Iron deficiency: causes and safe treatment
Replacing iron stores is only part of care: the cause of the deficiency matters too. Learn about tests, food, medicine safety and follow-up.

Are iron deficiency and anaemia the same?
Iron helps make haemoglobin, which carries oxygen in red blood cells. Iron stores may become depleted; iron-deficiency anaemia can develop as deficiency progresses. However, not all anaemia is caused by low iron.
The cause needs investigation
Heavy periods or digestive bleeding, low intake and poor intestinal absorption can contribute. Needs rise at stages such as pregnancy. Tiredness, pallor or dizziness alone cannot establish the diagnosis; symptoms may have other causes.
A clinician interprets a full blood count, ferritin, a test used to assess iron stores, and other investigations when needed. Assuming diet is the only cause can overlook bleeding or absorption problems.
Treatment and monitoring
A clinician chooses oral iron or intravenous iron when needed; the same product, dose or duration does not suit everyone. Blood tests monitor response and replenishment of stores. Even if you feel better, agree when to stop treatment and when to return for review.
Daily life and medicine safety
- Include varied sources such as meat, pulses and iron-fortified foods in a balanced diet. Vitamin C foods help absorption of plant iron; diet does not replace necessary treatment.
- For constipation, nausea or abdominal discomfort, ask a clinician or pharmacist rather than changing the dose yourself. Clarify timing alongside other medicines and supplements.
- Keep iron medicines out of children’s reach. Do not use someone else’s prescription; unnecessary or excessive iron can be harmful.
When should you not wait?
Call 112 for chest pain, marked breathlessness at rest, fainting or severe bleeding. Vomiting blood or black, tar-like stools need urgent assessment; do not assume they are only from iron treatment. If a child may have swallowed iron tablets, call 114 for poison advice without waiting for symptoms; call 112 first for serious symptoms.
