A bruise on the body indicates a subcutaneous bleeding condition, because after bleeding, red blood cells leak from inside the blood vessels to outside the vessels, which can cause bruising on the body. Treatment of bruises: First, the cause of the bruise should be clarified. If the bruising is caused by trauma, you can take bruising medicine, such as Panax notoginseng tablets. If the bruising is caused by thrombocytopenia, the most effective way is to take glucocorticoids to increase the number of platelets in the peripheral blood. After the platelet count is increased, the hemostatic function will be enhanced and the bruises will improve. If the bruising is caused by vitamin C deficiency, you can take vitamin C treatment. After vitamin C supplementation, the density of capillaries increases and permeability decreases, bleeding will be reduced and bruising will gradually improve. Therefore, when bruises appear on the body, different treatments should be given for different causes.
