Immune Thrombocytopenia (ITP) is a rare autoimmune condition where the immune system mistakenly destroys healthy platelets or slows the production of new ones. Platelets help your blood clot, so people with ITP may experience a low platelet count and an increased risk of bruising or bleeding.
ITP affects people differently. Some feel completely well, while others notice symptoms that impact daily life. Explore information tailored for adults, children, and pregnancy.
ITP treatments work differently for everyone. Understanding how each treatment works and when treatment is needed can help you feel more confident and informed when discussing options with your healthcare team.
Hear from people living with ITP, clinicians, and researchers through the Beyond the Count podcast, and stay up to date with the latest news, stories, and developments in The Count magazine.
ITP happens when the immune system destroys platelets or slows their production. For many people, the exact trigger is unknown.
Doctors diagnose ITP by ruling out other causes of low platelets. Most people only need blood tests and a physical examination.
Seek urgent care if you have heavy bleeding, blood in urine or stool, severe headaches, or symptoms that feel unusual for you.
