Overview
Obesity
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.
Anorexia Nervosa
Anorexia nervosa is a serious eating disorder characterized by restriction of food intake, significantly low body weight, an intense fear of gaining weight, and a disturbed perception of body weight or shape. People with anorexia may severely limit food, exercise excessively, or use other behaviors to lose weight. The disorder can affect nutrition, bones, the heart, hormones, and other body systems, and it can occur in people of different ages and backgrounds.

Diagnosis
Obesity
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.
Anorexia Nervosa
Diagnosis involves assessment of eating behavior, weight changes, thoughts about food and body image, and physical health. A healthcare professional may perform a physical examination and order tests to identify complications of inadequate nutrition or other causes of weight loss. Blood counts, electrolyte and kidney tests, liver and thyroid tests, protein measurements, urinalysis, electrocardiography, and bone-density testing may be used when appropriate. Psychological assessment also helps identify the characteristic eating and body-image concerns.
Prevention
Obesity
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.
Anorexia Nervosa
There is no guaranteed way to prevent anorexia nervosa, but early recognition of unhealthy eating behaviors and excessive concern about weight may allow treatment before severe complications develop. Healthy attitudes toward food, body image, and physical activity can be encouraged in families, schools, and healthcare settings. Avoiding harmful dieting practices and discussing persistent concerns about weight, eating, or body image with a qualified professional can support early identification. People recovering from an eating disorder benefit from continued medical and psychological follow-up.
Risk Factors
Obesity
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.
Anorexia Nervosa
Risk factors include a strong concern about body weight or shape, negative self-image, perfectionistic or highly rule-focused behavior, anxiety disorders, and certain social or cultural pressures related to appearance. Eating difficulties during childhood or adolescence may also be associated with increased risk. Anorexia commonly begins during the preteen or teenage years or young adulthood and is more frequently diagnosed in females, although it can affect males and people of all ages.
