I m 67 years old and overall in good health, last September I got very sick with diahrrea, lost about 15 lbs. They made me do many different test and the results were a shrunken gallbladder, they are also telling me that I may have Crohn s desease. The surgeon wants to remove the gallbladder, and the Gastroenteorologist wants to do a colonoscopy to check the small intestine, I m torn in what can be the best thing to do
