When you've been on acid blockers for years and still don't know why it started.

Reflux and heartburn are among the most common reasons people end up on acid-suppressing medication indefinitely. These drugs relieve symptoms effectively, but they were never designed to address a cause, and staying on them for years carries real costs: impaired absorption of B12, magnesium, calcium, and iron; a shifted gut microbiome; rebound acid production when you try to stop; and, in some cases, an increased tendency toward bacterial overgrowth. There's also a common misunderstanding at the center of it all — the problem often isn't too much acid. Sometimes it's too little, or a valve that isn't closing, a motility issue, an H. pylori infection, a hiatal hernia, or specific dietary and microbiome triggers.
