Gastritis — inflammation of the lining of the stomach clizistoy.
Clizistaya shell resists stomach irritation and can withstand the effect of a very strong acid. But for many reasons clizistoy irritation and inflammation of the stomach becomes possible.
Symptoms depend on the type of gastritis. Typically, for any form of gastritis characterized dyspepsia (pain, swelling and discomfort) in the upper abdomen.
Acute stress gastritis. Manifestations of the underlying disease, injury or burns usually override symptoms of the stomach, however, the patient may experience discomfort in the upper abdomen. Shortly after the injury clizistoy membrane of the stomach developed small hemorrhages, which in a few hours turn into ulcers. Ulcers and gastritis are, if a person recovers quickly from injury. However, if treatment is delayed, the ulcers enlarge and begin to bleed, usually occurs within 2-5 days after the injury. Blood gives feces black and viscous, liquid content of the stomach — red, and in severe cases, blood pressure begins to fall. The bleeding may be profuse, and lead to death.
Chronic erosive gastritis. Symptoms include mild nausea and pain in the upper abdomen. However, many patients, such as long-term users of aspirin, pain does not occur. Some people develop symptoms that resemble the plague, particularly pain in between meals. If gastritis leads to the formation of stomach ulcers and bleeding, symptoms include appearance of a black stool (melena), vomiting blood (gematomezis) or partially digested blood that looks like coffee grounds in appearance.
Eosinophilic gastritis. Abdominal pain and vomiting may be caused by the narrowing or obstruction (blockage) of the output from the stomach into the duodenum.
Menetries disease. The most common symptom is abdominal pain. Loss of appetite, nausea, vomiting and weight loss are less common, as well as bleeding from the stomach. Fluid retention and edema can be caused by protein loss from the inflamed clizistoy the stomach. This protein is mixed with the contents of the stomach and out of the body.
Plazmotsitarny gastritis. Abdominal pain and vomiting can be combined with the appearance of skin rash and diarrhea.
Gastritis as a result of radiation therapy is accompanied by pain, nausea, and heartburn due to inflammation, sometimes due to the development of gastric ulcers. If the wall is perforated ulcers of the stomach (gastric perforation), the content falls into the abdominal cavity, causing peritonitis (inflammation of the membrane clizistoy abdominal cavity) and severe pain. The result is a serious condition characterized by muscle tension doskoobraznym abdomen and requires urgent surgical intervention. In rare cases, after radiation output from the stomach is narrowed due to fibrosis, which causes abdominal pain and vomiting. Exposure can damage the protective lining of the stomach clizistuyu, so that the bacteria invade his wall, causing sudden severe gastritis, which is characterized by very severe pain.
Bacterial gastritis is usually caused by pyloric helicobacter infection (Helicobacter pylori). These bacteria live on the surface of the mucus-producing cells of the stomach clizistoy. No other bacteria in the acidic environment of the stomach does not grow healthy, but if the stomach does not produce enough acid in it can develop many other types of microorganisms. Bacteria in such abundance can cause acute or chronic gastritis.
Acute stress gastritis — the worst form of acute gastritis — cause sudden serious illness or injury, and not necessarily the stomach. Typical causes of this form of gastritis — extensive burns and injuries, accompanied by heavy bleeding.
Chronic erosive gastritis is caused by irritants such as drugs, especially aspirin and other nonsteroidal anti-inflammatory drugs, occurs in Crohn’s disease, bacterial and viral infections. This type of gastritis may be slow to develop in people who otherwise healthy, it is accompanied by bleeding or ulceration. Is more common in people who abuse alcohol.
Viral or fungal gastritis develops as a result of a prolonged illness, or damage to the immune system.
Eosinophilic gastritis is a result of allergic reactions to infection with worms. With this type of gastritis in the stomach wall accumulate eosinophils.
Atrophic Gastritis occurs when the lining of the stomach affect clizistuyu antibodies, causing its thinning and loss of many or all of the cells that produce acid. This condition is most common in older people, as well as in patients who deleted a portion of the stomach (gastrectomy). Atrophic gastritis can cause pernicious anemia, because this disease is disturbed absorption of vitamin B12 from food.
Menetries disease — a kind of gastritis, the reason is unknown. In this disease develop thick large folds of the stomach wall, lymph nodes, form a fluid-filled cyst. About 10% of people with the disease Menetries developing cancer of the stomach.
Plazmotsitarny gastritis — a form of gastritis, the cause of which is also unknown. In this disease in the wall of the stomach and other organs accumulate plasma cells (a type of white blood cells).
Ingestion of corrosive substances such as cleaning fluids, or active exposure to radiation, such as during radiotherapy can induce gastritis.
