Obesity is defined as having an excessive amount of body fat. Obesity is
more than just a cosmetic concern, though. It increases your risk of
diseases and health problems such as heart disease, diabetes and high
blood pressure. Being extremely obese means you are especially likely to
have health problems related to your weight.
The good news is that even modest weight loss can improve or prevent the
health problems associated with obesity. You can usually lose weight
through dietary changes, increased physical activity and behavior
changes. In some cases, prescription medications or weight-loss surgery
may be options.
