Idiopathic thrombocytopenic purpura (ITP) may have no symptoms. When signs and symptoms do occur, they may include:
- Easy or excessive bruising (purpura) — your skin naturally bruises and bleeds more easily as you age, but this shouldn't be confused with ITP
- Superficial bleeding into your skin that appears as a rash of pinpoint-sized reddish-purple spots (petechiae), usually on your lower legs
- Prolonged bleeding from cuts
- Spontaneous bleeding from nose
- Bleeding gums, especially after dental work
- Blood in urine or stools
- Unusually heavy menstrual flow
When to see a doctor
If you or your child has abnormal bleeding or bruising, or develops a rash of pinpoint-sized red spots, see your doctor. It's also important to seek medical advice if you're a woman who suddenly develops significantly increased menstrual bleeding, as this may be a sign of ITP.
Serious or widespread bleeding indicates an emergency and requires immediate care.
