Clinical InformationClinical

  • Gastritis

    inflammation of the gastric mucosa, a lesion observed in a number of unrelated disorders.

  • Gastritis, Atrophic

    gastritis with atrophy of the gastric mucosa, the gastric parietal cells, and the mucosal glands leading to achlorhydria. atrophic gastritis usually progresses from chronic gastritis.

  • Gastritis, Hypertrophic

    gastritis with hypertrophy of the gastric mucosa. it is characterized by giant gastric folds, diminished acid secretion, excessive mucus secretion, and hypoproteinemia. symptoms include vomiting; diarrhea; and weight loss.

  • Gastric Mucosa

    lining of the stomach, consisting of an inner epithelium, a middle lamina propria, and an outer muscularis mucosae. the surface cells produce mucus that protects the stomach from attack by digestive acid and enzymes. when the epithelium invaginates into the lamina propria at various region of the stomach (cardia; gastric fundus; and pylorus), different tubular gastric glands are formed. these glands consist of cells that secrete mucus, enzymes, hydrochloric acid, or hormones.

Patient EducationClinical

Gastrointestinal Bleeding

Your digestive or gastrointestinal (GI) tract includes the esophagus, stomach, small intestine, large intestine or colon, rectum, and anus. Bleeding can come from any of these areas. The amount of bleeding can be so small that only a lab test can find it.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
