High stomach acid vs. Low stomach acid

How do I know which one I have? From what I read, the symptoms are similar. I get bloating, distension, upset stomach, indigestion, occasional loose stool and most recently a gnawing sensation in my stomach...not a pain...just feels like some sort of irritation of the stomach lining. Is there a test I can do to tell if my stomach acid is high or low?

 I am starting to forget what normal feels like. The stomach discomfort has become like a norm but i don't want it to be. 

Try 1/4 teaspoon of baking soda in 4-6 ounces of cold water first thing in the morning before eating or drinking anything.

Drink the baking soda solution.

Time how long it takes you to belch. Time up to five minutes.  If it takes longer than five minutes to belch, that is an indication of low acid. production.

To test for high acid, try drinking a little lemon juice or apple cider vinegar in water. If it gives you a lot heartburn, this would suggest high acid.

Correction: use undiluted apple cider vinegar or lemon juice to test for high acid.  I put that you should add water by mistake.

Thanks. Will try this.
