What Should I Do If I Have a Low-Grade Fever That Doesnt Go Away for a Week?
Fever is a common phenomenon in daily life. Common fever can be easily relieved by physical methods or oral administration of antipyretics. If the fever persists, especially if it doesn't go away for a week, it may be caused by bacteria or viruses, or there may be other underlying diseases. If there are other obvious symptoms in the body, it is necessary to promptly go to the hospital for further examination to identify the cause and then carry out targeted treatment to try to bring down the fever as soon as possible.
If your low-grade fever persists for a week, it is recommended that you consult a respiratory medicine specialist and further improve relevant examinations to identify the cause and provide corresponding treatment. If the low-grade fever doesn't improve after a week, it is unlikely to be a common cold, as the symptoms of a common cold usually gradually resolve after 7 to 10 days. Persistent low-grade fever for a week is most commonly seen in infectious diseases, such as pneumonia, which can cause symptoms like low fever, cough, and sputum production. If it is pneumonia, active anti-infective treatment should be given. Another example is tuberculosis, which is one of the main causes of low-grade fever, and further chest radiography and other relevant examinations are needed for diagnosis. There are also some non-infectious diseases that can cause low-grade fever, such as systemic lupus erythematosus.
The symptoms of fever can actually be caused by many diseases, but most often by infections (bacteria, viruses, etc.). Some physical cooling methods can be used to alleviate the symptoms, and the cause should be identified as soon as possible for targeted treatment.
One of the reasons for fever symptoms is actually many diseases. Fever is mainly caused by an increase in the release of endogenous substances such as prostaglandins triggered by viruses, bacteria, and their metabolites, which act on the thermoregulatory center to raise the set point of body temperature.
There are many causes of fever. Fever caused by a viral cold usually improves significantly within a week, while fever caused by secondary bacterial infection can usually be detected through blood routine examination. Mild bronchitis may not be the cause of recurrent fever.
If the fever persists or recurs after temporarily going down, it is undoubtedly influenza, which is caused by viral infection. In the early stage, it is viral infection, and in the later stage, there is mixed infection with bacteria.
If the fever is caused by bacterial infection, it is necessary to consider the use of antibiotics. It is recommended to go to the hospital for a blood routine test to identify the cause of the fever and then carry out targeted treatment. Pay attention to frequently take a warm bath to reduce fever and drink plenty of water to help bring down the fever.
