The last two weeks I have had a sudden onset of gastro symptoms including extreme bloating and discomfort, nausea, excessive belching with a rotten egg taste, excessive gas, periods of diarrhea and constipation. I have been diagnosed with gastro paresis, reflux, and hiatal hernia about a year ago. I have been taking nexium 40 mg/day, but it doesn t seem to be working. I have a doctor s appt. next week, but am seeking some advice for relief of symptoms.
