Anemia (U.S. spelling) oranaemia is the most common blood disorder. It is caused by not having enoughred blood cells orhemoglobin in theblood.
Types (and causes) of anemia according to size of red blood cells
Microcytic anemia develops when red blood cells are smaller than usual because they don’t contain enough hemoglobin. Hemoglobin is a protein in red blood cells responsible for carrying oxygen to different parts of the body.
Normocytic anemia occurs when the number of red blood cells is lower than normal, and those cells contain less hemoglobin than they should. This type of anemia is often caused by an underlying chronic condition. Treatment for normocytic anemia typically involves addressing the underlying illness.
Macrocytic anemia is a blood condition where the bone marrow produces unusually large red blood cells. These oversized cells lack the necessary nutrients to function properly. While macrocytic anemia itself is not a severe condition, it can lead to serious health complications if left untreated.
