Anatomy & Body Systems
Affected Body Systems
Primary Digestive Organs:
Stomach:
- Fundus - upper portion, responsible for initial mixing
- Body - main digestive region
- Antrum - lower portion, prepares food for intestine
- Pylorus - outlet to small intestine
Stomach Lining (Gastric Mucosa):
- Surface epithelial cells - produce mucus
- Parietal cells - produce hydrochloric acid
- Chief cells - produce pepsinogen
- G cells - produce gastrin hormone
Related Structures:
- Lower Esophageal Sphincter (LES) - controls entry from esophagus
- Pyloric Sphincter - controls exit to duodenum
- Duodenum - first part of small intestine
- Blood vessels supplying stomach
Physiological Process:
The stomach lining undergoes constant renewal, with cells replaced approximately every few days. Gastritis occurs when the balance between protective factors (mucus, bicarbonate, blood flow, cell renewal) and aggressive factors (acid, pepsin, NSAIDs, bacteria, alcohol) shifts toward damage.
The stomach is richly supplied by the autonomic nervous system:
- Vagus nerve (parasympathetic) - stimulates acid production
- Sympathetic nervous system - reduces blood flow during stress
- Enteric nervous system - "gut brain" controlling digestive function
This explains why stress and emotional factors significantly impact gastritis.
Types & Classifications
Primary Classification System
By Duration:
-
Acute Gastritis
- Sudden onset
- Often severe but short duration
- Commonly caused by NSAIDs, alcohol, stress, or H. pylori
- Usually resolves with treatment
-
Chronic Gastritis
- Gradual onset
- Long-lasting or recurring
- Often associated with H. pylori, autoimmune conditions, or long-term NSAID use
- May lead to complications if untreated
-
Acute on Chronic
- Chronic gastritis with acute flare
By Etiology:
| Type | Cause | Characteristics |
|---|---|---|
| H. pylori Gastritis | Bacterial infection | Most common cause worldwide; leads to chronic gastritis |
| NSAID-Induced | Medications | Erosive; risk increases with dose and duration |
| Stress-Related | Physical stress | Critical illness, surgery, burns |
| Alcoholic | Excessive alcohol | Direct chemical irritation |
| Autoimmune | Immune system attack | Affects body of stomach; associated with B12 deficiency |
| Biliary Reflux | Bile backflow | Chronic irritation from intestine contents |
| Radiation | Cancer treatment | Direct tissue damage |
By Histology:
- Superficial gastritis - inflammation limited to surface layer
- Interstitial gastritis - deeper tissue involvement
- Atrophic gastritis - thinning and cell loss
- Metaplastic gastritis - cellular changes
Causes & Root Factors
Helicobacter pylori (H. pylori) Infection: This spiral-shaped bacterium is the leading cause of chronic gastritis worldwide. H. pylori colonizes the stomach lining, surviving in the harsh acidic environment by producing urease (an enzyme that converts urea to ammonia, neutralizing acid around the bacteria). This triggers chronic inflammation and, if untreated, can lead to ulcers, atrophy, and even gastric cancer.
NSAID Use: Non-steroidal anti-inflammatory drugs (ibuprofen, naproxen, aspirin) are a major cause of gastritis. They work by inhibiting prostaglandins—chemicals that promote inflammation but also stimulate protective mucus production. Without this protective mucus, stomach acid damages the lining.
Excessive Alcohol Consumption: Alcohol is a direct irritant to the gastric mucosa. Chronic heavy drinking leads to inflammation, erosion, and impaired healing. The effect is dose-related, with higher consumption causing more severe damage.
Stress: Physical stress from serious illness, major surgery, burns, or trauma can cause "stress gastritis." This occurs through reduced blood flow to the stomach lining and increased acid production, combined with compromised mucosal defenses.
Autoimmune Conditions: In autoimmune gastritis, the immune system mistakenly attacks the parietal cells in the stomach lining. These cells produce intrinsic factor (needed for B12 absorption) and acid. This leads to chronic inflammation, pernicious anemia, and increased risk of gastric cancer.
Biliary Reflux: When bile flows backward from the small intestine into the stomach, it causes chemical irritation and inflammation. This can occur after gallbladder surgery or due to pyloric dysfunction.
Other Infections: While H. pylori is most common, other infections (cytomegalovirus in immunocompromised, herpes simplex, fungi) can cause gastritis in specific populations.
At Healers Clinic, we investigate gastritis through our "Cure from the Core" philosophy:
- H. pylori Status - Is this bacterial infection present?
- Medication Review - Are NSAIDs or other medications causing damage?
- Dietary Patterns - Are irritants in the diet?
- Stress Load - Is chronic stress affecting digestive function?
- Digestive Fire - Is there dysbiosis or impaired digestion (Ayurvedic perspective)?
- Nutritional Status - Are deficiencies impairing healing?
- Immune Function - Is autoimmunity involved?

Differential Diagnosis
Overview of Differential Diagnosis
Gastritis must be differentiated from other conditions causing similar symptoms:
| Condition | Key Distinguishing Features |
|---|---|
| Peptic Ulcer | Pain more localized, often at night, relieved by eating |
| GERD | Heartburn predominant, reflux symptoms |
| Gallbladder Disease | RUQ pain, after fatty meals, may radiate to scapula |
| Pancreatitis | Severe epigastric pain radiating to back, elevated enzymes |
| Gastric Cancer | Weight loss, persistent symptoms, older age |
| Functional Dyspepsia | No inflammatory changes, symptom-based diagnosis |
| Heart Attack | Often radiates to arm/jaw, associated with sweating |
Gastritis vs. Ulcer:
- Gastritis: diffuse discomfort, often improved with eating
- Ulcer: localized pain, may worsen with eating, night pain common
Gastritis vs. GERD:
- Gastritis: pain centered in stomach
- GERD: burning rises from stomach to chest/throat
Gastritis vs. Gallbladder:
- Gastritis: upper midline pain
- Gallbladder: right upper quadrant, after fatty foods

FAQ
Q: Is gastritis serious? A: While gastritis itself is usually not dangerous, it can lead to complications like ulcers, bleeding, or increased cancer risk if untreated. Proper evaluation and treatment is important.
Q: Can gastritis be cured completely? A: Yes, most cases of gastritis can be completely resolved, especially when the underlying cause (like H. pylori or NSAID use) is identified and addressed.
Q: What foods should I avoid with gastritis? A: Common triggers include spicy foods, citrus, tomatoes, fried foods, caffeine, alcohol, and carbonated beverages. However, triggers vary by individual.
Q: How long does it take for gastritis to heal? A: With appropriate treatment, acute gastritis typically improves within 1-2 weeks. Chronic gastritis may take several weeks to months to fully heal.
Q: Can stress cause gastritis? A: Yes, physical and emotional stress can contribute to gastritis by increasing acid production and reducing blood flow to the stomach lining.
Q: Do I need an endoscopy to diagnose gastritis? A: An endoscopy is the gold standard for diagnosing gastritis and allows direct visualization and biopsy. However, your doctor may recommend it based on symptoms and risk factors.
