Obesity is a health problem where your weight is higher than it should be. Doctors use a method called body mass index or BMI to measure whether you are at a healthy weight for your height. The doctor uses your weight and your height to determine your BMI. A high BMI can be an indicator of high body fat. Obesity is different from being overweight. Being overweight means your BMI is 25 or higher. Being obese means your BMI is 30 or higher. If your BMI is 40 or higher, you are considered severely or morbidly obese. Being obese may lead to many health problems. It may make it hard for you to breathe and move easily. It may raise your risk for illnesses like high blood sugar and heart disease.
