AI Summary Overview
What is Anorexia Nervosa?
Anorexia nervosa is an eating disorder in which a person deliberately restricts food intake to maintain a body weight that is significantly below the healthy range for their age and height. The condition is characterised by an overwhelming fear of weight gain and persistent behaviours aimed at preventing weight gain, even when the individual is underweight.
Since it is a psychological disorder, anorexia nervosa can have serious physical and emotional consequences if left untreated.
Types of Anorexia Nervosa
Two types of anorexia nervosa are recognised, which include:
-
Restrictive Type: The person loses weight mostly through starvation, fasting, or excessive exercise, with no incidents of binge eating.
-
Binge-Eating/Purging Type: Cases involve episodes of binge eating followed by purging behaviours, including self-induced vomiting, laxative misuse, and excessive exercise.
How Common is Anorexia Nervosa in India?
Anorexia nervosa is a growing concern in India. The prevalence of anorexia nervosa is an estimated 22.3 per 100,000, with 10 per 100,000 for males and 37.2 per 100,000 for females. The condition is more commonly reported in females, although it can affect any gender.
Growing concerns about body image, social media influence, and changing lifestyle patterns have contributed to the rise in eating disorders. Many cases go under-reported due to a lack of awareness and limited access to healthcare facilities in rural India.
What are the Symptoms of Anorexia Nervosa?
The symptoms of anorexia nervosa usually develop gradually and may worsen without treatment. Early symptoms often involve changes in eating behaviour and body image, while prolonged malnutrition can lead to serious physical and psychological complications.
Here are the early and advanced symptoms of anorexia nervosa:

What are the Causes and Risk Factors of Anorexia Nervosa?
The development of anorexia nervosa is caused by biological, psychological, and environmental factors. Some of the causes include:
-
Biological Risk Factors
- Genetics: Those who have a history of disorders such as eating disorders, anxiety, depression, and OCD are likely to develop anorexia nervosa.
- Imbalance of Chemicals: Some neurochemical imbalances in certain brain chemicals that regulate reward and appetite are linked to this condition.
-
Psychological Risk Factors
- Tendency Towards Perfectionism: Perfectionists are susceptible to developing anorexia nervosa.
- Poor Body Image and Low Self-Esteem: Having poor body image and low self-respect could be an element predisposing someone to eating disorders.
- Other Psychological Disorders: If someone has another psychological disorder, they have a higher risk of developing anorexia nervosa.
-
Environmental Risk Factors
- Social Media Influence: Unreasonable body expectations on social media can leave a person discontented with their body.
- Culture: Societal pressure to remain thin is another factor that increases a person's likelihood to developing anorexia.
- Body Weight Bullying/Criticism: Criticising someone based on their weight could lead to unhealthy behaviours regarding eating.
Progression of Anorexia Nervosa
There are no distinct clinical stages of anorexia nervosa. Rather, it progresses through many phases, depending on the degree of food restriction, nutritional state, responsiveness to treatment and the presence of problems. The progression of anorexia nervosa is as follows:
| Disease Progression Phase | Features |
| Early Restrictive Behaviour | Persistent dieting, calorie restriction, excessive exercise, fear of weight gain, and increasing dissatisfaction with body image begin to affect eating habits. |
| Established Eating Disorder | Ongoing food restriction results in noticeable weight loss, nutritional deficiencies, menstrual irregularities, fatigue, and increasing emotional distress. |
| Severe Illness | Severe malnutrition may cause cardiovascular complications, electrolyte imbalances, hormonal disturbances, reduced bone density, impaired immunity, and organ dysfunction. |
| Recovery and Relapse | Nutritional rehabilitation and psychological treatment help restore physical health and eating behaviours. However, relapse may occur without long-term follow-up and continued mental health support. |
Diseases Similar to Anorexia Nervosa
Although anorexia nervosa, bulimia nervosa, and Avoidant/Restrictive Food Intake Disorder (ARFID) are all eating disorders, they differ in their underlying behaviour, physical effects, and treatment approach. Understanding these differences helps ensure an accurate diagnosis and appropriate management.
Anorexia Nervosa vs Bulimia Nervosa vs Avoidant/Restrictive Food Intake Disorder (ARFID)
| Feature | Anorexia Nervosa | Bulimia Nervosa | Avoidant/Restrictive Food Intake Disorder (ARFID) |
| How it Happens | Severe restriction of food intake due to an intense fear of weight gain and distorted body image. | Recurrent episodes of binge eating followed by compensatory behaviours such as vomiting, fasting, or excessive exercise. | Restrictive eating caused by sensory sensitivity, fear of choking, or lack of interest in eating, rather than concerns about body weight. |
| Body Weight | Usually significantly below the healthy range. | Often remains within or near the normal weight range. | May be underweight, normal weight, or overweight depending on nutritional intake. |
| Associated Symptoms | Severe weight loss, fatigue, menstrual irregularities, bradycardia, anxiety, and depression. | Tooth enamel erosion, swollen salivary glands, electrolyte imbalance, and gastrointestinal problems. | Poor growth, nutritional deficiencies, weight loss, and dependence on nutritional supplements in severe cases. |
| Severity | High risk of life-threatening medical complications if untreated. | Can cause serious metabolic and gastrointestinal complications if recurrent. | Severity varies depending on the degree of nutritional deficiency and weight loss. |
| Can It Be Reversed? | Recovery is possible with nutritional rehabilitation, psychotherapy, and long-term follow-up, although relapse may occur. | Many people recover with psychological therapy and nutritional support. | Many patients improve with behavioural therapy, nutritional support, and treatment of underlying anxiety or sensory issues. |
What are the Complications of Anorexia Nervosa?
