Thalassaemia in Children

Thalassaemia is an inherited condition affecting haemoglobin production. Some children are healthy carriers, while others develop significant anaemia and may need regular transfusions and long-term monitoring. The exact type is determined through blood testing and, when appropriate, genetic evaluation.

Common signs

What parents may notice

  • Persistent anaemia
  • Pallor and tiredness
  • Poor growth
  • Jaundice
  • Enlarged spleen
  • Need for repeated transfusions
  • Family history or carrier parents
  • Abnormal newborn or haemoglobin test
Possible reasons

What can cause it?

Thalassaemia is inherited through gene variants passed by parents. It is not caused by diet or infection. Carrier couples benefit from genetic counselling about future pregnancies.

When to book

When should your child be assessed?

  • A haemoglobin test suggests thalassaemia
  • Anaemia is not responding as expected to iron
  • The child needs transfusion planning
  • Iron overload monitoring is due
  • The family needs genetic or transplant-related counselling
Urgent warning signs

When to seek immediate care

  • Severe weakness or breathlessness
  • High fever in a regularly transfused child
  • A significant transfusion reaction
  • Severe abdominal pain or sudden pallor
  • Collapse or altered consciousness
At the specialist visit

How the concern may be evaluated

  • Growth, spleen and organ monitoring
  • Transfusion and iron-chelation planning
  • Genetic and transplant-related counselling when relevant
Prepare

What to do before the visit

  • Bring all haemoglobin reports
  • Bring transfusion dates and reaction history

Questions parents ask

The real questions, answered.

Not what we wish you'd ask. What you're actually thinking when you find this page.

Book a consultation
Is thalassaemia trait the same as thalassaemia major?

No. Carriers are usually well, while transfusion-dependent forms cause significant anaemia.

Should a child with thalassaemia trait take iron?

Only when iron deficiency is confirmed. Trait itself does not improve with routine iron.

Why is iron overload monitored?

Repeated transfusions can cause excess iron to collect in organs, so monitoring and chelation may be needed.

Can thalassaemia be cured?

Stem-cell transplantation can be curative for selected children, while suitability depends on many clinical factors.

Should parents be tested?

Parental carrier testing and genetic counselling can clarify inheritance and future-pregnancy risk.

Persistent symptoms deserve a clear next step.
