Anorexia vs. ARFID
Anorexia and ARFID (Avoidant/Restrictive Food Intake Disorder) can both involve eating very little, but they come from different places — and telling them apart matters for treatment.
The core distinction
Anorexia’s restriction is driven by body image and fear of weight gain. ARFID’s restriction has nothing to do with body image — it’s driven by sensory sensitivity, fear of choking or vomiting, or simple lack of interest in food.
Key differences
| Factor | Anorexia | ARFID |
|---|---|---|
| Body image | Central to the disorder | Not a factor |
| Typical onset | Most often adolescence | Often much earlier, in childhood |
| What drives avoidance | “I don’t want to gain weight” | Sensory issues, fear of choking, low interest in food |
| Nutritional pattern | Blanket reduction in quantity | Often narrower — specific foods/textures avoided |
Why they’re confused
Both can result in very limited diets and significant weight/growth concerns, especially in kids and teens, which is why an accurate diagnosis needs a clinician who screens for both.
When to seek help
Especially relevant for parents of picky eaters where the “pickiness” is affecting growth, nutrition, or daily life — that’s worth an evaluation, not just waiting it out.
