WHAT IS SLEEVE GASTRECTOMY?
Doctor For Hernia Surgery In Mumbai
The Sleeve Gastrectomy is a type of restrictive weight loss surgery. Sleeve Gastrectomy causes weight loss by restricting the amount of food that a person can consume before feeling full.
The size of the stomach is reduced to about 10% of its original volume, leaving behind a stomach measuring 80-100 ml. This results in a limited capacity of food intake.
How does a Sleeve Gastrectomy help you lose weight?
After a Sleeve Gastrectomy, the amount of food you can eat in one sitting is reduced. Because of this, the brain utilises the fat stored in your body for its energy needs. This burns the excess fat in your body, thus helping you lose weight.
Also, the fundus of the stomach is cut. This is the area of the stomach which produces the hunger hormone Ghrelin. Since the source of your hunger hormone is removed, you do not feel hungry all the time, and are satisfied with the small amount of food you eat without feeling tired or weak.
Does a Sleeve Gastrectomy help with my medical diseases like Diabetes?
There have been multiple reports in medical literature proving the beneficial effects of a Sleeve Gastrectomy not only in losing weight, but also in the improvement of medical diseases such as Diabetes, Hypertension, Sleep Apnea and many more.
Who can undergo this procedure?
Anybody with a BMI of > 37.5 kg/m2 or >32 kg/m2 with medical diseases can undergo a Sleeve Gastrectomy. Sleeve Gastrectomy is typically performed on individuals who do not suffer from severe co-morbidities and are young. This surgery is also done as first line surgery on patients who are too heavy to tolerate other types of weight loss surgeries (like the Gastric Bypass) with the expectation that a second surgery will be performed once weight has been lost.
Are there any side effects of a Sleeve Gastrectomy?
Usually there are practically no delayed side effects of a Sleeve Gastrectomy.
Some patients may develop GERD (reflux disease), but this can be corrected with lifestyle changes and medications. Some patients may have nutritional deficiencies post weight loss surgery, but these are easily preventable by taking regular multivitamin and multi mineral supplements as prescribed soon after surgery.
