Hi everyone. I had a followup EDG today. He removed a polyp two years ago and just wanted to make sure it had not returned. I had it a 9:00 am. this morning, but I am still really feeling drugged. I don't remember it taking this long to wear off last time. But, my question is, he said he biopsied a couple of places in the stomach that looked inflamed...is that gastritis? And secondly, he said I had a sliding hiatial hernia. What exactly is that? Thanks everyone for your answers.
