Weight Loss Surgery

Severe obesity can be treated with surgery when other attempts at weight loss have been unsuccessful. In order to determine your appropriateness for surgery, a comprehensive evaluation is performed by a team of health professionals.  This evaluation includes a health assessment, physical examination, dietary assessment and psychological evaluation.  A weight history will be taken, paying particular attention to all attempts at weight loss in the past.  Blood tests, x-rays, and various other tests will be requested to assess your overall health status, and thereby determine your individual risk for complications during or after surgery.


There are several weight loss procedures being performed. All are performed laparoscopically, through several small incisions.  These procedures work by either limiting the amount of food you can eat, limiting the amount of nutrients your body can absorb, or a combination of the two.  Your surgeon and weight management team can help you determine which surgery best fits your lifestyle and weight loss goals.

Sleeve Gastrectomy

During sleeve gastrectomy, the stomach is reduced to about 25% of it's original size, resulting in a stomach pouch about the size of a small banana.  This limits portion size, helping you feel full after eating just a small portion of food. Patients tend to lose 40 to 60 per cent of their excess weight over 12 to 18 months after surgery.

Gastric Bypass

The gastric bypass, a procedure which limits both portion size and absorption, is one of the most commonly performed procedure in the United States today. Patients tend to lose 50 to 70 per cent of their excess weight over 12 to 18 months after surgery.

Revisional Surgery

Laparoscopic adjustable gastric banding which works solely by limiting portion size is being performed in increasing numbers over the past 5 years. Patients tend to lose 40 to 60 per cent of their excess weight over 24 or more months after surgery. The LapBand can be adjusted to control appetite and weight loss. Adjustments are simple, painless procedures which are performed in the office.

Some patients do not achieve their weight loss goals after surgery. Revisional procedures can be considered for patients who have expereinced weight regain after surgery, or for those patients who have not lost the desired amount of weight after surgery.
