Omeprazole is a proton pump inhibitor that effectively inhibits gastric acid and protects the gastric mucosa. If it is a gastric disease with damage to the gastric mucosa, you can take omeprazole to relieve the symptoms. If the abdominal pain is caused by other diseases, such as enteritis or gastrointestinal dysfunction, the drug has no effect. In short, the use of drugs should be selected according to the cause of the disease and requires consultation with a medical professional and medical examination before use.
