The diagnosis of chronic gastritis is mainly based on gastroscopy and is divided into two types: chronic superficial gastritis and chronic atrophic gastritis. Superficial gastritis occurs mostly in young adults, and gastroscopy shows gastric mucosa congestion, edema or superficial erosion. The main symptoms are loss of appetite, upper abdominal distension and discomfort with pain, etc. In severe cases, it can cause gastric bleeding. There can also be no obvious symptoms, and stomach acid can be high, low or normal. Chronic atrophic gastritis mostly occurs after middle age and is characterized by loss of appetite, abdominal distention and vomiting, belching, nausea, weakness, malnutrition and anemia, and mostly reduced or lack of gastric acid. Atrophic gastritis accounts for about 10% to 20% of chronic gastritis. For the diagnosis of atrophic gastritis, it is difficult to detect with x-ray. Biopsies must be taken under the gastroscope and biopsy material must be observed under the microscope with glandular atrophy to confirm the diagnosis. It is generally believed that the incidence of carcinoma in severe chronic gastritis is about 3% to 5%. The etiology of chronic gastritis is not fully understood, but it is related to H. pylori infection, improper diet such as over-eating, inadequate chewing, food that is too rough, cold, hard, spicy, strong, long-term consumption of highly concentrated alcohol, excessive smoking, and taking drugs that are irritating to the stomach. In addition, incomplete treatment of acute gastritis, chronic diseases such as chronic infectious lesions of the oral cavity, nose and throat, etc., damage the gastric mucosa due to the stimulation of toxins and cause chronic gastritis. So, how should you prevent and control chronic gastritis? 1, to develop good eating habits, to do regular meals, avoid overeating. Avoid eating cold, hard, rough, smoky, fried and spicy irritating food. Chew and swallow slowly when eating, try to reduce the burden on the stomach and protect the gastric mucosa. Strictly prohibit smoking and alcohol, alcohol and tobacco is the enemy of damage to the gastric mucosa. Some statistics, about 10 cigarettes a day, 20% to 30% of people will get gastritis; more than 20 cigarettes a day, 40% of people will get gastritis. Wine stimulates the gastric mucosa even more than smoke. The incidence of gastritis can be as high as 60% if you drink 2 to 3 bottles of liquor a day, and about 80% of those who are addicted to alcohol suffer from gastritis. The actual fact is that you will be able to get a lot more than just a few of the most popular and most popular items. 3.Actively treat septic lesions in the mouth, nose and throat. 4, if the symptoms are obvious available drug treatment. If H. pylori is detected microscopically, it can be treated with antibacterial drugs under the guidance of a doctor. For epigastric pain, use atropine sulfate 0. 3 mg or probenecid 15 mg, taken 3 times a day. If the upper abdomen is full, belching, often vomiting acid or burning sensation in the upper abdomen, which is a manifestation of increased gastric acid, 1 or 2 kinds of acid-control drugs can be used, such as Gastrodin, calcium carbonate, magnesium oxide, raw gastrone, glutamine, mecamylamine, etc. If the stomach acid is too low and the appetite is poor, dilute hydrochloric acid combination can be taken orally to increase the secretion of stomach acid and promote digestion. Patients with anemia should enhance nutrition and eat foods rich in protein and iron, such as lean meat, animal offal, fish and shrimp, milk and eggs, soybean products, green leafy vegetables and black fungus, sesame paste, etc. 5. Exercise to strengthen physical fitness and improve gastrointestinal function. In addition, from the perspective of cancer prevention, patients suffering from chronic atrophic gastritis should undergo regular gastroscopy, preferably once a year. 6.Mood relaxation. Mental factors have a great impact on the function of the digestive system, depression, pessimism and disappointment, all day long, you do not want to eat and drink; emotional stability, openness and cheerfulness, mental health, happy mood is appetite. Therefore, maintaining an optimistic mood is very important for health.
