Thrombocytopenia is a medical condition characterized by a low platelet count in the blood. Platelets are essential for blood clotting, and when their levels drop below normal, it can lead to increased bleeding and bruising. This condition can result from various factors, including bone marrow disorders, certain medications, or autoimmune diseases. Symptoms of thrombocytopenia may include easy bruising, prolonged bleeding from cuts, and spontaneous nosebleeds. Diagnosis typically involves blood tests to measure platelet levels, and treatment depends on the underlying cause. In some cases, addressing the root issue can restore platelet counts to normal levels.
