Someone I know was having Gall stone attackes, two doctors recomended that he remove the gallbladder right away,
At the meeting with the surgeon, the surgeon did a thourough invesitagtion and stated that in his opinion any surgery should be a last resort, he recomended that the patient start a diciplined diet and see if the stones give him any problems.
He stated that a large percentage of people have stones yet do not have any problems with the gallblader.
I know that it is considered a minor surgery. However as I once heard, the difference between small and big surgery, small is when its by someone else, big when its by you.
youtube gallbladder removal surgery and watch the surgery, I would not want to have it if it is not absolutly necessary.
Therefore, I think that you should get a few opinions and not jump for surgery.
