A member asked:

I take coumadin (warfarin) for an artificial valve. should diarrhea from a stomach bug make my inr go up or down?

A doctor has provided 1 answer

Either way: Depending on a number of factors, diarrhea can cause either increase or decrease in inr and the only way to find out is by having your blood tested. Given the importance of the issue, it would be prudent to contact your doctor.
