What can be done about nausea during meals in late-stage kidney cancer?

For advanced kidney cancer patients experiencing nausea during meals, the following measures can be taken: 1. Nutritional support therapy: Provide high-calorie, easily digestible foods and oral nutritional supplements, which help maintain the patient's physical function and immune status, reduce weight loss, and promote recovery of physical strength. 2. Use of antiemetic drugs: Such as ondansetron and metoclopramide, which should be administered according to medical advice. These medications alleviate nausea and vomiting by acting on the central nervous system, improving the patient's comfort and promoting food intake. 3. Targeted treatment: Nausea may be caused by factors such as metastasis of advanced kidney cancer, side effects of chemotherapy drugs, kidney failure, gastrointestinal infection, or pyloric obstruction. Targeted treatments should be applied according to the specific cause, such as using sedative-hypnotic drugs, 5-hydroxytryptamine receptor antagonists, antibiotics, etc. The above measures should be selected and adjusted based on the patient's specific condition and the doctor's recommendations.
