I am having diarrhea that has become bloody. What should I do about it. I'm sure it's diet related. I've been on chemo meds, off for a few days a pill that has caused mouth ulcers, bad taste, so have not eaten much of anything. Since I'm feeling better, I've been eating too much fats and sugars and fiber: dinner was two ears of corn and some kielbasa. Not a good mix. Any suggestions? I'll get the med name soon. Any free advise besides going to my local VA.
