Weight Loss Surgery – What Are Your Options?

Bariatric Surgery Techniques are classified in two different groups according to the way they help you to lose weight:

  1. Restrictive Procedures
  2. Malabsortion Procedures

Restrictive Procedures (Lap-band, Vertical Banded Gastroplasty)

Restrictive procedures decrease food intake by creating a small gastric pouch (with no more than 1 ounce capacity) that generates an early fullness sensation and stops the patient from further eating.

With a restrictive procedure you may lose 35% – 40% of your excess weight after gastric bypass surgery.
Malabsortive Procedures (Biliopancreatic Diversion)

This kind of surgery procedure alters the digestive flow, causing the food to be poorly digested and incompletely absorbed, especially carbohydrates and fat.

A third option is the combination of both restrictive, and malabsortive techniques. The most famous weight loss procedure, the RNY Gastric Bypass, uses a combination approach.

  1. It creates a small gastric pouch (as in the Restrictive Procedures)
  2. Diverts the digestive flow (as in the Malabsortion Procedures)

 

These two different mechanisms of surgery act together to produce the fastest results in sustained weight loss (75% – 80% of your excess weight).

“Sugarman, Capella and others have also reported that Gastric Bypass procedures resulted in significantly greater sustained weight loss when compared to patients undergoing gastric restrictive procedures ”

Gastric Bypass Surgery is regarded by many experts in the US as having the lowest reintervention rates and the best patient compliance with the new life style and diet.

There is an argument that this is only half the story!

Restrictive techniques like the Gastric Band and the Gastric Balloon procedures have a lower level of risk to the patient, as they are less invasive, and they have become the bariatric surgeon’s first choices in many countries outside of the US.
