Social media influencers have been popularising the term “ferritin face” to describe physical symptoms they claim indicate low iron stores, including pale or grey skin, dark circles under the eyes, dry skin and hair loss. Medical experts have now confirmed that whilst these signs can point to iron deficiency, self-diagnosis based on appearance alone is problematic, according to The Guardian – UK news.
Ferritin is the protein that stores iron in the body, primarily in the liver, and releases it in a controlled way. Since the body does not produce iron, it must be obtained through diet. Blood tests measuring ferritin levels can provide a snapshot of the body’s iron reserves, though experts caution these levels are not always fully reliable.
According to guidelines from the National Institute for Health and Care Excellence, blood ferritin levels below 30 micrograms per litre indicate iron deficiency. However, Professor Sue Pavord of Oxford University hospitals noted that levels below 50 might already suggest a problem.
When appearance changes signal a real problem
Whilst the symptoms described by influencers can result from various factors including genetics, stress and dehydration, medical professionals acknowledge that low iron stores do affect appearance.
“Iron is needed for every single cell of the body. So if you are iron deficient, you will be very fatigued, have brain fog, your skin will look dull and saggy, you’ll look pale and tired,” Professor Pavord explained. She added that whilst iron deficiency cannot be diagnosed from facial appearance alone, it might suggest the condition is present.
Professor Toby Richards from the University of East London and the Iron Clinic said such changes are particularly pronounced in people with very low iron stores, describing them as “the really sick patients”.
Main causes and who is at risk
According to Professor Pavord, periods and pregnancies are the most common causes of low ferritin. Other factors include insufficient dietary iron intake or poor absorption, which can occur with conditions such as coeliac disease. Blood loss related to gastrointestinal problems like gastritis or polyps can also deplete iron stores.
Athletes may also experience low ferritin because of the high demand iron places on their bodies during intense physical activity.
Professor Richards emphasised the seriousness of the condition, stating it is “the leading cause of disability in women of reproductive ability”.
Those at high risk – including people with heavy periods, those who are pregnant or have had children, and vegetarians or vegans – should request a blood test. Richards recommended this should include a full blood count, ferritin level check, and tests for B12 and folate levels.
Treatment and the social media debate
Iron tablets are available over the counter at pharmacies. Professor Pavord said taking iron supplements without confirmed deficiency is unlikely to cause harm, particularly for young women who lose significant iron through menstruation.
However, Professor Richards warned that many commercial products contain lower doses than needed for proper treatment. Those with confirmed iron deficiency require full treatment doses and should have blood tests repeated after three months.
Medical opinion on the social media trend is mixed. Professor Pavord welcomed the increased awareness, arguing that iron deficiency should not be normalised among women struggling with fatigue. Professor Richards agreed that raising awareness of women’s health issues is beneficial.
Yet Dr Asiya Maula from The Health Suite urged caution, warning that people may identify with symptom lists and assume they have a deficiency without proper verification.
What this means for Poles in the UK
If you recognise symptoms such as persistent fatigue, pale skin, dark circles or unusual hair loss, you can book a blood test through your GP surgery free of charge on the NHS. When booking, request tests for ferritin, full blood count, B12 and folate to get a complete picture.
Women of childbearing age, pregnant women, vegetarians and vegans are particularly at risk and should not dismiss ongoing tiredness as normal. If you have heavy periods or have recently given birth, mention this to your GP as it helps identify the cause.
Over-the-counter iron supplements from UK pharmacies such as Boots or Superdrug are safe to try, but check the dosage. If blood tests confirm deficiency, your GP can prescribe higher-dose iron tablets on NHS prescription. You should have repeat blood tests after three months of treatment to check whether iron levels have improved.
Older adults experiencing suspected iron deficiency should seek a full clinical assessment, as it may indicate gastrointestinal bleeding requiring investigation. Do not delay seeing your GP if you are over 50 and notice new symptoms.
