Gastric bypass and gastric sleeve are both medical procedures. One of the ways to differentiate between the two procedures is by comparing how they work. Gastric bypass is a procedure that involves the rerouting of the intestines so that the intestines and stomach can be bypassed.
Gastric sleeve, on the other hand, refers to a medical procedure that ensures the removal of some parts of the stomach leaving the sleeve unaffected. Unlike in gastric bypass, where the intestines and stomach are rearranged to give a y-like shape, the gastric sleeve does not have anything to do with the intestines.
Another difference is that, though gastric sleeve and gastric bypass come with complications, the latter has more severe complications compared to the former. Another difference is that the gastric sleeve is not as expensive as the gastric bypass. However, both procedures are used to help patients achieve weight loss so they can eat less food because their stomachs can only hold less food.
Gastric bypass simply refers to a process whereby the top part of the stomach and the jejunum of the small intestine are connected together by a piece of the small intestine. This connection creates another route such that it bypasses the first part of the intestine (duodenum) and the stomach. This procedure is also referred to as the Roux-en-Y, simply because a Y shape is formed by the intestines after the completion process.
This procedure is introduced as a means to help patients with a high body mass of about 35 and above. When it comes to gastric sleeve, this is also a process whereby a higher percentage of the stomach is being removed. This leaves just a sleeve of the stomach, and it does not affect the intestines.
This procedure is also introduced to help patients who are considered morbidly obese to lose weight. It is introduced in patients with about 40 Body Mass Index and above. Most of these patients are always suffering from type 2 diabetes, hypertension, sleep apnea, and more.
