Eating Disorders: Signs, Causes, and When to Seek Help
Eating disorders are not a character flaw or a choice. They are serious mental health conditions with medical consequences. Anorexia has one of the highest mortality rates among psychiatric disorders. Yet most people with these conditions go years without help — due to shame, misunderstanding, or the belief that "it's not that serious." This article is written without judgement: its aim is to help recognise the problem and take the first step towards help.
Types of eating disorders
Eating disorders (EDs) are a group of conditions in which the relationship with food, weight, and the body becomes a source of suffering and impairs quality of life. The main types:
- Anorexia nervosa — restriction of food intake, fear of gaining weight, distorted perception of one's body. The person sees themselves as "fat" despite an objectively normal or low weight.
- Bulimia nervosa — cycles of binge eating followed by "purging" (vomiting, laxatives, excessive exercise). Weight may be normal, which is why bulimia often goes unnoticed.
- Binge eating disorder (BED) — repeated episodes of binge eating without purging, accompanied by a sense of loss of control and shame. Often associated with obesity, but not always.
- Orthorexia — a pathological preoccupation with "clean" or "correct" eating that disrupts social life and causes anxiety at any deviation from the rules.
- Avoidant/restrictive food intake disorder (ARFID) — extreme food selectivity not related to body image concerns, often seen in children and adolescents.
EDs frequently co-occur with other conditions: depression, anxiety disorders, obsessive-compulsive disorder, and trauma.
Anorexia: signs that those close to the person notice
A person with anorexia typically does not see themselves as ill. This is why those around them often notice the problem first. What to look for:
- Severe restriction of food. The person eliminates entire food groups, finds reasons not to eat, eats very small portions, moves food around the plate without eating it.
- Preoccupation with food and weight. Constant calorie counting, talk about "bad" foods, excessive scrutiny of ingredient labels.
- Distorted body image. The person believes they are "fat" despite an obviously low weight. They do not accept feedback to the contrary.
- Physical signs. Significant weight loss; hair loss; constant feeling of cold; loss of periods in women; weakness and dizziness; fine downy hair on the body (lanugo) — the body's response to heat loss.
- Social withdrawal. Refusing shared meals, avoiding situations involving food.
- Compulsive exercise. Exercising despite fatigue, illness, or feeling unwell; anxiety when a workout is missed.
Anorexia is life-threatening. It causes heart rhythm disturbances, osteoporosis, kidney failure, and hormonal disruption. A BMI below 15–16 kg/m² typically requires hospitalisation.
Bulimia: the hidden disorder
Bulimia is harder to notice from the outside than anorexia: the person's weight may be normal or even above normal. The bulimia cycle looks like this: building tension — a binge episode (eating a large amount of food in a short time, feeling out of control) — shame and guilt — "purging" (vomiting, laxatives, diuretics, fasting, exhausting exercise) — temporary relief — tension builds again.
Signs that may be noticed:
- large amounts of food disappearing;
- frequent trips to the bathroom after meals;
- calluses on the knuckles (from inducing vomiting);
- swollen cheeks (enlarged salivary glands);
- erosion of tooth enamel (from stomach acid);
- sharp mood swings, especially around food.
Bulimia causes serious physical consequences: electrolyte imbalances (hypokalaemia — low potassium) that can lead to heart rhythm disturbances; damage to the oesophagus and teeth; bowel problems.
Binge eating disorder and emotional hunger
Binge eating disorder is the most common eating disorder. It differs from ordinary "overeating at a party": it involves repeated episodes (at least once a week for 3 months) in which the person eats rapidly, until uncomfortably full, without physical hunger, and feels shame and self-disgust afterwards.
A key concept is emotional hunger — eating in response to emotions (anxiety, boredom, loneliness, stress) rather than physical hunger. How to tell them apart:
- Physical hunger builds gradually, is tolerable, goes away after eating, and doesn't demand a specific food.
- Emotional hunger comes on suddenly, craves a specific food (usually sweet or fatty), doesn't go away when full, and is accompanied by guilt.
Binge eating disorder is often associated with obesity, but not always. It also frequently co-occurs with depression and anxiety disorders. Dieting without psychological work in BED typically doesn't work and can make the problem worse.
When to seek professional help
Eating disorders respond to treatment. But overcoming them alone is extremely difficult — especially anorexia and bulimia. It's worth seeking help if:
- thoughts about food, weight, and the body take up most of the day;
- the relationship with food causes suffering, shame, or anxiety;
- eating-related behaviour is disrupting social life, work, or study;
- there are physical symptoms (weight loss, loss of periods, weakness, dental problems);
- people close to you have expressed concern.
Who to see:
- A psychotherapist or psychologist experienced in EDs — the cornerstone of treatment. Cognitive-behavioural therapy (CBT) has shown the greatest effectiveness for bulimia and BED. Specialised therapies (FBT, CBT-E) are used for anorexia.
- A psychiatrist — when medication is needed (antidepressants for bulimia and BED, treatment of co-occurring conditions).
- A dietitian experienced in EDs — to normalise eating without restrictive dieting.
- A GP or paediatrician — to assess physical consequences and arrange hospitalisation if needed.

Frequently asked questions
How can I help a loved one with an eating disorder?
Don't comment on their appearance or weight — positively or negatively. Express concern using "I" statements: "I've noticed you're barely eating, and I'm worried about you." Don't force them to eat or monitor every mouthful — this increases anxiety. Offer to help find a specialist. Stay present and don't withdraw.
Can eating disorders be treated?
Yes. Most people with EDs achieve lasting recovery with the right treatment. Treatment takes time — from several months to several years depending on severity. Relapses are possible, but this doesn't mean failure — it's part of the recovery process. Early help significantly improves the outlook.
Do eating disorders only affect women?
No. Research suggests that around 25–40% of people with EDs are men. In men, EDs often present differently: not as a drive for thinness but as a drive for leanness and muscle mass (muscle dysmorphia). Due to stereotypes, men are less likely to seek help and less likely to receive the correct diagnosis.
Are eating disorders linked to social media?
Research shows a link between social media use (especially visual content) and body dissatisfaction, particularly in adolescents. This is not the sole cause of EDs — these disorders are multifactorial. But limiting exposure to content promoting unrealistic body standards can be part of prevention.
How do you tell "healthy eating" from orthorexia?
Healthy eating improves quality of life. Orthorexia diminishes it. Signs of orthorexia: anxiety and panic when "correct" food is unavailable; avoiding social events because of food; a sense of moral superiority based on diet; a significantly narrowed range of foods; thoughts about food occupying most of the day.
