Over the last couple of years, I ve had a couple of severe indigestion episodes which progress from feeling lightheaded and pale, to perspiring and finally lapsing into unconsciousness for several minutes. This has always occurred when I ve eaten very little and after consuming about 3 beers. Once I regain consciousness, which the last time took about 3 minutes, I still felt nauseous for about 5 minutes, but then it subsided and I felt fine. I would also perspire profusely. I m 61, male, and in better-than-average physical condition.
