I've always thought I was a little more sensitive to altitude than the average flat-lander. Recently I've had more than one low energy day plus a few more aches and cramps than usual. I think I stay hydrated even to the point where I think I'm over doing it since I need to get up during the night several times. That's not a problem I have at home at an elevation of 250 feet so either I'm drinking too much or I'm not retaining the fluid I'm drinking. I drink liquids in the morning, noon and night. I eat fruit, including a banana a day while skiing. I have a fairly normal North American diet but with less red meat than average. I drink a significant amount of water and juice plus diet Coke, wine and sometimes a Martini. I know all of this isn't training table food but I list it so you know what I'm drinking.
My question is does anyone know of a connection between altitude and potassium deficiency, or anything else that might sap my energy? My symptoms are similar to a potassium shortage but potassium supplements call for one to three tablets a day and the tablets have only 3% MDA. Doesn't sound like supplements would help much to me but I'll try them on my next trip. I know it might be any one of a million things but I thought some of you folks with more experience in the mountains might have an idea of what I should try. My flat-lander physician says everything is OK when he's checked me but of course he's not there when I'm in the mountains. Anybody with any thoughts on what I should try?
