What Chronic Gastritis Is
Chronic gastritis is the persistent inflammation of the gastric mucosa, classified by the Sydney Classification according to etiology, topography, and histological morphology. It is one of the most prevalent gastroenterological conditions worldwide, estimated to affect 80 to 90% of the adult population in developing countries such as Brazil.
H. pylori is responsible for 70 to 80% of cases, causing predominantly antral gastritis that may progress to peptic ulcer and, in a minority, to intestinal-type gastric carcinoma through the Correa cascade: chronic gastritis → atrophy → intestinal metaplasia → dysplasia → adenocarcinoma. Autoimmune gastritis (Type A) affects the gastric body and fundus, destroys parietal cells, and may lead to pernicious anemia from intrinsic factor deficiency.
The clinical picture is variable and frequently asymptomatic. When present, it manifests with epigastric pain or burning, early postprandial fullness, nausea, heartburn, and belching. Symptom intensity does not necessarily correlate with the degree of histological inflammation — many patients with severe gastritis are asymptomatic, while others with mild gastritis have intense symptoms.
Conventional Treatments
Treatment is directed by the identified etiology. Eradication of H. pylori, when present, is the most important intervention and is potentially modifying of disease progression.
CONVENTIONAL TREATMENTS FOR CHRONIC GASTRITIS
| INTERVENTION | INDICATION | CONSIDERATIONS |
|---|---|---|
| Triple / quadruple therapy | H. pylori eradication | PPI + amoxicillin + clarithromycin ± bismuth; 14 days |
| PPI (omeprazole, pantoprazole) | Acid symptoms; healing | Adjunct to eradication; symptomatic control |
| Antacids (aluminum hydroxide) | Occasional symptomatic relief | Do not modify natural history |
| Sucralfate | Mucosal protection; NSAID gastropathy | Adjunct use after eradication |
| IM Vitamin B12 | Autoimmune gastritis with pernicious anemia | Monthly replacement as intrinsic factor is not produced |
| Endoscopic surveillance | Extensive intestinal metaplasia; dysplasia | Protocol biopsies every 3–5 years |
How Acupuncture Works in Chronic Gastritis
Acupuncture acts on chronic gastritis through three main mechanisms: regulation of gastric motility and secretion via the vagus nerve, stimulation of mucosal healing through growth factors, and modulation of local inflammation via NF-κB.
Mechanism of Action in Chronic Gastritis
PC6 (Neiguan) — Gastric Neurovegetative Regulation
Stimulation of the median nerve → vagal activation → increase in gastric parasympathetic tone → regulation of acid secretion and antropyloric motility.
ST36 (Zusanli) — Mucosal Perfusion and VEGF
Increase in gastric submucosal blood flow (laser Doppler) and elevation of VEGF (vascular endothelial growth factor) → improvement of epithelial nutrition and mucosal healing.
ST44 (Neiting) — Acidity Regulation
Reduction in gastrin secretion and parietal cell activity; "cooling" effect on the inflamed gastric mucosa documented in pH-metry studies.
CV12 (Zhongwan) — Central Modulation
Central point of the epigastrium; stimulates gastric peristalsis and normalizes EGF (epithelial growth factor) in the mucosa — central regulatory protein of epithelial renewal.
Local Inflammatory Reduction
Inhibition of NF-κB and COX-2 in gastric mucosa cells → reduction of inflammatory PGE2 (different from NSAIDs, which block all PGE2 including the protective fraction) → healing with preservation of the mucosal barrier.
Scientific Evidence
Studies on acupuncture in chronic gastritis evaluate subjective clinical outcomes (symptom scores, quality of life) and objective ones (endoscopic activity index, histological markers of mucosal inflammation).

Modern Approach: Integrative Medical Acupuncture
Medical acupuncture in chronic gastritis is indicated primarily as an adjunct after H. pylori eradication and as a complementary treatment in post-inflammatory functional gastritis.
CLINICAL PROTOCOL IN CHRONIC GASTRITIS
| STAGE | INDICATION | PROTOCOL |
|---|---|---|
| Acute symptomatic phase | Epigastric pain, intense nausea | PC6 + ST44 + CV12; 2 sessions/week |
| Post-H. pylori eradication | Mucosal healing and dysmotility | PC6 + ST36 + CV12; 8–10 weeks |
| Autoimmune gastritis | Symptoms; does not reverse atrophy | ST36 + CV12 + BL21; monthly maintenance |
| NSAID gastropathy | On discontinuing NSAID or with continuous need | ST36 + ST44 + PC6; mucosal protection |
| Maintenance | Prevention of symptomatic recurrence | 1 session/month indefinitely |
When to See a Medical Acupuncturist
Preferential Indications
- Chronic gastritis with H. pylori already eradicated and persistent symptoms
- NSAID gastropathy with need for continuous use
- Functional gastritis without satisfactory response to PPI
- Autoimmune gastritis — functional symptoms
- Gastric symptoms in patients who prefer to reduce PPI
Do Not Postpone Conventional Evaluation
- Digestive bleeding: urgent endoscopy
- Involuntary weight loss + anorexia: oncologic screening
- H. pylori not tested: test before treating with acupuncture
- Anemia: investigate intrinsic factor and B12
Frequently Asked Questions
Frequently Asked Questions
No. H. pylori is a bacterium that can only be eradicated with antibiotics (combined with a PPI). Acupuncture has no antibacterial activity. Its role is complementary: improving symptoms and supporting mucosal healing after eradication.
It depends on the clinical situation, and this decision must be individualized with the gastroenterologist. In symptomatic gastritis without active ulcer and with H. pylori already eradicated, acupuncture may be considered as a complementary option, allowing in some cases a discussion of gradual PPI reduction under medical supervision. In active ulcer or erosive esophagitis, the PPI is indispensable. Never discontinue or reduce medication on your own.
8 to 10 sessions over 4 to 5 weeks are usually sufficient for significant symptom improvement. More complex cases or those with mucosal atrophy may require longer cycles. Monthly maintenance sessions are recommended to prevent symptomatic recurrence.
In autoimmune gastritis, the atrophy of parietal cells is irreversible — acupuncture does not restore the production of intrinsic factor or hydrochloric acid. The benefit is symptomatic: reduction of functional epigastric pain and improvement in motility. Intramuscular vitamin B12 replacement must be maintained.
Yes, it may contribute. Acupuncture can modulate mucosal protection in patients who need to maintain NSAIDs (rheumatoid arthritis, cardiovascular disease); the proposed mechanism involves protective PGE2 and mucosal VEGF. It does not replace the PPI in cases of severe lesion; any dose adjustment must be individualized by the attending physician.
