Chronic Fatigue Syndrome (CFS) is a complex, long-term illness that impacts multiple systems in the body. Characterised by extreme fatigue, CFS has a broad range of possible symptoms. One common symptom is low-grade fever.
What is a Low-grade Fever?
A low-grade fever is typically a body temperature between 99.5°F (37.5°C) and 100.4°F (38°C). Fevers are a natural response to infection or illness, as higher body heat can help immune cells work more effectively. However, in the context of CFS, a low-grade fever might not indicate an individual’s response to an infection.
Low-grade Fever as a Symptom of CFS
Some individuals with CFS report experiencing periods of low-grade fever. Unlike typical fevers, this fever generally does not go away with conventional fever-reducing medication and can persist indefinitely. This is because, in CFS, a fever might not be a response to an infection, but rather a manifestation of the illness itself.
The Impact of a Low-Grade Fever on CFS
A low-grade fever can exacerbate other symptoms of CFS, such as fatigue, muscle pain, and impaired concentration. Maintaining a higher body temperature requires energy, which could contribute to the fatigue experienced by individuals with CFS.
Treatment
Treating a low-grade fever in individuals with CFS can be challenging, as over-the-counter fever reducers may not be effective. Instead, treatment typically focuses on managing the symptoms of CFS holistically. This may involve a combination of lifestyle changes and medical treatments. As such, each individual’s treatment plan will be different, tailored to their specific symptoms and needs.
While a low-grade fever can be distressing, it is generally not cause for alarm. However, if you or someone else has CFS and is experiencing a persistent fever, it is important to seek medical advice to rule out any other potential causes of the fever.
