What signs and symptoms you might have

There are many signs (things you see) and symptoms (things you feel) of low platelets. Some people do not have any signs or symptoms at all. As your platelet count goes down, your risk for bleeding goes up. Additionally, your risk for other signs and symptoms may also go up. Talk with your doctor and nurse if you notice any of these.

When your platelet count is:	You may have:
More than 50,000 platelets per microliter of blood	Small bruises that develop easily or that cannot be explained
30,000-50,000 platelets per microliter of blood	Bruises that develop easily or that cannot be explained A greater risk for bleeding from even a minor injury
10,000-30,000 platelets per microliter of blood	Bleeding that may start for no known reason or that may take a long time to stop Large, raised bruises Bruises that look like a rash (petechiae) Bleeding in your mouth or nose Heavy periods for women A greater risk for bleeding inside the body from even a minor injury
Less than 10,000 platelets per microliter of blood	Bleeding that may start for no known reason or that may take a long time to stop Large, raised bruises Bruises that look like a rash (petechiae) Bleeding in your mouth or nose Heavy periods for women Bleeding in the brain. This is a rare, but serious, event

These signs are a signal that your platelet count is too low. Your risk for bleeding is greatest when your platelet count is less than 10,000 and some studies also suggest that the risk of bleeding increases with age.
