What is Gastric Bypass Surgery and Who is Applied to?
Thanks to gastric bypass surgery, food absorption is severely restricted in individuals. As the stomach shrinks, food intake is restricted and weight loss is achieved.
After gastric bypass surgery, which restricts food absorption, a small part of the stomach entrance is separated. The separated part is then sutured to the small intestine. In this way, the stomach is reduced and food intake is restricted and weight is lost. “Gastric Bypass”, which means creating a passage from stomach to intestines in general surgery, is generally preferred in diseases that cause restriction of gastric outlet. In obesity surgery, it is the name of the application in which a large part of the stomach is disabled.
Who Can Have Gastric Bypass Surgery?
Gastric bypass surgery, which has an important place in obesity surgery, is applied to overweight individuals. In addition, it is preferred in patients who cannot lose weight due to insulin resistance and therefore have joint disorders. It should not be forgotten that although the number of people who prefer tube stomach surgery has become popular, it is performed successfully. It can also be applied as revision surgery in people who have previously undergone gastric coating, gastric band and tube stomach surgery.
Tests and Tests Before Gastric Bypass Surgery
Before this surgery, the following tests and examinations are performed to the patients;
- Stomach endoscopy
- Hemogram
- Blood biochemistry tests
- Hormone tests
- Abdominal ultrasound
- Hepatitis test
- Lung respiratory test
- Lung X-ray
- ECG
- ECO and effort test if required by the doctor
After the necessary examinations and examinations are carried out, the factors that cause weight gain of the patients are checked. If a different disease is not detected, the necessary examination in terms of anesthesia is completed and the patient is informed about the surgery.

How is Gastric Bypass Surgery Performed?
This procedure is performed with closed surgery, ie laparoscopic application. With more than one small incision made, the abdominal area is reached with the ports placed through the incisions. Then the telescope device is connected to the camera and the area is entered. After these procedures, approximately 90 percent of the stomach is taken from the junction of the entrance of the stomach with the swallowing tube and the incision is closed. With the operation, a stomach pouch is created at the stomach entrance. The reason for the formation of the pouch is to deactivate the stomach and ensure that nutrients come to this area. The surgery continues with the removal of the part of the small intestine that goes to the large intestine. This part, which is cut up to 75 cm, is connected to the formed stomach pouch. The remaining part is combined with the intestine again. With the development of technology, incision, separation and joining processes are completed without any problems.
Pain and Incision Scars After Gastric Bypass Surgery
There is no serious pain after gastric bypass surgery. Because the operation is performed through the incisions made by laparoscopic, ie closed method. In addition, thanks to the painkillers to be prescribed to the patients, long-term pain will not be experienced after the surgery. The small incisions made make individuals happy in terms of aesthetics. From the 3rd month of the procedure, the wounds begin to heal and the incision scars disappear.
Nutrition After Gastric Bypass Surgery
The patient is tested for leakage 2 days after the operation. If there is no problem, liquid food intake begins. After gastric bypass surgery, liquid food intake will continue for the first 14 days and a puree-style diet will continue for the second 14 days. The nutritional habits of the patients regarding mineral and vitamin supplements will also be prepared by the doctor.
Things to Consider After Gastric Bypass Operation
Individuals should not use any medication after the operation. In other words, the drugs prescribed by the doctor should not be exceeded. Patients who can take a shower as soon as they leave the hospital should be careful not to open the seams. After the shower, the stitched area should be dried.
The risk of gaining weight again after this operation is low. However, individuals need to eat adequate and healthy. As a result, the successful completion of the operation can be achieved by changing all previously acquired consumption habits.
