D60-D64: Aplastic and other anaemias

The group of conditions known as aplastic and other anemias are disorders where your body doesn't produce enough new blood cells, leading to a deficiency in your blood. Aplastic anemia is a rare, potentially life-threatening condition caused by a decrease in the bone marrow's ability to produce all three types of blood cells: red blood cells, white blood cells, and platelets. Other kinds of anemias in this group may result from a problem with the body's ability to produce specific types of blood cells. Common symptoms across these conditions include fatigue, shortness of breath, rapid heart rate, pale skin, frequent or prolonged infections, unexplained or easy bruising, and nosebleeds or bleeding gums. These conditions progress slowly over time. Transmission of these anemias isn't typical; rather, they may occur due to genetic factors, exposure to certain toxins, chemotherapy, radiation therapy, or diseases that harm the bone marrow. All these anemias impact your body's circulatory or immune system to varying extents.
