Patients with mild essential thrombocytosis do not experience any symptoms and often find out they have the disease during a routine check-up, according to MPN Research Foundation. When symptoms occur, they may be due to blood vessel disturbance or bleeding.

One of the first symptoms of essential thrombocytosis is the formation of blood clots, reports Mayo Clinic. Blood clots often form in the legs, hands and brain. However, blood clots may form elsewhere, including the abdomen, notes the National Organization for Rare Diseases.

Symptoms of essential thrombocytosis often depend on the location of the blood clot, according to Mayo Clinic. Patients may experience headaches, a mildly enlarged spleen and temporary vision changes. Other patients experience throbbing and redness in their hands and feet. The blood clots can cause other complications, including stroke, heart attack and deep vein thrombosis, reports MPN Research Foundation.

In rare cases, the platelet count may exceed a million platelets in every microliter of blood, notes Mayo Clinic. In such cases, patients may experience easy bruising, excessive bleeding and bloody stools. Patients may also bleed from the respiratory tract, gastrointestinal tract and the urinary tract, according to MedlinePlus.
