(1) Acute gastritis in patients with acute gastritis is an acute and reversible gastric mucosal lesion, which can be caused by chemicals (tobacco, spirits, strong tea, coffee, drugs, etc.). ), body (too hot, too cold, too rough food, X-ray irradiation, etc. ) Irritation or contact with bacteria or their toxins. The course of disease is generally short, and it will get better in 1~2 days. Generally divided into simple, corrosive, infectious, suppurative and hemorrhagic erosive gastritis. Principles of diet health care for patients: ① Symptoms such as vomiting and diarrhea often appear in patients with acute phase. Due to more water loss, we should pay attention to supplement a lot of liquids in the diet, such as fresh fruit juice, lotus root powder, rice soup, egg soup, etc., and drink plenty of water to relieve dehydration and accelerate the excretion of toxins. ② After the illness is relieved, you can give semi-liquid food with less slag and gradually transition to soft rice with less slag. The diet should be non-irritating and low in fiber, such as rice porridge, lean rice porridge, egg porridge, boiled dried noodles, egg drops, noodle soup, steamed egg soup, and appropriate amount of dry steamed bread, dry bread, soda biscuits, salty bread, etc. (3) protein should be supplemented. Cooked lean meat or minced meat can be used to make meatballs or shredded pork, stewed fish slices, fish balls and so on. Improve the collective disease resistance. 4 In order to reduce the burden on the stomach, it is more appropriate to eat less and more meals, and it is more appropriate to eat 5 to 6 times a day. Cooking can be done by steaming, boiling and stewing to facilitate digestion and absorption. (2) Patients with chronic gastritis Chronic gastritis refers to inflammatory or atrophic lesions of gastric mucosa, which is a common disease. Modern medicine divides this disease into four types: chronic superficial gastritis, chronic atrophic gastritis, chronic erosive gastritis and chronic hypertrophic gastritis. It is generally believed that the pathogenic factors causing chronic gastritis are: persistent acute gastritis, bacterial infection, drug stimulation, improper diet, chronic nasopharyngeal and oral diseases, and gastric acid deficiency. Principles of diet health care treatment: ① Try to eliminate inducing factors. For example, thoroughly treat acute gastritis, avoid spicy and hard diet and drugs that are irritating to the stomach, and treat chronic infections of the mouth and throat. (2) Eat digestible and non-irritating foods, such as semi-liquid or less slag diet. (3) Eat more meals in small quantities, and avoid mechanically and chemically stimulated food and cold food. ④ Foods rich in protein and multivitamins should be supplied, such as animal liver, lean meat, eggs and fresh leafy vegetables. ⑤ Anyone with hyperacidity should avoid concentrated fresh soup such as concentrated chicken soup, acidic food and a lot of protein to avoid increasing gastric acid secretion. It is advisable to eat milk, soybean milk, cream, vegetable paste, porridge, noodles, bread, etc. Those with low gastric acid secretion can be given thick soup, thick fish soup, gravy and appropriate sweet and sour food to stimulate gastric acid secretion, help digestion and increase appetite.
