Have you dealt with clients who have gotten water toxicity? i.e. too much water?
I work with people with eating disorders who sometimes drink well over a gallon of water a day, eat very little and, at times, experience dizziness and the inability to concentrate, and pass out(which is not the same as a hypoglycemic episode). My understanding is that this can be caused if someone drinks over six cups of water in under one hour. Does anyone have more information on the topic?
Here is a great article on Exercise-Associated Hyponatremia (EAH):
Hyponatremia is menntioned in the the article as well as fluid replacement guidlines. Hope this is helpful to you.
