What is Obesity?
Obesity is a body weight that exceeds the norm by 20 % or more. This condition results when calorie intake consistently exceeds metabolic demands. Theories to explain this condition include psychological factors, hypothalamic dysfunction of hunger and satiety centers, genetic predisposition, abnormal absorption of nutrients, and impaired action of GI and growth hormones and of hormonal regulators such as insulin. An inverse relationship between socioeconomic status and the prevalence of obesity has been documented, especially in women.
Obesity in parents increases the probability of obesity in children. Weight reduction and maintenance of proper weight are the goals of treatment, which includes a low-calorie diet, behavior modification, aerobic exercise, and social support.
