What is the most common cause of high platelet count?
Infection. In both children and adults, infections are the most common cause of an elevated platelet count. 1 This elevation can be extreme, with platelet counts greater than 1 million cells per microliter.
What happens if the platelet count is high?
A high platelet count can cause blood clots to develop spontaneously. Normally, your blood begins to clot to prevent a massive loss of blood after an injury. In people with primary thrombocythemia, however, blood clots can form suddenly and for no apparent reason. Abnormal blood clotting can be dangerous.
Should I worry about a slightly elevated platelet count?
It is possible, however, that having high platelet counts can lead to the development of blood clots. If you have elevated platelets and are concerned about the risk of developing blood clots, talk to your healthcare providers about ways to reduce the risk of blood clots.
Can stress cause high platelets?
Stressful life events and anxiety usually cause an increase in platelet volume and activity through various mechanisms. Mean platelet volume (MPV), which is indicative of platelet size, is accepted as an indication of platelet activity.
What autoimmune disease causes high platelets?
Hughes syndrome, or antiphospholipid antibody syndrome (APS), is an autoimmune condition that causes thickening of the circulating blood. The immune system produces abnormal blood proteins called antiphospholipid antibodies, which cause blood platelets to clump together.
What medicines cause high platelet count?
Vinca alkaloids have the most convincing data to show that they can induce thrombocytosis through their thrombocyte-stimulating properties. Miconazole has been implicated in causing thrombocytosis and has a documented case validated by drug rechallenge. Iron, predictably, can cause a transient thrombocytosis.
What infections cause high platelets?
Any inflammatory process such as bacterial infection, neoplasia, sepsis, multiple trauma, burns, or pancreatitis that elevates serum IL levels (especially IL-6), may increase the circulating platelet count (2,3).
Can vitamin D deficiency cause high platelet count?
Conclusions: This study indicates, for the first time, that vitamin D deficiency is associated with a parallel increase in platelet number, suggesting that higher platelet numbers may be one of the possible mechanisms leading to a greater cardiovascular risk in obese subjects.
Can high platelets cause fatigue?
Essential thrombocythemia (throm-boe-sie-THEE-me-uh) is an uncommon disorder in which your body produces too many platelets. Platelets are the part of your blood that sticks together to form clots. This condition may cause you to feel fatigued and lightheaded and to experience headaches and vision changes.
How can I lower my platelet count?
Your doctor may suggest one of the following prescription drugs, perhaps along with low-dose aspirin, to reduce your platelet count:
- Hydroxyurea (Droxia, Hydrea.) …
- Anagrelide (Agrylin). …
- Interferon alfa-2b (Intron A) or peginterferon alfa-2a (Pegasys).
