For acute gastritis with vomiting, you can drink millet porridge, rice soup, or vegetable soup. These foods have the least irritation to the gastric mucosa and will not aggravate vomiting by irritating the stomach lining. Additionally, active medical treatment should be pursued, commonly involving protectors of the gastric mucosa, drugs that suppress gastric acid secretion, and antispasmodic analgesics. In daily life, it's also important to maintain a regular diet, eating three well-timed and measured meals, and avoiding raw, cold, spicy foods, as well as avoiding strong tea, coffee, and hard liquor that may harm the gastric mucosa. Ensure meals are eaten at consistent times without overeating. Regular patterns of rest and appropriate outdoor exercise can positively impact gastrointestinal health. (Medications should be used under the guidance of a doctor based on individual circumstances.)
