Beta thalassaemia

Haemoglobin is the red-cell protein that carries oxygen. Beta thalassaemia results from changes in the gene used to make one part of haemoglobin. Some people have a carrier form with few or no symptoms; others develop anaemia of varying severity. Possible features include fatigue, pale skin, reduced exercise tolerance, breathlessness, or slower growth in children. The condition is inherited, so family history and reproductive planning can be relevant.

A clinician may review symptoms and family background, then use a blood test and specialised haemoglobin analysis to clarify the type. Do not start iron simply because anaemia is present: iron helps only when iron deficiency is confirmed. Keep specialist appointments, follow the recommended treatment plan, and tell clinicians about beta thalassaemia before new medicines or procedures. Genetic counselling and premarital screening may help couples understand reproductive options.

Arrange prompt assessment for worsening fatigue, breathlessness at rest, chest discomfort, fainting, fever, or a new yellow tinge to the skin or eyes. Seek urgent care for severe breathing difficulty, collapse, or confusion. If you already receive transfusions or treatment for iron overload, report new abdominal swelling, palpitations, or marked weakness to your specialist rather than waiting for a routine visit.

Ask which form of beta thalassaemia you have, whether relatives should be tested, how iron status will be checked, and whether genetic counselling or premarital screening is appropriate for you.
