What Are the Signs and Symptoms of Idiopathic Thrombocytopenic Purpura?

Having a low platelet count doesn’t cause symptoms. The bleeding caused by a low platelet count may have the following signs or symptoms.

• Pinpoint red spots on the skin (frequently the legs) that can often be 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 apparent reason. This type of bruising is called purpura. More extensive bleeding can create a three-dimensional mass called a hematoma.
• 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 heavy menstrual bleeding in women

Bleeding in the brain is rare, and the symptoms of bleeding in the brain may vary in severity.

A low number of platelets won’t cause pain, fatigue (tiredness), difficulty concentrating, or any other symptoms.
