Turns out, your gut bacteria might spill the beans on chronic fatigue and long Covid! Scientists used AI to analyze gut bugs and found they could spot ME/CFS with 90% accuracy—way better than current tests. People with chronic fatigue had less of a key fatty acid (butyrate) and other nutrients. Bonus: gut data even predicted who struggled with sleep and mood. This could mean faster, more accurate diagnoses for thousands dealing with these mysterious illnesses. #Health #BodyHealth #GutHealth
