Acid Reflux and Dry Mouth

Can Acid Reflux cause a Dry Mouth? – Does Reflux Acid cause a Dry Mouth?

Have you ever noticed that when you have Acid Reflux you wake up in the morning or wake up at night with a dry mouth?  You’re not alone, a dry mouth is one of the many symptoms you can experience when you get acid reflux.  However you may not realise that it’s probably not the Acid Reflux itself which is causing the dry mouth – IT MAY BE THE OTHER WAY AROUD!

Dry Mouth and Acid Reflux is a vicious cycle

Here’s the problem.  A dry mouth will make your acid reflux worse.  Why is this?

Saliva is alkaline and will help to neutralise the stomach acid, and  chewing food is an important part of the digestion process. Dry mouth can interfere with this process, as the food in the esophagus would not be sufficiently wet with the alkaline saliva to counteract any stomach acid that would reflux into it from the stomach.


So Whats the solution? – You need to reduce the dry mouth in order to reduce the acid reflux.

What Can I do to stop or reduce the dry mouth?

  1. Drink plenty of water.  Small amounts frequently is the best way to go here.  Too much water may make the Acid Reflux flare up.  This is the best place to start.
  2. Try chewing gum or eating something that stimulates the saliva.

Are the medications for my Acid Reflux causing a dry mouth?

If you are using Proton-pump inhibitors (PPI) which are medications that suppress the production of acid in your stomach it is quite possible.

Common side effects of Proton-pump inhibitors are:

  • Headache
  • Diarrhoea
  • Abdominal pain
  • Nausea
  • Gas
  • Constipation
  • Dry mouth
  • Sleepiness

Ultimately the end goal here is to drink plenty of water regularly and in small sips should reduce the acid reflux.  Buy a packet of chewing gum as well and see if that makes a difference.
