anemia

Anemia, also called blood anemia, is a condition in which the number of red blood cells or the amount of hemoglobin in the blood is too low. This causes the body to carry less oxygen, which can lead to symptoms such as fatigue, dizziness, shortness of breath, or pale skin. Anemia can have various causes, including blood loss, lack of iron or vitamins, or a condition that disrupts the production of blood cells. In people with an incurable disease, anemia occurs regularly, for example from the disease itself or as a side effect of treatment such as chemotherapy. A blood test shows whether anemia is present and how severe it is.
