What is Obesity?
Obesity is a disorder that involves having too much body fat, usually a body mass index — also known as BMI — of 30 or greater. It increases the risk of serious health problems. Obesity often results from taking in more calories than are burned by exercise and typical daily activities.
Body mass index, also known as BMI, is often used to diagnose obesity. Many health care professionals also measure the area around a person’s waist to help guide treatment decisions.
Treatments include lifestyle changes, medicines and weight-loss surgery.
