Surgical Weight Loss Options

There are three types of weight loss surgery that are commonly performed on overweight people. These surgeries either make the stomach volume smaller or cut down the digestion tract.

The most established weight loss surgery procedure performed these days is the Roux-en Y Gastric Bypass. This operation makes the stomach smaller and allows food to bypass a part of the small intestine. This procedure also minimizes the amount of food going into the stomach and the amount of food that is absorbed in the digestive system.

The stomach is either sewn closed or stapled at the upper half creating a smaller stomach on top. The intestines are then linked to the smaller stomach and food passes directly from one to another. In this way the stomach is separated into one small and one large section. The result of this is that less food will give the sensation of fullness and thus fewer calories will be consumed.

The food then passes through the shortened segment of the small intestine, allowing less food to be absorbed and this also results in fewer calories being absorbed by the body. The combination of getting full quicker and the lower absorption of calories lead to weight loss.

The Roux-en Y Gastric Bypass surgery has the benefits of a quick weight loss right after operation. The average weight loss for patients that go through a Roux-en-Y gastric bypass surgery is 60 to 80% of their excess body. This happens in most instances 12 to 18 months after the surgery. But after five years, patients are in average only able to keep off 55-59% of their excess body weight.

This procedure has a higher success rate than other forms of weight loss surgery. On the other hand, the Gastric Bypass is often further invasive as it is often performed as an open incision, and the time to recover is long. But in some cases the operation could also be performed laparoscopically, which means that the operation is performed as a keyhole surgery.

Biliopancreatic diversion is the most radical of the weight loss surgeries. In this operation, about three-fourths of the stomach is entirely removed and the remainder of the stomach is linked to the ending section of the small intestines.

There are quite a lot of disadvantages to this method like having a higher mortality rate, life long bone density loss, the dumping syndrome and anemia. The benefits to this weight loss surgery are that it gives the patients the biggest initial weight loss and that it is possible to feed as normal people.

The newer Lap band surgery makes a smaller stomach by an adjustable band which is positioned around the top segment of the stomach. The band makes it possible to regulate the volume of food going into the stomach. The band could be changed until the preferred weight loss is achieved.

The lap band procedure is in most cases suggested because of the shorter recuperation and smaller risks. The Lap band is also favored because it is reversible and flexible. Often patients go through a more even time of weight loss and are able to keep the weight off longer than with other surgical methods. Lap band surgery patients reach an average weight loss of 36 to 60% of their excess body weight after 12 to 24 months.

Before you get a weight loss surgery you should get as much information about the different weight loss surgery options as possible. It is important that you know both the advantage and the disadvantage of each method. One way to find more information is to use the Internet.
