Patients with chronic gastritis can exercise, but they should not engage in excessive physical activity. The main considerations for patients with chronic gastritis are dietary and medicinal precautions. In terms of diet, it is advisable to eat plenty of fresh vegetables and fruits rich in vitamins and to avoid foods that irritate the stomach, such as strong tea, coffee, and hard liquor. Regarding medication, it is important to avoid drugs that can damage the stomach lining, such as nonsteroidal anti-inflammatory drugs, antirheumatic drugs, and steroids. Additionally, patients with chronic gastritis should quit smoking. (Medication should be administered under the guidance of a professional doctor.)
