For people suffering from morbid obesity, and for whom diet and exercise are insufficient to control their weight, weight-loss surgery might be an option. St. David's HealthCare offers free online and in-person seminars to answer questions and explain the benefits and risks of weight-loss surgery.

Conditions Treated

  • More than 100 lbs. over your ideal body weight, or
  • Have a Body Mass Index (BMI) of over 40, or
  • Have a BMI of over 35 and are experiencing severe negative health effects, such as:
    • Obstructive sleep apnea
    • Arthritis and Joint disease
    • high blood pressure
    • Heart disease
    • Type 2 diabetes
    • you are unable to achieve a healthy body weight for a sustained period of time, even through medically supervised dieting.

Roux-en-Y Gastric Bypass

Gastric Bypass is one of the most frequently performed procedures for morbid obesity in the U.S., and has shown to be significant in the resolution of type II diabetes. A gastric bypass restricts food intake and the amount of calories and nutrients the body absorbs. In this procedure, the surgeon creates a small stomach pouch and attaches a section of the small intestine directly to the pouch. This allows food to bypass a portion of the small intestine. Having a smaller stomach pouch causes you to feel full sooner and eat less; bypassing part of the small intestine means the body absorbs fewer calories.

Gastric Band

Laparoscopic Adjustable Gastric Band (Lap Band or Realize band) reduces the amount of food that can be eaten at one time. The band wraps around the upper part of the stomach, dividing the stomach into a small upper pouch that holds a small amount of food and a larger lower stomach. As a result, you'll feel fuller sooner and stay fuller longer. The band allows for normal digestion and absorption.

Sleeve Gastrectomy

A vertical sleeve gastrectomy procedure decreases the size of the stomach, limiting the amount of food that can be eaten at one time. During the sleeve gastrectomy procedure a thin vertical sleeve of stomach is created using a stapling device. The rest of the stomach is removed. The sleeve is about the size of a banana. As a result, you'll feel fuller sooner and stay fuller longer. Sleeve gastrectomy allows for normal digestion and absorption.

Revision Procedures

Revisional Bariatric Surgery is an option for patients that have previously undergone weight loss surgery that did not achieve the desired effect either due to complications or insufficient weight loss/weight regain.
