What is Gastric Bypass?

Unlike gastric surgery, the bariatric surgery method, which restricts nutrient intake and alters intestinal functions and reduces nutrient absorption, is called “gastric bypass” or “Roux-en-Y”.

During the gastric bypass operation, a small pouch is first formed in the stomach, and then the formed pouch is connected directly to the small intestine. After gastric bypass surgery completed in two stages, the food that patients swallow when they eat first goes to the small stomach in the form of a pouch formed and then proceeds directly to the small intestine.

How to Make Gastric Bypass?

Gastric bypass surgery, which can be performed with both open and closed technique and which has been performed with closed technique frequently in recent years, consists of two stages. During the gastric bypass performed with special surgical instruments through the holes drilled from the abdomen, a new stomach is first created in the form of a small volume pocket. The small stomach created and the majority of the stomach are separated from each other and the majority of the stomach is disabled without removal from the body. In the second stage of the operation, the small intestine is shortened.

Shortened by an average of 50-75 cm, the small intestine connects to the new stomach created adjacent to the esophagus. The cut part of the intestine is reunited with the intestine about 70 cm away. After gastric bypass surgery completed in 1 – 2 hours, both food intake of patients is restricted and food absorption is reduced. Unlike gastric gastric surgery, the stomach and intestines cut during gastric bypass surgery are not removed from the body.

Advantages of Gastric Bypass Surgery

Thanks to gastric bypass surgery, the stomach is reduced, both nutrient intake is restricted and nutrient absorption (especially fat and sugar) is reduced because the small intestine is cut off. Thus, the weight loss process is accelerated.

Since the stomach is reduced after gastric bypass, patients start to get fed more quickly despite eating less.

The risk of joint disorders, sleep apnea, high blood pressure, high cholesterol and heart disease, which can occur due to excess weight, especially diabetes, decreases.

Patients may experience a feeling of satiety for longer because the point at which the new stomach formed during gastric bypass is connected to the intestine is narrower than normal.

Disadvantages of Gastric Bypass Surgery

Like all gastric reduction surgeries, gastric bypass surgery has major drawbacks.

Gastric bypasses may experience vitamin and mineral deficiency in the medium and long term if they do not comply with their nutrition programs. Lack of minerals and vitamins can lead to various health problems such as anemia, hair loss, decreased muscle mass.

After gastric bypass surgery, nausea, constipation and various intestinal problems may occur.

Hernia formation can be observed in the surgical area.

Dumping syndrome can occur if eaten quickly, since in this operation the pilor valves are not protected.

Gastric bypass surgery also does not guarantee weight loss or recovery of weight lost.
