DH had ilisotomy as a result of crohns about 12 weeks ago. Generally going okay, but as had a couple of episodes of stomach upset. During which time he gets severely dehydrated, VERY quickly, making him faint and feeing general crap. Currently having one of these episodes, projectile vomiting, and getting very dehydrated quickly. Anyone have experience of this during the early recovery stages and any tips would be MUCH appreciated !! Thanks...
