Removing the gallbladder due to gallstones is an increasingly common surgery.   It is done so on the basis that we can perform our digestive functions without the gallbladder.  While it is true that the liver continues to produce bile, the gallbladder is the one that squirts bile into our upper intestine in the presence of fats.   Taking care of your gallbladder will prevent gallstones and some dietary changes can really help here.
