<<Disclaimer: Verify this information before applying it to your situation.>> My sister-in-law is gluten-intolerant, and follows a fairly careful GF diet. She has noticed several times that her digestive symptoms quickly worsen when she is at high altitude. We live in Colorado Springs at an altitude of ~6000 feet, and when she stays in the mountains (even for only a day or two) at altitudes around 8000 to 10000 feet, she has more frequent diarrhea and digestive discomfort. Anyone else experience a similar reaction to altitude? Denise is really wondering whether this reaction is unique or shared by others. Regards, Beth Jones [log in to unmask] Colorado Springs
