Root cause of the whole saga: the Beehiiv subscribe form is a cross-origin iframe
we cannot restyle, and its interior is white, so it can never sit cleanly on the
navy plan card. Answer: change the surface, not the form. Both live states render
on ONE light Ocean Fog panel, the same surface the 219 live articles already use.
No trigger step: the field is visible on load per the v7.0 lock. Article-side
only, zero Beehiiv dependence. Every state shares one look.
DO NOT re-add border-radius or overflow:hidden to .capform: a rounded clip slices
the embed's own pill outline and leaves a visible break at the left end. On a light
panel the clip buys nothing, because there is no artifact left to hide. */

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.</p>
<p class="b">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.</p>
<p class="b">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.</p>

<div class="inner"><div class="big">2</div><h3>The causes already sitting in your cabinet</h3></div>
<p class="b">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.</p>
<p class="b">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.</p>
<p class="b">Then there is the plain stuff. <a href="https://medlineplus.gov/indigestion.html" target="_blank" rel="noopener">MedlinePlus</a> 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.</p>

<p class="b">This is where the aisle overpromises. The <a href="https://ods.od.nih.gov/factsheets/WYNTK-Consumer/" target="_blank" rel="noopener">NIH Office of Dietary Supplements</a> states it plainly: the FDA does not determine whether dietary supplements are effective before they are marketed.</p>
<p class="b">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.</p>
<p class="b">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.</p>
<div class="ac-pf-callout"><div class="n">Free first</div><div class="d">Slower meals, smaller portions and a week of notes cost nothing. They settle more of this than any bottle. Start there.</div></div>

<h2>Frequently Asked Questions</h2>
<details><summary>Does low stomach acid exist?</summary><div class="a">It does, and clinicians look for it in specific cases. It is not something a symptom quiz can confirm. The symptoms overlap with far more common causes, and NIDDK lists those first.</div></details>
<details><summary>Can I test my stomach acid at home?</summary><div class="a">The kitchen tests going around online are not diagnostic. If you want a real answer, ask your clinician for a real test.</div></details>
<details><summary>Should I try antacids instead?</summary><div class="a">That is a clinician's call. MedlinePlus notes that indigestion can be a sign of a more serious problem. It also notes you may need medicine for the symptoms. Both are reasons to be seen.</div></details>
<details><summary>Who should skip betaine and pepsin?</summary><div class="a">The label warns against use with a history of hypersensitivity to any ingredient. If you are pregnant or nursing, ask your health professional first. If you have an ulcer, or take NSAIDs or acid reducing medicine, clear it with your prescriber.</div></details>
