Black poop! Should I be concerned?

I get sleeved in 2 days and I had a very dark/black stool. Research says this is due to blood in the stomach or esophogus (I have both esophogitis and gastritis). Has anyone gotten black stool during the high protein pre-op liquid diet phase? I hope this does not change my surgery date.

 
Talk to your surgeon ASAP....... you don't hide this kind of info......

Yes.... dark black usually means a bleed high in the intake track......

High Iron can turn it dark but not usually black......

Call your surgeon tomorrow morning and tell him.  It can be serious and the doctor needs to have this information. 

Definitely call your surgeon, but in the meantime try to not freak out too much. If by "research" you mean that you looked it up on Webmd or Google, you could be scaring yourself over nothing. Maybe.

Either way, the dr definitely needs to know about it ahead of time. Good luck!

 You need to contact your doctor/surgeon immediately and/or go to the ER now. This can be an indication that you're bleeding in your upper GI tract. Depending on cir****tances, this could be life threatening depending on how fast you are bleeding out. 

 It may also look like coffee grounds just an FYI

Hi there - yes black poop can be an indication of a GI bleed but it something you ate or took (ie: iron pills) can make your poop black. The technical term is melena. Also the coffee ground look is if you vomit blood, your poop does not look like coffee grounds. There is a simple test to determine if it is blood it is called a guaiac test and can be done in the clinic. I do not think you need to run to the ER, but you can call your PCP.

Remain calm, it could be absolutely nothing. It would be much more concerning if you were have the toilet full of bright red blood. Still call your clinic and have it checked out.
