Is any of this happening?
Be seen today
Seek urgent same-day medical advice for black stools even if you otherwise feel well, repeated vomiting, worsening upper abdominal pain, difficulty keeping fluids down, or new marked weakness.

Does any of this apply?
Book an appointment
Arrange routine medical assessment if upper abdominal discomfort, nausea, poor appetite, or early fullness keeps returning or lasts more than a short period.
Also arrange follow-up for unexplained weight loss, persistent swallowing difficulty, or tiredness that may be caused by anemia.
And for anyone, someone who:
has a symptom that has lasted more than a couple of weeks without improving
The article also says
Black stools can also occur with iron tablets or medicines containing bismuth.
If you are uncertain about the cause, especially if the change is new, seek medical advice rather than assuming it is harmless.
