[Contemporary methods of treatment of morbid obesity].

Surgical treatment of morbid obesity appears to be more cost-effective than medical treatment. Moreover many medical treatments fail in the long term especially in cases with BMI > 40 kg/m2. That's why surgical treatment was introduced. Two kinds of procedures, gastric restrictive and gastric bypass, have resulted from these years of clinical investigation. Mentioned above surgical treatment produce efficient weight loss during several months after operations. Weight reduction surgery has been reported to improve several comorbid conditions. Minimal invasive procedures are waiting for randomised studies.
