gastritis [gas-tri´tis] inflammation of the lining of the stomach. Gastritis is one of the most common stomach disorders, and occurs in acute, chronic, and toxic forms.acute gastritis severe gastritis that may be caused by intake of aspirin or other nonsteroidal antiinflammatory drugs, food poisoning, overeating, excessive intake of alcoholic beverages, or bacterial or viral infection; it is often accompanied by enteritis. The outstanding symptom is abdominal pain, and there is also a feeling of distention, with loss of appetite and nausea. There may be a slight fever and vomiting. The substance causing the irritation can often be identified, in which case it should be avoided. Treatment may include the use of antacids. A bland diet of liquids and easily digested food should be followed for 2 or 3 days. Simply prepared solid foods in small quantities can then be added.atrophic gastritis chronic gastritis with atrophy of the mucous membranes and glands.chronic gastritis gastritis that occurs repeatedly or continues over a period of time. Although pain, especially after eating, and symptoms associated with indigestion may occur in chronic gastritis, most patients are asymptomatic; however, the condition may lead to hemorrhage and ulcer formation. Among its possible causes are Helicobacter pylori, vitamin deficiencies, abnormalities of the gastric juice, ulcers, hiatus hernia, excessive use of alcohol, or a combination of any of these.
Chronic gastritis is treated with a bland diet; food should be taken frequently and in small amounts. Antacids or anticholinergics may also be used in moderation to minimize stomach acidity. If bleeding is a problem that cannot be controlled by conservative measures, partial gastrectomy, pyloroplasty, vagotomy, or total gastrectomy may be indicated.giant hypertrophic gastritis Ménétrier's disease.toxic gastritis gastritis resulting from ingestion of a corrosive substance such as a strong acid or poison. There is an acute burning sensation and cramping stomach pain, accompanied by diarrhea and vomiting; the vomit may be bloody. The victim may collapse. This condition is an emergency and immediate measures must be taken to prevent serious damage to the tissues of the stomach. First aid measures are begun at once to flush out and neutralize the poison.chronic gastritis A condition characterised by chronic inflammation of the gastric mucosa, which can be subdivided based on:
• Aetiology—e.g., Helicobacter pylori, bile reflux, NSAIDs, autoimmunity, allergic response, parasites (trongyloides spp, schistosomiasis, Diphyllobothrium latum); and
• Histopathological pattern.
Together, a diagnosis can be established (e.g., H pylori-associated multifocal atrophic gastritis) which guides management.chronic gastritis
