What is ITP?

Immune thrombocytopenia (ITP) is a rare autoimmune disorder that causes low platelet counts, leading to easy bruising, bleeding, and fatigue. In ITP, the body mistakenly attacks its own platelets, making it harder for blood to clot. This condition affects both adults and children, but its causes and treatment options vary.

Whether you are newly diagnosed with ITP or navigating its long-term effects, understanding ITP is crucial for managing its physical and psychosocial symptoms and improving quality of life. Learn more about ITP, its diagnosis, and treatment options to feel empowered to make informed decisions about your health and lifestyle.
