This very easy, at home test is basically free other than the cost of ¼ tsp of baking soda. This is a good one to do because it is safe and has no major cost involved.
This test works by creating a unique chemical reaction within your stomach that occurs when you mix baking soda with stomach acid (HCL). The natural results should be a carbon dioxide gas production which will cause you to burp.
This test does have many variables that can cause false positives or negatives. To minimize these variables and get a greater degree of accuracy, I recommend performing this test on 3 consecutive mornings to find an overall average.
It is also best to do this test first thing in the morning before eating or drinking anything. You are looking for a pattern, not a simple one-time “yes” or “no.”
There is no published data on this method and the reliability is up for question. The results can vary from person to person depending upon how the individual interprets what they are experiencing. However, I still like it as a baseline measure and it is simple enough that you can retest every month to see if you notice changes.
Here is How You Do The Test:
- Mix ¼ tsp of baking soda in 4-6 oz of cold water, first thing in the morning before eating or drinking anything.
- Drink the baking soda solution
- Time how long it takes for a burp or belch to come about. Go up to 5 minutes.
How to interpret the results
- If you have not burped or belched within 5 minutes then it is a sign of insufficient stomach acid production.
- If you have early and repeated belching than it may be due to too much stomach acid. However, it is important not to confuse these with small little burps from swallowing air when drinking the solution. Any belching after 3 minutes is an indication of low stomach acid production.
