Comparing Gastric Sleeve & Gastric Bypass Procedures

Gastric sleeve surgery has been growing in popularity as an option for people looking to lose weight. It is also known as laparoscopic sleeve gastrectomy (LSG) and is minimally invasive. On the other hand, gastric bypass surgery has been around for many years and is still the most common weight loss surgery.

How Are Gastric Sleeve and Gastric Bypass Different?

Gastric sleeve surgery is a minimally invasive procedure that involves removing a portion of the stomach. That reduces the size of the stomach and limits the amount of food that you eat. On the other hand, gastric bypass surgery is a more invasive procedure that involves surgically dividing the stomach into two parts and rearranging the intestines so that food bypasses most of the stomach. The way gastric bypass and sleeve surgeries are performed lays the primary difference between them.
