Surgeries For Weight Loss

There are different surgeries to reduce the weight. Some of them are:

1. Bariatric surgery
This surgery is for those who are over weight by more than 100 pounds and have Basal Metabolic Index of 40. In such obesity patients the surgery helps to reduce the weight much faster than the exercises, and the dietary solutions that they have already taken. The surgery restricts the food intake or hinders with the digestive system of the patient. This is done by either making the passage between the upper and lower part of the stomach narrow by banding or by making alterations in the intestine so that the food bypass the lower part of stomach, duodenum, jejunum. The first is the restrictive type and is by Adjustable Gastric Banding and Vertical Banded Gastroplasty. The second is of restrictive malabsorption type.

2. Gastric bypass surgery
This also like bariatric surgery is for patients with BMI over 40. By this surgery the food that the person intakes is allowed to bypass the stomach and a part of the intestine. Thus the person who has undergone surgery eats restricted amount of food in a meal and the body absorbs fewer calories resulting in the weight loss. The patients undergoing surgery have to follow a diet plan for certain time which is planned by the medical practitioners. They are first kept on the liquid diet and then their diet is gradually improved to semi liquid and then to a solid diet.

3. Liposuction
This is a type of cosmetic surgery in which the fat is removed from different parts of the body. The fat in the body part is sucked out through the vacuum device called cannula. Tumescent liposuction is common in which a sterile saline solution is injected in the body part where the liposuction is performed. In ultrasound liposuction the fat is liquefied by using sound waves. The desired result requires certain number of sittings. Liposuction is also common technique for cellulite removals.

Side effects
The surgeries do have their side effects. In liposuction the treated area can show increased sensitivity, necrosis or dying of the skin around the treated area, swelling and burning sensation.

In gastric bypass there may occur nutritional deficiencies especially of calcium and iron. This results in osteoporosis, anemia and other vitamin deficiency diseases. The risk of pneumonia increases. Other symptoms may include nausea, vomiting, diarrhea, dehydration and stomach ulcers.

With bariatric surgery also there are conditions of increased risk of pneumonia, kidney stones, blood clots in legs, thiamine deficiency besides nausea, vomiting and other nutritional deficiencies.
