For the first time ever, researchers discover a strong association between chronic pain and gut bacteria. Fibromyalgia, a disease affecting approximately 4% of the population and growing, is characterized as full-body, chronic pain along with fatigue and cognitive impairment. Compared to a control group, a cohort of patients with fibromyalgia possessed a remarkably different microbiome, including 20 different gut bacteria species in either greater or lesser quantities. Scientists utilized techniques to ensure these microbial differences weren’t due to other factors, such as diet, age, medications, physical activity, etc. Greater microbial alterations were associated with more severe disease symptoms.

Takeaway: While this groundbreaking study shows a strong link between the microbiome and chronic, widespread pain, like with most diseases, scientists are uncertain whether the microbial alterations are the cause of the disease or a result. Further research will hopefully uncover this distinction, as well as help identify possible microbial diagnostic tools for the disease, since some patients wait as long as 4 to 5 years for a conclusive fibromyalgia diagnosis.
