Acute gastritis is a sudden inflammation of the stomach's mucosal lining. Common causes include:

  • Alcohol consumption: Excessive intake or frequent, severe intoxication can irritate and damage stomach tissues.123
  • Ingestion of irritating substances: This includes the consumption of corrosive agents, such as acids or alkalies, which cause severe chemical gastritis.1
  • Infections: Bacterial or viral-induced inflammation of the gastrointestinal tract, known as gastroenteritis, is a frequent cause.2
  • Food poisoning: Ingesting contaminated food can trigger acute episodes.12
  • Medications: While prolonged use of NSAIDs and aspirin is typically associated with chronic gastritis and ulceration, the ingestion of certain irritating drugs can also contribute to acute gastric distress.124

These episodes are generally short-lived and typically subside rapidly with appropriate care, such as dietary adjustments or the discontinuation of the offending substance.12
