I used to have a once a week free day, I always had nachos. I love butter, cream and fatty meat. Every time I ate nachos I had intense gall bladder pain that would go on a few days. I finally had to cut it out afraid I'd end up having to have surgery.

It seemed to be the change in diet to a ton of carbs with fat that bothered me so much.

I also once received a goody basket at Christmas after about 6 weeks of straight low carb. I ate the fudge that resulted again in intense gall bladder pain.

Maybe the carbs are doing something to the liver that irritates the gall bladder?
