Best Practice Case Studies-Case 136 Asset 3 Gastrointestinal Issues in Sports

Video Transcription

Video Summary

This lecture reviewed gastrointestinal issues in athletes from both directions: how exercise affects the GI tract, and how GI disease affects performance. Dr. Deduck emphasized that sports medicine physicians must be “medicine specialists,” not just musculoskeletal experts.<br /><br />Key points included:<br />- GI symptoms are common, especially in runners, longer events, hot conditions, women, and younger female athletes.<br />- Exercise reduces blood flow to the gut, which can cause reflux, cramping, diarrhea, and even occult GI bleeding.<br />- Many traditional ideas are myths: you generally cannot “train the gut” to empty faster or tolerate large volumes during exercise.<br />- Practical advice includes eating well before activity, limiting food and fluid intake during competition, and avoiding NSAIDs before exercise because they can worsen GI ischemia.<br />- The FODMAP approach is highlighted as a useful, individualized strategy, especially reducing dairy first rather than immediately going gluten-free.<br />- Gluten-free, fasting, keto, and probiotic trends were cautioned against unless clearly indicated.<br /><br />For athletes with vomiting/diarrhea, he stressed the “four F’s”: fluids, food, fever, and function, plus careful return-to-play decisions. He also discussed choosing IV fluids appropriately and considering red flags like blood in stool, fever, and localized abdominal pain.
