Is acid reflux related to snoring and hiccups?

Maybe: Snoring is more associated with the airway and may be reflective of sleep apnea. Hiccups are non-specific and reflect irritation to the diaphragm. Hiccups may be associated with acid reflux. Belching is also commonly associated with gerd.

Yes: I can't speak to the hiccup question, but gerd is definately linked to sleep apnea, of which robust snoring may be a sign. In other words, if you snore a lot, you may also have obstructive sleep apnea (osa). It is a serious disease that can greatly affect your health and longevity. People with osa are much more likely to have reflux dissease. Speak to your md about having a sleep test.

Sleep apnea: Yes. Snoring is a sign of sleep apnea- stopping breathing for at least 10 seconds at a time. The build up of pressure causes pressure on the stomach, causing acid to be forced back up the throat.
