- Alpha Thalassemia
Thalassemia is an inherited problem. That means it is passed down from one or both parents through their genes. It affects the production of normal hemoglobin. Hemoglobin is a protein in red blood cells that carries oxygen to the tissues of the body.
- Aplastic Anemia
Aplastic anemia occurs when your bone marrow doesn’t make enough red and white blood cells, and platelets.
Hemolytic anemia is a disorder in which the red blood cells are destroyed faster than they can be made.
The most common cause of anemia is iron deficiency.
Overview of Anemia
Anemia is a common blood disorder. It occurs when there are fewer red blood cells than normal, or there is a low concentration of hemoglobin in the blood.
Detailed information on the different types of anemia, including aplastic anemia, anemia of folate deficiency, glucose-6-phosphate dehydrogenase deficiency, hemolytic anemia, iron deficiency anemia, megaloblastic anemia, and sickle cell disease
Anemia of B12 Deficiency
Vitamin B12 deficiency anemia is one of several types of megaloblastic anemia. Megaloblastic anemia is a type of anemia characterized by very large red blood cells.
- Beta Thalassemia
Thalassemia is an inherited blood disorder. That means it is passed down through the parent’s genes. It affects how hemoglobin is made. Hemoglobin is an iron-rich protein in red blood cells. It carries oxygen to the tissues of the body.

- Anemia of Folate Deficiency
Folate deficiency is the lack of folic acid in the blood. Folic acid is a B vitamin needed to make normal red blood cells. Low levels can cause megaloblastic anemia.
- G6PD Deficiency
G6PD deficiency is the lack of glucose-6-phosphate dehydrogenase (G6PD). G6PD is an enzyme found in red blood cells. A lack of it can cause hemolytic anemia. This is when the red blood cells are destroyed faster than they are made.
Hereditary hemochromatosis is one of the most common genetic disorders in the U.S. It is a metabolic disorder that causes increased absorption of iron from the digestive tract.

Immune Thrombocytopenic Purpura
Immune thrombocytopenic purpura (ITP) is a blood disorder characterized by a decrease in the number of platelets in the blood. Platelets are cells in the blood that help stop bleeding. A decrease in platelets can cause easy bruising, bleeding gums, and internal bleeding.

- Sickle Cell Disease
Sickle cell disease is a blood disorder in which the hemoglobin is damaged and can't carry oxygen to the tissues. These blood cells with the defective hemoglobin are sticky and can build up and block small blood vessels leading to pain and other complications of the disease.

Detailed information on thalassemias, including alpha thalassemia, beta thalassemia (Cooley's anemia)
Thrombocythemia is a type of disease in which the bone marrow makes too many red blood cells, white blood cells, or platelets. It results in too many platelets in the bone marrow. Too many platelets make normal clotting of blood difficult. This can result in too much clotting, or not enough clotting.
Thrombosis occurs when a clot blocks a blood vessel. It may be caused by injury, immobility and other factors.
A blood transfusion is a procedure in which you receive blood or blood components intravenously.
Polycythemia vera is a rare blood disorder in which there is an increase in all blood cells, particularly red blood cells. The increase in blood cells makes the blood thicker. This can lead to strokes or tissue and organ damage.
- Hemophilia in Children
Hemophilia is an inherited bleeding disorder. Children with hemophilia can’t stop bleeding because they don’t have enough clotting factor in their blood. Clotting factors are needed for blood to clot. Blood clots to prevent excessive bleeding.
- Hemophagocytic Lymphohistiocystosis
If you have hemophagocytic lymphohistiocytosis, your immune system does not work normally. Certain white blood cells — histiocytes and lymphocytes — attack your other blood cells. These abnormal blood cells accumulate in your spleen and liver, causing these organs to enlarge.
