Gastritis is a common digestive condition involving inflammation of the stomach lining. It can occur suddenly (acute gastritis) or develop over time (chronic gastritis) and affect individuals of all ages. This article delves into the causes, symptoms, diagnosis, and treatment options for gastritis, drawing on expert insights from gastroenterologists to comprehensively understand this condition.

What is Gastritis?

Gastritis refers to inflammation, irritation, or erosion of the stomach lining. The stomach lining contains glands that produce stomach acid and digestive enzymes. When this lining becomes inflamed or damaged, it can lead to various symptoms and discomfort.

Causes of Gastritis

Dr. Michael Schopis, an expert gastroenterologist at Manhattan Gastroenterology, explains, "Gastritis can be caused by several factors, including bacterial or viral infections, excessive alcohol consumption, chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs), stress, autoimmune disorders, and certain medical conditions like Crohn's disease."

  • Bacterial Infections: Helicobacter pylori (H. pylori) infection is a common cause of gastritis, particularly chronic gastritis. This bacterium can infect the stomach lining and lead to inflammation.
  • Medications: Prolonged use of NSAIDs (such as aspirin, and ibuprofen) or corticosteroids can irritate the stomach lining and contribute to gastritis.
  • Alcohol and Stress: Excessive alcohol consumption and chronic stress can weaken the stomach's protective lining, making it more susceptible to inflammation.
  • Autoimmune Disorders: In rare cases, the immune system may mistakenly attack the stomach lining, leading to autoimmune gastritis.
  • Other Factors: Other factors, such as bile reflux, radiation therapy, and certain infections, can also cause gastritis.

Symptoms of Gastritis

The symptoms of gastritis can vary depending on whether it is acute or chronic and the underlying cause. Common symptoms include:

  • Upper abdominal pain or discomfort
  • Nausea and vomiting
  • Bloating and feeling of fullness
  • Indigestion or heartburn
  • Loss of appetite
  • Dark stools (indicating bleeding)

Dr. Schopis emphasizes, "Some individuals with gastritis may experience no symptoms, while others may have severe discomfort. It's essential to consult a gastroenterologist if you experience persistent symptoms or notice changes in your digestive health."

Diagnosis and Treatment

Diagnosis of gastritis typically involves a combination of medical history, physical examination, and diagnostic tests:

  • Medical History: Your doctor will inquire about your symptoms, medical history, and any medications you are taking.
  • Physical Examination: A physical examination may reveal abdominal tenderness or bloating.
  • Diagnostic Tests: Tests such as blood tests (to check for H. pylori infection), stool tests, upper endoscopy (to visualize the stomach lining), and biopsy (to examine tissue samples) may be performed to confirm the diagnosis.

Treatment of gastritis aims to alleviate symptoms, promote healing of the stomach lining, and address the underlying cause:

  • Medications: Antacids, proton pump inhibitors (PPIs), and antibiotics (if H. pylori infection is present) may be prescribed to reduce stomach acid and treat infection.
  • Lifestyle Changes: Avoiding irritants such as alcohol, NSAIDs, and spicy foods can help prevent symptoms from worsening.
  • Dietary Modifications: Consuming a bland diet, eating smaller meals more frequently, and avoiding acidic or caffeinated beverages may alleviate symptoms.
  • Stress Management: Techniques such as relaxation exercises, meditation, or counseling can help reduce stress levels, which may exacerbate gastritis.


Gastritis is a common digestive condition characterized by inflammation of the stomach lining. Understanding its causes, symptoms, and treatment options is crucial for effectively managing this condition. If you experience persistent symptoms suggestive of gastritis, seek prompt evaluation and guidance from a gastroenterologist.
