How Does Weight loss surgery work?

The principle of this weight loss surgery is to confine the intake of food and drink and to limit the absorption of the food in the intestine. This reduction of nutrients and calorie absorption enables the patient to lose weight. In this modern medical era, some teens and adults are potential patients for minimally invasive laparoscopic bariatric surgery. This is more advantageous than the other types of weight loss surgery options.

Laparoscopic Bariatric surgery (weight-loss surgery) includes a variety of procedures performed on people who are obese. This weight-loss operation proceeds by reducing the size of the stomach with an implanted medical device (gastric banding) or through the removal of a portion of the stomach (sleeve gastrectomy) or by resecting and re-routing the small intestines to a small stomach pouch (gastric bypass surgery).

In the trial conducted by Swedish prospective, patients with (BMI) 34 or more for men and 38 or more for women underwent various types of bariatric surgery and were followed for an average of 11 years. Surgery patients had a 23.7% reduction in mortality (5.0% vs. 6.3% control).

Diabetes Surgery | Obesity treatment

Type 2 diabetes mellitus is an important component of metabolic syndrome which includes obesity, hypertension, and dyslipidemia. The concept takes origin from Bariatric (also called Obesity surgery) which was initially intended to treat Obesity permanently. But it was noticed that most patients with diabetes, this was completely cured over a follow up of 10-15 yrs. Further research and scientific data from our Institute and other pioneer institutes in the world have shown that this was related to certain hormonal changes that bring diabetes under remission permanently. Hence this hormonal concept was further studied and the results have shown promising results in control of diabetes even in patients using large doses of insulin and also inadequate control in-spite of various medication usage. Hence this is ideally suited for those patients who want to get rid of their insulin shots and also not able to achieve diabetes remission in-spite of maximum medical therapy.

Especially with India becoming the diabetic capital and more and more usage of insulin this diabetic surgery is possibly the only solution in this subgroup of patients. A recent Level I evidence that compared Bariatric surgery and medical therapy has clearly shown that surgery for diabetes provides most effective diabetic control in the short and long term compared to medical therapy.
