Acute Gastritis: Causes, Symptoms, Diagnosis, and Treatment


Acute gastritis is a common condition characterized by inflammation of the stomach lining. It can lead to discomfort and digestive disturbances. In this article, we will explore the causes, symptoms, diagnosis, and treatment options for acute gastritis, shedding light on this temporary but potentially bothersome digestive issue.


Acute gastritis occurs when the protective lining of the stomach becomes inflamed. The condition can be sudden and short-lived or may last for a few days to weeks. It is often caused by irritants like alcohol, certain medications, or bacterial infections. Acute gastritis can be mild, causing minimal symptoms, or severe, leading to significant discomfort and digestive issues.


The symptoms of acute gastritis can vary and may include:

  • Abdominal pain or discomfort
  • Nausea and vomiting
  • Feeling full or bloated after eating
  • Loss of appetite
  • Indigestion
  • Belching


Acute gastritis can be caused by various factors, including:

  • Helicobacter pylori infection: A common bacterial infection that can irritate the stomach lining.
  • Nonsteroidal anti-inflammatory drugs (NSAIDs): Regular use of NSAIDs like aspirin, ibuprofen, or naproxen can lead to gastritis.
  • Alcohol consumption: Excessive alcohol intake can irritate the stomach lining.
  • Stress: Severe stress or trauma can trigger acute gastritis in some individuals.
  • Spicy or acidic foods: Consuming irritating foods can lead to gastritis in sensitive individuals.
  • Other infections: Viral or bacterial infections, such as from E. coli or Salmonella, can cause acute gastritis.


Diagnosing acute gastritis typically involves a combination of medical history, physical examination, and diagnostic tests, including:

  • Endoscopy: A flexible tube with a camera (endoscope) is inserted through the mouth to visualize the stomach lining and take biopsy samples if needed.
  • Blood tests: To check for signs of infection or inflammation.
  • Stool tests: To detect the presence of H. pylori or other infectious agents.


The treatment of acute gastritis focuses on relieving symptoms and addressing the underlying cause. Treatment may include:

  • Antacids: Over-the-counter antacids can help neutralize stomach acid and provide temporary relief.
  • Proton pump inhibitors (PPIs) or H2 blockers: These medications reduce stomach acid production and aid in healing the stomach lining.
  • Antibiotics: If H. pylori infection is detected, a combination of antibiotics may be prescribed to eradicate the bacteria.
  • Avoiding triggers: It's essential to avoid alcohol, irritating foods, and NSAIDs during the healing process.
  • Dietary changes: Consuming bland, easily digestible foods can ease discomfort.
  • Stress management: Practicing stress-relief techniques can be helpful in managing acute gastritis caused by stress.


Preventing acute gastritis involves adopting a few lifestyle measures, such as:

  • Avoiding excessive alcohol consumption
  • Using NSAIDs in moderation and only as directed
  • Eating a balanced diet and avoiding spicy or acidic foods if they trigger symptoms
  • Managing stress through relaxation techniques and healthy coping strategies


Acute gastritis is a common digestive issue caused by inflammation of the stomach lining. It can lead to discomfort and digestive disturbances. Fortunately, most cases resolve with proper treatment and lifestyle adjustments. If you experience symptoms of acute gastritis, consult with a healthcare provider for accurate diagnosis and personalized treatment to ensure a speedy recovery.
