When elevated: High levels of pathogenic bacteria or parasites indicate potential infection or dysbiosis (microbial imbalance). This may correlate with digestive symptoms, inflammation, or compromised gut barrier function. When low: Low or absent levels of beneficial bacteria suggest dysbiosis or reduced microbial diversity. This can indicate prior antibiotic use, dietary factors, or conditions affecting normal gut flora establishment.
Gut health directly impacts nutrient absorption, immune function, and recovery—all critical for athletic performance. Identifying dysbiosis or pathogenic organisms can explain persistent GI distress, bloating, or fatigue that undermines training quality and adaptation.
