Body mass index (BMI)

Obesity

Obesity is a medical condition where a person has an excessive amount of body fat, which can lead to serious health problems. It's usually determined by measuring a person's body mass index (BMI), which is calculated by dividing their weight in kilograms by their height in meters squared. A BMI of 30 or higher is considered obese. Obesity can increase the risk of developing health problems such as heart disease, diabetes, stroke, and some cancers. Symptoms of obesity can include difficulty breathing, sleep apnea, joint pain, and fatigue.
