I don't know if things are the same for you as they are for me because I had a subtotal & still have 2 in of colon left but when I had my kidney surgery in May my urologist overmedicated me with keflex & I ended up with C difficile infection, was extremely ill and almost died. Another person on here said their dr told them they always need to be on probiotics when they are on any antibiotics. I am on a probiotic permanently from my GI, it's not a standard one from the drug store but one from a health food store with certain cultures and also had to eat super yogurt from wegman's 3 times a day. My NEW urologist also put me on an over the counter probiotic in addition to this one & my GI said that was good too. You might want to check with your PCP or your surgeon about a probiotic.
Hope this helps and you feel better soon. We want good, funny stories from you not hurting stories:(
