Definition

What Is Gastritis?

Gastritis is inflammation of the stomach lining (mucosa). It can be acute (sudden, often resolves) or chronic (persistent, often progressive). The hallmark is breakdown of the protective mucus layer, allowing stomach acid to irritate or damage the underlying tissue.

~50% of gastritis cases are caused by Helicobacter pylori infection, a bacteria that colonizes ~50% of the world population (less in developed countries). Other major causes: NSAIDs (ibuprofen, aspirin), alcohol, severe stress (ICU patients), bile reflux, autoimmune attack on parietal cells (autoimmune atrophic gastritis), and viral infections.

Untreated chronic gastritis progresses through stages: chronic inflammation โ†’ atrophy โ†’ intestinal metaplasia โ†’ dysplasia โ†’ gastric cancer. This makes early identification and treatment of the root cause critical, particularly H. pylori eradication.

โš ๏ธ Chronic untreated gastritis is a precursor to gastric cancer. H. pylori is classified by WHO as a Class I carcinogen. Testing for H. pylori is essential in anyone with persistent dyspepsia, especially with family history of gastric cancer.

Types of Gastritis

๐ŸŒฑ Acute Gastritis

Sudden inflammation, often from NSAIDs, alcohol binge, severe stress, or food poisoning. Symptoms: burning epigastric pain, nausea, sometimes vomiting blood. Usually resolves with removal of the trigger plus mucosal healing support (DGL, slippery elm).

๐ŸŒ— Chronic H. pylori Gastritis

Most common type globally. H. pylori produces urease, which neutralizes stomach acid locally, allowing it to colonize the gastric mucosa. Often silent for years. Eradication (triple/quadruple therapy + mucosal support) is curative.

๐ŸŒ‘ Autoimmune Atrophic Gastritis

Immune system attacks parietal cells (acid producers) and intrinsic factor, leads to hypochlorhydria, B12 deficiency (pernicious anemia), and elevated gastric cancer risk. Associated with Hashimoto's, type 1 diabetes, vitiligo. Requires lifelong B12 supplementation.

Signs & Symptoms

Symptoms of Gastritis

Chronic gastritis is often silent. Acute gastritis usually announces itself loudly. Both warrant evaluation, silent chronic disease quietly progresses.

๐Ÿ”ฅ Local Gastric Symptoms

๐Ÿ”ฅ

Burning Epigastric Pain

Upper central abdominal burning or gnawing, often worse on an empty stomach OR after eating (varies by individual). Classic "stomach ache" felt below the breastbone. Eating sometimes relieves, sometimes worsens.

๐Ÿคข

Nausea & Loss of Appetite

Inflammation impairs gastric emptying and reduces appetite. Persistent nausea with no clear cause, especially in the morning, warrants H. pylori testing.

๐Ÿ’จ

Early Satiety & Bloating

Feeling full after just a few bites; persistent bloating after meals. Reflects impaired gastric motility from inflammation. Often misdiagnosed as functional dyspepsia.

๐ŸŒŠ

Acid Regurgitation

Burning sensation in chest or throat as stomach acid moves backward. Common when gastritis impairs the lower esophageal sphincter or alters gastric emptying.

๐Ÿšจ Systemic & Red Flag Signs

๐Ÿฉธ

Vomiting Blood or "Coffee Grounds"

Bright red blood OR dark "coffee-ground" appearance indicates active or recent gastric bleeding. MEDICAL EMERGENCY, seek immediate evaluation.

โšซ

Black, Tarry Stools (Melena)

Digested blood from upper GI bleeding turns stool black and sticky. EMERGENCY. Distinguish from iron supplements (which also darken stool but don't cause stickiness/smell).

๐Ÿชซ

Fatigue & Iron-Deficiency Anemia

Slow, chronic blood loss from inflamed gastric lining causes iron-deficiency anemia. Unexplained anemia, especially in adults, requires upper GI evaluation to rule out gastritis, ulcers, or cancer.

๐Ÿง 

B12 Deficiency Symptoms

Atrophic gastritis impairs intrinsic factor production, causing B12 deficiency. Symptoms: fatigue, neuropathy, glossitis (smooth/painful tongue), cognitive changes. Often misattributed to aging.

Diagnosis

How to Test for Gastritis

๐Ÿงช H. pylori Testing

๐Ÿ’จ Urea Breath Test (UBT)

Most accurate non-invasive test. Drink urea labeled with carbon-13, then breath into a bag. H. pylori's urease enzyme breaks it down, releasing labeled CO2. Detects active infection. Stop PPIs 2 weeks before for accurate results.

๐Ÿ’ฉ Stool Antigen Test

Detects H. pylori proteins in stool. Highly accurate, useful for diagnosis and confirming eradication. Also requires PPI hold of 2 weeks.

๐Ÿฉธ Blood Antibody Test

Detects past or current infection but cannot distinguish active from resolved. Less useful for diagnosis; not used for confirming eradication. Lowest accuracy of the three.

๐Ÿ”ฌ Direct Visualization & Workup

๐Ÿฉบ Upper Endoscopy (EGD) with Biopsy

Gold standard. Directly visualizes the gastric lining; biopsies confirm inflammation type, H. pylori, atrophy, intestinal metaplasia, or dysplasia. Indicated for persistent symptoms, red flag signs, or age >55.

๐Ÿงฌ Parietal Cell & Intrinsic Factor Antibodies

Confirms autoimmune atrophic gastritis. Positive in 90%+ of cases. Important because autoimmune gastritis requires lifelong B12 supplementation and increased cancer surveillance.

๐Ÿฉธ Gastrin Level

Elevated in atrophic gastritis (parietal cells gone โ†’ no acid โ†’ G-cells produce more gastrin trying to stimulate acid). Useful in workup of hypochlorhydria.

