There is no specific time for the rise of low platelet count after chemotherapy, and it is related to the use of platelet-raising drugs after chemotherapy, liver function and nutritional status.
1. The use of platelet-raising drugs: after chemotherapy, platelet decrease, if actively use platelet-raising drugs, such as thrombopoietin, platelet count will rise in about a week.
2. Liver function: chemotherapy will lead to impaired liver function, and thrombopoietin, which stimulates platelet production, is synthesized by the liver, so the platelet rise time will be prolonged.
3. Nutritional status: Inadequate intake of protein, energy and other nutrients after chemotherapy will also affect platelet production, resulting in delayed platelet rise.
Severe platelet drop after chemotherapy, and there is no rising trend, should consult a doctor in time to clarify the cause of targeted treatment.
