How to identify the symptoms of high platelets

Platelets or thrombocytes play a very important role in the blood clotting process. Low platelet levels can increase the risk of bleeding, while an elevation contributes to the formation of blood clots that can be harmful to your health. A normal platelet count ranges from 150,000 to 450,000, but different health conditions can cause it to rise, affecting your health. At we explain how to identify the symptoms of high platelets.

When platelets are elevated in the blood, it could indicate what's called thrombocythaemia. There are various reasons for platelets to increase. Therefore, if the count is more than 450,000, it's important to consult a haematologist (a blood specialist) to determine the cause of the elevation and the most appropriate treatment.


Depending on the type of thrombocythaemia that's involved and its causes, the symptoms can manifest themselves in one way or another. Normally, the symptoms are not due to the elevation of the platelets as much as with the underlying condition in the body.


If a patient has a high platelet count, and depending on their red and white blood cell count, symptoms can include the following:

  • Headache and chest pain
  • Fatigue and weakness
  • Dizziness or light-headedness
  • Changes in vision
  • Tingling and numbness in the hands and feet
  • Abnormal bleeding after an injury
  • Nose bleeds and bleeding of the gums
  • Propensity to bruise easily
  • Bloody stool

It's very important to stress that the symptoms of high platelets are similar to those of many other conditions, making it extremely difficult to determine whether they are indeed elevated, unless the patient has a blood test. If your platelet count is greater than 450,000, you should consult a haematologist, who will carry out a series of tests to determine the cause of the problem.

Elevated platelets can result in the formation of blood clots, putting one's life at risk. Therefore, it's essential to consult a specialist and take control of the situation quickly.

Finding the cause of elevation appears to be really difficult.
