Thrombocytopenia needs to identify the cause of the disease and treat the cause in order to have a good effect. In terms of diet, a healthy and balanced diet is sufficient. Clinically, low platelet count is common in hematologic diseases, such as aplastic anemia, leukemia and so on. It is necessary to treat the primary disease. For aplastic anemia, immunosuppressants, androgens and other drugs can be used to treat it, and severe cases need hematopoietic stem cell transplantation. With active and effective treatment, most people’s low platelet count will be relieved. When platelets are severely reduced, treatments such as platelet transfusions can be given to improve the situation. For drug-induced myelosuppression, pro-thrombogenic drugs such as Eltrombopag can be used. In terms of diet, people with thrombocytopenia can take protein-rich and vitamin-rich foods and avoid spicy and irritating foods.
