Weight Loss Sugery: What is this phenomenon?

The weight loss surgery is the surgical operation for the dangerously obese people. It is recommended to the people who has more than 40 Body Mass Index (BMI). With less than 40 upto 30 this can also be performed but as it has some risks involved with it, so doctors do not recommend it to these overweight people. The surgery results in quick weight loss to the obese people as it does reduce the size of the stomach. This is being done by a medical device called gastric banding device.

This gastric or lap band is a silicon device which is placed at the top and around the stomach. Choosing this kind of surgery is really a very serious step as there is pain and risks are associated with it so it is not that easy option. With the placement of the band there is created a small pouch at the top of the stomach. This pouch holds almost 100 to 200 grams of each meal food. As this pouch is at top so its get full first and then it slowly transfers the food to the lower. When the upper part gets full then a message from the stomach to the brain is sent, that is stomach is full. This phenomenon helps the victim to perform weight loss by less diet.

There is not only a single type of weight loss surgery, there are few others also. The gastric band surgery is called Restrictive weight loss surgery and the other is Malabsorptive weight loss surgery. The Malabsorptive surgery works by the changing the way how you eat food that is whay this is more invasive surgery. This is the next step to the resistive surgery which is after altering the stomach, this surgery alters the digestive system by removing some part of it. This is more dangerous and is now prohibitted beacuse of its too many side-effects.

There are other surgeries also which depends upon doctor recommendations as they have some variations from each other.

Sleeve Gastrectomy Surgery

This is also a form of resistive surgery in which is also done with a laparoscope as the gastric band surgery is also done with this. In this surgery, the 75% of the stomach is removed and a tube or sleeve is then inserted which gets connected to the concerned intestines. The operation for Sleeve Gastronomic Surgery is comparatively lower risky and is a first step towards weight loss for dangerously obese person. But as it is first step so may be later there would be more operations for the patient.

Biliopancreatic Diversion Surgery

This is another version of the gastric bypass surgery in which also the 70% part of the stomach is being removed and the less part of the stomach and the less intestine is bypassed. Now this type of surgery lessens some risks associated with the Gastric Bypass which are malnutrition, dumping syndrome and ulcers etc which are very common side effects of the surgeries. Besides, this is a most risky surgery as the death ratio due to this surgery is 2.5% to 5% almost.

These are the common weight loss surgery techniques which are being performed in the US hospitals and worldwide. Each has different variations, risks, Pros and Cons associated with it. The selection of the surgery depends upon the person's health and body type and most important is what your surgeon recommends you. So that's why always concern a capable surgeon which would have enough experience in the weight loss surgeries operations. Moreover do not think of surgery until your BMI reaches above the 40 and you have failed to perform quick weight loss by different means.

Gastric Bypass Surgery

This is the most widely used technique of all the surgeries and it is vrey common is the USA as 80% weight loss surgeriesperoformed in USA are Gastric Bypass Surgery. In the operation of the Gastric Bypass surgery, the stomach is divided into two parts in upper and lower. The both part then connected with  a shortcut that bypasses a part of stomach and the small intenstine which means the skipping of the digestive track which will make digestive system to absorb less calories.
