You Cannot Feel Whether Your Stomach Acid Is Low

Here is the list, from NIDDK. Pain, a burning feeling or discomfort in the upper abdomen. Feeling full too soon while eating. Feeling uncomfortably full after a small amount of food. Bloating, nausea or belching.

Read it again and notice what it does not say. It does not say low acid. It says indigestion, which NIDDK treats as a group of symptoms, not a cause. It even separates heartburn out as its own condition.

Most chronic cases turn out to be functional dyspepsia. NIDDK describes it as a disorder of how the gut and brain work together. It is real and it has real treatment. No capsule identifies it for you.

NIDDK names medicines that can cause this outright. The list is ordinary. Certain antibiotics. Pain relievers known as NSAIDs. Iron supplements. Bone medicines. GLP-1 medicines. Steroids.

It also names peptic ulcers and infections such as H. pylori. Those are found with tests. They are treated, not managed with a supplement trial.

Then there is the plain stuff. MedlinePlus lists eating too much or too fast. High fat foods. Eating while stressed. Smoking, alcohol and being tired. It also says to see a provider if this lasts more than two weeks.

This is where the aisle overpromises. The NIH Office of Dietary Supplements states it plainly: the FDA does not determine whether dietary supplements are effective before they are marketed.

Quality seals from groups such as NSF International and US Pharmacopeia mean something narrow. They say a product was properly made and holds what the label says. ODS adds that they do not guarantee it is safe or that it works.

ODS also asks you to tell every provider what you take. Keep a written record of it. That is the opposite of self diagnosing from a bottle. It is the order the plan follows.
