When to see a doctor
See a doctor urgently if:
- If you or someone you know is in immediate danger due to severe weight loss, fainting, chest pain, or thoughts of suicide – call your local emergency number right away.
Book a routine appointment if:
- If you are worried about your eating habits or body image and they are interfering with your daily life
- If you notice a loved one avoiding meals, losing weight rapidly, or expressing extreme fear of weight gain
- If you have tried to stop harmful eating behaviors but can’t do it alone
Diagnosis
A doctor or mental health professional will ask about your eating habits, thoughts, and feelings about food and body image. They may use questionnaires and check your physical health to rule out other causes.
Tests that may be done
- Physical exam including weight and height measurements
- Blood tests to check for nutritional deficiencies and electrolyte imbalances
- Heart function tests like an electrocardiogram (EKG) if needed
- Psychological assessment by a specialist
What to expect at your appointment
The diagnosis process is thorough but supportive. You will have time to share your story. The goal is to understand your symptoms and provide the right care. You may be referred to a specialist team that includes doctors, therapists, and dietitians.
Treatment
Treatment for eating disorders usually involves talking therapies, medical care, and nutritional support. The goal is to restore healthy eating habits, address underlying emotional issues, and prevent serious health problems.
Self-care at home
- Educate yourself about eating disorders from reliable sources like the NHS website
- Keep a food and mood diary to understand triggers
- Avoid weighing yourself too often
- Practice self-compassion and challenge negative thoughts about your body
- Find healthy ways to cope with stress, like walking, art, or talking to a friend
Medical treatments
Medical treatment is guided by a healthcare team. It may include psychological therapies such as cognitive behavioral therapy (CBT), family-based therapy (especially for young people), or interpersonal therapy. In some cases, medications may be offered to treat depression or anxiety that often occurs alongside eating disorders. Hospitalization may be needed if weight loss is severe or there are medical complications. Your doctor will discuss the best options for you.
When is surgery considered?
Surgery is not a treatment for eating disorders. However, in some cases of severe obesity that involves binge eating disorder, weight loss surgery may be considered after mental health treatment, but it is not a first-line treatment.
Living with this condition
Living with an eating disorder can be challenging, but with support, you can take steps toward recovery. Focus on building a routine that includes regular meals, support from others, and self-care activities.
Lifestyle tips
- Plan meals with a dietitian to ensure balanced nutrition
- Join a support group to connect with others who understand
- Limit exposure to social media or content that promotes unhealthy body standards
- Find activities you enjoy that are not focused on appearance or exercise
Diet and exercise
Work with a professional to develop a healthy eating plan that meets your needs. Exercise should be done for enjoyment and health, not as a way to control weight. Avoid excessive or compulsive exercise.
Mental health and emotional wellbeing
Eating disorders often go hand in hand with depression, anxiety, and low self-esteem. Therapy can help address these issues. It’s important to be patient with yourself – recovery takes time.
Prevention
While it may not always be possible to prevent eating disorders, promoting a healthy body image, avoiding dieting talk, and addressing mental health concerns early can reduce the risk.
Screening programmes
There is no routine screening test for eating disorders, but doctors may screen if they notice warning signs. You can also use self-screening tools online from reputable organizations to decide if you need help.
Complications
If left untreated
- Severe malnutrition and organ damage
- Heart problems like irregular rhythm or heart failure
- Bone density loss (osteoporosis)
- Fertility problems
- Increased risk of death from medical complications or suicide
Long-term outlook
With early treatment and support, many people recover from eating disorders. Recovery is a journey, and relapses can happen, but with professional help and a strong support system, you can lead a full and healthy life. Never lose hope – you are not alone.
