Doctors say face alone cannot diagnose low iron — SkimNews

- Aziza Sesay said “ferritin face” is not a medical diagnosis and that pale skin, hair shedding or brittle nails can signal low iron or other conditions, making symptoms rather than looks the useful starting point.
- Drew Provan said it is “impossible” to determine someone’s ferritin from their face; pallor can accompany significant anaemia and fatigue can contribute to dark circles, but these visual signs are subjective and unreliable.
- British Society of Gastroenterology guidelines set ferritin below 15 micrograms per litre as absent iron stores and below 30 as generally low, noting that depletion can precede anaemia.
- Sue Pavord said iron deficiency is common and often under-diagnosed in women; she advised taking iron tablets on an empty stomach, ideally in the morning, and avoiding tea or coffee around the dose because they inhibit absorption.
- Lucy M said a later test found her ferritin at 12 micrograms per litre after developing palpitations, fatigue and hair loss in 2021 and receiving an initial diagnosis of generalized anxiety disorder; she described looking grey with dull, brittle hair.
- Drew Provan said blood tests confirm iron deficiency, establish its cause and guide treatment; causes include heavy periods, low dietary iron, gastrointestinal blood loss and problems absorbing iron through the gut.
- Aziza Sesay called social media a “double-edged sword,” saying it can encourage people to seek help but also lead them to incorrectly diagnose themselves from a short video; she said skin-colour changes are less obvious in people with darker skin.
Why it matters: For women, whom haematologist Dr Sue Pavord says often have under-diagnosed iron deficiency, the 30 micrograms-per-litre low-store threshold makes social-media symptom checks a prompt for blood testing, not self-diagnosis. Testing separates depleted iron stores from anaemia and guides treatment for causes such as heavy periods or gastrointestinal blood loss.
