Thrombocytopeni
Thrombocytopeni, or thrombocytopenia, is a condition characterized by an abnormally low platelet count in the blood, often defined as fewer than 150,000 platelets per microliter in adults. Platelets are essential for normal hemostasis, and low counts increase the risk of prolonged bleeding after injury.
Causes include decreased production from bone marrow disorders (such as aplastic anemia, myelodysplastic syndromes, leukemia), nutrient
Symptoms range from none to mucocutaneous bleeding. Common signs include easy bruising, petechiae, nosebleeds, gum bleeding,
Diagnosis relies on a low platelet count seen in a complete blood count, with examination of a
Management is directed at the cause and bleeding risk. Mild cases without symptoms may be observed. Treatments
Prognosis varies with etiology. Some thrombocytopenias resolve with treatment of the underlying condition, while others become
