When nausea and vomiting occur after esophageal cancer surgery, anti-emetic drugs can be given and dietary habits can be adjusted, which is often effective. Chemotherapy after esophageal cancer surgery can further reduce the probability of recurrence and metastasis. The most common adverse reaction of chemotherapy is nausea and vomiting. Dietary needs to give light liquid food or semi-fluid food, which can relieve the symptoms of patients, and if necessary, oral anti-emetic drugs can also relieve the symptoms significantly. Most of the digestive symptoms can be gradually adapted, so patients should not worry too much. If patients have serious vomiting, they need to take fluids to replenish energy. Therefore, although nausea and vomiting are relatively common in postoperative chemotherapy for esophageal cancer, they can get better treatment effect after active treatment.
