Explanation
Core Causes of Anorexia nervosa
Anorexia nervosa is a serious eating disorder characterised by restriction of energy intake leading to significantly low body weight, intense fear of weight gain, and distorted body image. It has the highest mortality rate of any mental health condition, due to both medical complications and suicide. Medical complications affect the cardiovascular, endocrine, gastrointestinal, musculoskeletal, and neurological systems. Early intervention and specialised eating disorder treatment significantly improve outcomes.

People commonly experience
Anorexia nervosa shows up differently for everyone. Browse by how it tends to be felt — these are common experiences, not a checklist or a diagnosis.
In the body5 common experiences
- Anorexia nervosa is experienced as a deeply complex interplay of psychological, emotional, and physical symptoms
- Many people describe a pervasive preoccupation with food, weight, and body shape that dominates conscious thought
- Physical effects — extreme fatigue, cold intolerance, hair loss, dizziness, and a cessation of menstruation — often feel secondary to the psychological need to maintain restriction
- Many people describe profound fear around eating or weight gain
- The condition is among the most medically serious of all mental health conditions, and early intervention significantly improves outcomes
In daily life1 common experience
- The restriction of food is experienced not as suffering but, in the early stages at least, as control and achievement — a source of identity and safety
Common experiences people describe — not a diagnostic checklist.
Why it happens
Possible causes & risk factors
Anorexia nervosa usually comes from a mix of factors rather than a single cause. These are common contributors — not certainties.
Biology & temperament
Genetic factors and brain chemistry differences may raise susceptibility to anorexia nervosa.
Stress & life events
Perfectionism, trauma, and a need for control are commonly linked to onset of restrictive eating.
Health & substances
A history of anxiety, early dieting, or other mental health conditions may increase overall risk.
Sleep & lifestyle
Poor sleep may worsen mood regulation and reinforce rigid thinking patterns around food and weight.
What happens in the body
How this may affect the body
Anorexia nervosa can involve several of the body’s systems. These are common patterns researchers describe — how they show up varies from person to person.
Nervous System
neurologicalSevere caloric restriction may reduce brain volume and alter neurotransmitter activity, contributing to distorted body image, rigid thinking, and heightened anxiety around food.
Endocrine System
hormonalProlonged energy deficit can suppress reproductive hormones and disrupt thyroid and cortisol regulation, leading to amenorrhea, low bone turnover, and metabolic slowing.
Cardiovascular System
physiologicalMalnutrition may cause the heart muscle to weaken and electrolyte imbalances to develop, increasing the risk of bradycardia, low blood pressure, and dangerous arrhythmias.
Musculoskeletal System
musculoskeletalChronically low estrogen and inadequate calcium intake may reduce bone mineral density over time, raising the likelihood of stress fractures and early-onset osteoporosis.
Process
Diagnosis & Assessment
- Clinical interview and historyA clinician explores eating patterns, food restriction behaviors, fear of weight gain, and body image concerns, alongside any history of dieting, trauma, or anxiety.
- Physical examination and vitalsBody weight, BMI, heart rate, blood pressure, and signs of malnutrition such as lanugo, hair thinning, or cold extremities are assessed to gauge medical severity.
- Laboratory and cardiac screeningBlood tests check electrolytes, glucose, and organ function; an ECG may be conducted to detect arrhythmias associated with prolonged nutritional restriction.
- Psychological and risk assessmentStandardized tools such as the EDE-Q may be used to evaluate eating disorder cognitions, mood, and suicide or self-harm risk, informing the level of care required.
Management
Treatment & Management
Specialist eating disorder therapy
Evidence-based psychological therapies such as CBT-E and family-based treatment (FBT) are the primary recommended approaches for anorexia nervosa and are central to most treatment plans.
Medical monitoring and stabilization
A physician may oversee physical health including cardiac function, electrolyte levels, and bone density, as anorexia nervosa carries significant medical risk requiring clinical oversight.
Nutritional rehabilitation
Working with a registered dietitian experienced in eating disorders may support gradual, structured refeeding in a way that addresses both physical restoration and fear around food.
Psychiatric medication review
A psychiatrist may discuss whether medications such as atypical antipsychotics or antidepressants are appropriate to support co-occurring anxiety, depression, or obsessive symptoms alongside therapy.
Body-based and somatic approaches
Some people find that gentle somatic therapies or trauma-informed bodywork, used only under clinical guidance, may support reconnection with the body as part of a broader treatment program.
Self-Care
Lifestyle & Self-Care
Prioritize structured meal support
Working with a dietitian or care team to establish regular, supported eating times may help reduce anxiety around meals and build consistency in nutritional rehabilitation.
