Platelets have the functions of adhesion, aggregation of blood clots, release of pro-clotting factors, and contraction of blood clots, which can help the body to stop bleeding and facilitate wound healing. If platelets are low, some patients may have abnormalities such as anemia and poor blood clotting function. Therefore, when low platelets are found, it is important to go to the hospital in a timely manner and under the guidance of the doctor to conduct blood routine, coagulation and other related tests to clarify the cause and then treat the cause. Patients with low platelets can be treated in daily life in the following ways: 1. diet: it is advisable to eat a nutritious and easy-to-digest diet, with more fresh fruits and vegetables, and foods rich in iron and protein, such as spinach, animal offal, beef, mutton, milk, eggs, soy products, etc.; 2. medication: patients with low platelets can be treated with glucocorticoids under the guidance of a doctor. If the above treatment is not effective, glucocorticoids can be applied. If the above treatment is not effective, cyclophosphoglycoside can be used for treatment; 3, other methods: for patients with acute aplastic anemia, myelodysplastic syndrome, acute leukemia and other patients with severe reduction of platelets, there will be significant bleeding, platelet transfusion for treatment, if necessary, can also be taken to hematopoietic stem cell transplantation. In addition, for patients with secondary low platelets, conditioning should be based on finding the causative factors and relieving them. For example, if the platelet count is low due to trauma or infection, such conditions should be avoided as much as possible. If the low platelets are caused by drug factors or radiation damage, the drug should be discontinued or replaced and exposure to radiation should be avoided.
