Platelet Disorders

Platelet disorders are a group of conditions that affect the number or function of platelets, the tiny blood cells responsible for forming clots and preventing excessive bleeding. These disorders may involve a reduced platelet count (thrombocytopenia), an increased platelet count (thrombocytosis), or platelets that do not function properly despite being present in normal numbers. Platelet disorders can be inherited or acquired due to infections, autoimmune diseases, medications, bone marrow disorders, or chronic illnesses.

Common symptoms include easy bruising, frequent nosebleeds, prolonged bleeding from cuts, bleeding gums, heavy menstrual bleeding, and the appearance of tiny red or purple spots on the skin known as petechiae. Severe cases may result in internal bleeding, requiring immediate medical attention.

Diagnosis typically involves a complete blood count (CBC), peripheral blood smear, platelet function tests, bleeding time assessment, and, when necessary, bone marrow examination. Identifying the underlying cause is essential for selecting the appropriate treatment.

Management depends on the specific disorder and its severity. Treatment options may include medications such as corticosteroids or immunosuppressants, platelet transfusions, treating the underlying disease, or avoiding medications that impair platelet function. Early diagnosis and proper medical care help reduce bleeding complications and improve overall quality of life for individuals affected by platelet disorders.
