Could it be an increase in eating fatty foods around the holidays? That was mentioned to me when I had mine out, 4 months after giving birth when I was 5 months pregnant

I had 3 severe attacks in 2 days. Blood tests and an ultrasound confirmed that I had gallstones. The ER dr said that many women have gallbladder issues during or right after pregnancy because of an increase in eating fatty foods while pregnant or the way the pregnant body digests fatty foods - I can't remember which exactly, but anyway - just a thought.
OP - There are times when I eat greasy foods that I get stomach cramps following, but it's hit or miss and the only thing I can think of that is an affect of having my gallbladder out. The cramps are nothing compared to the attacks I had though so I'll take 'em.
