What reason causes gastritis?

summary

There is a characteristic of chronic gastritis, that is, it does not heal for a long time. In many cases, it is often caused by fire, the pain is difficult to disappear, often blood stasis. In traditional Chinese medicine, it is said that the patient's collaterals have been for a long time. So what is the cause of gastritis?, Today I'd like to share this with you.

What reason causes gastritis?

First, the changes of immune factors and immune function have been paid attention to in the pathogenesis of chronic gastritis. Parietal cell antibodies can be found in the blood, gastric juice or atrophic mucosa of patients with atrophic gastritis, especially in patients with gastric body gastritis; It is suggested that autoimmune reaction may be the cause of some chronic gastritis. However, whether there are immune factors involved in the pathogenesis of gastritis remains to be determined. In addition, there was diffuse lymphocytic infiltration in the gastric mucosa of atrophic gastritis. In vitro lymphoblastic transformation test and leukocyte migration inhibition test were abnormal, suggesting that cellular immune response may have important significance in the occurrence of atrophic gastritis. Some autoimmune diseases, such as chronic thyroiditis, hypothyroidism or hyperthyroidism, insulin-dependent diabetes, chronic adrenocortical hypofunction, can be accompanied by chronic gastritis, suggesting that the disease may be related to immune response.

Second: long term use of irritating food and drugs, such as strong tea, liquor, spicy or salicylate drugs, or insufficient chewing when eating, repeated damage to gastric mucosa caused by rough food, or excessive smoking. Nicotinic acid directly acts on gastric mucosa.

Third: duodenal juice reflux study found that chronic gastritis patients with pyloric sphincter dysfunction, often cause bile reflux, may be an important pathogenic factor. Phospholipids in pancreatic juice, together with bile and pancreatic digestive enzymes, can dissolve mucus, destroy gastric mucosal barrier, and promote the anti diffusion of H + and pepsin into the mucosa, causing further damage. The chronic gastritis is mainly in the antrum. Gastritis caused by bile reflux is very common in patients with gastrojejunostomy. Peptic ulcer patients are almost accompanied by chronic gastric sinusitis, which may be related to the dysfunction of pyloric sphincter. Nicotine in tobacco can relax pyloric sphincter, so long-term smokers can promote bile reflux and cause gastric sinusitis.

matters needing attention

After treatment with antibiotics, the symptoms and histological changes can be improved or even disappeared. Therefore, it is suggested that this bacterium may be involved in the pathogenesis of chronic gastritis.
