 Scientists linked chronic fatigue to a deficiency in butyrate-producing bacteria.

Recent breakthroughs published in Cell Host & Microbe and Nature Medicine have uncovered a profound connection between the gut microbiome and Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). Researchers from Columbia University and the Jackson Laboratory found that patients suffering from this debilitating condition often lack specific health-promoting bacteria, most notably Faecalibacterium prausnitzii. This deficiency leads to a critical shortage of butyrate, a short-chain fatty acid essential for maintaining the gut barrier and regulating energy metabolism. Without these vital microbial components, the body enters what experts describe as a "gut-driven energy crisis," directly impacting a patient's physical and mental stamina.

The implications of these findings are transformative for the millions of people living with chronic fatigue. The studies demonstrated that the reduction of beneficial microbial species like Roseburia and Coprococcus is directly correlated with the severity of a patient's symptoms. By pinpointing these specific biological markers, scientists are now closer than ever to developing precise diagnostic tools and therapeutic interventions that target the microbiome. Rather than treating fatigue as a vague symptom, medical professionals can now look toward restorative gut treatments as a viable path to reclaiming energy and health.

Lyme disease infection, i.e. borreliosis, causes a decrease in butyrate... From Google: "Borrelia infection (Bb infection) is associated with a decrease in the relative abundance of beneficial gut bacteria that produce butyrate, such as Faecalibacterium, Subdologranulum, Marvinbryantia, and Coprococcus.". I was diagnosed with ME/CFS for 19 years before a specialist lab test revealed I had Lyme disease.
