Research has shown that Bariatric Surgery (also called Weight-Loss Surgery or Obesity Surgery) is the BEST method for permanent weight loss. Additionally permanent loss of excess weight, can lead to a reduction or even elimination of many serious health problems, including diabetes, hypertension and obstructive sleep apnea.

The Surgical Weight Loss Institute at Good Samaritan Hospital offers a unique team approach to weight loss. Our program offers personal intensive pre-operative assessment, and continues to support patients beyond surgery. Our surgeons, dietitians, physician assistants, psychologists, and nurses work with you to insure a successful outcome.

Good Samaritan Hospital’s Bloodless Medicine Surgery Program is also available for individuals undergoing Bariatric Surgery when blood transfusion is not an option due to personal preferences, religious beliefs or biological conditions.

Gastric Bypass Surgery

  • Also known as Roux-en-Y gastric bypass, is a combination metabolic procedure that slows the absorption of food and decreases calorie intake by creating a small stomach pouch that gets connected to the small intestine.

Gastric Sleeve Surgery

  • Also known as Vertical Sleeve Gastrectomy, is a restrictive metabolic procedure that removes a portion of the stomach that produces ghrelin, the hormone that stimulates hunger. The smaller stomach size reduces food intake and decreases calorie consumption.

Revision and Conversion Procedures

  • Involves additional Bariatric Surgery should you not achieve lasting weight loss or experience complications from prior procedures. A revision retains or modifies your existing procedure, while a conversion replaces an unsatisfactory procedure with a different one — both can usually be performed minimally invasively.
