Gastric erosion occurs when the mucous membrane lining the stomach becomes inflamed. Specifically, the term "erosion" in this context means damage that is limited to the mucosa, which consists of three distinct layers: the epithelium (in the case of a healthy stomach, this is non-ciliated simple columnar epithelium), the basement membrane, and the lamina propria.
[1] [2] Complications may include stomach bleeding, stomach ulcers, and stomach tumors. [1] When due to autoimmune problems, low red blood cells due to not enough vitamin B12 may occur, a condition known as pernicious anemia. [3] Common causes include infection with Helicobacter pylori and use of nonsteroidal anti-inflammatory drugs . [1]
[4] [5] An ulcer in the stomach is called a gastric ulcer, while one in the first part of the intestines is a duodenal ulcer. The most common symptoms of a duodenal ulcer are waking at night with upper abdominal pain, and upper abdominal pain that improves with eating. [4] With a gastric ulcer, the pain may worsen with eating. [6]
Many stomach diseases are associated with infections. In the past it was widely but incorrectly believed that the highly acidic environment of the stomach would keep the stomach immune from infection. Many studies have indicated that most cases of stomach ulcers, gastritis, and stomach cancer are caused by Helicobacter pylori infection.
Peptic ulcers are most commonly caused by a bacterial Helicobacter pylori infection. [5] Epstein–Barr virus infection is another factor to induce gastric cancer. [6] [7] As well as peptic ulcers, vomiting blood may result from abnormal arteries or veins that have ruptured, including Dieulafoy's lesion and Gastric antral vascular ectasia.
For example, in about 10% of the American public, gastric or peptic ulcers can become a problem. Ulcers are sores that form in soft tissue, such as the lining of the digestive tract, and gastric ...
Infectious esophagitis cannot be spread. However, infections can be spread by those who have infectious esophagitis. Esophagitis can develop due to many causes. GERD is the most common cause of esophagitis because of the backflow of acid from the stomach, which can irritate the lining of the esophagus. Other causes include:
The duodenal bulb is the site of duodenal ulcer occurrence. Duodenal ulcers are more common than gastric ulcers and - unlike gastric ulcers - are caused by increased gastric acid secretion. Duodenal ulcers are commonly located anteriorly, and rarely posteriorly. Anterior ulcers can be complicated by perforation, while the posterior ones bleed.
