Acid Reflux (GERD)

Most acid reflux is not caused by too much acid — which is why acid-blocking medications often provide only partial relief.

Acid reflux is one of the most common complaints in clinical practice — and one of the most overtreated with acid suppression. The paradox is that many cases of reflux are actually caused by insufficient stomach acid, not excess. When stomach acid is too low, digestion stalls, gas builds up, and contents push upward. Long-term PPI use has significant consequences; understanding the actual mechanism changes the treatment completely.

Low Acid, Not High

Many GERD cases involve insufficient stomach acid — low acid impairs gastric emptying and LES tone, causing reflux. The burning symptoms feel identical regardless of the direction of the problem.

H. Pylori Is Often Missed

H. pylori infection directly affects acid production and is found in a significant proportion of GERD patients. Testing and treating it often resolves long-standing reflux that acid suppression couldn't control.

PPI Consequences

Long-term proton pump inhibitor use impairs B12, magnesium, and calcium absorption; increases SIBO risk; and promotes gut dysbiosis. Finding the actual cause avoids these downstream effects.
