What Causes Worms In Stool And Vaginal Bleeding?

My friend to whom I was speaking just informed me she found bugs in her stool. She has a litany of physical ailments, is a survivor or breast cancer, pulmonary blood clots and high risk for pneumonia, intestinal problems, is bleeding from her vagina (she is 77), diarrhea and a hospital acquired infection unknown to her. I asked if it were C. diff and she has no idea only that she is being treated for it. She lives out of her car in the bay area of California. She just told me about seeing bug s about the size of a grain of rice. I asked if they could be worms and she replied that they have many legs and definitely are bugs.
