher
  • You suffer from obesity related health conditions
  • You have attempted to lose weight in the past without success
  • You are mentally capable
  • You are free from alcohol or chemical dependency
  • You want low maintenance surgery, no band adjustments
  • You are apprehensive about a the possible side effects of a LAGB implant (band slippage or band erosion)

Risks and Complications

It is important for patients to understand that there are risks and complications involved with general surgery itself. Some of the risks and complications related to general surgery are; Bleeding, pain, shoulder pain, pneumonia, complications due to anesthesia and medications, deep vein thrombosis, injury to stomach, esophagus, or surrounding organs, infection, pulmonary embolism, stroke or heart attack and rarely death (0.3%).

Complications specific to laparoscopic gastric bypass include; blood clots in the legs, leakage at the staple lines in the stomach, incisional hernias, narrowing of the opening between the stomach and small intestine, dumping syndrome, vitamin and mineral deficiencies and in rare cases death.