Explore gentle body awareness practices
Some people find that slow, non-exercise-focused practices such as restorative yoga or breathwork support a gradual reconnection with the body, only when cleared by a clinical team.
Build a recovery-oriented environment
Reducing exposure to diet culture content, weight-focused media, and triggering social situations may support a sense of safety during the recovery process.
Engage in evidence-based therapeutic work
Specialist therapies such as family-based treatment or cognitive approaches, delivered by trained eating disorder clinicians, are central to recovery and not optional additions.
Cultivate non-food sources of identity
Some practitioners suggest gently exploring creative outlets, values-based activities, or social connection to help expand a sense of self beyond food, weight, and control.
The Evidence
Evidence context
What research and clinical practice tell us about anorexia nervosa, its risks, and the approaches with the strongest support.
Overall pictureStrong evidence base
A serious condition with well-established, specialised care pathways
Research consistently indicates that anorexia nervosa carries one of the highest mortality rates among mental health conditions, and it requires specialist-led care. Evidence strongly supports early intervention, medical stabilisation, and structured psychological treatment as the foundation of recovery.
What the evidence supportsSpecialised psychological and nutritional approaches have the strongest research backing.
Family-based treatment (Maudsley approach) has the strongest evidence for adolescents. For adults, CBT-E and Specialist Supportive Clinical Management are well-supported. Nutritional rehabilitation is fundamental across all age groups. Complementary approaches such as yoga and mindfulness show early promise as adjuncts but are not substitutes for specialist-led care.
When to seek urgent helpCertain physical signs indicate a medical emergency requiring immediate attention.
Seek urgent medical care for rapid or severe weight loss, fainting, chest pain, irregular heartbeat, cold or blue extremities, or swelling in the legs or face. These may indicate serious cardiac or metabolic complications. Do not wait for a scheduled appointment if these symptoms are present.
Approaches to avoidSeveral common wellness practices carry significant risk in the context of anorexia nervosa.
Fasting, restrictive diets, weight loss programmes, and high-intensity exercise are contraindicated and can cause serious harm. Diet culture messaging — including content framing restriction as health — may reinforce harmful patterns. Any wellness or complementary approach should be reviewed by a qualified eating disorder clinician before use.
The role of specialist careMedical stabilisation comes first — psychological and complementary support follows within a supervised framework.
Anorexia nervosa affects multiple body systems including the heart, bones, hormones, and brain. Medical assessment and stabilisation are the first priority. Psychological treatment, nutritional support, and any adjunct approaches should be coordinated through a specialist eating disorder team rather than pursued independently.
Complementary approaches as adjunctsSome complementary practices may support recovery when used alongside — not instead of — specialist care.
Practices such as yoga, mindfulness, somatic therapy, and art therapy are used in some eating disorder programmes to support body awareness, emotional regulation, and self-compassion. Evidence is emerging rather than definitive. These approaches are most appropriate when introduced under clinical supervision as part of a broader care plan.
Finding the right supportEating disorder care is specialised — general mental health or wellness services may not be sufficient.
If you or someone you know is affected, contact a GP, eating disorder service, or crisis line as a first step. Early intervention significantly improves outcomes. Specialist eating disorder teams — not general wellness providers — are best placed to coordinate safe, effective care. Gyfts does not replace professional assessment or specialist care.

FAQ
Common questions
What makes anorexia nervosa different from other eating disorders?
Anorexia involves persistent restriction driven by intense fear of weight gain and a distorted sense of body size. Unlike other eating disorders, malnutrition is central and creates serious medical risk alongside the psychological experience.
Can complementary or holistic approaches play a role in recovery?
Some people find that practices like gentle movement, mindfulness, or creative therapies support emotional wellbeing alongside specialist care. These should never replace medical or psychological treatment and must be guided by a treatment team.
Why is general therapy not enough for anorexia nervosa?
Anorexia involves medical as well as psychological complexity. Specialist eating disorder services coordinate nutritional, medical, and therapeutic care together, which general therapy alone is not equipped to provide.
When should someone seek urgent medical attention for anorexia?
Seek urgent evaluation if there is fainting, chest pain, cold or discolored extremities, swelling, or rapid weight loss. These may indicate serious physical complications that require immediate medical care.
Is full recovery from anorexia nervosa possible?
Many people do achieve full recovery, particularly with early, specialist intervention. Recovery is often a gradual process involving medical, nutritional, and psychological support, and outcomes are meaningfully better with timely care.
