Why are gastric ulcers more common along the lesser curve near the pylorus of the stomach?

pylorus is a gram-negative bacillus that is found within the gastric epithelial cells. This bacterium is responsible for 90\% of duodenal ulcers and 70\% to 90\% of gastric ulcers. H. pylori infection is more prevalent among those with lower socioeconomic status and is commonly acquired during childhood.

Which region of the simple stomach is most prone to gastric ulcers?

Ulcers most commonly occur in the first part of the small intestine below the stomach (duodenum) and can also occur at the lower end of the esophagus or in the stomach. Most ulcers result from infection with Helicobacter pylori (H. pylori) bacteria.

What is the most common location of gastric ulcers?

Gastric ulcers are most frequently seen on the lesser curve of the stomach at the junction of the body and antrum. Acute stress ulcer involves the body of the stomach and is often multifocal and transient.

Why duodenum is the most common site of ulcer?

The main cause of this damage is infection with bacteria called Helicobacter pylori, or H. pylori. The bacteria can cause the lining of your duodenum to become inflamed and an ulcer can form. Some medications can also cause a duodenal ulcer, particularly anti-inflammatory drugs such as ibuprofen and aspirin.

What is the major difference between gastric and duodenal ulcers quizlet?

Gastric and duodenal ulcers are peptic ulcers, which are open sores in the lining of the digestive tract. Gastric ulcers form in the lining of the stomach. Duodenal ulcers develop in the lining of the duodenum, which is the upper part of the small intestine.

How do duodenal ulcers differ from gastric ulcers?

A peptic ulcer is a sore on the lining of your stomach or the first part of your small intestine (duodenum). If the ulcer is in your stomach, it is called a gastric ulcer. If the ulcer is in your duodenum, it is called a duodenal ulcer.

Which of the following is a risk factor of a peptic ulcer?

H. pylori infection is the most common risk factor for getting peptic ulcer disease.

What causes ulcers in the stomach?

Stomach ulcers are usually caused by Helicobacter pylori (H. pylori) bacteria or non-steroidal anti-inflammatory drugs (NSAIDs). These can break down the stomach’s defence against the acid it produces to digest food, allowing the stomach lining to become damaged and an ulcer to form.

Which is more common duodenal or gastric ulcer?

Gastric ulcers are most frequent among those aged 40–70 years, whereas duodenal ulcers are most commonly seen between the age of 25 and 55 years. Thus, complications in gastric ulcers tend to be more severe because they tend to affect older individuals.

What is the difference between gastric and duodenal ulcer?

Ulcers. A peptic ulcer is a sore on the lining of your stomach, small intestine or esophagus. A peptic ulcer in the stomach is called a gastric ulcer. A duodenal ulcer is a peptic ulcer that develops in the first part of the small intestine (duodenum).

What is pathophysiology of duodenal ulcer?

Although the pathophysiology of gastric ulcer and duodenal ulcer is similar, there are clearly differences between the two groups. Duodenal ulcer is typified by H. pylori infection and duodenitis and in many cases impaired duodenal bicarbonate secretion in the face of moderate increases in acid and peptic activity.
