Gastric ByPass


Gastric bypass surgery is the most preferred obesity surgery in the world after sleeve gastrectomy. It is accepted as the gold standard method in the treatment of obesity.

Gastric bypass was the most performed bariatric surgery in the world before sleeve gastrectomy became popular.

How is Gastric Bypass done?

There are two stages of Roux-en-Y Gastric Bypass surgery. In the first stage, the stomach is reduced to a volume of approximately 30-50 ml. In the second stage, the first part of the small intestine is divided and the lower end is connected to the stomach. Its upper end is connected to the hindgut. Thus, both the amount of food intake is reduced as well as the amount of absorbed food. The calorie intake into the body is minimized.

Most importantly, rerouting the food flow in gastric bypass surgery provides early stimulation of gut hormones. This increases satiety, hunger is suppressed and the effects of type 2 diabetes caused by obesity are improved.

The Advantages of Gastric Bypass Surgery

Permanent weight loss lasts longer.

The amount of food that can be consumed is limited.

It can lead to circumstances that increase energy consumption.

Positive changes in gut hormones that reduce appetite and increase satiety are ensured.


The Disadvantages of Gastric Bypass Surgery

Technically it is a more complex procedure than gastric reduction (Sleeve Gastrectomy) surgery and can potentially cause greater complications. The procedure can lead to long-term vitamin/mineral deficiencies, especially vitamin B12, iron, calcium and folate deficiencies.

Generally, hospitalization is longer than for gastric reduction (Sleeve Gastrectomy) surgery. The procedure requires adherence to dietary recommendations, lifetime vitamin/mineral supplementation, and follow-up compliance.
