Chronic Non-Atrophic Antral Gastritis: Understanding the Condition and Its Management

Chronic non-atrophic antral gastritis is a type of long-term inflammation of the stomach lining, specifically affecting the antrum — the lower part of the stomach near the small intestine. This condition is classified as chronic because it persists for more than three months. Unlike atrophic gastritis, chronic non-atrophic gastritis does not involve significant intestinal metaplasia or dysplasia, which are key indicators of more severe gastric changes.

What Causes Chronic Non-Atrophic Antral Gastritis?

Several factors can contribute to the development of this condition, including long-term irritation from excessive alcohol consumption, regular use of nonsteroidal anti-inflammatory drugs (NSAIDs), or infection with Helicobacter pylori (H. pylori) bacteria. Autoimmune disorders and chronic bile reflux are also potential causes. Identifying the underlying cause is crucial for effective treatment and prevention of complications.

Symptoms and Diagnosis

Common symptoms of chronic non-atrophic antral gastritis include upper abdominal pain, nausea, bloating, and a feeling of fullness after eating. However, some individuals may experience no symptoms at all. Diagnosis typically involves endoscopy, during which a biopsy of the stomach lining is taken to confirm the type and severity of gastritis.

Importance of Early Intervention

Timely lifestyle and dietary modifications, along with appropriate medical treatment, can significantly improve outcomes for patients with this condition. Recommended lifestyle changes include avoiding irritants like alcohol and spicy foods, managing stress levels, and quitting smoking. Medications may include proton pump inhibitors (PPIs), H2 blockers, or antibiotics if H. pylori is present.

Potential Complications and Prognosis

If left untreated or poorly managed, chronic non-atrophic antral gastritis may progress to atrophic gastritis, increasing the risk of gastric cancer. Therefore, regular follow-up with a healthcare provider and adherence to treatment plans are essential. With proper care, most individuals can expect a favorable prognosis and a reduced risk of disease progression.
