Signs, Symptoms, and Complications of Thrombotic Thrombocytopenic Purpura
Blood clots, a low platelet count, and damaged red blood cells cause the signs and symptoms of thrombotic thrombocytopenic purpura (TTP).
The signs and symptoms include:
- Purplish bruises on the skin or mucous membranes (such as in the mouth). These bruises, called purpura, are caused by bleeding under the skin.
- Pinpoint-sized red or purple dots on the skin. These dots, called petechiae, often are found in groups and may look like a rash. Bleeding under the skin causes petechiae.
- Paleness or jaundice (a yellowish color of the skin or whites of the eyes).
- Fatigue (feeling very tired and weak).
- Fever.
- A fast heart rate or shortness of breath.
- Headache, speech changes, confusion, coma, stroke, or seizure.
- A low amount of urine, or protein or blood in the urine.
If you've had TTP and have any of these signs or symptoms, you may be having a relapse (flareup). Ask your doctor when to call him or her or seek emergency care.
