Quick Reference Facts
In simple words
Gastritis is defined as inflammation of the gastric mucosal lining confirmed histologically or endoscopically [D0008-KEYNOTES, CIT-0044]. It ranges from acute erosive hemorrhagic gastropathy to chronic Helicobacter pylori or autoimmune gastritis.
A histologically or endoscopically documented inflammatory mucosal breakdown of the stomach wall induced by bacterial infection, chemical irritants, or autoantibodies.
Common causes
- Helicobacter pylori bacterial colonization causing chronic antral or pangastritis [D0008-KEYNOTES, CIT-0044]
- Chronic nonsteroidal anti-inflammatory drug (NSAID) or aspirin use disrupting protective mucosal prostaglandins
- Excessive alcohol intake, heavy smoking, severe physiological stress (stress ulcers), or autoimmune parietal cell antibodies
Risk Factors
- Frequent or unmonitored use of NSAIDs, corticosteroids, or anticoagulants
- Untreated H. pylori infection, chronic alcohol ingestion, and high physiological stress
- Autoimmune conditions (e.g. Hashimoto's thyroiditis, Type 1 diabetes) predisposing to autoimmune gastritis
Common symptoms
- Epigastric gnawing or burning pain, early satiety, postprandial fullness, and nausea [D0008-KEYNOTES, CIT-0044]
- Abdominal distension, belching, regurgitation, and anorexia
- Erosive gastropathy symptoms: Occult blood loss, microcytic anemia, or hematemesis
Lifestyle & diet support
Avoid NSAIDs, alcohol, smoking, and highly spiced or greasy foods; eat small, regular meals; maintain adequate hydration; and manage chronic stress.
Treatment Approaches
Conventional Management
Management involves proton pump inhibitors (PPIs), H2-receptor antagonists, sucralfate mucosal protectants, discontinuing offending NSAIDs, and quad-therapy antibiotic regimens for H. pylori eradication [CIT-0044].
Homeopathic Approach
Homeopathic remedies (such as Nux Vomica, Arsenicum Album, Phosphorus, Lycopodium) act as supportive care to soothe burning epigastric discomfort, balance digestive acidity, and improve dietary tolerance alongside gastroenterological evaluation.
