Bone marrow suppression often occurs after chemotherapy for tumor patients, resulting in lowered white blood cells, lowered platelets and reduced red blood cells. There are several ways to quickly restore bone marrow hematopoietic function: First, from the aspect of medication, long-acting leukostatic drugs can be used. These long-acting leukostatic drugs can last for nearly a month or so and will not reduce white blood cells. You can play short-acting leukostatic drugs, shortage of leukostatic drugs will last about a week, you can take oral blood-generating Chinese medicine as well as western medicine. Secondly, mainly from the nutritional aspect, you can eat dates, pig liver, egg yolk, iron-rich food are good for blood production function. Third, to keep a happy mood, not too much psychological stress, because the bone marrow suppression is temporary, not permanent, when the chemotherapy is over the bone marrow function immediately restored.
