There are many types of bariatric surgeries performed to treat obesity worldwide. Gastric bypass is one of the methods, which works on the basis of two factors to attain permanent weight loss in obese patients. It utilizes both a decrease in stomach size and a partial bypass of the small intestine to limit calorie intake. Gastric bypass surgery is also commonly referred to as Roux-en-Y weight loss surgery. This surgery is typically performed by a qualified surgeon in a hospital under general anesthesia.
This type of gastric bypass surgery is conducted on the person whose BMI or Body Mass Index is above 40. Doctors always recommend to loose weight naturally by following fitness programs and diet plans. Any kind of surgical method should be the last option to be tried due to the risks and complications involved in it. In Roux-en-Y method the stomach is cut into two parts to create a pouch out of the smaller proximal (near) portion. This small pouch or small stomach is then attached to the small intestine thus bypassing a large part of the stomach and entire duodenum. It is quite fruitful in achieving permanent weight loss goals as the small stomach holds less food and gets filled quickly resulting into less food intake. And, bypassing a large part of the intestine reduces the absorption of fat in the body. The entire procedure is done by laparoscopy and also called Roux-en-Y anastomosis or Roux-en-Y gastrojejunostomy. It is carried out by small incisions and generally has a more rapid recovery.
Roux-en-Y gastric bypass surgery is a very common method used in weight loss treatment. It has high success rate and low mortality rate as compared to other treatments. It has given hope to thousands of people worldwide and successfully being used to conquer obesity problems in all age groups. Like all surgeries even this method has some risk and complications associated to it. It has been observed that limited absorption of vitamin B-12 and iron has caused anemia in many patients. Lack of calcium in the body can lead to osteoporosis and metabolic bone disease. People who undergo this procedure are required to take nutritional supplements that usually prevent loss of valuable nutrients. The more severe is the procedure greater the risk of nutritional deficiencies. Patients undergoing this surgery need close monitoring until they resume normal digestive process and might have to use special nutritional foods and medications lifelong.
