TYPES OF WEIGHT LOSS SURGERIES
A well-qualified Surgeon / Aesthetic consultant will advise you which kind of surgery will be the best option during pre-surgery counseling.
There are two types of generic Weight loss surgeries:
1) Restrictive: In this type of surgery the size of the stomach is reduced or made limited, the normal stomach can hold around 3 pints of food but after this surgery, the stomach can only hold one ounce of food and later on with the time it stretches upto 2-3 ounce of food. Basically, it deals with restricting the food ingestion and slow downs the digestion.
2) Malabsorptive/Restrictive: In this kind of surgery the size of the stomach is restricted like above and a section of small intestine is bypassed or removed, this makes a lesser amount of calories to be absorbed by the small intestine and hence results into Weight loss.
SPECIFIC WEIGHT LOSS SURGERY OPTIONS
Once a type of weight loss surgery is selected, a specific surgical procedure is chosen :
1) Laparoscopic adjustable Gastric Banding: In this method, a inflatable band squeezes the stomach into 2 sections upper being smaller than the lower one. This surgery restricts the food holding capacity to about 1 cup per meal. It doesn't affect nutrients/calorie absorption.
2) Sleeve gastrectomy: In this method 75% of the stomach is removed, leaving a narrow tube or Banana shaped sleeve of the stomach , which holds less amount of food. It also not affects Nutrition/calorie absorption. This sometimes acts as a first step in weight loss process and is followed by gastric bypass or biliopancreatic diversion.
3) Gastric By-pass or Roux-en-y: This is the most common type of weight loss surgeries, it is both restrictive as well as malabsorptive. In this stomach is divided into two sections, upper being sealed from the lower portion. The upper part of the stomach is then attached to lower part of the small intestine which results in low-calorie absorption.
4) Duodenal Switch with Biliopancreatic Diversion: This is the more radical version of gastric bypass, in this, the most of the small intestine is by-passed or Duodenal switch. The section of intestine that is closed off is reattached at the end of the intestine so that bile and pancreatic juice can flow, this is called Biliopancreatic Diversion.
