When platelets decrease, the main symptom and sign are bleeding. Bleeding is very diverse, it can be subcutaneous hemorrhage, bleeding in the mucous membranes of the eyes, nose, or mouth, or more seriously, the patient has blood in urine, blood in the stool, or vomiting blood.

Hemorrhage from the skin due to idiopathic thrombocytopenia can occur in both children and adults. It is a symptom of the development of the disease and it differs between men and women of different ages. In young people, the disease is more common in women. At an older age, the disease appears to be more common in men. Children can get it after an episode of some common viruses. Viruses such as chickenpox, mumps, and measles have also been found to be associated with thrombocytopenic purpura.
