Ryan's District Boards

By C. E. Huggins NEW YORK (Reuters Health) - A history of acute mountain sickness may not predict future bouts of the condition, according to a team of Canadian researchers. Likewise, those who have never experienced such altitude sickness may not necessarily be protected against it in the future. The Wilderness Medical Society's current consensus guidelines to prevent acute mountain sickness (AMS) are partly based on an individual's prior history of the illness. "A previous history of AMS (or the absence of AMS) doesn't seem to be as informative as we used to think," lead study author Martin J. MacInnis, a doctoral candidate at the University of British Columbia, told Reuters Health via e-mail.
