Focal enterocolitis means that there is focal intestinal epithelial hyperplasia, which is less extensive than the lesion of general enterocolitis. Generalized enterocolitis refers to intestinal epithelial hyperplasia, which is the presence of epithelial cells of the small or large intestine in the gastric mucosa, and is one of the most common lesions of the gastric mucosa. Focal intestinal epithelialization means focal intestinal epithelial hyperplasia, and the scope of the lesion is smaller. Patients with intestinal epithelialization need to have standardized treatment, and if there is Helicobacter pylori infection, they need to have Helicobacter pylori eradication treatment and regular rechecks, because intestinal chemosis has the possibility of cancer and can be detected and treated as early as possible. Patients should develop good living habits and dietary habits in general, and should have three meals a day at regular intervals, avoiding too spicy, stimulating and too greasy food. If you have intestinal metaplasia, you need to go to the hospital as soon as possible, by the doctor according to the specific conditions, to formulate individualized diagnosis and treatment plan, so as not to delay the condition.
