Suggestion: During chemotherapy, patients' loss of appetite and poor nutritional status will affect the therapeutic effect. A reasonable diet helps to maintain a nutritional balance. Drinking more water and cold drinks can relieve stomach discomfort. Choose high-calorie, high-protein, high-cellulose and digestible foods according to your hobbies, and avoid sweets, fried and high-fat diets. It is suggested to use traditional Chinese medicine at the same time to reduce the side effects of chemotherapy.
