Diagnosing Hypochlorhydria

In order to diagnose hypochlorhydria (low Hydrochloric acid production in the stomach), there are a few different tests. The most accurate tests are performed by a doctor.  A common test is called The Heidelberg Test. The patient swallows a small device in the form of a vitamin size capsule. This device tracks the acid levels in the stomach as you swallow small amounts of baking soda, which neutralizes the stomach acid. If the stomach’s acid levels do not readjust after a small amount of baking soda, you may have hypochlorhydria. Basic blood tests can identify certain aspects of hypochlorhydria. Other urine and stool analysis aid in proper diagnosis.

There are also a few simple tests that can be done at home. The first one also involves baking soda. Mix 1/4 tsp. baking soda in 8 ounces of water. Drink the mixture first thing in the morning. The baking soda and the HCl in your stomach react to produce carbon dioxide gas, which will cause you to belch. If you do not belch within the first 5 minutes after drinking the mixture, that may be a sign that your stomach is not producing enough HCl on its own. People with normal HCl levels will consistently belch within 2-3 minutes.

Another at home test involves Betaine Hydrochloride capsules (not tablets). Start by taking 1 (525 milligram) capsule with a meal. If you feel a burning or warm, indigestion sensation, then you do not need the capsules, and your stomach is probably producing enough HCl. If you do not feel the burning, increase the amount up to 4 or 5 capsules. At whatever amount you start to feel the burning sensation, reduce the amount by one, and that is an estimation of the amount your stomach needs with meals.

Please remember to consult a doctor either before you try any of these tests or immediately after if you have any adverse reaction. If you have existing medical conditions or are pregnant or nursing, consult a doctor first.
