This study examined whether people with ME/CFS have higher levels of inflammatory markers—substances in the blood that signal inflammation—compared to healthy people and those with regular fatigue. Researchers found that ME/CFS patients had significantly elevated levels of five different inflammatory markers, and these markers were linked to common ME/CFS symptoms like fatigue, brain fog, and flu-like feelings. The findings suggest that low-grade inflammation in the body may be contributing to ME/CFS symptoms.
