I've noticed some red thin rice like things in my stool. i only see it on the toilet paper after wiping. could it be a parasite?

Parasites: Parasitic infections are certainly commonly seen in the stool. I've not seen a parasite that looks like red thin rice. Your concern prompts a number of questions, like what have you been eating? Have you had any foreign travel? Have you been sick with cough, diarrhea? If there are continued concerns, your stool can be examined in the laboratory for parasites to determine if there are issues.

Maybe or may not be: This may be parasites but it may not be. You need to see your physician and have your stool tested to answer this question.
