Customer Question

I'm on warfarin. I went to the koi admin clinic (north side) on Friday with test results of 3.0. Saturday I started throwing up black throwup and black diahreah. No throw up over the last two days, not much diahrreah. Any thoughts? Dave Hursig(###) ###-####

This is Dr. David

your INR should be between 2-3

but taking warfain can make you bleed

and black diarrhea is a sign of bleeding from your esophagus or stomach.

you could have had some food poisoning or a bleed of a vein in your esophagus which can cause vomiting up black and black diarrhea.

you need to see a doctor to get blood test to see how much blood you may have lost

bleeding from your stomach is a serious thing.

you have to make sure the bleeding has stopped.

let me know if you have questions.
