When does your husband get nausea? Before or after he eats? I believe GERD causes nausea because of the overproduction of stomach acids which puts your stomach in overdrive and causes pain and nausea (at least for me). Also has he been tested for H.Pylori or ulcers? When my ulcer flares, I get really bad nausea especially if my stomach is empty and goes away after a small snack.
