What could cause ongoing nausea and acid reflux for 6 months?

Worth an evaluation!: Gerd is common--present in about 70 million americans. As such, there are easy solutions if you have just symptoms. If however you have inflammation due to gerd, this can be progressive & needs to be controlled. Start with behavior & diet changes (see prior healthtap answers), add acid-blocker medications (either h2-blockers or ppi's). Get evaluated, especially if atypical, chronic &/or worsening.
