Emerging research reveals that iron deficiency not only impacts physical health but also subtly affects mental wellbeing, with symptoms often overlooked until anaemia develops.
Iron deficiency and iron-deficiency anaemia affect children and adults alike, and poor diet, including heavy reliance on fast food, is one common contributor. According to Dr Maram Issa, a therapeutic nutrition specialist quoted by Vetogate, the condition does not only affect the body. Because iron helps carry oxygen and supports the production of key neurotransmitters, low levels can also show up in mood, concentration and overall mental wellbeing.
Medical reviews and clinic guidance suggest the psychological signs can be easy to miss. A literature review in the European Psychiatry journal says iron-deficiency anaemia may be linked with fatigue, low mood, anxiety, restlessness, palpitations and headaches. Other symptom guides also point to irritability, poor concentration, dizziness, brain fog and reduced attention, while some people report a low mood that can be mistaken for a separate mental health problem.
Some of the more distinctive warning signs include unusual cravings for non-food items, known as pica, along with restless legs, cold hands and feet, brittle nails, hair thinning and pale skin. Health providers also note that symptoms can appear before full anaemia develops, so a simple blood test may be needed to check iron stores. Parents and caregivers should seek medical advice if several of these signs appear together, rather than assuming they are caused by stress, tiredness or a passing illness.
