Introduction

In general, fever refers to an elevated body temperature. Whether fever affects internal organs depends on its severity. If the temperature is not very high and is brought down promptly, it usually does not affect internal organs. However, if the fever persists and the temperature remains high, it may cause damage to internal organs. Patients with persistent high fever should seek timely medical evaluation and consultation at an outpatient clinic of a正规 hospital.

Generally speaking, fever refers to an elevated body temperature. Whether fever affects internal organs depends on its severity. If the fever is not very high and prompt cooling measures are taken, it usually does not affect internal organs. However, if the fever persists at a high temperature, it may adversely affect internal organs. The detailed analysis is as follows:

1. No effect

Fever is a symptom and mostly represents the body's normal defense response to illness. When fever occurs but the temperature is not significantly elevated, it generally has little impact on internal organs or cellular metabolism. In the early stages of fever, antipyretic medications are usually unnecessary. Drinking more warm water appropriately can help lower body temperature. Applying cold towels to the forehead or using external cooling patches are also helpful.

2. Possible effect

During fever, increased body temperature accelerates blood circulation, which may enhance metabolic activity, leading to greater consumption of water and nutrients in the body. Patients may experience symptoms such as thirst, fatigue, and muscle aches. If high fever persists, excessive loss of extracellular water and sodium ions may occur, potentially causing damage to internal organs including the brain, liver, and kidneys. In such cases, medications like ibuprofen sustained-release capsules or acetaminophen tablets may be recommended under medical supervision.

If a patient experiences persistent high fever that does not subside, timely consultation at an outpatient clinic of a正规 hospital is advised. It's important to identify the underlying cause and receive standardized treatment under a doctor's guidance to avoid delaying recovery.

If pertussis has entered the recovery phase, and the patient has completed a full course of standardized treatment, with daytime coughing nearly resolved and only occasional mild coughing at night—without other symptoms such as fever, shortness of breath, or vomiting—medication may generally be discontinued after medical evaluation.
