Chronic gastritis is a common and frequently-occurring disease in outpatient department of gastroenterology, including chronic superficial gastritis and chronic atrophic gastritis. Clinically, patients often have indigestion symptoms such as epigastric discomfort, dull pain, fullness, belching and anorexia. The occurrence of symptoms is often closely related to improper diet, weather changes and emotions, which leads to the above symptoms often appearing repeatedly and lingering. In daily life, patients with chronic gastritis should pay attention to the adjustment of diet, avoid eating spicy and irritating foods, avoid drinking alcohol, and avoid taking a large number of non-steroidal anti-inflammatory drugs such as aspirin and paracetamol for a long time. Most fruits that are often eaten in daily life will not aggravate the above dyspeptic symptoms, but some patients will aggravate the above symptoms after eating too sweet or too cold fruits. At the same time, patients should also pay attention to avoid eating irritating fruits such as lemons to prevent the symptoms from getting worse.
