If you plan to base your decision on what some doctor tells you then you may as well plan to let him butcher your gall bladder out. That is what he will want to do. That is how he makes money to pay for his boat.
However, if you wish to take you health into your own hands, you have come to the right place !!
You can do Liver Flushes and keep your gall bladder. Hundreds of people here do that and I am just one of them.
