D69.53: Heparin-induced thrombocytopenia, type 2
You don’t have enough platelets in your blood.
Some cells and substances in the blood affect blood clotting. Platelets are important for blood clotting. The platelets can stick to each other and thus seal wounds. If you have too few platelets, bleeds can occur. These may only be light bleeds into the skin or mucous membrane, for example. However, you may also have heavy nosebleeds or bleeding in the inner organs. You can bleed for a long time if you injure yourself.
You have too few platelets after you were given a particular medication. The medication inhibits blood clotting. The medication is given so that the blood does not coagulate in an uncontrolled way or too easily. But this medication may affect the quantity of platelets.
The immune system can be activated by the drug. The immune system can attack the platelets with antibodies. This will only occur after a few days. You may then have significantly too few platelets. The antibodies may also cause the platelets to stick together and block blood vessels in an uncontrolled way.
