Hemolytic anemia is a condition in which red blood cells are destroyed faster than the body can replace them. This can lead to anemia, or a shortage of red blood cells. Common causes of hemolytic anemia include autoimmune disorders, inherited genetic disorders, infections, and reactions to certain medications.
Autoimmune Disorders
Autoimmune disorders are caused by an overactive immune system that attacks the body's own red blood cells. Examples of autoimmune disorders that can cause hemolytic anemia include lupus, rheumatoid arthritis, and other autoimmune disorders.
Inherited Genetic Disorders
Inherited genetic disorders are conditions that are passed down through a family's genes. These can include sickle cell anemia and thalassemia, both of which lead to the destruction of red blood cells.
Infections
Certain infections can lead to hemolytic anemia, including malaria, babesiosis, and some types of bacterial and viral infections.
Reactions to Medications
Some medications can cause the destruction of red blood cells, leading to hemolytic anemia. These medications include penicillin, sulfa drugs, and certain chemotherapy drugs.
