what are the causes of anorexia

Anorexia nervosa does not have a single cause; it develops from a mix of biological, psychological, and social factors, and it is never the person’s fault.

What Are the Causes of Anorexia?

Anorexia nervosa is a serious mental illness, not a lifestyle choice or a diet gone too far.

Understanding the causes can help with early support and reduce shame.

1. Biological and Genetic Causes

Research shows that biology can make some people more vulnerable to anorexia.

  • Family history of eating disorders or other mental health conditions (like anxiety, depression, OCD) increases risk.
  • Genetic factors: twin and family studies suggest anorexia has a strong heritable component (often estimated at roughly half or more of the risk).
  • Brain differences: how the brain processes reward, anxiety, and hunger can be altered, making it easier to ignore hunger and feel “relief” from restricting food.
  • Puberty and hormones: rapid body changes, hormonal shifts, and growth spurts can trigger body-image distress and eating problems in genetically vulnerable people.

Example: A teen with a family history of anxiety and perfectionism hits puberty, feels suddenly uncomfortable in their changing body, and discovers that restricting food temporarily eases their anxiety. Over time this pattern can harden into anorexia.

2. Psychological and Personality Factors

Certain personality traits and emotional patterns commonly appear in people with anorexia.

  • Perfectionism and rule-following: needing to “do everything perfectly,” including eating and weight control.
  • High anxiety and fear of losing control; food restriction can feel like one of the only controllable areas of life.
  • Obsessive or rigid thinking: strict rules around “good” and “bad” foods or numbers on the scale.
  • Low self-esteem and negative body image: feeling “never good enough” or constantly criticizing one’s body.
  • Difficulty expressing or managing emotions; using food and weight as a way to cope with anger, sadness, fear, or shame.

Many people describe anorexia as becoming a “voice” in their head that promises safety and control but actually makes them more isolated and unwell.

3. Trauma and Stressful Life Events

Trauma and major stressors do not “cause” anorexia by themselves, but they can be powerful triggers in someone who is already vulnerable.

  • Emotional, physical, or sexual abuse.
  • Bullying or shaming about weight, shape, or appearance (from peers, family, coaches, or online).
  • Big life changes: changing schools, relationship breakups, moving away from home, losses or illness in the family.
  • Experiences of being criticized or compared with siblings or peers.

In these situations, controlling food and weight can become a coping strategy to numb feelings or create a sense of order when life feels chaotic.

4. Social, Cultural, and Online Influences

Modern culture plays a big role in shaping body ideals and weight stigma, which can fuel eating disorders.

  • Thin or “fit” body ideals promoted in media, social media, fashion, fitness culture, and even health campaigns.
  • Praise for weight loss and “discipline,” even when the behaviors are unhealthy.
  • Weight stigma and fatphobia: fear of being judged, excluded, or bullied for body size.
  • Diet culture: constant talk of “good” vs. “bad” foods, detoxes, and restrictive plans that normalize extreme control over eating.
  • Activities that focus heavily on weight or appearance (e.g., gymnastics, ballet, modeling, figure skating, wrestling, endurance sports).

Forum-style angle: what people say online

“It started as ‘just trying to be healthier’ after seeing fitness posts on my feed. Compliments about my weight loss made it so much harder to stop.”

In recent years, forums and social platforms sometimes host harmful content that glamorizes extreme thinness or “pro-ana” behavior, though many platforms now try to moderate this. At the same time, there is a growing counter- movement around body positivity, weight-neutral health, and recovery communities that can be protective.

5. Early Dieting and “Innocent” Weight Loss

Anorexia often begins with what looks like a normal diet or lifestyle change.

  • Starting a diet after a comment about weight from a friend, family member, or doctor.
  • Trying to “eat clean” or “get fit” and gradually cutting more and more foods.
  • Getting praised for losing a few kilos or pounds and then feeling pressured to keep going.
  • Using exercise more and more, not just for health but as a way to “earn” food or compensate for eating.

For someone with the right combination of genes, personality traits, and stressors, these behaviors can spiral into severe restriction and obsessive thinking around food and weight.

6. Not “About Food” – What Anorexia Can Really Be About

Many clinicians emphasize that anorexia is rarely truly about wanting to be thin; instead, weight and food become a language for deeper struggles.

Common underlying themes include:

  • A need for control when other parts of life feel unpredictable.
  • Fear of growing up, sexuality, or adult responsibilities (staying extremely thin can sometimes feel like staying “small” or “childlike”).
  • A way to numb emotions, trauma memories, or shame.
  • A way to communicate distress when it feels impossible to say “I’m not okay” out loud.

8. Latest angles and trending discussion

In recent years, conversations about anorexia have shifted to include:

  • Critiques of BMI “report cards” and school weigh-ins, which may increase body shame and disordered eating.
  • Increased awareness of anorexia in boys, men, nonbinary people, and older adults, not just thin young women.
  • The impact of filters and edited images in social media feeds on body dissatisfaction.
  • “Health at Every Size” and body‑positivity movements, which try to reduce weight stigma and may help protect some people from disordered eating.

Online forums often have mixed content: some users share powerful recovery stories, others post about urges to restrict, and many discuss feeling invisible because they “don’t look sick enough” to be taken seriously. This underlines that anorexia is about health and suffering, not just appearance.

9. If You’re Worried About Yourself or Someone Else

Anorexia can be life-threatening, but it is treatable, and many people recover with the right support.

  • Reach out to a trusted person (friend, family member, teacher, doctor, therapist) and describe what’s going on as honestly as you can.
  • Professional help from specialists in eating disorders (therapists, dietitians, doctors) is important; self‑help alone is usually not enough.
  • Early intervention is linked with better outcomes, less physical damage, and a smoother recovery.

If at any point there are signs of medical danger (fainting, chest pain, extremely rapid weight loss, suicidal thoughts), urgent or emergency medical care is needed. Bottom note: Information gathered from public forums or data available on the internet and portrayed here.
