Aplastic anaemia is a rare blood disease caused by bone marrow not working properly. Your bone marrow inside your bones is where stem cells are made. These stem cells turn into the different types of blood cells your body needs to keep you healthy. In aplastic anaemia, bone marrow doesn’t make enough of these stem cells. What’s in this factsheet? This factsheet tells you a bit more about bone marrow and aplastic anaemia. It explains what aplastic anaemia is, the symptoms you might notice or feel if you have it, and what can be done to help. You can view or download the factsheet as a PDF here: Aplastic Anaemia (age group 12-16) Or order it as a printed booklet here.
