Over 65% of gall bladder ops are for women....and for we men who have experienced it, the pain levels are, apparently, worse than childbirth - why, at least with the latter, something productive is going on whereas the gall bladder is destructive - and for those wondering, the diaphragm is in total agony and there's a searing pain in your upper right shoulder and that's because of the autonomic nerve connections. That alone is a good indicator as to the gall bladder being on the blink.
