Abstract Obesity is increasingly recognized as a worldwide major public health problem .Waist circumference, skin fold thickness and body mass index (BMI) are the most useful non-invasive clinical measures to define obesity. Obesity is defined when a body mass index (BMI) of 30 kg/m2 or greater while overweight is considered when (BMI) falls between 25- 29.9kg/m2. Egypt is a country where the problem of obesity is of epidemic level. Obesity is clearly more prevalent in women and it is more common in the elderly, but it is also increasing in children nowadays. The mechanisms behind obesity are still controversial. Obesity is often considered as a life style disease caused by overeating and/or decreased physical activity. Obesity may result from environmental, endocrinal or genetic factors. Environmental factors include dietary choices, socioeconomic status, behavioral factors, inactivity and sedentary life style, psychological factors and some drugs. Primary endocrine disease (eg, Cushing’s syndrome) is rarely the cause of obesity; however, hyperinsulinemia and diabetes are well-known consequences of obesity. Obesity is known to significantly affect both skin and systemic physiology. With growing numbers of obese patients, it will be increasingly important for dermatologists to be able to modify and adapt topical and systemic dermatologic therapies for obese patients. |
