Has anyone heard of gerd causing yellow stool, upset stomach or fatigue?

yeah, I have inflammation of the duodenum.

My pain is above my belly button, and under my right rib.

I have this everyday!!

I also have real bad fatigue... Mandy

Fatigue and upset stomach for sure...I am not sure about the yellow stool,but I have heard of green because of the bile. You might try taking magnesium, it will help with the stomach spasms. Good Luck to you!

Ok...I'm trying to go off memory here, but my son had yellow stools once. And they were sort of loose, too, with some undigested food in them. And they smelled really foul.
I did some reading online and it sounded like malabsorption due to diarrhea- the food was moving through his intestines too quickly.
I called his doctor and she told me the same thing. She suspected an infection, but she said to let it pass and to give plenty of fluids. The idea was to not stop the flow out with any medicines or anything. It had gone on for about a day and half when I called her...she had me watch and give fluids, no fruits. If it got better in another day, great. If not, he needed to be seen.
Well, he got better so I guess the bug made its way through my son's system.
-That's just one example.

Another thing I read was it could be a bile blockage...

Have you had this for a long time?
