<<Disclaimer: Verify this information before applying it to your situation.>> Following the recent tread on this subject, it does make sense that we might still suffer some degree of malabsorption. It also makes sense to me that we might be deficient in electrolytes. We probably do lose more water through our stools. My own experience of high volume water intake, and heat intolerance is accompanied by a much greater propensity for perspiration than I have ever before experienced. I am showering twice each day, and there is still snow on the ground where I live. I can imagine that the shower will be going every hour or so in the summer. I can't remember the sources, but I think I read somewhere that many celiacs experience a reduced ability to sweat. It seems possible that there is a connection there too. Best Wishes, Ron Hoggan
