Understanding obesity
Obesity is a chronic disease defined by having too much body fat. It differs from being overweight, which means weighing more than what is considered healthy for a person's height. In adults, obesity is generally identified using body mass index (BMI), a measure of body fat based on weight and height: a BMI of 30 or higher is classified as obesity, and a BMI of 40 or higher is considered severe obesity. There are typically no specific symptoms of obesity itself. Instead, a health care provider diagnoses it based on medical history and BMI, and may also check waist size, since fat carried around the waist can raise health risk. Providers sometimes order blood tests to help rule out underlying conditions that can contribute to weight gain. Obesity increases the risk of many other health problems, including type 2 diabetes, heart disease, high blood pressure, stroke, sleep apnea, osteoarthritis, and some cancers. At a high level, management centers on healthy eating and increased physical activity, with counseling, medicines, or weight-loss surgery added when appropriate. This is general information, not medical advice.
First-line treatment
Federal guidance from the NIH National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and the National Heart, Lung, and Blood Institute (NHLBI) identifies lifestyle change as the foundation of care: adopting a healthy eating plan and increasing physical activity. NIDDK notes that safe, successful weight-loss programs typically include an eating plan based on the calories and nutrients a person's body needs, at least 150 minutes per week of moderate-intensity aerobic activity such as brisk walking or cycling, and 14 or more counseling sessions over 6 months. Both NHLBI and MedlinePlus note that even a modest 5% to 10% weight loss can meaningfully improve health. Medicines or weight-loss (bariatric) surgery may be considered when lifestyle changes alone are not enough, and medicines are meant to be combined with lifestyle changes rather than used alone. A clinician individualizes the plan for each person. This is general information, not medical advice.
