Bone marrow suppression is a condition where the bone marrow, responsible for producing blood cells, is unable to function properly. This can lead to a decrease in the production of red blood cells, white blood cells, and platelets, resulting in anemia, increased risk of infections, and bleeding problems. Causes of bone marrow suppression can include certain medications, chemotherapy, radiation therapy, and diseases like leukemia or aplastic anemia. Symptoms may vary but often include fatigue, weakness, and frequent infections. Treatment focuses on addressing the underlying cause and may involve medications, blood transfusions, or bone marrow transplants.
