Consider low stomach acid as part of the underlying problem with these 33 ways to tell if you have low stomach acid.

Low stomach acid is one of the SIBO causes.

In fact, my own SIBO always returned due to low stomach acid.

Problems don’t go away with drugs and medication unless we fix the underlying problem. And this is why I am such a huge believer in functional and preventative medicine. 

If you want more context on the below, I have recorded a podcast episode all about this topic that you can listen to now.

What is Low Stomach Acid?

Low stomach acid, also called hypochlorhydria, is when the body doesn’t produce enough in order to break down proteins into essential amino acids and nutrients the body needs. (By the way, there is also something known as achlorhydria, which is even lower stomach acid than hypochlorhydria.)

While studying at The Institute for Integrative Nutrition, I learned that HCL converts or activates pepsinogen to pepsin which digests proteins. HCL naturally decreases as we age. I know, such a bummer.

Despite the fact that the drug industry tells us stomach acid is a bad thing, it is not. Well, at least not always. In fact, stomach acid is needed in order to break food down.

So oftentimes people will go to their doctors, tell them they are experiencing acid reflux and they will be given an antacid and sent along their way (or worse, a PPI – proton pump inhibitor). Neither of those things are inherently bad in and of themselves, but they are if you don’t actually have too much stomach acid.

The antacid and PPI, of course, only reduce stomach acid even more, masking a problem and causing a harsh ripple effect.

So how do you know if you have low stomach acid? 

It’s not always easy to know, but it can also be fairly obvious.

Beyond just low stomach acid symptoms

Beyond symptoms, there are various ways to test for low stomach acid.

For me personally, I always use this test for low stomach acid. Work with your doctor or nutritionist, as there are others as well. Make note that the low stomach acid test I was able to use cannot be used for everyone.

I have erosive gastritis with heartburn brought on by stress and I’ve also tested positive for Sibo after 3 courses of antibiotics for a uti..For the gastritis I was put on a PPI but after eating very bland for months (fish/rice) I changed to Ranitidine after hearing such bad things about PPI’s, but at best I still get a tenderness/heartburn in my upper abdomen (below breasts but top abdomen and right across) and if I eat too many carbs I’m even worse..I don’t want to go back on a PPI but I’m not fully recovering on Ranitidine plus I’ve just heard some very negative carcinogenic press on it as well..I really don’t know what to do..Do you think my initial gastritis could of been actually low stomach acid? Gastritis isn’t on your list..and I can’t use the test suggested as I’m on Ranitidine..can’t cope with this anymore it never ends 🙁 please help xx
