or. something very serious is happening. when you have a bleeding area in the stomach the hydrochloric acid will turn it jet black. and this will cause tarry stools. i have no idea if this is the underlying reason but it would be in your best interest to see a medical provider right away to determine if this black stool is blood or not. another possibility would be pepto bismol. if you were taking it.
i just had a jet black poop could this be from drinking a lot of beer i feel fine right now? . as i mentioned above i do have gerd. lately though i have had good brown poops. this is the first time i have had one this dark. i generally know when my gerd is bad because i will deal with a burning stomach heartburn and bad acid reflux. this is the main reason why i think it was caused by the beer i did drink a lot since it was my twenty-first birthday mainly budweiser.
