Overweight and obesity are connected with increased risk of obesity related co-morbidities, such as T2DM, hypertension, cardiovascular diseases, dyslipidaemia and others, as well as in higher risk of some malignant diseases. In obese population there is 2.5-3.3 fold increased risk of renal cell carcinoma in comparison with non-obese population of similar age. It has been proven in many studies that for severely obese patients there is no other more effective treatment of their obesity and co-morbidities than bariatric. Bariatric surgery decreases mortality risks, treat existing, obesity related co-morbidities, and can act as prevention of onset of new obesity related co-morbidities. Moreover at the end bariatric surgery lowers economic burden of health care systems. Nowadays, bariatric surgery is considered to be standard treatment option and pathway in complex management of morbidly obese patients.
