Sickle cell anemia and thalassemia are both inherited blood disorders that affect haemoglobin and red blood cells, but in different ways. In sickle cell anemia, abnormal haemoglobin makes red cells rigid and crescent‑shaped, causing blockages and pain crises. In thalassemia, the body makes too little normal haemoglobin, leading to pale, small red cells and chronic anemia. Symptoms can overlap, but diagnosis and treatment vary, requiring specialised care. Early detection and expert guidance — like that provided by Dr Nandini Hazarika, a paediatric haematologist — help families understand, manage and treat these conditions effectively for better long‑term health in children.
