Artery problems in the abdomen can cause diarrhea and other symptoms.
This is a very serious problem, and if they referred you, you need to follow up.
An angiogram is the definitive test.
But, I suggest you ask them to scan your abdomen.
There could be indications of a vascular problem, if they did a scan.
If you get worse, it is serious...go right back to the ER.
