Obesity
Obesity is a chronic disease with a strong familial component. It predisposes one to develop conditions such as high blood pressure, type 2 diabetes, heart disease, stroke, sleep apnea, osteoarthritis, gallbladder disease and cancer of the breast, prostate and colon. The tendency toward obesity is fostered by lack of physical activity combined with high-calorie, low-cost foods. If maintained, even weight losses as small as 10% of body weight can improve one's health. Body Mass Index (BMI), waist hip ratio and body fat percentage analysis are some of the ways to quantify obesity. It can lead to a poor quality of life and impaired mobility. The mainstay of treatment for obesity is an energy-limited diet and increased exercise. Drug therapy may consist of sibutramine, orlistat, phentermine, diethylpropion, fluoxetine, and bupropion.
