Can a X-ray detect any stomach problems?

Typically, an x-ray is used to detect skeletal problems, as bones show up well in x-ray imagery. The stomach itself cannot be seen very well with an x-ray, however it is possible that x-ray images be taken of the stomach in order to identify an object inside of it.

okay this guy who wrote up there is wrong! it can show inflammation of the stomach, air bubbles, and it can lead docs to finding out if you have a mass or something but will not show well but it would possibly show an abnormality.
