Symptom 18. Low-Grade Fever: The Subtle Indicator of Diverticulitis
Running a low-grade fever is a frequently reported symptom of diverticulitis. This isn’t the high temperature associated with the flu or a bad cold, but rather a slight elevation in the body’s baseline temperature, often hovering between 99.5°F (37.5°C) and 100.9°F (38.3°C).
Fevers are a natural defense mechanism employed by the body to create an unfavorable environment for invading pathogens. In the case of diverticulitis, the pathogens in question are the bacteria causing the infection in the diverticula. The raised body temperature can impede the growth and reproduction of these bacteria, aiding in the body’s fight against the infection.
A low-grade fever is easy to overlook, given its subtlety. Some may attribute it to a tough day at work, an intense workout, or a minor bug. However, when it persists for an extended period or is accompanied by other symptoms of diverticulitis, it becomes more significant.
In addition to serving as a marker of the body’s defense response, the fever is also a trigger for several other physiological processes. For example, the rise in temperature boosts the function of certain immune cells, accelerating the healing process.
While fevers are typically harmless, they can lead to some uncomfortable symptoms, such as chills or sweating. Also, in some cases, prolonged fevers, even low-grade ones, may take a toll on the body, leading to fatigue or a general sense of malaise. (18)
