Need GI: You have some GI illness that needs to be followed up by the GI Dr. I assume placed you on the high dose of Omeprazole. If you do not have a GI doctor, than acquire one asap and make an appointment for a full evaluation. Best wishes.

See your doctor: If you have not gotten better in two weeks you need to see your doctor you may have a more serious problem that is not made better with omeprazole.

See your doctor asap: You need to see your doctor if the medication is not helping.
