Causes and Risks of High Platelet Count

Platelets are an important component of blood. The causes and risks associated with elevated platelet levels are analyzed as follows:

1. Causes

Platelet levels in the human body are not constant but fluctuate within a certain range. They may increase after physical exercise or during seasonal changes. Newborns, infants, and children may also experience physiological thrombocytosis. Additionally, platelet counts can be temporarily elevated after eating or exercising, or during menstruation.

2. Risks

Elevated platelet levels may trigger various bleeding symptoms, such as skin redness, petechiae (small bleeding spots), bloody stools, hematuria (blood in urine), nosebleeds, and gum bleeding, and could potentially lead to severe gastrointestinal or other digestive tract hemorrhages. Systemic adverse symptoms such as fatigue, lethargy, drowsiness, and limb pain may also occur. Some cases may present with headaches, dizziness, or vision deterioration.

When platelet levels are high, treatment under medical guidance may include medications such as ferrous sulfate tablets, enteric-coated aspirin tablets, and clopidogrel hydrogen sulfate tablets. In daily life, it is important to maintain healthy habits, avoid strenuous exercise, eat a balanced diet, and undergo regular check-ups to monitor platelet counts.