Untreated anorexia nervosa can cause the following complications:
-
Cardiovascular System
- Bradycardia and hypotension are among the most frequent symptoms displayed by patients with anorexia.
- Due to a lack of nutrients, heart muscle cells shrink, causing the heart to work more slowly. This increases the risk of arrhythmia and sudden death.
- Cardiac issues are observed in a third of all deaths from anorexia, mainly because of sudden cardiac death.
-
Other Complications
- Hormonal imbalances, including menstrual irregularities
- Digestive problems such as constipation and bloating
- Weakened immune system and increased susceptibility to infections
- Depression, anxiety, and other mental health disorders
- Fertility and reproductive health issues
- In severe cases, organ failure and life-threatening complications
Anorexia Nervosa in Pregnancy
Anorexia nervosa during pregnancy can affect the health of both the mother and the baby. Inadequate nutrition may increase the risk of anaemia, fatigue, and pregnancy complications. It can also lead to poor fetal growth, low birth weight, and premature delivery.
Some women may find it difficult to cope with the normal weight changes that occur during pregnancy. Early diagnosis, nutritional support, and mental health care are important for a healthy pregnancy outcome.
When Should I See My Healthcare Provider?
Consult your doctor immediately in case of:
-
Unexplained weight loss
-
Persistent dieting
-
An intense or overwhelming fear of gaining weight
-
Not having a period
-
Feeling dizzy or fainting
-
Excessive physical activity after meals
-
Food obsession or preoccupation with appearance
-
Symptoms of malnutrition
How is Anorexia Nervosa Diagnosed?
There is no single test for anorexia nervosa. A doctor will typically conduct the following to diagnose anorexia nervosa:
| Test Name | Detects | Purpose |
| BMI | Low value compared to the normal level (18.5-24.9 kg/m²) | Measurement of weight status |
| Complete Blood Count | Anemia and abnormal blood levels | Assessment of nutritional deficiency |
| Electrolyte Profile | Electrolyte imbalance | Detection of any possible medical complication |
| Thyroid Function Test | Hormonal irregularity | Differential diagnosis of the cause of weight loss |
| ECG | Arrhythmia or bradycardia | Evaluation of cardiac-related complications |
| Psychological Assessment | Indicative of anorexia nervosa | Confirmation of the diagnosis |
Note: The diagnosis of anorexia nervosa uses physical exam, testing, and psychological evaluation techniques. There is no laboratory test to confirm the illness.
How is Anorexia Nervosa Treated/Managed?
Anorexia nervosa can be managed by attaining a healthy body weight, addressing nutritional inadequacies, and addressing the psychological elements. Treatment strategies include:
-
Nutritional Therapy: This therapy focuses on adopting a healthy nutritional regimen that will lead to a healthy body weight.
-
Psychological Therapy: Various types of therapy help deal with problems like body image issues and fears associated with eating disorders.
-
Family Therapy: Family therapy is effective in handling cases involving adolescents and children.
-
Medical Examination: An examination is performed to determine the physical problems caused by the condition, especially those affecting the heart, bones, and other hormone-related issues.
-
Hospitalisation: In severe cases, hospitalisation may be required for treatment.
Medicines Used to Treat Anorexia Nervosa
Medicines are not the main therapy for anorexia nervosa. Nutritional rehabilitation and psychotherapy continue to be the mainstay of treatment. Medications may be used to help manage associated psychological problems, improve weight gain in select patients or treat medical concerns.
Some common medicines used in the treatment of anorexia nervosa include:
-
Olanzapine (Atypical Antipsychotic): May help reduce obsessive thoughts about body weight and food while supporting gradual weight gain in selected patients with severe anorexia nervosa.
-
Fluoxetine (Selective Serotonin Reuptake Inhibitor - SSRI): May be prescribed after nutritional recovery to manage coexisting depression, anxiety, or obsessive-compulsive disorder symptoms and reduce the risk of relapse.
-
Sertraline or Escitalopram (SSRIs): Used to treat associated anxiety disorders or depression once adequate nutritional status has been restored.
-
Calcium and Vitamin D Supplements: Help improve bone health and reduce the risk of osteoporosis and fractures caused by prolonged malnutrition.
-
Multivitamin and Mineral Supplements: Correct vitamin and mineral deficiencies that commonly occur due to prolonged inadequate food intake.
