John Kang WebMD | Types Of Anemia

Specialists like John Kang WebMD highly encourage individuals to learn more about the different types of blood conditions. There are three major types of blood conditions: blood disorders, bleeding disorders, and blood cancers. Anemia is the most common blood disorder. Blood clots and hemophilia are bleeding disorders. Lymphoma, leukemia, and myeloma are the most common of blood cancers.

Some disorders are further broken down into several kinds. It is crucial to know the symptoms of a specific condition because many signs look and feel alike. The right treatment highly depends on the specific condition you have.

In another post, John Kang WebMD focused his discussion on the three most common types of blood cancers. In this post, he will be discussing the different types of anemia.


John Kang WebMD states Anemia affects the body’s ability to produce red blood cells (RBCs). It causes insufficiency or improper function of RBCs. A low level of hemoglobin often indicates that one has anemia. It is considered low when a man’s hemoglobin value is less than 13.5 gm/dl or when a woman’s hemoglobin value is less than 12.0 gm/dl. Although the required hemoglobin value for women is lower, menstruating and pregnant women are more at risk of having this blood disorder.

John Kang WebMD says that Anemia is often overlooked because the symptoms are not apparent in some cases. Sometimes, the only way to know if one has anemia is to undergo a blood test. While many people still do not know if they have anemia, reports show that about 3 million Americans have anemia and about 1.62 billion people, worldwide.

Poor diet and intestinal disorders increase the risk of developing anemia. Chronic disorders, such as liver disease, thyroid disease, kidney disease, autoimmune disease, and inflammatory bowel disease, likewise increase the chances of developing the disorder.

Types of Anemia

  • Iron-deficiency anemia is the most common kind of anemia. Blood loss, low levels of iron, and poor absorption of iron usually cause this type of anemia. People who have undergone gastric bypass surgery are often iron-deficient.
  • The need for iron is higher during pregnancy and childbirth. Iron-deficiency anemia often causes pregnancy-related anemia.
  • Vitamin-deficiency anemia is usually caused by low levels of folic acid or vitamin B12. Vitamin-deficiency anemia can further result in pernicious anemia. The latter type occurs when the gastrointestinal tract cannot absorb vitamin B12.
  • Sickle cell anemia is an inherited condition which causes RBCs to be rigid and for circulation to be clogged. Hemoglobin protein is also affected.
  • Hemolytic anemia causes RBCs to break up in the spleen or in the bloodstream. Congenital abnormalities, infections, autoimmune disorders, and mechanical causes, such as aneurysms or leaking heart valves, often result in hemolytic anemia. Congenital hemolytic anemia may affect RBC structure and hemoglobin.
  • Aplastic anemia is a condition wherein the bone marrow stops producing RBCs, white blood cells, and platelets. Deficiency or destruction of blood-forming cells in the bone marrow results in this type of anemia. There are cases when the body’s own immune system causes the destruction of these stem cells. Aplastic anemia can also be caused by viral infections, exposure to toxic chemicals, and ionizing radiation.

Symptoms Common to All Types of Anemia

Lack of oxygen, John Kang WebMD says, is the most common symptom of anemia. This causes dizziness, paleness of skin, irregular heartbeat, shortness of breath, and chain pains. Sometimes, anemic people feel lightheaded. However, in milder cases of anemia, there may be no symptoms at all.
