Surgery is the most severe of the recommended treatments for obesity. Bariatric surgery is reserved for cases of severe obesity that have been resistant to all other methods of weight loss and weight control. There are two basic types of bariatric surgery (also known as gastrointestinal surgery), each with a different purpose. The risks for both are similar, as are the prospective results and outcome. Most Recommended Tips for The Last Resort: Weight Loss Surgery Restrictive Weight Loss Surgery
The first type of bariatric weight loss surgery is 'restrictive'. It includes the well-known 'stomach stapling'. The purpose of restrictive surgery is to restrict the amount of food that can be eaten at one time. Doctors create a small pouch at the top of the stomach that holds about one ounce of food, with a small opening at the bottom to hold food in the pouch and cause a feeling of fullness. After the surgery, a patient can eat no more than 3/4 cup to a cup of well-chewed bland food at a time without becoming nauseous. The intent of the surgery is to reduce the amount of food eaten by restricting the amount of food that can be eaten at once.
Variations of restrictive surgery include 'lap banding', in which the pouch is created by wrapping a silicone band around the upper part of the stomach. Since there is no need to cut into the stomach or intestine, the complication rate is lower than in standard restrictive surgery, and the recovery period is shorter.
The second type of bariatric surgery for weight loss is the malabsorptive variety. These are the more common type of surgery for treatment of obesity. The most well-known of the procedures is the gastric bypass. The purpose of gastric bypass and other types of bypass surgery is to prevent the effective absorption of nutrients from food eaten by 'bypassing' most of the intestine in the food's path through the body. The malabsorption results in significant weight loss and a reduction of appetite. Most Recommended Tips for The Last Resort: Weight Loss Surgery The possible side effects of gastric bypass surgery include:
Chronic diarrhea
Stomach ulcers
Foul-smelling stools and flatulence
Risk of nutritional and micro-nutritional deficiencies
Dumping syndrome - symptoms include faintness, fainting, nausea, sweating and diarrhea after eating
Patients seeking bariatric surgery are evaluated by a medical professional for suitability for the surgery. Candidates include those who are at least 80-100 pounds overweight, and who have shown little success with traditional weight loss methods. In additions, patients who have other physical problems which require weight loss may be candidates.
