What causes a chronic fever?

Chronic fever, often also called Fever of unknown origin (FUO), is a fever that is constantly repeated or does not know and does not have an immediate explanable cause, such as apparent viral or bacterial infection. Such a condition may have numerous causes and doctors recommend people not to ignore this symptom. The rate that Fuo is serious about depends on its source, but because it may indicate a serious illness, the visit to the doctor is guaranteed.

Many times doctors look at one of the obvious causes of chronic fever: infection in the body. This could be relatively hidden and may be caused by an abscess somewhere in the body or something like an infection of the urinary path. Cat fever, bacterial infections, sometimes develop symptoms such as chronic fever and swollen lymphatic glands, especially in children, and may persist for months. Doctors are often able to verify bacterial infection by blood tests or scan the body and treatment can eliminate fever.

Some types of viral infections may also causechronic fever. Patients who have undiagnosed chronic fatigue syndrome could have FUO. HIV can also manifest itself with a chronic or recurring fever.

There are cases where chronic fever is evidence of diseases that suppress the immune system. Conditions such as lupus, juvenile and adults rheumatoid arthritis and HIV/AIDS result in a relatively constant fever. In these cases, bacterial infections may not be actively present, but the body produces fever in response to what they think is a constant attack on its immune system. Alternatively, diseases such as sarcoidosis can cause the body to react chronic low degree fever.

are more serious cancer that can lead to chronic fever. Diseases such as lymphoma have an impact on the immune system and FUO may be an early symptom. They can also produce other forms of cancer.

body sometimesIt responds to injury by developing fever. If the bone is damaged or tissue damage occurs, the body could create a fever as an incorrectly directed healing reaction, which usually continues until treatment is completed. Alternatively, other unrelated health, such as heart disease, occasional blood pressure or infection in the heart, such as bacterial endocarditis, threatens its function.

imbalance in some hormones of the body can also lead to chronic fever. When people have conditions such as hyperthyroidism, where they produce too much thyroid hormone, they can run fever. This can be easily verified by testing blood.

The more benign cause of chronic fever is a reaction to certain medicines. Some people can continue to take medication, but when they use certain species, they can run a slight fever. In other patients, drug fever may be serious problems. If a fever is Burdenemoci or issueIic, drugs could be switched or ended.
