This is interesting, I've been having stomach issues for 6 months now and wondered if there was a connection to the auto immune system and Vitiligo. My GP diagnosed me with IBS 6 months ago, although this seems to be the standard diagnosis for most long term gut/stomach complaints. I first had pains, like trapped wind, in my bowels starting a couple of years ago but the pain would last a good 12 hours at a stretch, although it only happened 1 or twice a month. Recently though after taking Colofac for 2 months that pain has gone but now I seem to have high acid output in my stomach which is making me feel sick all the time. A barium enema revealed no abnormalities in the bowel and numerous blood tests have been normal. I'm going in for a Gastroenterology exam soon to have a look in my stomach. I believe there is some connection but I'm going to have to do the NHS run around for a year or so I reckon until they come to that conclusion.
