What are the treatment options for iron deficiency anaemia?

A clinician first looks for why iron has fallen. A blood test can assess haemoglobin and iron stores, while your history may point to heavy menstrual bleeding, dietary restriction, blood loss from the digestive tract, or difficulty absorbing iron. The cause matters because iron replacement alone may not prevent the problem returning.

Iron supplementation is often taken by mouth. It can cause nausea, constipation, abdominal discomfort, or darker stools, so the product and schedule may need adjusting. Iron therapy given in a clinical setting may be considered when oral treatment is unsuitable, not tolerated, or insufficient for the situation.

Take iron exactly as prescribed and keep follow-up appointments so symptoms and blood results can be checked. Do not increase the dose yourself. Foods such as meat, beans, lentils, leafy vegetables, and iron-fortified products can support treatment; a nutrition counselling appointment can help you build a suitable plan.

If heavy periods are contributing, treatment may focus on reducing bleeding. Options can include a hormonal coil or tranexamic acid for heavy bleeding, depending on your medical history and reproductive plans. Tell the clinician about pregnancy, medicines, stomach symptoms, and any change in bowel habits.

Arrange medical assessment for persistent tiredness, breathlessness on ordinary activity, dizziness, paleness, or unusual cravings. Seek urgent help for severe breathlessness, chest pain, fainting, confusion, or heavy bleeding. New iron deficiency without an obvious explanation also deserves prompt assessment rather than self-treatment alone.

Ask what the blood tests show, what may be causing the deficiency, how long treatment should continue, and when results should be repeated. You can also ask which side effects need a call, whether your menstrual bleeding needs treatment, and whether a referral or further testing is appropriate.
