Sleeve Gastrectomy (or gastric sleeve) is a procedure with a history of a few years only. It seems to lead to a weight loss short-term, but there are no available follow-up data of 20-30 years as with the bypass. It is generally not recommended for patients with a very high BMI, those who have diabetes and those with gastroesophageal reflux disease. In these cases the gastric bypass is considered to be a far better choice.

How you lose weight with the gastric sleeve

In the sleeve gastrectomy procedure about 80 % of the stomach is removed from the body, leading to a weight loss thanks to:

  1. a)restriction (i.e not enough room in the remaining stomach for the patient to consume large volumes of food), and

  2. b)hormonal changes (because of the stomach removal, making the patient to feel less hungry).

The sleeve gastrectomy proceudre is performed laparoscopiccaly and the hospital stay is usually 1 day. The patient can return to his or her work within 2-3 weeks.

The intake of vitamins after a sleeve gastrectomy is mandatory.
