Obesity
Moderate
Obesity is a chronic disease involving excess body fat that can affect health and increase the risk of other conditions. Body mass index, or BMI, is commonly used as one measure of weight relative to height, although it does not directly measure body fat and has limitations for individuals with high muscle mass or reduced muscle mass. Obesity can affect children and adults and results from multiple interacting factors.

When to Seek Medical Attention
Obesity generally requires planned medical assessment and long-term management rather than emergency treatment. Seek professional care when weight is associated with diabetes, high blood pressure, sleep apnea, mobility problems, or other health complications. Urgent assessment is appropriate for severe breathing difficulty, chest pain, sudden neurological symptoms, or another acute medical problem.

Chest Pain

Weight Gain
Causes 3
Obesity develops when energy intake and energy use remain out of balance over time, but the causes are more complex than food intake and exercise alone. Genetic, biological, environmental, social, behavioral, and economic factors can influence body weight. Certain medicines and medical conditions may contribute. Sleep, stress, eating patterns, physical activity, and the availability of healthy foods can also affect long-term weight.
Obesity
Sedentary Lifestyle
Stress
Risk Factors
Risk factors include a family history of obesity, limited physical activity, eating patterns that provide more energy than the body uses, inadequate sleep, chronic stress, certain medicines, and some medical conditions. Environmental and social factors can influence access to nutritious foods and opportunities for physical activity. Risk also varies with age, life stage, genetics, and individual biology.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis involves assessment of weight, height, BMI, waist size, health history, and physical activity. A healthcare professional may review previous weight changes, eating patterns, medicines, and medical conditions. Blood tests or other investigations may be used to identify obesity-related conditions or possible contributors. BMI is useful for population and clinical assessment but does not distinguish fat from muscle or show where body fat is distributed.
Prevention
Key Prevention Tips
Healthy eating patterns, regular physical activity, adequate sleep, and long-term attention to weight can help reduce the risk of obesity
Prevention strategies work best when they are realistic and sustainable rather than based on rapid weight loss
Children and adults benefit from supportive environments that make nutritious foods, movement, sleep, and healthy routines easier to maintain
People with medical or medication-related contributors should discuss them with a healthcare professional
