ITP is a blood disorder characterized by an abnormal decrease in the number of platelets in the blood.
Platelets are cells in the blood that help stop bleeding.
A decrease in platelets can result in easy bruising, bleeding gums, and internal bleeding. The symptoms may follow a viral illness, such as chickenpox. The disorder usually does not recur. Acute ITP is the most common form of the disorder. The onset of the disorder can happen at any age, and the symptoms can last a minimum of six months or several years.
