Thrombocytopenia

Thrombocytopenia is a blood disorder characterised by a lower-than-normal number of platelets, the tiny blood cells responsible for helping blood clot and preventing excessive bleeding. Platelets are produced in the bone marrow and circulate in the bloodstream. When their number falls significantly, the body may have difficulty controlling bleeding after injuries or spontaneously.

Thrombocytopenia can develop for several reasons. These include reduced platelet production in the bone marrow, increased platelet destruction by the immune system, certain infections, medications, liver disorders, nutritional deficiencies, and conditions that cause platelets to become trapped in an enlarged spleen. In some cases, the underlying cause may be temporary, while chronic conditions require ongoing medical care.

Mild thrombocytopenia may not cause noticeable symptoms. When platelet levels become very low, people may develop easy bruising, frequent nosebleeds, bleeding gums, prolonged bleeding from minor cuts, or tiny red or purple spots called petechiae on the skin. Women may also experience unusually heavy menstrual bleeding.

Diagnosis usually involves a complete blood count and additional tests to identify the underlying cause. Treatment depends on the severity and reason for the low platelet count. Management may include treating an underlying condition, adjusting medicines, corticosteroids, immune therapies, or platelet transfusions when clinically necessary. Regular medical monitoring helps reduce complications and maintain safe platelet levels.
