![]() (rarely) symptoms in the limbs such as numbness or tingling.Deficiency of vitamin B12 eventually leads to a condition called pernicious anemia. This may cause digestive upsets.Īlso lost is the ability to secrete a substance called intrinsic factor, which is necessary for absorption of the important vitamin, B12. When the damage to the mucosa is severe and long standing, the stomach loses its ability to produce acid. In the vast majority of cases, chronic gastritis causes no symptoms. What are the symptoms of gastritis? Acute Gastritis SymptomsĪcute gastritis usually does cause an acute upset stomach, with upper abdominal pain or discomfort as the body tries to get rid of the irritant. gastric surgeries which increase the stomach's exposure to bile.Other causes of chronic gastritis may include: The infection rate of adults in underdeveloped countries may be as high as 90%. pylori infection is present in about 20% of Caucasians, but in over 50% of Hispanics, African Americans, and the elderly. Causes of Chronic GastritisĬhronic gastritis usually results from infection with helicobacter pylori (or H. pylori infection can increase the risks of developing stomach cancer, gastritis and/or peptic ulcers. In fact, it is suggested that more than half the world's population has this bacteria, yet never experience any problems. pylori) is one of many bacteria that is commonly found inside the stomach. Usually, the inflammation settles quickly when the irritant is removed. Irritants include aspirin or other NSAIDs (non-steroidal anti-inflammatory drugs), poisons (including strong alcohol) and certain infections, including the early stages of infection with the bacterium helicobacter pylori. What causes gastritis? Causes of Acute GastritisĪcute gastritis is caused by acute irritants that overwhelm the mucus lining that usually protects the stomach mucosa. When present for many years, the mucosal changes may progress to a stage called metaplasia, with a small increased risk of gastric cancer. This is very common, especially in less developed countries. The inflammatory cells include lymphocytes, which indicate an immune response. The gastric mucosa becomes thinner as the normal cells are destroyed. What is Chronic Gastritis?Ĭhronic gastritis refers to a persistent, but low grade, inflammation and damage to the stomach lining. There may be small, shallow breaks in the surface lining, called acute erosions ("erosive gastritis"), and even tiny areas of bleeding. When a gastroenterologist performs an endoscopy, the lining appears reddened, and specimens show lots of acute inflammatory cells (mainly white blood cells, called leucocytes). What is Acute Gastritis?Īcute gastritis refers to a sudden onset of inflammation of the stomach lining, called the gastric mucosa. There are two types of gastritis, acute and chronic. And it may sound odd to say, but in the true use of the term, "gastritis" -at least the chronic type (see below)- usually does not cause episodes of indigestion. However, strictly speaking, gastritis is a formal medical term for a diagnosis made by a pathologist when evidence of inflammation and damage to the stomach lining is seen in a biopsy specimen taken during an upper endoscopy. We refer also to “upset stomach” or “indigestion”. Gastritis is a term commonly used by the public (and sometimes by doctors) to describe episodes of stomach discomfort (usually after eating) sometimes associated with nausea and/or vomiting.