๐Ÿฉธ CBC, Iron Studies, B12, Folate

Detect downstream complications: iron deficiency from chronic blood loss, B12 deficiency from atrophic gastritis. Critical in chronic gastritis workup.

Treatment Comparison

Holistic vs. Conventional Treatment for Gastritis

๐ŸŒฟ HOLISTIC
๐Ÿ’Š CONVENTIONAL
๐ŸŒฟ

Holistic / Functional Approach

Mastic gum, DGL licorice, zinc-carnosine, mucosal healers, stress reduction, trigger elimination

H. pylori Eradication
Mastic gum + Matula Tea: 70-80% eradication in trials (vs 90% for antibiotic triple therapy, but no resistance issue)
Mucosal Healing
Zinc-carnosine + DGL + slippery elm: documented gastric mucosal regeneration in 4-8 weeks
Timeline
Symptom relief in 1-2 weeks; full healing 4-8 weeks
Advantage
Addresses ROOT cause + heals lining + avoids PPI long-term dependency and microbiome disruption
Full Holistic Protocol Includes
  • Mastic gum (Pistacia lentiscus) 500-1,000mg 2x/day for 4-8 weeks, RCT evidence of H. pylori inhibition and gastric mucosa healing
  • DGL Licorice (deglycyrrhizinated) 380-760mg chewed 20 min before meals, stimulates mucus production, soothes inflammation. Avoid regular licorice (raises BP).
  • Zinc-Carnosine 75mg 2x/day on empty stomach, stays in gastric mucosa, promotes healing. Polaprezinc form best studied.
  • Slippery elm + marshmallow root, demulcent herbs that coat and soothe gastric lining. Take 30 min before meals.
  • Eliminate triggers: NSAIDs (use acetaminophen or anti-inflammatory diet instead), alcohol, smoking, ultra-processed foods, excess coffee
  • S. boulardii + Lactobacillus reuteri, probiotics shown to reduce H. pylori burden and antibiotic side effects when combined with triple therapy
  • Vitamin C + Vitamin E, antioxidants concentrate in gastric mucosa, support healing and reduce oxidative damage
  • Stress reduction, chronic stress impairs gastric mucus production via cortisol effects on prostaglandins
  • Bone broth + collagen peptides, provide glutamine and proline for mucosal repair
  • Manuka honey (UMF 15+) 1 tsp 2-3x/day, antimicrobial against H. pylori, soothing for gastric lining
โœ… Important: For confirmed H. pylori, especially with family history of gastric cancer or significant mucosal damage, conventional triple/quadruple therapy is the most reliable eradication. Holistic approaches work best as ADJUNCT and for ongoing maintenance/mucosal healing.
Nutritional Strategy

Diet for Healing Gastritis

Gastritis diet has two phases: acute (anti-inflammatory, soothing, easy to digest) and maintenance (prevent recurrence). Avoid common pitfalls, even healthy foods can irritate inflamed gastric tissue.

โœ… Prioritize These:

๐Ÿฅฆ Cruciferous Vegetables

Broccoli sprouts (especially!) are rich in sulforaphane, which has been shown to inhibit H. pylori and reduce gastric inflammation. Eat well-cooked initially if raw irritates.

๐Ÿต Green Tea

EGCG and catechins inhibit H. pylori growth and reduce gastric inflammation. Drink 2-3 cups daily, not on completely empty stomach if it irritates.

๐Ÿฏ Manuka Honey (UMF 15+)

Methylglyoxal content inhibits H. pylori. 1 teaspoon 2-3x daily. Soothing and antimicrobial. Standard honey doesn't have the same effect.

๐Ÿฒ Bone Broth & Fermented Foods

Bone broth provides glutamine and collagen for mucosal repair. Fermented foods (sauerkraut, kefir if tolerated) support healing microbiome. Start small to avoid bloating.

โŒ Limit or Eliminate:

๐Ÿบ Alcohol

Direct irritant to gastric mucosa. Even moderate amounts impair healing. Eliminate completely during acute phase; minimize permanently if recurrent gastritis.

โ˜• Coffee & Acidic Drinks

Coffee stimulates acid production and is a direct irritant. Citrus juices and sodas are highly acidic. Limit during acute phase; gradually reintroduce as healing progresses.

๐ŸŒถ๏ธ Spicy & Fried Foods

Capsaicin, fried food fats, and processed seasonings irritate inflamed gastric tissue. Bland during acute phase; reintroduce gradually if tolerated.

๐Ÿ’Š NSAIDs (Major Trigger)

Ibuprofen, aspirin, naproxen damage gastric mucus layer. Single biggest avoidable cause of gastritis. Use acetaminophen for pain, or address inflammation through diet/curcumin instead.

Supplement Protocol

Evidence-Based Supplements for Gastritis

These supplements address H. pylori, mucosal healing, inflammation, and downstream nutrient deficiencies common in chronic gastritis.

SupplementMechanism & EvidenceSuggested DoseTimingNotes
Mastic Gum (Pistacia lentiscus)Resin from Greek mastic tree. RCTs show in vitro and in vivo H. pylori inhibition; case series document gastric mucosa healing. Doesn't develop bacterial resistance.500-1,000mg 2x/dayEmpty stomach (morning & before bed)Greek-sourced highest quality. 4-8 week course; can repeat.
DGL LicoriceDeglycyrrhizinated licorice stimulates mucus secretion and bicarbonate production. Strong evidence in functional dyspepsia, gastritis, peptic ulcer. No BP-raising effect (vs regular licorice).380-760mg chewable, 2-3x/day20 min before mealsMUST be chewable for action in stomach. Avoid regular licorice if hypertensive.
