What should I do if an adult has a persistent high fever? Why does the high fever persist?

Having a cold or fever once or twice a year is a detoxification phenomenon, and everyone believes that this is a good thing. But if the high fever persists, it will be quite troublesome. This is dangerous not only for young children but also for adults. Therefore, if a high fever persists, you must pay enough attention.

Medically speaking, fever is a means or method of self-protection. Generally, there are the following situations: one is infection, such as virus or bacteria infecting the human body; the other is the presence of foreign matter in the body, which can be produced by the body itself, such as a tumor, or external, such as trauma infection. For the first situation, fundamentally speaking, the problem can only be truly solved by improving one's own immune ability and improving the body and various functions. When a high fever persists, it is recommended to go to the hospital for a check-up to determine the cause.

What tests should be done if the high fever persists

Fever is a common symptom of many diseases. If the fever does not subside for a long time, there are many possibilities. The most common cause is probably inflammation of some kind of body, the most common cause of which is infection of the lungs or upper respiratory tract. It may also be in other parts of the body such as the liver, urinary system, etc. If an abscess is formed, the fever will be more severe and more difficult to control. If it is caused by inflammation, blood tests, chest and abdominal films or CT scans should be done to find the pathogen. Because the disease is caused by antibiotic insensitivity or resistance, a drug sensitivity test is needed to find the appropriate antibiotic. In addition, tuberculosis and certain tumors can also cause long-term fever, but it is generally low-grade fever. Tuberculosis can be diagnosed by tuberculin test. If it is a tumor, such as lymphoma, it is necessary to look for tumor markers or imaging examinations such as CT and MR to find the location of the tumor. Consultation with a clinician to investigate the cause with appropriate testing is recommended.

What should I pay attention to in my diet when I have a high fever?

When a patient has a fever, his appetite is generally poor. Many family members are worried that fruits and vegetables are cold, and high-protein foods such as meat are "irritating foods" and will increase fever, so they only give the patient plain porridge for several days in a row. In fact, if the fever lasts for a long time, electrolytes such as potassium and sodium will be lost, and electrolyte imbalance is likely to occur. Therefore, in addition to excluding those irritating, greasy, fishy and meaty foods, in addition to white porridge, you can drink soy milk, milk, millet porridge, vegetable and fruit sweat, lean meat juice, etc. Fish, meat and vegetables can be chopped into porridge. If they have an appetite, they should also be encouraged to eat some fruits with more water content, increase the intake of vitamins and trace elements, and correct the electrolyte imbalance in the body to better promote recovery. In addition, you should pay attention to getting more rest and avoid fatigue in your daily life.
