Gastric bypass surgery is the most preferred obesity surgery after sleeve gastrectomy in the world. It is accepted as the gold standard method in obesity treatment. Before sleeve gastrectomy became popular, it was the most common obesity surgery in the world.
How is Gastric Bypass done?
There are two stages of Roux-N-Y Gastric Bypass surgery. In the first stage, the stomach is reduced to approximately 30-50 ml in volume. In the second stage, the first part of the small intestine is divided and the lower end is joined with the stomach. The upper end is combined with the last intestine. Thus, both the amount of food taken is reduced and not all of the food taken is absorbed. The amount of calories taken into the body is minimized.Most importantly, rerouting the food flow in gastric bypass surgery provides early stimulation of intestinal hormones. In this way, satiety increases, hunger is suppressed and the effects of type 2 diabetes caused by obesity improve.
Advantages of Gastric Bypass Surgery
Permanent weight loss takes longer.
It limits the amount of food that can be consumed.
It can lead to conditions that increase energy consumption.
It provides positive changes in gut hormones that reduce appetite and increase satiety.
Disadvantages of Gastric Bypass Surgery
Technically, it is a more complicated procedure than sleeve gastrectomy and can potentially lead to greater complications.It can lead to long-term vitamin / mineral deficiencies, especially vitamin B12, iron, calcium and folate deficiency.Generally, the hospital stay is longer than the gastric reduction (Sleeve Gastrectomy) surgery.It requires compliance with dietary recommendations, lifelong vitamin / mineral support and follow-up compliance.
