Hi im a male and I don't know why I feel throwing up when I wake up?

Morning nausea. Pregnancy & gynecologic issues are ruled out by your male gender but otherwise causes of nausea below are not gender-specific. Distinguish inflammatory (ulcer, small bowel disease, gallbladder/ biliary problem, pancreatitis, uti), structural (partial obstruction, extrinsic impression against the gut), functional (gastroparesis, irritable bowel), anxiety/school refusal syndrome. See doc to be sure.
