Gastritis

Excerpt

Gastritis is the inflammation of the gastric mucosa and is often used to describe the abnormal appearance of abnormal gastric mucosa on endoscopy or radiology. Gastritis encompasses infectious or immunological inflammation of the gastric mucosa and the host response. Histopathological evidence of inflammation in the stomach lining is essential to diagnose this condition. Gastropathy is a gastric mucosal disorder without inflammation, featuring epithelial injury and subsequent regeneration. Gastritis and gastropathy are not mutually exclusive conditions and might sometimes coexist. In clinical practice, gastritis may be accompanied by signs of mucosal injury, whereas gastropathy may present with an inflammatory reaction in the gastric mucosa.

Gastritis is classified based on the acuity of the condition (acute versus chronic), the histological features of inflammation, or the etiology. Although the categorization and classification of gastritis are not universally accepted, understanding the histological characteristics and etiological factors associated with the different types of gastritis is essential. Appropriate histological evaluation is also essential in devising management plans for this disease. The primary objective is to equip treating clinicians with the ability to improve patient outcomes through early intervention.
