Apple cider vinegar capsules

I have had stomach issues for awhile now after having gallbladder stones removed. After everything I eat I have to go to the restroom almost immediately or shortly after with stomach aches/diarrhea.. In high school my stomach would also make noises due to possible nervousness? That would make people look at me weirdly or ask if I was hungry, not sure what that was but would acv help that too?
