In short
Aplastic anaemia is a rare but serious blood disorder that occurs when damage to stem cells inside the bone marrow prevents it from making enough new blood cells. The condition can develop suddenly or slowly, with symptoms that can include fatigue, weakness, dizziness, shortness of breath, and easy bruising or bleeding. Causes can include autoimmune disorders, certain inherited gene changes, toxic substances, radiation therapy, chemotherapy, certain medicines, viral infections, or pregnancy, though the cause is unknown in many people. If not treated, it can lead to frequent infections, bleeding, a serious blood disorder, or heart problems such as an arrhythmia, an enlarged heart, or heart failure.

In many people, the cause is unknown. This is called idiopathic aplastic anemia.

Because of the risk of blood disorders, your doctor will monitor your condition and screen you for blood disorders regularly.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
