The treatment of mild atypical hyperplasia of gastric epithelium includes dietary management, anti-Helicobacter pylori treatment, omeprazole to inhibit gastric acid secretion, and aluminum phosphate gel to protect gastric mucosa. 1. Dietary treatment: Chew and swallow slowly to reduce the stimulation of the stomach; avoid eating foods that are too hard, too acidic, too hot and too spicy; abstain from drinking alcohol and avoid drinking strong tea and coffee; and eat less salty, processed and pickled foods. 2. Anti-causal treatment:Those who have Helicobacter pylori infection should be treated with anti-Helicobacter pylori therapy, commonly used 1 proton pump inhibitor, 2 antibiotics, 1 bismuth agent, such as omeprazole, amoxicillin, clarithromycin, bismuth citrate potassium combination therapy. The use of aspirin, ibuprofen and other non-steroidal anti-inflammatory drugs leading to mild atypical hyperplasia of the gastric glandular epithelium should be discontinued. 3. Symptomatic treatment: Omeprazole inhibits gastric acid secretion and relieves pain; aluminum phosphate gel protects gastric mucosa; domperidone and mosapride improve bloating symptoms and promote gastrointestinal peristalsis; digestive enzymes relieve dyspepsia symptoms and flatulence.
