Causes Symptoms Complications Diagnosis Treatment Outlook Prevention and treatment We include products we think are useful for our readers. What is primary thrombocythemia? Bone marrow is the spongelike tissue inside your bones. It contains cells that produce: red blood cells RBCs , which carry oxygen and nutrients white blood cells WBCs , which help fight infections platelets, which enable blood clotting A high platelet count can cause blood clots to develop spontaneously.
What causes primary thrombocythemia? This is a chronic condition and is caused by genetic mutation, but the reasons for this abnormality are uncertain. Reactive thrombocytosis is a temporary elevation of the blood cells in response to another condition. While the response itself is often a normal part of acute inflammatory processes, reactive thrombocytosis can be caused by cancer, anemia or certain auto-immune disorders. It generally resolves when the underlying condition is treated.
Platelets are important for the body as they clump or stick together in response to injury and prevent excessive bleeding. However, an abnormally high platelet count means that clotting could happen spontaneously. Blood clots may occur anywhere in the body, but are most common in the hands, feet and brain. Other symptoms of high platelet count include headaches, dizziness, weakness and fainting.
There are a number of treatment approaches for an abnormally low platelet count. If the thrombocytopenia is not causing physical symptoms, treatment is usually not required.
However, if a low platelet count is dangerously low or symptomatic, then the cause may need to be treated directly.

Because thrombocytosis isn't likely to cause symptoms, you probably won't know you have it unless a routine blood test reveals a higher than normal number of platelets.
If that occurs, your doctor will try to determine the reason. Bone marrow — spongy tissue inside your bones — contains stem cells that can become red blood cells, white blood cells or platelets. Platelets stick together, helping blood to form a clot that stops bleeding when you damage a blood vessel, such as when you cut yourself.
Thrombocytosis occurs when your body produces too many platelets. This is the more common type of thrombocytosis. The cause of this disorder is unclear but it often appears to be connected to mutations in a variety of genes. Your bone marrow produces too many of the cells that form platelets and these platelets are often abnormal.
This poses a much higher risk of clotting or bleeding complications than does reactive thrombocytosis. Thrombocytosis care at Mayo Clinic. Mayo Clinic does not endorse companies or products.
