Causes of GI Distress During Endurance Events

During long endurance events like the one mentioned in the podcast, gastrointestinal distress can occur due to mechanical stress on the GI tract, decreased blood flow and oxygen to the gut, and dietary factors affecting digestion. The shock and strain from prolonged physical activity can lead to increased permeability in the gut, impacting its ability to retain contents. This can result in issues like leaky gut syndrome, especially in events where blood flow is redirected to other muscles.
