Home Stomach Acid Test 

Do you suffer from acid reflux / heartburn? 


Did you know that numerous research studies have now shown that stomach acid secretion declines with age and so the more likely cause of your acid reflux/heartburn is actually low stomach acid not high. 

Low stomach acid can lead to a buildup in pressure in the stomach and this pushes tiny amounts of stomach acid into your throat.

Other signs that your stomach acid could be low include 

  • Extreme fullness after meals

  • Belching

  • Heartburn/burning sensation

  • Gas, flatulence after meals

  • Indigestion

  • Constipation

  • Diarrhoea

  • Food allergies/sensitivities

  • Skin problems

  • Weak nails

  If stomach acid is low, antacids will make the problem worse even though they may bring temporary relief.

Home Test for Stomach Acid Levels


Do first thing in the morning, before eating or drinking anything except water.


  1.  Mix a quarter teaspoon of baking soda in 200ml or so of cold water,

  2. Drink the baking soda solution.

  3. Time how long it takes to belch.

  4. Time up to five minutes. If you have not belched within five minutes stop timing anyway.


  • Belching in under 2 minutes or early and repeated belching , possible excess stomach acid

  • Belching  within 2-3 minutes, stomach  acid is probably OK

  • No belching or only belching  after 3+  minutes , stomach acid is likely to be low
