Gastric bypass surgery in response to severe obesity
Being very overweight is a great burden for those affected. The cause is not a lack of discipline, but lies in the genes. The hormones in the bowel that send a signal to tell you when you are hungry or full simply do not work properly. The body secretes hormones that stimulate the appetite. The hormones that produce a feeling of fullness after a meal are diminished. That’s why changing your diet rarely leads to the desired goal. Bariatric surgery helps to correct the control of hormones with various operations on the stomach. Weight loss then becomes possible.
Who is suitable for gastric bypass surgery?
Gastric bypass surgery is considered in cases of severe obesity. Many people have already tried changing their diet or exercise regime. These measures are rarely successful in reducing weight over the long term. Medications can decrease appetite, but are only effective as long as you continue to take them. Afterwards you will start to gain weight again. Overweight patients often have other secondary issues, such as diabetes or high blood pressure. Bariatric surgery is particularly advisable in such cases.
What happens in a gastric bypass operation?
The patient comes to the clinic for a few days before gastric surgery. Preliminary examinations such as a gastroscopy and ultrasound must be carried out. The surgery is performed under general anaesthetic. The surgeon makes small incisions in the abdominal wall, and the surgical instruments are then inserted through these incisions. This minimally invasive method is much gentler on overweight patients, there are fewer complications and the wounds heal more effectively. During the operation, part of the stomach and small intestine are removed, and the ends are sewn back together.
What are the important points to remember after gastric bypass surgery?
After gastric bypass surgery, patients remain at the clinic for a few days. During this time, their diet is overhauled and their wounds are allowed to heal. Because of the reduced size of the stomach, patients can only eat smaller portions of food for the rest of their lives. However, since regulation of the appetite is working normally again, this will not bother the patient much. The quality of the food eaten is now more important than the quantity. As there is less space in the intestine for food intake, this can lead to signs of deficiencies. Nutritional supplements can help here.
