Hi. I ve gone through your query and I can understand your anxiety. Exercise induced GERD is common & gulping air during exercise may relax the lower esophageal sphincter causing acid reflux & there by worsening the condition. Also GERD needs lifestyle modifications as the main stream of treatment I advice you to -Take PPI (ormeprazole, pantoprazole or rabeprazole - Avoid smoking & fatty foods, alcohol, chocolates, garlic, onion, coffee etc. - Prefer diet low in protein, fat and high in carbohydrates before workout. - keep yourself stress free as it is one of the trigger - Try to sleep in left lateral position & also avoid recumbency 2 hours after food Hope I have answered your query. Let me know if I can assist you further. Take care. Regards, Dr. Yogapriya V, General and family physician.
