What type of Peptic Ulcer is characterized by pain occurring immediately after eating?

The type of peptic ulcer characterized by pain occurring immediately after eating is a gastric ulcer. Gastric ulcers develop in the stomach lining and are often aggravated by the presence of food. When food enters the stomach, it stimulates gastric acid secretion, which can exacerbate the pain due to the ulcer's location. This is in contrast to duodenal ulcers, which typically cause pain a few hours after eating, as they are located in the duodenum and the pain often correlates with the emptying of the stomach.

Gastric ulcers can be associated with several factors, including the use of nonsteroidal anti-inflammatory drugs (NSAIDs), infection with Helicobacter pylori, or an increased production of gastric acid. Understanding the timing of the pain in relation to food intake is essential in differentiating between gastric and duodenal ulcers, aiding in the proper diagnosis and management of these conditions. Stress ulcers and chronic ulcers do not specifically align with the immediate pain after eating characteristic of gastric ulcers.
