I am experiencing nausea (severity: moderate) , upper abdominal pain, fatigue and light sensitivity, usually feel like vomiting in the morning?

AM nausea: Is pregnancy a possibility? If not,inflammation of the stomach lining, peptic ulcer, pancreatitis or acute gall bladder disease are possibilities. Since your symptoms are persistent or recurring, an examination by a physician is needed. Appropriate tests will be ordered. In the meantime, if symptoms are very mild, eat a bland, fat free diet and drink flat ginger ale to relieve nausea.
