Tarry? Sticky?: Foul smelling? - if yes then get it medically checked out to ensure that you don't have GI bleeding. ...Read more
Probably not: Some foods cause your stool to change color but oreos should not cause the stool changes you describe. I wouldn't worry if this issue occurred 1 time, but if you notice stool changes for more than a few days, see your doctor. ...Read more
It might..: It might be completely normal depending on what you ate. However, we would need to know what other symptoms you are presenting. If the stool turns black or has blood, mucus on it it would need further evaluation. If otherwise you are healthy I would just make sure that you eat plenty of fiber (fruits and vegetables), low fat diet in order to produce a healthy bowel movement. ...Read more
It can be serious: Dark stools can be a sign that you are bleeding somewhere in your gastrointestinal tract (GI system). The stool is black (melena) because the blood has been digested. It can indicate that you have an ulcer or lesion in the tract somewhere. You need to be seen by your PCP or a gastroenterologist. A basic stool test can help. ...Read more
My stool has been very dark brown/black the last 2 weeks and my appetite has been down. What could be causing this??
A simple stool:
Test obtained from your Primary Care Physician's Office will disclose any blood in your stool (which could explain the black stools) Otherwise your diet pretty much influences the color of your stools! Sounds like you need a "check up"...make an appointment TODAY!
Hope this helps and Good Luck

Hi should I worry if for the past couple of days my stool has been half brown half very dark brown very similar to black?
I don't think you: Need to worry, but I would continue to watch it. Very likely the dark brown digested products of something you ate or took (especially iron) were processed and collected up against your usual color stool. I predict in another day or two it will normalize. The most worrisome thing is if the black stool represents old blood is present. If it persists, see Doc; consider stool test for blood. ...Read more

Stool is darker in one area. Stool was normal sized and also normal in color. Mostly brown but at the end seemed way darker?
All brown colors: Of stool are normal. Abnormally light stools ("clay-colored") may be due to reduced bile associated with liver disease. All dark brown stools are normal UNLESS they are BLACK which suggests upper GI bleeding. Sometimes more or less hydration in one part of the stool may affect its brown color. I wouldn't worry about this any further. Stay well:) ...Read more
Normal for stool to change consistency in the same day? One is light brown/normal shape, next one is dark brown and pretty soft.
This can happen. Usually due to changes in diet. If you are consistently taking a fiber supplement, then less likely. You should consider regular fiber in the diet and more water intake.
It's best to discuss significant changes with your physician. May want to consider colonoscopy if you are adult age. ...Read more
I noticed today that my stool was a bit darker brown than usual. Definitely not black, just darker brown than it usually is. What caused this?
Most likely normal: Our stools can vary in color depending on what we eat. Some foods such as beets clearly do this, while the amount of fiber and protein can shift the color slightly. If you pass soft, well formed stools on a regular basis, don't feel pain with passing one, don't see any blood or black tar-like substance in or on it, then you most likely are fine. ...Read more
I ate like 11 Oreos earlier and I just had very dark stool - it looked near black in the bowl but brown when I wiped. No other symptoms. Normal?

Black, tarry stool?:
If the stool is black and like hot tar consistency, it's possible that there is blood in the stool.
Stool color varies dramatically with what foods you've eaten, dyes that may have been in processed food or in your case maybe even very large quantities of dark chocolate. ...Read more
Dark stools: Dark-colored stools may result from iron supplements, foods you eat (like a lot of spinach), substances (like peptobismol), but most significantly suggests bleeding. When blood is denatured by acid in your stomach, as from ulcers, stools will turn tarry ("melena"). Blood may also be ingested from nose bleeds, bleeding gums... Persistent melena (without obvious cause) ; symptoms warrants md visit. ...Read more
Probably nothing: But there are many causes of dark stools (blood, meds, diet, etc). Fortunately it is easy to tell by bringing a small sample to your md to test for blood. If blood is found a colonoscopy and upper endoscopy could be performed to rule out a source of bleeding. If no blood, it may just be diet or other normal cause. ...Read more
