Unless you want to invest the time and money into having tests preformed to measure the acid level in your stomach, you can give some of these over the counter natural suppliments a try and see if it helps. Hydrochloride tablets can be found in any healthfood store or the Vitamin Shoppe. They advice to start out slowly.
To test for sufficient hydrocloride in the stomach –

You need betaine hydrochloride tablets plus enzymes – they are available from health food shops.
Take half a tablet before the last mouthful of a main meal. Burning or indigestion means you have plenty of hydrochloric acid. Don’t take any more tablets. Use antacid or teaspoonful of bicarbonate to relieve discomfort.
If no burning or indigestion, next day take 1 tablet in the same way. If still no burning or indigestion, next day take 2 tablets in the same way. If still no burning or indigestion, then you need more acid.
There are other tests for stomach PH but they’re all invasive.
So if you need more acid, then you take 2 betaine hydrochloric acid tablets with main meals and 1 tablet with small meals. Swedish bitters can also help, as can wine with meals and eating calmly and enjoying food.
Aloe Vera Juice is very helpful on the digestive track. I use a ounce or two mixed with water once or twice a day and you can work up from there.
