It’s Not Necessarily Caused by Alcohol…

Something else to consider is that many of the serious health concerns that can lead to blood in the stool may not even be caused by alcohol. It’s possible that you’re an alcoholic, or someone who drinks casually, and you notice blood in your stool after drinking, but think about it this way…

If you drinking daily or almost every day, you’ll notice the blood in your stool after drinking but it’s possible the blood would be there either way, even if you weren’t drinking.

Black Stool After Drinking Alcohol?

If you’re worried that the doctor is just going to lecture you about your drinking habits or something along those lines, just remember that most doctor’s aren’t even giving this level of personal care to their patients. The doctor wants to see what’s wrong with you (blood in your stool), and make sure it’s nothing serious, then move on. They probably won’t even mention your drinking, and the alcohol consumption might not even be tied in with the bloody stool, so don’t worry about being judged for having a drinking problem, don’t let that prevent you from seeking care.
