Introduction
Fever refers to an elevated body temperature; high blood pressure does not cause fever. High blood pressure is usually caused by genetic factors or underlying conditions such as respiratory, kidney, or endocrine system diseases. Most cases develop gradually and are asymptomatic. Some individuals may experience symptoms such as headache, dizziness, fatigue, or palpitations. In certain cases, hypertensive patients may develop severe symptoms like shortness of breath or coma, but fever is typically not present.

High blood pressure is typically influenced by genetic factors or caused by conditions such as respiratory diseases, kidney diseases, or endocrine system disorders. Most hypertensive patients develop the condition gradually and have no obvious symptoms. Some patients may experience clinical manifestations such as headache, dizziness, fatigue, and palpitations. In addition, some individuals with high blood pressure may develop severe symptoms like shortness of breath or coma, but fever is generally not induced.

When a patient with high blood pressure develops fever, it is likely due to catching a cold or common infection caused by bacteria or viruses. Additionally, fever might also be triggered by conditions such as rheumatic diseases, hematologic disorders, or tumors. These conditions commonly lead to symptoms including increased heart rate, elevated body temperature, headache, dizziness, and limb weakness. It is recommended to visit a hospital for tests such as complete blood count, chest X-ray, or lung CT scan to identify the specific underlying cause and receive appropriate treatment accordingly.
