Having a low platelet count doesn’t cause symptoms. However, the bleeding that a low platelet count can cause may have the following signs and symptoms:
- Pinpoint red spots on the skin that often are found in groups and may look like a rash. The spots, called petechiae, are due to bleeding under the skin.
- Bruising or purplish areas on the skin or mucous membranes (such as in the mouth) due to bleeding under the skin. The bruises may occur for no known reason. This type of bruising is called purpura. More extensive bleeding can cause hematomas. A hematoma is a collection of clotted or partially clotted blood under the skin. It looks or feels like a lump.
- Nosebleeds or bleeding from the gums (for example, when dental work is done).
- Blood in the urine or stool (bowel movement).
Any kind of bleeding that's hard to stop could be a sign of ITP. This includes menstrual bleeding in women that’s heavier than usual.
Bleeding in the brain is rare, and the symptoms of bleeding in the brain may vary in severity.
A low number of platelets doesn't cause pain, fatigue (tiredness), problems concentrating, or any other symptoms.
