I had my gallbladder removed laproscopically 6-26-08, and my period was due on the first of July. My cycles are usually right on time, if not early. I am not sexually active, so no chance of pregnancy or anything like that. My question is, is it possible that the surgery affected my menstrual cycle?
A friend of mine just had a gallbladder operation arthroscopically too, and her period was late, also! And I have found that any time I've had surgery, I've been late, too. As the previous poster said, surgery of any kind is very traumatic to your body. The anesthesia messes you up and the procedure itself causes an extreme stress on your body. So, it really shouldn't be all that surprising that it affected your cycle.
