Thanks for asking.
Based on your query, my opinion is as follows.
1. Stools can be red due to red beets.
2. Urine change in color is due to infection of urinary tract
3. Get your haemoglobin
evaluated. Platelet count
and INR is also necessary.
4. Upper GI bleed would have resulted in dark colored stools, as it is red, it is probably beet root. Stool microscopy or benzidine test will confirm it.
Hope it helps.
Any further queries, happy to help again.
