Gastric bypass surgery is the most preferred obesity results in the world following sleeve gastrectomy. It is recognized as the gold standard method for the treatment of obesity. It was the obesity surgery which used to be performed most in the world before the sleeve gastrectomy became popular.
How is the gastric bypass applied?
Roux-en-Y Gastric Bypass surgery comprises of two stages. At the first stage, the stomach is reduced up to approximately 30-50 ml volume. At the second stage, the initial part of small intestine is removed and its lower part is joined with the stomach. Its upper end is joined with the intestine. In this way, quantity of food taken is reduced and all the food cannot be absorbed. Accordingly, calorie taken is minimized.
Most importantly, redirecting the food flow in the gastric bypass surgery enables early-stimulation of enterogastrone. By this means, fullness increases, hunger is suppressed and effects of type 2 diabetes caused by the obesity are improved.
- Permanent weight loss is longer.
- Quantity of food to be consumed is limited.
- It may cause conditions increasing energy consumption.
- It achieves positive changes in the enterogastrone reducing the appetite and increasing the feeling of fullness.
It is a technically more complex procedure than the sleeve gastrectomy surgery and it may potentially cause more severe complications.
It may cause long-term vitamin/mineral deficiency, especially vitamin B12, iron, calcium and folate deficiency.
Hospitalization term is generally longer than the sleeve gastrectomy.
Diet recommendations, lifelong vitamin/mineral support and follow-up recommendations should be obeyed.
