Celiac Disease

A discussion of Celiac Disease may seem to be an unusual article for the WMNL, in that, on the surface it does not seem to be directly relevant to wilderness or remote medicine.  However it is extremely relevant because Celiac Disease is a very common problem that deeply affects people’s lives, presenting difficult challenges to outdoorspeople . This is one of those medical problems that plagues outdoor schools, expeditions, and wilderness programs. Impacting our nutrition and the common foods we eat, Celiac Disease tears at the very foundation of programs, trips, and life itself.

If someone is properly hydrated, they will need to void every 2 – 3 hours, and the urine should be a light amber color. If they are dehydrated, they will void less often and will produce dark, concentrated urine.
