Why Does the Elderly Person Experience Fevers of Over 37 Degrees Every Afternoon?

Fever, Clinically Known as Pyrexia

When elderly individuals experience a fever of over 37°C every afternoon, it could be attributed to conditions such as tuberculosis, viral flu, hyperthyroidism, among others. It is recommended to identify the underlying cause before administering targeted medication. The details are as follows:

1. Tuberculosis

Elderly people tend to have weaker immune systems. If their lungs are infected with Mycobacterium tuberculosis, they may exhibit low-grade fever accompanied by symptoms like coughing and cold sweats. Treatment with medications such as Rifampicin Tablets and Isoniazid Tablets can be prescribed as per doctor's advice.

2. Viral Flu

As the organs of elderly individuals gradually decline, their immune function also weakens. Failure to take proper precautions against cold weather can make them susceptible to bacterial or viral infections, leading to flu symptoms such as nasal congestion, runny nose, sneezing, and fever. Medications like Compound Paracetamol and Amantadine Hydrochloride Capsules, Lianhua Qingwen Capsules, and Vitamin C Yinqiao Tablets can be prescribed according to doctor's instructions.

3. Hyperthyroidism

Due to abnormal thyroid hormone secretion, patients with hyperthyroidism often exhibit symptoms like low-grade fever, increased appetite, irritability, and excessive sweating caused by excess thyroxine. Medications such as Thiamazole Tablets and Propylthiouracil Tablets can be prescribed as per doctor's advice.

Additionally, the daily afternoon fever of over 37°C in elderly individuals may also be caused by chronic cholecystitis, chronic urinary tract infections, or tumor-related diseases. If symptoms persist or are accompanied by other discomforts, it is advised to seek medical attention promptly for targeted treatment after identifying the underlying cause.
