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.
Bulimia Nervosa
Bulimia nervosa is an eating disorder characterized by repeated episodes of binge eating followed by behaviors intended to prevent weight gain, such as self-induced vomiting or misuse of laxatives. People may feel a loss of control during binge episodes and experience intense concern about body weight or shape. The disorder can occur at any body size and may not be obvious to others. Repeated compensatory behaviors can cause serious physical complications, including electrolyte disturbances, dental damage, gastrointestinal problems, and heart-related abnormalities.

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.
Bulimia Nervosa
Diagnosis of bulimia nervosa involves a detailed assessment of eating patterns, binge episodes, compensatory behaviors, body-image concerns, mental health, and physical health. Clinicians may use established diagnostic criteria together with interviews and questionnaires. Physical examination and laboratory tests can identify complications such as dehydration or electrolyte abnormalities. An electrocardiogram may be needed when purging or electrolyte disturbance creates a risk of heart rhythm problems. Assessment should also consider other eating disorders and medical conditions.
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.
Bulimia Nervosa
Bulimia nervosa cannot always be prevented, but early recognition of unhealthy eating patterns and body-image concerns may help reduce progression. Avoiding repeated restrictive dieting and promoting balanced eating habits can be helpful. Families, schools, and healthcare professionals can encourage healthy attitudes toward food, weight, and appearance. People showing recurrent binge eating, vomiting, laxative misuse, or intense fear of weight gain should receive professional assessment. Early treatment can reduce the risk of serious physical and psychological complications.
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.
Bulimia Nervosa
Risk factors for bulimia nervosa include a history of dieting, strong concerns about body weight or shape, pressure related to appearance, family or personal vulnerability to eating disorders, and certain psychological or emotional difficulties. Adolescence and young adulthood are common periods for onset, although the disorder can occur at any age. Social pressures, stressful experiences, and environments that emphasize weight or appearance may contribute, but no single factor causes bulimia.
