If you've been taking antacids — Gelusil, Digene, Eno — every time acidity strikes, you already know the uncomfortable truth: they work, but not for long. Within a few hours the burning returns, and you reach for the bottle again. This is not a coincidence. It is pharmacology doing exactly what it was designed to do — and nothing more.
Antacids are alkaline compounds — typically magnesium hydroxide, calcium carbonate, or aluminium hydroxide. When you swallow one, it reacts chemically with stomach acid to form water and a neutral salt. The pH in your stomach briefly rises, the burning sensation subsides, and you feel relief.
This reaction is real and fast. But it is purely mechanical — like pouring water onto a small flame. The wood is still there, still dry, still ready to burn again the moment the water evaporates.
An antacid does not change why your stomach is producing excess acid. It does not repair tissue. It does not address any structural or microbial issue. It buffers acid once, for 2–4 hours, then the cycle resumes.
Persistent acidity — what most patients present with — is almost never caused by the stomach spontaneously producing too much acid for no reason. In clinical practice, it traces back to one or more of three underlying problems.
1. Lower Esophageal Sphincter (LES) Weakness. The LES is the muscular valve between your esophagus and stomach. When it functions correctly, it opens to allow food down and snaps shut to prevent acid reflux. In GERD and chronic acidity, this valve becomes lax — either from years of overeating, excess caffeine, lying down after meals, or elevated intra-abdominal pressure. When the LES doesn't close fully, even normal levels of stomach acid wash back into the esophagus. An antacid reduces the acid temporarily, but does nothing to restore valve tone. The reflux mechanism remains completely intact.
2. Damaged Gastric and Esophageal Lining. Repeated acid exposure damages the mucosa — the protective lining of the stomach and esophagus. This damaged lining becomes hypersensitive, meaning it registers discomfort at acid concentrations that a healthy lining would tolerate without issue. Healing this lining requires specific mucosa-regenerating interventions: adequate zinc, glutamine, and anti-inflammatory botanical compounds. Antacids do not provide any of these. They buffer acid around a wound without treating the wound itself.
3. H. Pylori Infection. Helicobacter pylori is a bacterium that colonises the gastric mucosa and is present in approximately 44–57% of the Indian adult population, according to published epidemiological data. H. Pylori disrupts the protective mucus layer, elevates gastrin secretion, and directly causes chronic gastritis, ulcers, and treatment-resistant acidity. It is detectable via a simple stool antigen test or urea breath test. Antacids do not eradicate H. Pylori. In fact, by altering the gastric environment repeatedly, they can allow H. Pylori to persist more comfortably.
Using antacids occasionally for situational discomfort — a large meal, a late dinner — is generally harmless. The problem is chronic daily use, which is extremely common among acidity patients in India.
Acid rebound is the first consequence. When antacids repeatedly neutralise stomach acid, the body detects falling acid levels and compensates by upregulating acid-secreting parietal cells. The result: when you stop taking the antacid, acid output actually exceeds your baseline. This is the physiological reason so many patients feel they "can't stop" — stopping feels worse, so they continue indefinitely.
Mineral depletion is the second consequence. Calcium-based antacids (like calcium carbonate) taken chronically can paradoxically cause hypercalcaemia and impair kidney function. Aluminium-containing antacids bind dietary phosphate in the gut, leading to phosphate depletion over time. Both reduce overall mineral bioavailability. Additionally, lowering stomach acid impairs the absorption of magnesium, iron, and B12 — micronutrients that require an acidic environment for proper absorption.
The bitter irony is that antacid dependency worsens the underlying physiology it was meant to help. The longer you rely on them without addressing root causes, the harder correction becomes.
Addressing chronic acidity properly means working through a structured sequence. First, testing for H. Pylori and treating it if present — this alone resolves a significant proportion of treatment-resistant acidity. Second, implementing a mucosa-healing protocol: specific dietary changes, elimination of known irritants (alcohol, NSAIDs, processed food), and targeted supplementation to restore lining integrity. Third, restoring LES tone through positional interventions, meal-timing adjustments, and where appropriate, specific exercises that reduce intra-abdominal pressure.
This is not a fast process. Mucosal healing takes 8–12 weeks minimum. But it is the only approach that produces lasting change rather than perpetual management.
At Thavira Health, our AYUSH-certified doctors approach acidity through this root-cause framework — running the relevant diagnostics, identifying which of the three underlying drivers is dominant in your case, and building a protocol accordingly. The goal is not to make you comfortable indefinitely on a medication. It is to reach the point where you no longer need one.
Our AYUSH doctors identify the actual cause — LES weakness, mucosal damage, or H. Pylori — and treat it directly. 500+ patients have found permanent relief.
