Gastritis patients should not eat plums, eating plums may aggravate the condition of gastritis patients. Gastritis patients usually have damaged gastric mucosa in the stomach, and eating plums will promote the secretion of gastric acid in the stomach, and the excessive gastric acid in the stomach will stimulate the already damaged gastric mucosa, leading to aggravation of the condition of gastritis patients. The diet of gastritis patients should be light and easy to digest, such as millet porridge, pumpkin porridge, egg custard, etc., and to avoid spicy and stimulating foods, such as chili peppers, wine, strong tea, etc., but also try to avoid acidic foods and fruits, etc.. At the same time, it should be noted that patients with gastritis should be treated with relevant medications when necessary, such as the use of acid-suppressing drugs such as omeprazole. Patients should go to the hospital for treatment in time when discomfort occurs to avoid delaying the condition.
