Hi Matt! I hope both you and your DW are on the mend soon.
I just wanted to tell you that I had the same pain and nausea when pregnant with my first. Turns out all those digestive issues from years before that Drs couldn't diagnose where gallstones. I have pregnancy induce gallbladder attacks (caused by the elevated levels of estrogen). At 20 weeks pregnant I was in such acute pain they opted to remove it. Fortunately the laproscopic (sp) surgery happened with in 24 hours of diagnoses so no time to really worry about it.
The surgery was very easy, only 4 small incisions, they had me under anesthesia for less than 10 minutes (!!!) and baby did great! He's now 4.5 and is fine! They told me early in the 2nd trimester is the best time to have to do this. Baby is big enough to handle the small amount of anesthesia but small enough to get around to pull the gallbladder out.
My prayers are with you and your family. I hope DW is able to manage it by a low fat, low dairy diet!
