Aplastic anaemia

Aplastic anaemia is a serious condition affecting the blood, where the bone marrow and stem cells do not produce enough blood cells. It is also called bone marrow failure and can happen suddenly (acute) or develop over a period of time (chronic). This page explains about aplastic anaemia, how it is treated and what to expect when a child comes to Great Ormond Street Hospital (GOSH) for treatment.
