Every time I drink grape juice my stool is dark for a couple of days before going back to normal. Is it The grape juice causing that?

    I don't drink grape juice but I bet that's what's doing this, as long as you're not in pain!

      I've been having pain all week but that could be the ibs I was diagnosed with. But even when I haven't had pain I've always seemed to have darker than usual stool when I drink grape juice. I drank a whole large bottle last night and this morning.

    It does sound like it, if your stools return to normal afterwards. I’m presuming you are drinking the darker grape juice and not the white(?) Did you know though, that drinking too much of it is bad for you and it can cause anaemia

      It was a 64 OZ bottle I drank half yesterday and finished the other this morning. I 've pain all week in my lower abdomen that started to go away. But I had lighter colored bowel movements until today. The stool looked black but I drank a lot more yesterday and today than usual.

      It sounds like the grape juice. Take a break from it for a week and see if things go back to normal. Also, you sound like you need to cut back as it’s not only extra calories you have to think about, all that sugar is not good for you, plus, as I said, it can cause anaemia.

      I'll have to do that. My doctor told me losing weight would help with the ibs and nerd. And the stool color always changed back before.

      Well cutting back on the grape juice or stop drinking it altogether will definitely help you lose weight, there are a lot of calories in fruit juice.

    Are you drinking dark grape juice?  This would be the likely cause since your stools go back to normal.  Drinking a whole large bottle is too much. Taking so much of it is probably colouring your stools.  I would cut back on the amount of grape juice you are drinking.

      I drank the dark purple kind. And I drank a larger amount than normal over a short period of time and this time it looked black. But because of the amou t it seems like grape juice would cause it. Ive had lower abdominal pain this week but it likely be the ibs I was diagnosed with causing that. I had a colonoscopy 4 3/4 years ago and it didn't even fi d any polyps at all so it do t seem like it would be colon cancer.

    It's starting to go back to normal so I suspect it was the Juice. If I had bleeding it likely wouldn't have gone back to normal
