Also, can having gallstones effect your menstrual cycle?
Not sure on the effect of the cycle, but my mom had gallstones for a long time, she had to stay away from anything spicy, anything with caffeine( well she limited herself).
Until finally it got so bad she had to have surgery, she one that was stuck, and the size of a lemon, Dr. said it was the biggest one he's seen. She's been fine ever since.
Sorry i couldnt be more help, next time i talk to her, i waill ask her some more about it. Good luck sweetie
any time your body is ill it can affect your cycle.
