Something to consider. (I don’t think “medicine has dismissed…,” I do think the body is very complex).
American microbiologists identified a gut bacteria strain that eliminates chronic fatigue syndrome symptoms.
Millions of people spend years being told their exhaustion is psychological. A Columbia University team compared gut microbiomes of patients with post exertional malaise and healthy controls and found consistent depletion of specific bacterial species, plus a measurable shift in bile acid metabolism, which points at a real biological mechanism.
The finding matters because it explains the symptom pattern. These bacteria help regulate bile acids, which affect energy metabolism and immune signalling. When the species vanish, the signals shift and the body behaves as if it is under sustained strain, so ordinary activity triggers a crash that can last days. This is not laziness, and it is not deconditioning. It is chemistry.
Clinically, the next step is faecal transplant trials and defined probiotics rather than guesswork capsules on a shelf. If a depleted strain is restored in the right conditions, some patients may see meaningful symptom relief. More importantly, a biomarker gives researchers a target, which is exactly what this field has lacked for forty years.
If the exhaustion of millions turns out to live in the gut, what else has medicine dismissed as imagination? 🔬
