kojiharmony Asked: Can an upper endoscopy detect gallbladder problems?

I'm scheduled to have an upper GI endoscopy tomorrow due to some stomach problems I've been having for the past year or so which include mainly indigestion, lots of gas, and at times sharp stomach pains. I've been noticing lately that the sharp pains I've been getting are more towards the right rib cage though, and am just wondering does this test reveal gallbladder problems? I'm an other wise healthy 20 year old male who is pretty thin (120lbs) so I know I'm not likely a typical gallbladder sufferer.
