What Are Hematological Diseases

There are many blood disorders, or hematological diseases, including rare genetic disorders, anemia, and clotting disorders. In addition to these disorders, patients can also have clotting disorders, which can cause excessive bleeding. Certain types of cancers, such as leukemia, affect the blood and the immune system. These conditions are diagnosed with a blood test. Often, a person’s platelet count is low, and they experience bleeding and bruising easily. In addition to thrombocytosis, people can also suffer from essential thrombocytosis, a disorder of platelet production.

The hematologist is part of the patient’s healthcare team

A hematologist is a medical professional specializing in the study of blood and its components. A hematologist will perform tests to diagnose a variety of disorders. These tests are used to treat many different conditions, including anemia and bleeding disorders. In addition to diagnosing these diseases, hematologists also manage patients with blood-clotting disorders.


The symptoms of hematological diseases vary, but they all involve impaired red blood cell production. In most cases, the red blood cell count is low, causing anemia. In some instances, anemia can be severe and lead to congestive heart failure. Other diseases, such as thrombocytopenia, cause excessive bleeding and excessive bruising. And sometimes, these conditions can even lead to death, such as in cancer patients.
