Hi. I ski out west, base altitude 8,000 feet. Summit 11,000 feet. I go one week a year. I watch what I eat an ski very agressively. Every year I come home bloated with a 5 lb. weight gain. I m now 63 years old and about to go skiing in a few weeks. Is there anything I can do to prevent this from happening. I know Diamox is useful for altitude sickness, though I don t think I really have this problem, other than expected mild shortness of breath in the first few days.
