Sleeve Gastrectomy Treatment in Koramangala, Bangalore

Sleeve Gastrectomy

Gastric sleeve surgery is a weight loss procedure designed to help patients attain and maintain a healthy weight. The procedure significantly reduces the size of your stomach affecting the amount of food the stomach can retain.

With a smaller stomach, you feel satiated after eating less food. Over time, you lose weight as you eat less. The surgery also removes a part of the stomach that produces the  hormone named ghrelin  responsible for making you feel hungry.

Ghrelin also plays a part in blood sugar metabolism hence people with type II diabetes may not have to take their medication after sleeve gastrectomy. The surgery does not affect the functioning of your stomach to absorb nutrients from the food.

Why is a Sleeve Gastrectomy done?

Your doctor may recommend sleeve gastrectomy for weight loss  only after other methods such as exercising, taking weight loss medicines, and following a strict diet regime have been ineffective. However, that does not automatically qualify you for the procedure. You still have to meet the following general criteria:

  • Having a body mass index BMI over 40
  • Having severe weight related health problems despite having BMI under 40.

Your doctor may recommend sleeve gastrectomy so that you are not prone to weight related diseases such as:

  • Type 2 diabetes
  • High Blood pressure
  • High Cholesterol
  • Stroke 
  • Cancer

When to see a doctor?

If you have a family history of obesity and are experiencing chronic problems because of it, talk to your doctor.
