The choice of medication for intravenous therapy in acute gastritis focuses on suppressing gastric acid secretion, protecting the gastric mucosa, and the rational use of antibiotics. It is also important to replenish fluids and electrolytes to maintain sodium-water balance. During treatment, attention should be paid to regular eating habits, consuming more vegetables and fruits to add dietary fiber. Additionally, the main diet should consist of soft, easy-to-digest foods, such as millet porridge, rice soup, or vegetable soup; it is advisable to avoid raw, cold, spicy foods and to stay away from strong tea, coffee, and hard liquor to prevent damage to the gastric mucosa. Regular, timely meals should be adhered to, along with developing a regular routine of living habits. After recovery, appropriate outdoor exercises should be conducted to strengthen the physique and maintaining a positive mindset plays an active role in preventing gastrointestinal diseases.
