What is bariatric surgery?
Bariatric surgery is a department trying to correct obesity that is becoming increasingly common. Bariatric surgery increases the quality of life and reduces the risk of disease. Obesity should not be known as something related to eating, that is, about external appearance. The disease, which increases proportional to the increasing weight, may reach such a degree that even a simple cough crisis can lead an obese person to death.
When is bariatric surgery needed?
The need for bariatric surgery is determined by the body mass index. Body mass index is calculated according to the weight and height of the people. According to your mass index, 25 – 30 stage is referred to as overweight, 30 – 35 stage as 1st degree obese, 35 – 40 stage as 2nd degree obese, 40 – 50 as morbid obese, 50 – 60 as super obese, 60 and above as super obese. In patients with a body mass index of 35-40, surgery may be recommended if there are no diseases such as diabetes, high blood pressure and heart disease are found.
Body mass index is calculated by dividing the body weight in kilograms by the square of the height.
What are the types of bariatric surgery? How is it performed?
Bariatric surgery tries to prevent problems due to weight. The primarily used method is gastric bypass. The stomach and small intestine are bypassed for approximately 1m. The operation takes approximately 2 hours. Gastric bypass surgery cannot be reversed. Another option is gastric banding. An inflatable band of silicone containing fluid about one finger wide is placed on the top part of the stomach. This is the system that enables the most weight loss in the long term compared to other surgical methods. In sleeve gastrectomy, a large portion of the stomach is removed and the exposed vertical edges are connected to a pipe shaped tube. Other options are a small bag placed vertically along the small curvature of the stomach with the help of surgical staples, emptied with a small outlet.
Some conditions are necessary for bariatric surgery. Some of the criteria are obesity duration of more than 5 years and the age of the patient being 20 to 60 years. The risk of death during surgery is less than 0.5%, but the danger may increase depending on age and weight. Bleeding in the suture areas may occur in overweight patients following bariatric surgery. The patient can be re-operated. Bleeding may occur in approximately 3% of patients. Although weight loss can be achieved at the same rate without surgery, bariatric surgery is better conventionally. The weight loss by the surgery decreases the mortality rate.
