The role of food to supplement platelets is very limited, it is recommended to treat the etiology according to the degree of low platelets. 1. If the patient’s platelets are mildly lowered, in a stable state, the risk of bleeding is low, the patient can be appropriate through the way of dietary supplementation, supplemental nutrition, improve immunity, accelerate the recovery of platelets, but the role of food is limited. 2. Etiological treatment is more important, such as aplastic anemia patients need to be given cyclosporine orally, for patients with very low platelet counts or patients with high risk of bleeding, platelet transfusion should be carried out to rapidly increase the number of platelets in the blood and reduce the risk of bleeding. It is recommended to identify the cause and define the treatment plan under the guidance of physicians, and the recovery of platelets through dietary supplements alone will have little effect.
