Patients are relatively weak after chemotherapy and need to pay attention to the following problems: chemotherapy often leads to myelosuppression, i.e. chemotherapy drugs kill tumor cells and also have a killing effect on normal hematopoietic cells, which will lead to a decrease in white blood cells, red blood cells and platelets, and the decrease in white blood cells is easily complicated by infection, low red blood cells means anemia, and serious decrease in platelets will lead to bleeding. Therefore, it is necessary to review the blood routine every 3-5 days for half a month after chemotherapy to clarify whether there is bone marrow suppression, and to treat the abnormalities symptomatically. The gastrointestinal tract is also more fragile after chemotherapy, because chemotherapy drugs will cause loss of mucosa of the gastrointestinal tract, mucosa repair needs a period of time, generally about 20 days can be completely repaired, so yo this period of time, the diet is mainly easy to digest diet, and at the same time appropriate to increase nutrition. After chemotherapy to increase rest, avoid overwork, because after chemotherapy immunity is lower than usual, easy to catch a cold, more rest can improve immunity, but according to the situation can participate in the amount of labor, depending on the individual, some patients after chemotherapy is not too much influence, you can live and work normally. Maintain an optimistic mood and regular work and rest, because depressed and sad mood and irregular work and rest such as staying up late can reduce immunity, and low immunity will promote the growth of tumor cells. Return to the hospital for review and treatment on time, and seek medical consultation if there is any discomfort.
