Nausea and vomiting during chemotherapy are common side effects after treatment. The main management strategies include dietary adjustments and medication therapy.

1. Reasonable dietary planning: If vomiting occurs after chemotherapy, maintain a light and easily digestible diet. Consuming foods that nourish the stomach, such as milk, pumpkin, noodles, and rice porridge, can help alleviate symptoms.

2. Medication Treatment: Antiemetic medications such as ondansetron and metoclopramide can be taken to alleviate symptoms by stopping vomiting and suppressing gastric acid secretion.

During, before, and after chemotherapy, patients should maintain a light diet and avoid spicy, stimulating, and greasy foods. Increasing intake of fruits and vegetables high in vitamins can effectively enhance the body's resistance and improve appetite.

Medication should be taken strictly as prescribed by a doctor. Do not self-medicate.
