Hello Kathy

I get hiccough occasionally. I am wondering if your hubands hiccoughs are actually burping related to gastric reflux, which I get a lot of – just another anutonomic nervous system malfunction. Get your husband to see his doctor about getting some Nexium for gastric reflux, it may take some weeks to really start working but it does work.. Nexium is know as a ‘proton pump inhibitor’. Proton pumps are the cells in the stomach that produce stomach acid – Nexium reduces the production of stomach acid.
Please tell your husband not to worry about loud burping in public, we have enough to worry about. Just burp say “Excuse me” and carry on – there are far worse habits performed by some people on purpose.
