What kind of help I need: I want to know what the cause is and what tests should be done.
Doctor's answer:
Persistent fever is a symptom, and conditions such as rheumatism, tuberculosis, chronic inflammation, and immune dysfunction can cause persistent low-grade fever. Long-term psychological stress and emotional instability can also disrupt the body's temperature regulation center, leading to unexplained persistent low-grade fever. Any issue in the body's systems may potentially cause persistent low-grade fever. The causes of high fever are often difficult to identify through routine blood, urine, and stool tests. Some high fevers caused by bacterial infections can only be detected through bacterial culture. It is important to note that high fever cannot be treated with medication without a clear diagnosis. Fever is one of the body's responses to fighting off diseases. Patients with low-grade fever who take antipyretic drugs may benefit from the treatment of their underlying conditions. Misuse of antipyretic drugs can lead to risks such as elevated white blood cell counts and aplastic anemia. Antipyretic drugs should only be considered when the body temperature reaches 38℃ or higher.Medical Advice:
Persistent low-grade fever should be treated with prompt medical attention and comprehensive examinations. Early symptoms of many malignancies or bacterial infections can also manifest as high fever. It is recommended to seek medical evaluation to prevent the underlying cause of high fever from worsening.
The above advice addresses the question, "How should intermittent high fever be managed, and what tests should be conducted?" It is hoped that this information is helpful to you. Wishing you good health!
