Anorexia nervosa
Also known as: anorexia nervosa, restricting-type anorexia nervosa, binge-eating and purging-type anorexia nervosa, atypical anorexia nervosa, restrictive eating disorder, eating disorder with severe dietary restriction
Anorexia nervosa is a serious and potentially life-threatening eating disorder characterised by persistent restriction of energy intake, intense fear of weight gain or behaviours that interfere with weight restoration, and disturbance in body-image experience or recognition of illness severity. Some people binge, vomit, misuse laxatives, diuretics or medicines, or exercise compulsively. Atypical anorexia nervosa can cause equally serious medical and psychological complications even when body weight is within or above a statistically expected range. Eating disorders can affect people of every gender, age, culture and body size and are not a lifestyle choice. Complications may involve the heart, circulation, electrolytes, kidneys, gastrointestinal tract, endocrine and reproductive systems, bones, muscles, brain, blood and immune system. Assessment should include eating-disorder symptoms, rate of weight change, physical observations, cardiovascular status, blood tests, electrocardiography when indicated, mental-health risk, exercise, purging, medicines and social circumstances. Treatment commonly involves an eating-disorder-informed multidisciplinary team, nutritional rehabilitation, psychological therapy, medical monitoring and family or carer involvement when appropriate. Children and adolescents require prompt specialist care because malnutrition can impair growth and pubertal development. Refeeding must be medically managed in patients at risk because rapid nutritional change can cause dangerous fluid and electrolyte shifts. TCM patterns may include Spleen Qi deficiency, Spleen and Stomach Qi-Yin deficiency, Heart-Spleen deficiency, Liver Qi stagnation attacking the Spleen, Stomach Yin deficiency, Spleen-Kidney Yang deficiency and Qi-Blood deficiency. Acupuncture and Chinese herbal medicine must remain secondary supportive interventions and must never replace nutritional rehabilitation, psychotherapy, medical monitoring, safeguarding or hospital treatment.

- •Attend recommended blood tests, electrocardiograms, bone-health assessment and physical reviews.
- •Discuss menstrual, hormonal, fertility, sexual-health and pubertal changes with the treating team.
- •Amenorrhoea or reduced testosterone should not be managed only with hormones while malnutrition continues.
- •Avoid alcohol and recreational drugs when medically compromised or taking psychiatric medicines.

- •Call Lifeline on 13 11 14 or emergency services on 000 when immediate suicide or medical danger is present.
- •Recovery is possible, but improvement in appearance or weight alone does not confirm psychological or medical recovery.
Cautions & Contraindications
- •Do not treat anorexia nervosa solely with acupuncture, herbs, supplements, coaching or dietary advice.
- •Do not delay hospital assessment when medical instability or severe psychiatric risk is present.
- •Do not use weight, body mass index or appearance alone to judge illness severity.
- •Do not prescribe weight loss, fasting, detoxification, cleansing, elimination diets or appetite suppression.
- •Do not validate eating-disorder rules by describing required foods as inflammatory, toxic, Damp-forming or energetically harmful.
- •Do not recommend excessive exercise or movement as treatment for Qi stagnation.
- •Do not perform bloodletting, wet cupping or strongly depleting treatment.
- •Do not advise stopping psychiatric medicines, nutritional supplements or prescribed meal plans.
- •Do not begin high-dose carbohydrate, electrolyte or vitamin supplementation in a high-risk patient without medical oversight.
- •Do not treat oedema during refeeding as simple Dampness requiring diuresis.
- •Do not use diuretic or purgative herbs in dehydration, electrolyte disturbance or laxative misuse.
- •Do not interpret food refusal, compulsions or body-image disturbance as lack of willpower.
- •Do not use moxibustion instead of medical treatment for hypothermia.
- •Fù Zǐ is inappropriate without specialist processing and prescribing because of cardiotoxicity and neurotoxicity.
- •Má Huáng should generally be avoided because stimulant effects may worsen cardiovascular risk, anxiety and weight-loss behaviour.
- •Dà Huáng, Fān Xiè Yè, Bā Dòu and other purgatives are inappropriate in restrictive eating, dehydration or laxative misuse.
- •Gān Cǎo may worsen hypokalaemia, oedema, hypertension and medicine interactions.
- •Bàn Xià must be correctly processed and should not be used to normalise or facilitate self-induced vomiting.
- •Dāng Guī, Chuān Xiōng and other Blood-moving herbs require pregnancy and bleeding-risk review.
- •Screen all herbs for liver or kidney disease, electrolyte disturbance, pregnancy, allergies and psychiatric-medicine interactions.
- •Do not interpret worsening weakness, confusion, oedema, coldness or palpitations as a healing response.
When to reassess or seek care again
- •Coordinate reassessment cadence with the eating-disorder team; do not set an independent schedule.
- •Escalate immediately for cardiovascular instability, electrolyte symptoms, refeeding signs or suicidal risk between sessions.
- •Reassess suitability of adjunctive acupuncture at every visit while medical status is changing.
- •Life stressors, transitions, trauma anniversaries or loss.
- •Renewed exposure to weight-loss, fitness or pro-eating-disorder content.
- •Injury, illness or medicines that alter appetite or weight.
- •Pregnancy, postpartum period or peri-menopause.
- •Reduction of psychological or dietetic support without a relapse-prevention plan.
Weight or appearance alone does not confirm recovery. Continue coordinated multidisciplinary review even when the patient looks well.
Frequently Asked Questions
What is anorexia nervosa?+
Anorexia nervosa is a serious eating disorder involving restrictive intake, fear of weight gain or behaviours preventing weight restoration, and disturbed body-image experience or limited recognition of illness severity [4].
Is anorexia nervosa a choice?+
No. It is a complex mental illness requiring compassionate, evidence-based treatment [4].
Can anorexia occur at a normal or higher body weight?+
Yes. Atypical anorexia nervosa can cause severe malnutrition and medical instability even when body weight is not classified as low [4].
What symptoms require emergency care?+
Collapse, chest pain, fainting, severe weakness, seizures, confusion, significant dehydration, uncontrolled vomiting, severe electrolyte symptoms or suicidal risk require urgent care [4].
What is refeeding syndrome?+
Refeeding syndrome is a dangerous metabolic response that can occur when nutrition is restarted after severe restriction, causing electrolyte and fluid shifts that may affect the heart, lungs and nervous system [4].
How is anorexia nervosa treated?+
Treatment commonly combines medical monitoring, nutritional rehabilitation, psychological therapy and family or carer support when appropriate [4].
What TCM patterns may be considered?+
Patterns may include Spleen Qi deficiency, Stomach Yin deficiency, Heart-Spleen deficiency, Liver Qi stagnation attacking the Spleen, Spleen-Kidney Yang deficiency and Qi-Blood-Yin deficiency [7].
Can acupuncture cure anorexia nervosa?+
No. Acupuncture may be considered only as an adjunct for selected symptoms and must not replace specialist treatment [7].
Can herbs stimulate appetite safely?+
Herbs may cause adverse effects or interactions and cannot correct severe malnutrition. Any use must be coordinated with the eating-disorder treatment plan [7].
Should exercise continue during treatment?+
Exercise may need to be reduced or stopped when medical instability, compulsive exercise, injury or inadequate nutrition is present. The treatment team should guide safe activity [4].
