Low blood platelets (thrombocytopenia) occur when platelet counts drop below normal, increasing bleeding risk. Causes include viral infections such as Dengue fever, autoimmune disorders like Immune thrombocytopenia, bone marrow diseases, chemotherapy, alcohol abuse, pregnancy complications, and certain medications. Severe bacterial infections treated with antibiotics from a reliable ceftriaxone injection supplier may also temporarily affect platelet levels. Treatment depends on the cause and severity. Mild cases require monitoring, while serious cases may need corticosteroids, immunoglobulins, platelet transfusions, or treatment of underlying infections. Early diagnosis, laboratory evaluation, and targeted therapy are essential to prevent complications such as internal bleeding or hemorrhage.
