My wife after recovering from several rounds of cliff developed by antibiotics in the hospital continues to hav chronic diarrhea that will not clear up no matter what we do. I am wondering if after living for 67 years she has become allergic to gluten. He doctors have not offered this as a possibility but my oncologist happened to mention to me that this happened to his mother and after putting her on a gluten free diet her systems and has abated greatly. Could this be a possibility?
