Obesity Health Center

Although body fat is usually easy to detect, obesity is not necessarily easy to diagnose. That's because varying amounts of muscle mass and how much water the body retains can affect body weight.

Many health professionals use body mass index (BMI) to determine whether patients are obese. BMI is body weight in kilograms divided by height in meters. In general, a BMI of 30 or higher is obese.

Other symptoms of obesity include becoming winded easily, feeling tired during the day and sore joints.
