This inherited blood disorder prevents someone from making enough healthy haemoglobin to carry oxygen around the body, but it may not need treatment.
What is a haematologist?
A haematologist is a specialist doctor who treats conditions that affect the blood – such as leukaemia and haemophilia – and the organs that make the blood.

Sickle cell anaemia
