I have had non-diet related complications this pregnancy.  My hormones sky rocketed (every pregnant woman's hormones do) and that brought about gall stones.  Luckily if you are a vegan the diet changes are not so dramatic.  The diet for gall bladder problems is a very bland vegan diet.  No fat, oils, or seasoned/spicy foods.  My Doctor for the gall problems loves the fact I am vegan.  It saved him a lot of time explaining why not to eat dairy and meat.  I do complain about the diet but only because I am having cravings :)  Unfortunately I have produced numerous stones in my gall bladder and the remedy for that is surgery.  I still have hopes that this will clear up on its own but the outlook is not good.  I guess you could say I am a true 'stoner'.
