What causes platelet count to fluctuate?
The platelet count is normally 140,000 to 440,000/mcL. However, the count can vary slightly according to menstrual cycle phase, decrease during near-term pregnancy (gestational thrombocytopenia), and increase in response to inflammatory cytokines (secondary, or reactive, thrombocytosis).
Why would platelets suddenly increase?
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.
Can platelet counts vary from day to day?
It is important that platelet counts not be done too often since the levels fluctuate, sometimes quite widely. One week the platelets may be 27, the next week 51, and the week after that 18 without any change in the person’s treatment or bleeding.
What happens if blood platelets increases?
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.
What does a slightly elevated platelet count mean?
Mild to moderately elevated platelet counts are commonly seen when chronic inflammation is present. In other cases a high platelet count can signal a more serious blood problem known as a myeloproliferative disorder (abnormal growth of blood cell elements within the bone marrow).
Can high platelets be nothing?
The presence of high platelets is rarely associated with a medical emergency. However, in some cases, high platelets may cause blood clotting, bleeding or stroke.
Can stress cause platelets to rise?
Stressful life events and anxiety usually cause an increase in platelet volume and activity through various mechanisms.
Can high platelets be caused by stress?
Research gives hint that platelets activation and reactivity is increased by mental stress. This leads to enhanced cross talk with the immune system via paracrine secretion, receptor interaction and formation of platelet leucocyte-aggregates.
What cancers cause high platelet count?
What cancers cause a high platelet count?
- Lymphoma.
- Breast cancer.
- Lung cancer.
- Ovarian cancer.
- Gastrointestinal cancer.
What does an elevated platelet count of 1 million mean?
This elevation can be extreme, with platelet counts greater than 1 million cells per microliter. The majority of people who experience this are asymptomatic but a small group of patients with other risk factors may develop blood clots. Platelet counts generally return to normal after resolution of the infection,…
How long does it take for platelets to return to normal?
Platelet counts generally return to normal after resolution of the infection, but this may take several weeks. In some patients, thrombocytosis may be a rebound effect after having thrombocytopenia (low platelets) during initial infection. 3
What causes reactive thrombocytosis (reactive platelet count)?
A series of acute and chronic infection has been associated with reactive thrombocytosis. Megakaryopoiesis is inhibited in the presence of an acute infection which may be due to a virus or bacteria. This can help suggest and identify what causes a high platelet count in a patient who is experiencing either a viral or bacterial infection.
How does hemolytic anemia affect platelet count?
If hemolytic anemia (anemia secondary to red blood cell fragmentation) results in the formation of very small red blood cells, these red blood cells may be inaccurately counted as platelets by the machine that performs the complete blood count.
