Classification Types of Anemia
Anemia is a condition in which there is a decrease in the number of red blood cells (RBCs) or hemoglobin in the blood. It can be classified into several types, depending on the underlying cause.
Iron Deficiency Anemia
Iron deficiency anemia is the most common type of anemia, and it occurs due to a lack of iron in the body. This type of anemia is usually caused by inadequate dietary intake of iron, impaired absorption of iron, or increased requirements for iron during periods of rapid growth, such as in infancy and adolescence.
Vitamin Deficiency Anemias
Vitamin deficiency anemias are caused by deficiencies of vitamins such as vitamin B12 and folate. Vitamin B12 deficiency anemia is most commonly caused by a lack of intrinsic factor, a protein produced in the stomach that is necessary for the absorption of vitamin B12. Folate deficiency anemia is caused by a lack of dietary intake of folate as well as impaired absorption of folate.
Aplastic Anemia
Aplastic anemia is a rare type of anemia that is caused by damage to the bone marrow, the spongy tissue inside the bones where new blood cells are made. This type of anemia can be caused by certain medications, exposure to certain chemicals, or certain forms of autoimmune diseases.
Hemolytic Anemia
Hemolytic anemia is a type of anemia caused by the premature destruction of red blood cells. This type of anemia can be caused by a variety of factors, including infections, autoimmune disorders, and certain medications.
Sickle Cell Anemia
Sickle cell anemia is an inherited blood disorder that is caused by a mutation in the hemoglobin gene. People with this condition have red blood cells that are shaped like sickles or crescents, which can cause blockages in the blood vessels and lead to pain and other complications.
