Hematologists work to identify and prevent blood and bone marrow diseases. They also study and treat the immune system, blood clotting, and blood vessels.
Health conditions that affect the blood can be life threatening, but effective treatment is often available. In the United States, blood diseases accounted for
Plasma
Red blood cells, or erythrocytes
White blood cells, or leukocytes
Platelets, or thrombocytes
Disorders and diseases of the blood can impair the many functions that blood performs.
Some common blood disorders are:
- Anemia: This happens when
low red blood cell or hemoglobin levels mean the cells do not transport oxygen effectively, leading to fatigue, pale skin, and other symptoms. - Blood clotting: Clotting helps wounds and injuries heal, but blood clots that form inside a blood vessel can create a blockage, which can be life threatening. If clots become dislodged and move through the heart to the lungs, a pulmonary embolism can form.
- Blood cancers: Cancers such as leukemia, myeloma, and lymphoma occur when blood cells start to divide uncontrollably without dying off at the end of their life cycle.
- Hemophilia: If a person has low levels of clotting factors in the blood, they can
bruise or bleed very easily. They may bleed for too long after a minor injury or surgery, or during menstruation. It affects around 18,000 people in the U.S. - Sickle cell disease: An inherited trait causes red blood cells to take on a crescent shape. It affects over
100,000 people in the U.S., mostly Black Americans. It can severely impact how blood functions and can be life threatening. - Thalassemia: This is also a type of inherited anemia in which the body produces an unusual form of hemoglobin. It affected around
1,000 people in the U.S. in 2008 and is most common in people from around the Mediterranean and parts of Asia.
If symptoms suggest a person may have a blood disorder, they should seek medical advice. A doctor may refer them to a specialist in blood disorders, known as a hematologist.

Blood is essential for maintaining the health and life of the human body. It has many functions, including delivering nutrients and oxygen. The four main components of blood are red blood cells, white blood cells, plasma, and platelets.
Problems that arise due to illness or blood loss can be life threatening, but effective treatment is available for many blood-related disorders.
