Weight Loss Through Bariatric Surgery


The treatment that is considered as life-saving for weight loss is bariatric surgery. The life of the obese person will be changed extensively with this treatment after he/she has encountered total failure in traditional and other medical strategies for weight loss. Many over-weight people will try to lose weight with the help of changed-diet, physical exercise and through drugs. Sometimes, it may not be possible for them to achieve the goal with the above methods. Bariatric surgery works well by interrupting the food intake by the patients and also by disturbing the process of digestion. The surgical procedure will not take away the fatty tissue.

Obesity indicated by being over-weight of 100 pounds higher than the usual weight that should exist at the given age and height is found to be the second most cause of death in the United States. It is statistically estimated that about 18 million people are suffering from obesity. Hence, the weight loss surgical procedures have gone higher from 16,000 cases in 1990 to 180000 by 2005. This estimation was made by the American Society for Bariatric surgery.

Types Of Bariatric Weight Loss Surgery

Bariatric Surgery

This type of surgery is known to induce loss in body weight by reducing the food quantity that is consumed by the person or by inhibiting the digestion process. There are 3 kinds of bariatric surgery.


Restrictive Surgery

This type of surgery is also known as Lap-band procedure. The stapling of stomach or vertical banded Gastroplasty or the sleeve Gastrectomy will physically restrict the amount of food that is consumed by the person by decreasing the stomach size or to the extent it can enlarge.


Combined Procedures

The surgical procedure called Roux-en-Y gastric bypass surgery functions same as the restrictive surgery. This procedure involves rerouting the digestive system such that the food will bypass the stomach for most of its volume.

These combined procedures will cover up almost 85 percent of all the bariatric surgeries performed in the United States.

Mal Absorptive Procedures

Biliopancreatic diversion bypass surgery that is classified under this category will not function by limiting the food intake physically. This procedure will allow the body to absorb less calories of energy and nutrients from the food by generating the bypass for quite a length in the intestine.

For over-weight patients who cannot withstand the restrictive and combined surgeries, they are suggested with the surgery that is done in two separate and small episodes.

Laparoscopy And Open Surgery

Some of the bariatric surgeries are performed as open surgery which would require a large incision in the abdomen while some of the surgeries can be performed with laparoscopy. Laparoscopy is done by making small cuts in the abdomen and inserting small instruments through these cuts.

In the laparoscopic surgery, the camera and the telescope are placed towards the organs of the patient and the instruments used for surgery are kept towards the video monitor. Laparoscopy is less invasive, less time can be spent in the hospital, less post-operative care is required, pain after operation will be minimal, and the infection risks are also reduced compared to that of invasive procedures or open surgery.

But, all these risks cannot be entirely eliminated in this procedure. Sometimes, taking into consideration of the body weight of the patient, the shape of the body and the extent of prior surgeries, laparoscopy will not be suggested. Instead, open surgery will be recommended for bariatric procedure.
