Obesity in Adolescents
Etiology of Obesity in Adolescents
The factors that influence obesity among adolescents are the same as those among adults. Most cases are external (eg, consuming too many calories and/or a low-quality diet), often in conjunction with a sedentary lifestyle. Genetic influences are common, and responsible genes are now being identified ( see also ). Parents may be concerned that obesity is the result of some type of endocrine disease, such as Hypothyroidism or hyperadrenocorticism, but such disorders are rarely the cause. Adolescents with weight gain caused by endocrine disorders are usually of small stature and have other signs of the underlying disorder.
