A sleeve gastrectomy is a procedure that limits the amount of food you can eat by reducing the size of your stomach. Like other metabolic surgeries, it also helps to establish a lower, healthier body fat set point by changing the signals between the stomach, brain, and liver. Many experts now consider the sleeve gastrectomy as the new gold standard for weight loss surgery. It can help you lose weight without the nutritional risks of gastric bypass surgery.

The surgeon creates a small stomach “sleeve” using a stapling device. This sleeve will typically hold 50 ml to 150 ml and is about the size of a banana. The rest of the stomach is removed.
This procedure works in part by restricting the amount of food (and therefore calories) that can be eaten without bypassing the intestines and absorbed. By removing part of the stomach, there is a rapid reduction in the hormone “Ghrelin” which is thought to stimulate appetite. You will feel satisfied quickly.
Table 1: Health Improvements after Sleeve Gastrectomy A clinical study on sleeve gastrectomy showed the following health benefits.
|Health Problem (Comorbidity)||Result After Sleeve Gastrectomy|
|Type 2 Diabetes||56%||37%|
|High Blood Pressure||49%||29%|
|Obstructive Sleep Apnea||60%||33%|
