Chronic gastritis is a common gastrointestinal dysfunction disease, which is caused by many factors and can occur in men, women and children. But there are more male patients than female patients, and more elderly people than children. The onset time is long and it is easy to relapse. The incidence rate ranks first among all kinds of stomach diseases, and it is difficult to completely cure them. It lacks specific symptoms. Some patients will have different degrees of gastrointestinal adverse reactions, including fullness after meals, belching, nausea, abdominal tenderness and so on. In recent years, due to the fast pace of life, people have developed bad habits, resulting in unreasonable diet, immune dysfunction and more and more gastritis patients.

There are many causes of chronic gastritis, as follows: (1) Helicobacter pylori infection. Recent studies have shown that the most important inducing factor of chronic gastritis is Helicobacter pylori infection, and the metabolites of Helicobacter pylori neutralize gastric acid, thus damaging cells, releasing inflammatory mediators from epithelial cells, and finally appearing immune response. In addition, after acute gastritis, it turned into chronic superficial gastritis due to unhealed gastric mucosal lesions. (2) Irritating foods, such as long-term drinking and strong coffee, will destroy the protective barrier of human gastric mucosa, and then cause chronic gastritis. (3) Drug stimulation, some drugs including indomethacin and salicylate can cause chronic gastric mucosal damage. (4) Autoimmunity. Autoimmune response reduces the number of parietal cells and gastric acid secretion. (5) Bile reflux, bile salts in bile can destroy the gastric mucosal barrier, and distal digestive tract obstruction can cause reflux, thus causing chronic inflammation. (6) Environmental changes. When the environment and climate change, if it cannot be adapted in time, it is easy to make the nervous function of the stomach unbalanced and produce gastritis. (7) Other degenerative changes of gastric mucosa in the elderly will increase the infection rate of Helicobacter pylori; Long-term mental stress and irregular life; The decline of gastric mucosal repair function can easily lead to atrophy of gastric glands. Other pathological changes such as ulcerative colitis cause chronic gastritis.

Healthy diet is the key to prevent and treat chronic gastritis. Patients with chronic gastritis should pay attention to balanced nutrition. In their daily diet, light, digestible and less irritating foods should be given priority to. Food should contain plant protein, fat, vitamins, inorganic salts, sugars and so on. , including tofu, chicken, carrots, milk, fish and shrimp. Pay attention to the appropriate proportion to ensure adequate nutrition and prevent malnutrition. Pay attention to diet, eat less and eat more, chew slowly when eating, stimulate saliva secretion, avoid hot and cold spicy, avoid overeating, avoid alcohol and tobacco, and protect gastrointestinal mucosa. For patients with acute atrophic gastritis, we should choose semi-liquid food that is easy to digest and has no residue, avoid eating coarse grains, and take dietary fiber food in moderation to promote digestion and absorption and accelerate the repair of gastric mucosa. For patients with a small amount of bleeding, you can eat rice soup, potatoes and milk to help restore gastric mucosa. Patients with high gastric acid need to eat less foods that are easy to produce acid, avoid drinking original thick soup, and have a light diet. Give priority to cooking food to reduce gastric acid secretion and neutralize gastric acid with sugar-free and alkaline foods. For patients with hypochlorhydria, eat more sweet and sour food, thick juice, broth, hawthorn and so on. Stimulate gastric acid secretion and drink soup before meals to promote digestion. Patients with severe anemia symptoms should eat more fish, animal blood, lean meat and protein. Supplement heme iron and protein, pay attention to vitamin B and C, and choose fresh vegetables and fruits to promote iron absorption.

Keep warm. When the weather suddenly drops, cold air invades the abdomen and causes the stomach to contract, resulting in spasmodic pain, which in turn leads to nausea and vomiting. Therefore, when the weather turns cold, patients should pay attention to keep warm to prevent colds. When the patient's condition is not serious, he can exercise properly and combine work and rest to promote blood circulation and enhance physical strength. Avoid staying up late and fatigue, make yourself feel comfortable and pay attention to rest.

Gastropathy is a chronic disease, which needs long-term treatment and is easy to recur, and is closely related to personal eating habits. The implementation of diet health care for patients with chronic gastritis plays an important role in clinical treatment of chronic gastritis and prevention of seizures. Patients with chronic gastritis need to eat regularly and quantitatively, chew slowly, so as not to increase the digestive burden of the stomach. Patients also need to maintain a good mood, appropriate activities, and promote early recovery.