Note: Medicines alone cannot cure anorexia nervosa. They should only be used under the supervision of a qualified psychiatrist or physician as part of a comprehensive treatment plan that includes nutritional rehabilitation and psychological therapy.
Living with Anorexia Nervosa in India: Daily Challenges, Caregiving and Expenses
Anorexia nervosa is generally a long-term illness requiring medical treatment, dietary rehabilitation and psychosocial support. Recovery is usually gradual and continuous follow-up reduces the chance of relapse and improves physical and mental health.
Hereis how living with anorexia nervosa can affect your daily life:
-
Daily Challenges
- Maintaining Adequate Nutrition: Fear of weight gain and limited eating practices may affect the ability to follow a balanced meal plan and delay nutritional recovery.
- Managing Body Image Concerns: You continue to experience distorted body image and anxiety about weight even after beginning treatment.
- Daily Activities: During rehabilitation, you may feel tired, have poor focus, and experience physical weakness that interferes with school, work, and social contact.
- Coping with Relapse Risk: Stressful life events, social pressure, or untreated mental health conditions may trigger relapse, making long-term psychological support important.
-
Caregiving and Patient Safety
- Supporting Treatment Adherence: Family members and carers should encourage regular meals, medicines, psychotherapy sessions and follow-up visits.
- Monitoring for Warning Signs: Rapid weight loss, fainting, dehydration, chest pain, suicidal thoughts, or refusal to eat require immediate medical attention.
- Providing Emotional Support: A supportive and non-judgemental environment helps reduce shame, improves treatment adherence, and encourages recovery.
- Preventing Medical Complications: Regularly monitoring body weight, cardiac function, electrolyte balance, and nutritional status may help to detect complications early.
-
Expenses
- Psychiatric and Psychological Care: Long-term consultations with psychiatrists and psychologists are often required throughout treatment and recovery.
- Nutritional Counselling and Monitoring: Regular visits to a registered dietitian, laboratory investigations, and nutritional supplements contribute to overall treatment costs.
- Hospitalisation for Severe Illness: If you have critical malnutrition, medical instability or refeeding syndrome, you may require in-patient treatment, which can increase medical expenses.
- Long-term Follow-up: Ongoing psychotherapy, nutritional rehabilitation, and periodic medical reviews remain essential to maintain recovery and prevent relapse.
What is the Prognosis for Anorexia Nervosa?
The prognosis for anorexia nervosa depends on when treatment starts and the extent to which it has impacted the person. The long-term prognosis is usually favourable where patients have mostly succeeded in recovering completely through medication, nutrition, and psychological intervention. However, it takes time for a patient to recover, since relapses might occur.
How to Prevent Anorexia Nervosa?
The following measures can help in reducing the risk of becoming affected by anorexia nervosa:
-
Promoting positive body image
-
Maintaining good eating practices
-
Dealing with anxiety and depression
-
Encouraging open dialogue about mental health
-
Seeking professional advice when required
Anorexia Nervosa Treatment Cost in India

| Bone Density (DEXA) Scan | ₹2,000 - ₹10,000 |
| In-patient Nutritional Rehabilitation/Hospitalisation | ₹25,000 - ₹1,50,000+ |
Disclaimer: The above costs are approximate and may vary depending on the city, hospital, disease severity, duration of treatment, and investigations. Hospitalisation and management of severe medical complications can substantially increase the overall treatment cost.
Does Health Insurance Cover Anorexia Nervosa?
Yes. Most health insurance plans in India offer coverage for anorexia nervosa, as per the Mental Healthcare Act of 2017 and the directions of IRDAI. Coverage includes in-patient hospitalisation, counselling, diagnostic tests, medications, nutrition treatment, and psychotherapy according to the policy terms and conditions. You can have your outpatient consultations and therapies covered if your health insurance for mental health policy comes with an OPD benefit.
Although anorexia nervosa is not included in critical illness insurance plans, its complications, like heart attacks, acute kidney failure, and sepsis, are sometimes included. This allows you to get a lump sum benefit to pay for the complications resulting from anorexia nervosa.
However, there can be a waiting period of up to 2 years if your anorexia nervosa is a pre-existing condition, i.e., it was already diagnosed before purchasing the health plan. However, the exact terms and conditions may vary depending on the insurer and plan.
How Much Health Insurance Coverage is Needed for Anorexia Nervosa Treatment?
Taking into account the treatment period for anorexia nervosa, in-patient treatment might extend from weeks to even months, in addition to the costs of the psychiatrist's service, dietitian's fee, lab tests, and medicines. These expenses vary depending on the location, severity of the condition, and the treatment procedures required for anorexia nervosa.
Therefore, a health insurance policy with a sum insured of ₹10 to ₹15 lakh is sufficient for anorexia nervosa, given the length of stay in the hospital, especially when we consider tertiary care in a private hospital.
Make sure to read policy documents carefully and review the inclusions and exclusions to choose a plan that suits your health requirements.
