From the Guidelines
Mild chronic gastritis is a persistent, low-grade inflammation of the stomach lining that develops gradually over time, primarily caused by Helicobacter pylori bacterial infection, and its treatment involves addressing the underlying cause, such as antibiotic therapy, to reduce the risk of complications like ulcers, bleeding, or stomach cancer. This condition occurs when the protective layer of the stomach becomes damaged, allowing digestive acids to irritate the stomach tissue. Common causes include Helicobacter pylori bacterial infection, regular use of nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin or ibuprofen, excessive alcohol consumption, smoking, or autoimmune responses 1. Symptoms may include mild upper abdominal pain, nausea, bloating, indigestion, and occasional vomiting, though many people experience no symptoms at all.
Key Considerations
- The primary cause of mild chronic gastritis is Helicobacter pylori infection, which can lead to more severe conditions like peptic ulcers and gastric cancer if left untreated 1.
- Treatment typically involves addressing the underlying cause, such as antibiotic therapy for H. pylori infection, usually a combination of amoxicillin and clarithromycin, plus a proton pump inhibitor like omeprazole for 7-14 days 1.
- Acid-reducing medications like proton pump inhibitors or H2 blockers may be prescribed to reduce stomach acid and allow healing.
- Lifestyle modifications are also important, including avoiding irritants like alcohol, tobacco, spicy foods, and NSAIDs.
Management and Prevention
- Early diagnosis and treatment of H. pylori infection can prevent the progression of gastritis to more severe conditions like gastric cancer 1.
- Screening for H. pylori infection is recommended in high-risk populations, such as those with a family history of gastric cancer or individuals from regions with high prevalence of H. pylori infection 1.
- Eradication of H. pylori infection can be achieved through antibiotic therapy, and it is essential to follow the recommended treatment guidelines to ensure effective eradication and prevent antibiotic resistance 1.

From the Research
Definition of Mild Chronic Gastritis
Mild chronic gastritis refers to a long-lasting inflammation of the stomach, which can be asymptomatic and may not cause significant symptoms 2. It is characterized by histological changes in the gastric mucosa, which can lead to a loss of appropriate gastric glands 3.
Causes of Mild Chronic Gastritis
The main cause of mild chronic gastritis is infection with Helicobacter pylori (H. pylori), a bacterium that can survive in the hostile environment of the stomach and cause inflammatory changes 3, 4, 5. Other factors, such as environmental factors, bacterial strain, host responses, and gastric mucosal microbiome dysbiosis, can also contribute to the development of chronic gastritis 3.
Characteristics of Mild Chronic Gastritis
Mild chronic gastritis can be characterized by:
- Inflammation of the gastric mucosa, which can lead to structural changes 3
- Presence of H. pylori, which can cause epithelial damage and activate the inflammatory process 2, 5
- Asymptomatic or mild symptoms, which can make diagnosis challenging 2, 6
- Increased risk of malignancy, particularly gastric cancer, which is biologically linked to H. pylori infection 3, 4
Types of Chronic Gastritis
There are different types of chronic gastritis, including:
- Gastritis A, which is confined to the proximal stomach and is caused by an autoimmune process 4
- Gastritis B, which is caused by H. pylori infection and is associated with peptic ulcer disease 4, 5
- Gastritis C, which is caused by drugs, alcohol, or biliary reflux and is often found in gastric remnants after partial resection 4
