There is a clinical distinction between acute and chronic erosive gastritis. On the basis of the lesions of acute and chronic gastritis, single or multiple foci of erosion or erosions visible on the gastric mucosa are seen on gastroscopy and are among the more serious cases of gastric inflammation. Acute erosive gastritis may be life-threatening due to untreated acute erosive gastritis with underlying disease, while chronic erosive gastritis may develop into gastric cancer. However, patients do not need to worry too much, and active cooperation with treatment can achieve improved prognosis: 1. Acute erosive gastritis: If patients have symptoms such as vomiting blood, black stool, and dyspnea, it is considered that it may be caused by acute erosive gastritis. Patients should promptly seek medical attention and have a nasogastric tube placed under the guidance of a physician to perform gastric suction to remove retained gastric juice and bile from the stomach, thereby improving blood circulation to the stomach wall. In addition, patients should follow medical advice to use drugs such as omeprazole and esomeprazole to inhibit gastric acid secretion, as well as aluminum thioglycollate to protect the gastric mucosa. Some patients with large and uncontrollable gastric bleeding require surgical treatment; 2. Chronic erosive gastritis: clinically, symptomatic treatment with drugs is mostly used, commonly combined with proton pump inhibitors such as esomeprazole and omeprazole, antibiotic drugs such as metronidazole, tinidazole and clarithromycin, and bismuth potassium citrate to achieve the eradication of H. pylori. Patients should also use alkaline acid-control drugs such as sodium bicarbonate and aluminum hydroxide, or H2 receptor antagonists such as ranitidine and cimetidine, as prescribed by the doctor, to play a role in inhibiting gastric acid secretion. In addition, gastric mucosa-protective drugs such as aluminum thioglycollate and teprenone should be used for treatment under the guidance of a doctor. In addition to drug therapy, patients with chronic erosive gastritis can also be treated with physical therapy, including endoscopic argon coagulation and high frequency therapy.
