Quick summary
- Six core patterns account for the vast majority of reflux: Liver-Stomach disharmony, Stomach Heat, Damp-Heat, Cold-deficiency, Stomach Yin deficiency, and Food stagnation.
- Tongue and pulse resolve most ambiguity in under a minute.
- Most chronic reflux is a combination, usually a deficiency root with an excess overlay.
- The order of treatment in combined patterns is what separates results from relapse.
Once you accept that reflux is a mechanism (rebellious Stomach Qi) driven by different roots, the next task is a clean differential diagnosis. This article lays out the six core patterns you'll actually see, how to confirm each on tongue and pulse, and, most importantly, how they combine. Because in chronic reflux, they almost always combine.
The six core patterns
The differentiation of reflux resolves into six recurring patterns. Learn to recognize each in isolation first, then learn how they layer. Each has a characteristic trigger, a characteristic tongue, and a characteristic pulse, and when all three agree, your diagnosis is secure.
| Feature | Pattern | Key signs · tongue · pulse |
|---|---|---|
| Liver Qi invading Stomach | Stress-triggered, sour reflux, rib/epigastric distension, sighing | Tongue: normal or red edges · Pulse: wiry |
| Stomach Heat (excess) | Strong burning, thirst for cold, bad breath, constipation | Tongue: red with yellow coat · Pulse: rapid, full |
| Damp-Heat in Middle Jiao | Burning + heaviness, sticky mouth, nausea, loose foul stool | Tongue: red, greasy yellow coat · Pulse: slippery, rapid |
| Spleen/Stomach deficiency-cold | Reflux worse when hungry, better with warmth, fatigue, loose stool | Tongue: pale, swollen, white coat · Pulse: weak, deep |
| Stomach Yin deficiency | Night burning, dry mouth/throat, hungry but no appetite | Tongue: red, peeled/cracked, little coat · Pulse: thready, rapid |
| Food stagnation | After overeating, fullness, foul belching, no appetite | Tongue: thick greasy coat · Pulse: slippery, forceful |
Liver invading Stomach: the most common excess
In modern practice, Liver Qi invading the Stomach (肝气犯胃) is arguably the most common reflux pattern, because stress is the most common aggravator. The Liver's smooth flow of Qi is disrupted by frustration or tension, and the stagnant Liver Qi 'invades' laterally into the Stomach, disrupting its descending function. The hallmark: reflux clearly worse with emotional stress, accompanied by hypochondriac or epigastric distension, sighing, and a wiry pulse. Over time this generates heat (Liver-Stomach heat) or combines with deficiency.
Heat vs. Yin deficiency: the trap within the trap
The most consequential distinction is between excess Stomach Heat and the empty heat of Stomach Yin deficiency. Both burn. But excess heat has a full, rapid pulse and a thick yellow coat, and responds to clearing herbs. Empty heat has a thready-rapid pulse and a red, peeled tongue with cracks, and clearing it with bitter-cold herbs damages the Yin further and worsens the burn. The tongue coating is the fastest differentiator: thick yellow (excess) vs. peeled/absent (Yin deficiency).
Tongue coating settles the heat question
Faced with a burning reflux, look at the coating before anything else. Thick and yellow → excess heat, clear it. Peeled, cracked, mirror-like → Yin deficiency empty heat, nourish it. Treating these two identically is the single most common cause of 'reflux that won't respond to treatment.'
How the patterns combine in real patients
Textbook cases present one clean pattern. Real chronic reflux almost never does. The most common combinations: Liver Qi stagnation ON a Spleen deficiency root (stress plus fatigue and loose stools), Damp-Heat ON a Spleen deficiency root (a deficient Spleen fails to transform fluids, damp accumulates, then generates heat), and Stomach Yin deficiency WITH residual Liver heat (a long-standing case that has burned through the fluids). Recognizing the combination is what lets you sequence the treatment correctly.
| Feature | Common combination | Treatment order |
|---|---|---|
| Liver Qi + Spleen deficiency | Most common chronic picture | Soothe Liver AND tonify Spleen together; don't over-move a deficient patient |
| Damp-Heat + Spleen deficiency | Deficiency generating damp then heat | Clear damp-heat first (short course), then rebuild the Spleen |
| Stomach Yin deficiency + Liver heat | Long-standing, burned-through fluids | Nourish Yin as the base, gently clear heat, never drain aggressively |
| Food stagnation on any root | Acute-on-chronic flare | Disperse the accumulation first, then return to the root pattern |
The sequencing principle
When patterns combine, the order of treatment is the diagnosis. The general rule: address acute excess overlays first (food stagnation, active damp-heat) to relieve the patient, but never lose sight of the deficiency root, and never drain a deficient patient hard enough to worsen the underlying weakness. In a Liver-plus-Spleen picture you treat both simultaneously; in a Damp-Heat-plus-Spleen picture you clear briefly then rebuild. Getting this order right is why two practitioners with the same pattern list get very different results.
The takeaway
Six patterns, confirmed by tongue and pulse, explain nearly all reflux. But the clinical skill is not naming one pattern, it's recognizing the combination and sequencing the treatment: relieve the acute overlay, protect the root, and never treat empty heat like full heat. Next in the series: turning this diagnosis into a treatment plan, starting with the H. pylori question.
