Eosinophilic gastritis is caused by recurrent inflammation of gastric mucosa, and this inflammation of stomach can become gastric ulcer by further development. If treated actively, it usually does not become cancerous, but if it is not taken seriously and treated irregularly, the risk of cancer will keep increasing if the lesion is more than 5 years old, so giving correct treatment in time is the key to prevent cancer. Acute erosive gastritis is one of the main causes of gastrointestinal bleeding, and serious bleeding can even lead to death, so although erosive gastritis is not easily cancerous, the harm to our body cannot be ignored. The chance of carcinogenesis in erosive gastritis is very small, but if erosive gastritis has a long duration, is not treated regularly, and is accompanied by infection of Helicobacter pylori, it can cause atrophic gastritis, which has a greater risk of carcinogenesis. If we have abdominal pain, bloating, nausea, vomiting, acid reflux and other digestive discomfort symptoms, and gastroscopy diagnosed as erosive gastritis, we should pay enough attention and actively carry out early treatment. First of all, we must pay more attention to diet, eat less cold, spicy and stimulating food, it is recommended not to drink strong tea and coffee and other beverages, quit smoking and alcohol, avoid staying up late, and maintain regularity of life and rest. At the same time to actively give regular drug treatment, it is recommended that the triple therapy can be used and information. After a sufficient course of treatment, pay attention to review gastroscopy and closely monitor the condition.
