[Comorbidities and complications of adiposis].

Overweight and obesity are associated with a high number of complications and co-morbidities. Obesity can affect almost all tissues and organs of the body. Obesity is associated with the components of the metabolic syndrome and is the leading cause of type 2 diabetes. Either obesity itself or co-morbidities of obesity are responsible for the increased cardiovascular risk. The increased overall mortality risk is due to cardiovascular and other complications like the higher prevalence and incidence of malignant tumors. Other complications of obesity like the polycystic ovary syndrome or the obstructive sleep apnea syndrome are relatively unknown but important and frequent. Medical care of people with obesity should focus not only on weight loss but also on complications and co-morbidities.
