High Stomach Acid Causes Heartburn: Fact or Fiction?

Anyone who’s experienced heartburn will be familiar with the dreaded sensation of stomach acid spurting up your esophagus. It’s nauseating, it burns, and boy does it hurt! The question is, why is that acid coming back up? And if it’s all spilling out then surely you must have high stomach acid levels?


Acid reflux happens when the acid/mixed contents of your stomach leak through the valve connecting your stomach and esophagus. This valve is known as the lower esophageal sphincter muscle (LES) and its job is to keep the contents of your stomach IN your stomach. However, this valve can start to malfunction and remain open when your acid reflux levels are too low. This is because you need sufficient levels of stomach acid in your gut to trigger it to close. So when you have low stomach acid, the LES remains open and any acid IS in your stomach to reflux back up – which is what you experience as acid reflux causing heartburn.

“Okay but I still have too much stomach acid though, right?”

Wrong. See where we’re going with this… You’re likely (quite rightly) a bit confused now. Don’t worry, we’ve all been there! 

Here’s What You Need to Know:

  • Your esophagus is a narrow space, about 30mm in diameter.
  • Anything that’s filling up a narrow space is going to take up a lot of room.
  • This means that even the smallest amount of acid will feel like a LOT in that space.
  • This is why acid reflux attacks can feel like you have lots more acid in your esophagus than you do!

So DOES High Stomach Acid Cause heartburn?

The answer is: sometimes. But often not. Low stomach acid is one of the primary causes of heartburn and this is far too often overlooked. This means that people who don’t need strong medications like PPIs end up stuck on them for life instead of treating the root cause of their symptoms, as it’s been misdiagnosed to begin with. This is backed up by realms of research such as a recent study which shows the connection between low stomach acid and high incidences of acid reflux.

Ease Your Heartburn by Adding MORE Stomach Acid

Now that you know you need to increase your stomach acid to relieve your heartburn, it’s time to put a plan in action. There are lots of at-home remedies for heartburn such as apple cider vinegar that work by increasing acidity, and these can be helpful for irregular bouts of acid. However if you have more chronic symptoms, you need to start a consistent plan that involves gradually adding acidity to your stomach to stimulate natural acid production long term. Whilst the many at-home remedies for heartburn can help if you suffer “now and then”, a complete treatment plan is needed to really restore your natural stomach acidity back to where it should be.

And that’s where we come in! Our Reflux Inhibitor has been developed to increase acidity over a period of 120 days to naturally restore your optimal stomach acidity. This is part of our Heartburn Relief Kit which also contains a soothing and anti-inflammatory Acid Relief supplement to ease your symptoms and rebuild the protective lining of your gut and esophagus to protect it from acid damage.
