1. Due to the unique cytotoxic effect of chemotherapeutic drugs, tumor patients will suffer different degrees of tissue and organ damage after chemotherapy. At first, the most common manifestations were gastrointestinal reactions, such as anorexia, nausea and vomiting, intractable vomiting, abdominal pain and diarrhea. Therefore, in order to alleviate such symptoms, we can drink more water during chemotherapy to facilitate the excretion of poisons and reduce the irritation to the gastrointestinal tract. At the same time, you can eat more foods that are less greasy, digestible and less irritating to supplement the vitamins needed by your body in time, and you can also use antiemetic drugs according to your doctor's advice.

2. Chemotherapy patients will show anxiety, depression, irritability and pessimism. Therefore, psychological encouragement and support should be given after chemotherapy, especially when patients are skeptical about the effect after treatment, they should patiently explain and encourage, relieve the pain caused by the patient's body in time, and establish a firm belief in overcoming the disease.

3. The toxic reaction of many chemotherapy drugs is also manifested in the damage to mucosa, especially stomatitis and oral erosion after repeated use of large doses. Faced with this situation, preventive measures should be taken in advance, such as: during chemotherapy, instructing patients to drink more water to reduce the irritation of chemotherapy drugs to oral mucosa; Rinse with mouthwash every day, 1 day 4 times; Especially when taking chemotherapy drugs orally, pay attention to wipe off the powder outside the capsule and drink water repeatedly after taking it.
