Comprehensive Guide to Gastritis: Causes, Types, and Prevention

The stomach plays vital roles such as storing food, producing digestive enzymes, and transferring nutrients to the small intestine. However, various stomach issues can impair these functions. Conditions like gastritis, GERD, peptic ulcers, viral gastroenteritis, hiatal hernia, gastroparesis, and stomach cancer can cause significant discomfort and require prompt medical care.

Understanding Gastritis

Gastritis is a widespread condition affecting roughly 25-35% of individuals. It manifests in two forms: acute, characterized by sudden inflammation often caused by injury, infections, stress, or irritants like alcohol and NSAIDs; and chronic, which develops gradually due to bacterial infections, alcohol, certain medications, or immune problems. Symptoms include indigestion, nausea, loss of appetite, abdominal pain, and sometimes blood in vomit or stools.

Chronic gastritis can be classified into three types: type A (immune-related), type B (linked to Helicobacter pylori bacteria), and type C (caused by irritants such as bile or NSAIDs). Proper diagnosis involves medical history assessment and tests like H. pylori detection, endoscopy with biopsy, and X-rays. Prevention includes avoiding smoking, limiting alcohol, and managing dietary triggers like spicy or fatty foods. Early consultation with a healthcare provider is essential for effective management and avoiding complications.
