Thrombocytopenia is low blood platelet count. Platelets, also called thrombocytes, are colorless blood cells that help blood clot. Platelets stop bleeding by clumping together and forming plugs in blood vessel injuries.Thrombocytopenia (throm-boe-sie-toe-PEE-nee-uh) can happen because of conditions or medicines that affect the circulation, production or destruction of blood platelets. Thrombocytopenia can affect both children and adults.
Thrombocytopenia can be mild and cause no symptoms. If platelets become too low, there is a risk of serious bleeding after an injury or during surgery. Rarely, dangerous internal bleeding can occur.
Treatments address the underlying condition causing the low platelet count. In some cases, treatment includes a transfusion of donor platelets
