Can I Have an Eating Disorder if My Weight Looks ‘Normal’
Yes. You can have a serious problem with eating without looking the way you imagine somebody with an eating disorder should look.
Yes. You can have a serious problem with eating without looking the way you imagine somebody with an eating disorder should look.
The stereotype of an eating disorder as something that is always visible can delay help. Friends may say you “look fine”. You may compare yourself with photographs of very unwell people and conclude that your own behaviour cannot be serious.
That is not a safe way to assess an eating disorder.
NICE specifically warns against relying on BMI alone
NICE says professionals should not use a single measure such as BMI, or the length of time somebody has been unwell, to determine whether eating-disorder treatment should be offered.
Assessment can include changes in eating, restrictive behaviour, rapid weight change, disproportionate concern about weight or shape, social withdrawal, physical symptoms, compensatory behaviour and other mental-health problems.
The whole picture matters.
A body can hide what the mind is experiencing
Two people can look similar while having completely different relationships with food.
One may eat flexibly without distress. Another may spend hours planning, checking, restricting, binge eating, compensating or worrying about weight.
The psychological burden is not visible from a photograph.
Weight change is not the only physical concern
Eating-disorder behaviours can affect physical health even when somebody does not appear underweight.
NICE advises professionals assessing a suspected eating disorder to consider physical effects of malnutrition and compensatory behaviours and to assess whether urgent medical care is needed where physical health is compromised.
Tell your GP about dizziness, fainting, palpitations or other physical changes rather than assuming your weight makes them irrelevant.
Comments from other people can unintentionally delay help
“You don’t look like you have an eating disorder” may be intended as reassurance.
It can instead reinforce secrecy.
You do not need somebody else’s visual confirmation before seeking medical advice. If food, eating, weight or shape is dominating your thoughts or behaviour, describe that directly to a professional.
Treatment should follow need, not stereotype
If a clinician suspects an eating disorder after initial assessment, NICE recommends immediate referral to an age-appropriate community eating-disorder service for further assessment or treatment.
You do not have to become visibly thinner, physically collapse or reach a particular number before asking to be assessed.
