One of the heritable, environmental and cultural factors may be effective for the formation of obesity as well as all reasons may also be combined.

Obesity Measuring

Body Mass Index- BMI is used to determine the obesity level. Body mass index is a value found by dividing the weight of a person in kilogram unit to the square value of height in metre unit.

BMI (kg/m2)): body weight (kg) / (height2)) (m)

Conditions to prevent surgery

Patients having serious psychological problem

Patients unable to comply with post-surgical treatment

Patients having substance and alcohol addiction

Benefits of obesity surgery

  • Post-surgery blood pressure measures are seriously improved for obese patients having hypertension problem. These patients quit taking blood pressure drugs in 60-70%.
  • Blood sugar levels are improved seriously for patients having type 2 diabetes. More than half of the patients may quit their anti-diabetic drugs.
  • Heart diseases risk significant decreases after surgery.
  • Sleep apnea problem in line with overweight is remedied.
  • Inhalation system problems are improved.
  • Life quality of patients are significantly improved as a result of the aforementioned benefits.

Surgery Types

Stomach Band

Stomach strap is an operation performed with laparoscopic method. Small stomach pouch is formed through a band placed under 3-4 cm of stomach inlet section. Most important advantage of the band is that it is adjustable. Tightness of the band may be increased or decreased according to patient monitoring. A port placed under skin to perform such adjustment. Since no absorption disorder occurs for patients having stomach band applied, generally no vitamin deficiency is found.

Post-surgical problems that may be encountered are as band sliding, erosion of the band, swallowing problems, band damage and port place problems.

Tube Stomach (Sleeve gastrectomy)

Most popular obesity surgical operation is the tube stomach operation. Surgery is performed successfully with laparoscopic method. Large portion of the stomach is removed with this surgery and approximately 25-30% of the total volume of the stomach is remained. Since the remaining stomach part is in tube shape, this surgery is called tube stomach.

In the surgery, upper section of the stomach called fundus is also removed. Therefore, levels of ghrelin hormone excreted from stomach fundus and as an appetizing hormone are reduced and appetizing control is easily performed after operation for patients.

Although capacity of the stomach is decreased in this surgery, no disruption occurs on the stomach functions. There is no risk of ulcer occurring. Since no absorption disorder occurs, less vitamin deficiency is encountered compared to bypass surgeries.

Gastric Bypass

Approximately 25-30 cc stomach volume is formed at the inlet of stomach in this surgery and small intestines in 100-150 cm distance away from the stomach are combined with this pouch. This surgery limits the eating and reduces the absorption. This operation is technically harder and having more risk and irreversible surgery. Long term results are similar with the tube surgery, therefore recently tube stomach surgery is preferred. Patients must receive vitamin support after operation.
