Understanding Acute Gastritis: Causes, Symptoms, and Treatment

Acute gastritis is a condition characterized by the sudden inflammation of the lining of the stomach. This inflammation can cause various uncomfortable symptoms and is typically short-term, often resolving with appropriate treatment and lifestyle adjustments. Understanding the causes, symptoms, and treatment options for acute gastritis is essential for managing and alleviating this common gastrointestinal issue.


  1. Irritants and Toxins:
    Acute gastritis is often triggered by the consumption of irritants such as alcohol, certain medications (e.g., NSAIDs, aspirin), spicy foods, and corrosive substances. These substances can irritate the stomach lining, leading to inflammation.
  2. Bacterial Infections:
    Infections caused by bacteria like Helicobacter pylori (H. pylori) can lead to acute gastritis. H. pylori is a common bacterium that can cause stomach infections and inflammation of the stomach lining.
  3. Stress and Trauma:
    Physical stress due to major surgery, traumatic injuries, severe burns, or critical illnesses can also cause acute gastritis.
  4. Autoimmune Disorders:
    In some cases, the body’s immune system mistakenly attacks the cells lining the stomach, resulting in gastritis.
  5. Excessive Gastric Acid Production:
    Overproduction of stomach acid, which may occur in conditions like gastroesophageal reflux disease (GERD), can contribute to acute gastritis.


  1. Upper Abdominal Discomfort:
    Individuals with acute gastritis often experience a gnawing or burning pain in the upper abdomen, typically between the chest and the navel.
  2. Nausea and Vomiting:
    Gastritis can cause feelings of nausea, and in some cases, individuals may vomit.
  3. Indigestion and Belching:
    Symptoms such as bloating, indigestion, and excessive belching may be present.
  4. Loss of Appetite:
    Gastritis can lead to a decreased appetite and a sense of fullness even after consuming a small amount of food.
  5. Blood in Vomit or Stool:
    Severe cases of gastritis may result in bloody vomit or dark, tarry stools, indicating possible bleeding in the digestive tract.
  6. Hematemesis:
    This refers to vomiting blood and is a serious symptom that requires immediate medical attention.


  1. Dietary Changes:
  • Avoiding spicy and irritating foods, alcohol, and caffeine to reduce irritation of the stomach lining.
  • Opting for a bland diet that includes easily digestible foods like rice, applesauce, bananas, and plain yogurt.
  1. Medications:
  • Antacids: Over-the-counter antacids can provide temporary relief by neutralizing stomach acid.
  • Proton Pump Inhibitors (PPIs) and H2 Blockers: These medications help reduce stomach acid production, promoting healing of the stomach lining.
  • Antibiotics: If the gastritis is caused by an H. pylori infection, a combination of antibiotics is used to eradicate the bacteria.
  1. Symptomatic Relief:
  • Using pain relievers, such as acetaminophen, for pain management, as NSAIDs can exacerbate gastritis.
  1. Rest and Stress Management:
  • Getting adequate rest to allow the body to heal and reduce stress levels, as stress can aggravate symptoms.
  1. Hydration:
  • Drinking plenty of fluids to stay hydrated and aid in the healing process.
  1. Medical Supervision:
  • Following up with a healthcare professional for monitoring and to adjust the treatment plan as needed.


Acute gastritis, though uncomfortable, is generally a temporary condition that can be effectively managed with dietary modifications, medications, and appropriate lifestyle changes. By understanding its causes, recognizing its symptoms, and seeking timely medical attention and treatment, individuals can recover and maintain a healthy digestive system, preventing further complications associated with acute gastritis.
