Is it normal to get diarrhea from drinking cranberry juice? i've been drinking it to relieve bladder discomfort.

Cranberry juice: This is virtually worthless for bladder infection. It lowers the pH, making the urine more acidic, which should inhibit bacterial growth, but you would have to drink so much of this that you could drown in it. If you are having burning on urination check with your PCP to be sure you don't have a bladder infection. Good luck. Hope this helps.
