Obesity is a culmination of multiple factors including lack of exercise and poor dietary habits. Obesity and related diseases like diabetes have gained epidemic proportions in many developed countries. According to the World Health Organisation (WHO), obesity nearly doubled worldwide from 1980 to 2008. Some obesity may be related to an underlying hormonal problems.
The true perils of obesity lies in its associated metabolic disorders (including diabetes, hypertension, hypercholesterolemia), and the complications downstream as a result of these metabolic disorders. These complications include heart disease, stroke, sleep apnea, gallstones and even cancers. With proper management of obesity and these metabolic disorders, the risks of many of these serious complications can be reduced.
