Low platelets and raw red dots are due to thrombocytopenia with capillary bleeding, which is the most common clinical symptom of thrombocytopenia. For thrombocytopenia: First, we should reduce activities, stay in bed and avoid bruises, and also avoid eating hard food in diet to avoid damage to the digestive tract bleeding. Secondly, the cause of thrombocytopenia should be actively investigated, and a bone marrow aspiration is usually required. Clinically, the common diseases that cause thrombocytopenia include immune thrombocytopenic purpura, aplastic anemia, myelodysplastic syndrome, acute leukemia, etc. All of these diseases require bone marrow aspiration. After the diagnosis is confirmed by bone marrow aspiration, the corresponding treatment can be given. For example, patients with acute leukemia can be treated with platelet transfusion to improve bleeding and then given chemotherapy or hematopoietic stem cell transplantation. If the thrombocytopenia is caused by aplastic anemia, it is often necessary to first give blood and platelet transfusion treatment, and then give oral treatment with cyclosporine, Conilon and other drugs.
