What is the definition of thrombocytopenia?

Thrombocytopenia can occur when there is not enough platelets, cells in your blood that stick together to help it clot.

It is not a big problem for most people, but in some severe cases, you may bleed too much if you get injured or spontaneously in your eyes, gums, or bladder.
