Eating disorders (anorexia, bulimia)
Anorexia nervosa and bulimia nervosa are serious mental health conditions that affect eating habits and thoughts about body weight or shape. Anorexia usually involves restrictive eating, an intense fear of gaining weight, and can lead to dangerously low body weight. Bulimia often includes episodes of binge eating followed by behaviors such as vomiting, laxative use, excessive exercise or fasting to prevent weight gain.
Common symptoms
Symptoms can include weight loss or fluctuations, dizziness, fatigue, slow heart rate, irregular or absent menstrual periods, gastrointestinal problems, dental erosion (especially in bulimia), electrolyte imbalances, preoccupation with food or body size, ritualized eating or avoidance of meals with others, secretive behavior around food, mood changes, anxiety, and distorted body image.
Causes and risk factors
Eating disorders develop from a mix of biological, psychological and social factors. Risk can increase with a family history of eating disorders or other mental health conditions, genetic predisposition, perfectionistic or anxious personality traits, exposure to dieting or weight-focused messages, cultural pressure to be thin, major life transitions, stress, or a history of trauma or bullying. There is no single cause; multiple factors usually contribute.
Diagnosis
A qualified professional, such as a primary care clinician, psychiatrist, psychologist, or eating disorder specialist at TidalHealth, will diagnose these conditions through medical evaluation and mental health assessment. This typically includes a physical exam, checking vital signs, lab tests to monitor electrolytes and organ function, and questions about eating habits, thoughts about weight, and behaviors. Prompt evaluation is crucial, as eating disorders can have life-threatening complications.
Complications and outlook
Anorexia and bulimia can cause serious health problems, including heart issues, loss of bone strength, severe electrolyte disturbances, gastrointestinal damage, and, in some cases, death. Early recognition and treatment improve recovery chances. With proper medical, nutritional, and psychological care, many people make significant progress, though ongoing support and relapse prevention are often needed.
How are anorexia and bulimia different?
Anorexia involves ongoing restriction of food, low body weight, and a strong fear of gaining weight. Bulimia includes binge eating followed by behaviors to prevent weight gain, such as vomiting, laxatives, or excessive exercise. Some people may show symptoms of both.
What are early signs I should watch for in myself or someone I care about?
Early signs include intense focus on food, calories or dieting; sudden weight changes; avoiding meals with others; frequent bathroom trips after eating; purging signs like sore throat or dental problems; mood changes; social withdrawal; and restrictive or ritualized eating habits.
Are eating disorders life-threatening?
Yes. They can cause heart rhythm problems, electrolyte imbalances, organ damage, and increased suicide risk. Anorexia carries one of the highest mortality rates of any mental health condition. Seek medical attention immediately for fainting, chest pain, abnormal pulse, severe dizziness, confusion, trouble keeping food or fluids down, or signs of dehydration.
How are eating disorders treated?
Treatment usually involves a team approach, including medical monitoring, nutritional guidance, therapy such as cognitive behavioral or family-based therapy, and sometimes medication for anxiety, depression, or binge-purge behaviors. Care may range from outpatient therapy to hospital treatment depending on severity.
Can someone fully recover?
Many people recover or make significant improvements with the right treatment and support. Recovery involves restoring health and addressing emotional needs. It often takes time, and setbacks can happen, but staying connected to support systems improves long-term outcomes.
When should I seek emergency help?
Get emergency care for fainting, loss of consciousness, chest pain, trouble breathing, seizures, severe abdominal pain, inability to keep food or fluids down, extreme heart rate, or severe dehydration. Seek immediate help if there is concern for self-harm.
How can family and friends help?
Offer support with kindness and without judgment. Encourage medical evaluation, help find resources, attend appointments, and focus on activities together rather than just food or weight. Family-involved therapies can be especially helpful for younger people. Caregivers should seek guidance from professionals experienced in eating disorders.
Are medications helpful?
Medications can help some people, especially when anxiety or depression are present. Antidepressants may reduce binge-purge cycles in bulimia. No medication directly treats anorexia, but medication can support overall care in some cases.
What if someone is not ready for treatment?
Feeling unsure about getting help is common. Motivational counseling, learning about health risks, and support from trusted friends or family can encourage treatment. When health is at risk or decision-making is impaired, more intensive or legally required care may sometimes be needed.
