Bariatric Surgery Procedures

Surgical Weight Loss Options

Bariatric surgery is known to be one of the most effective and long-lasting treatments for obesity and many health-related conditions. The World Health Organization now recognizes obesity as a chronic, progressive disease resulting from multiple environmental and genetic factors. Bariatric surgery has shown to be a treatment for metabolic conditions including type II diabetes, hypertension, high cholesterol, non-alcoholic fatty liver disease and obstructive sleep apnea.

Gastric Bypass

There are two components to Gastric Bypass surgery. First, a small stomach pouch is created by dividing the top of the stomach from the rest of the stomach. Next, the surgeon attaches a Y-shaped section of thesmall intestine to the pouch. That creates a bypass for food, so it skips part of your digestive system. As a result, you absorb fewer calories and nutrients.  

Pros and Cons
 
  • - Produces significant long-term weight loss (60-80% excess weight loss)
  • - Restricts the amount of food that can be consumed
  • - May lead to increased energy
  • - Potentially result in complications
  • - Longer hospital stay than other bariatric surgeries
 

Sleeve Gastrectomy

The Sleeve Gastrectomy procedure is performed by removing about 80% of the stomach. The remaining stomach is a tubular pouch that resembles a banana. The new stomach pouch holds a considerably smaller amount than the normal stomach and helps to reduce the amount of food that can be consumed.

Pros and Cons

  • - Induces rapid and significant weight loss (more than 50% for 3-5+ years)
  • - Requires no foreign objects and no re-routing of the food stream
  • - Involves a short hospital stay of about two days
  • - Non-Reversible
  • - Potential long-term vitamin deficiency 

Biliopancreatic Diversion with Duodenal Switch Gastric Bypass

The Biliopancreatic Diversion with Duodenal Switch Gastric Bypass is a procedure with two components. First, a smaller, tubular stomach pouch is created by removing a portion of the stomach, similar to the sleeve gastrectomy. Next, a large portion of the small intestine is bypassed. The bypassed small intestine is reconnected to the last portion of the small intestine so that they can eventually mix with the food stream.

Pros and Cons

  • - Results in greater weight loss than other surgeries (60 - 70% or more excess weight loss in five years)
  • - Allows patients to eventually eat near normal meals
  • - The most effective bariatric surgery against diabetes compared to other weight-loss surgeries
  • - Has a higher complication rate and risk for mortality
  • - Strict adherence to dietary and vitamin supplementation guidelines are critical
