Abstract:
Pill-induced esophageal injury is a well described clinical entity. In contrast, pill-induced gastric injury has not been well characterized. In this report, we describe two patients with acute gastric ulcers due to pill ingestion and review the available literature on pill-induced gastric injury. The first patient presented with upper gastrointestinal hemorrhage and was found to have a large gastric ulcer with multiple potassium chloride pills in the ulcer crater. The second patient presented with odynophagia and endoscopy revealed doxycycline-induced esophageal and gastric injury. To our knowledge, this is the first case report of doxycycline-induced gastric ulcer.

Pathophysiology of Peptic Ulcer Disease: Injurious Factors
In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds to M3...

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
