Gastrointestinal System Disorders Q 230

Which of the following definitions best describes gastritis?
    A. Erosion of the gastric mucosa.
    B. Inflammation of a diverticulum.
    C. Inflammation of the gastric mucosa.
    D. Reflux of stomach acid into the esophagus.

Correct Answer: C. Inflammation of the gastric mucosa.

Gastritis is an inflammation of the gastric mucosa that may be acute (often resulting from exposure to local irritants) or chronic (associated with autoimmune infections or atrophic disorders of the stomach). The current classification of gastritis centers on time course (acute versus chronic), histological features, anatomic distribution, and underlying pathological mechanisms. Acute gastritis will evolve to chronic, if not treated.

Option A: Erosion of the mucosa results in ulceration. With peptic ulcers, there is usually a defect in the mucosa that extends to the muscularis mucosa. Once the protective superficial mucosal layer is damaged, the inner layers are susceptible to acidity. Further, the ability of the mucosal cells to secrete bicarbonate is compromised.
Option B: Inflammation of a diverticulum is called diverticulitis. Acute diverticulitis is inflammation due to micro-perforation of a diverticulum. The diverticulum is a sac-like protrusion of the colon wall. Diverticulitis can present in about 10% to 25% of patients with diverticulosis. Diverticulitis can be simple or uncomplicated and complicated.
Option D: Reflux of stomach acid is known as gastroesophageal disease. Gastroesophageal reflux disease (GERD) is a chronic gastrointestinal disorder characterized by the regurgitation of gastric contents into the esophagus. It is one of the most commonly diagnosed digestive disorders in the US with a prevalence of 20%, resulting in a significant economic burden in direct and indirect costs and adversely affects the quality of life.
