The bruises on the body are also not bumped, which may be caused by abnormal blood vessels of the body, abnormal platelets, vitamin C deficiency, immune dysfunction and other factors. It is recommended to go to the hospital in time, under the guidance of the doctor for blood routine, coagulation elephant and other examinations, to clarify the cause, and then treat the cause. 1, vascular abnormalities: If the blood vessels are brittle, when the subcutaneous capillaries occur spontaneous rupture bleeding, then the body may appear bruises, can be under the guidance of the doctor to supplement vitamin treatment; 2, platelet abnormalities: For example, thrombocytopenia or platelet function 2. Platelet abnormalities: for example, platelet reduction or platelet function abnormalities may also occur in the case of bruising without bumping. If the bruising is caused by platelet reduction, the patient may have bleeding gums and scattered bleeding spots all over the body. In patients with abnormal platelet function, bruising may be accompanied by skin purpura, nosebleeds, and internal bleeding. In case of primary thrombocytopenia, glucocorticoids, such as prednisone and dexamethasone, may be used under medical supervision. For patients with particularly low platelets and at risk of bleeding, treatment with intravenous gammaglobulin infusion and, if necessary, cyclophosphamide or hematopoietic stem cell transplantation may be an option. For patients with abnormal platelet function, if bleeding symptoms appear, intravenous platelet suspension can be inputted for treatment under the guidance of doctors; 3. Vitamin C deficiency: if patients lack vitamin C, bruises may also appear on the body, which can be accompanied by fatigue, weakness, repeated gum bleeding and other symptoms, which can be treated with vitamin C supplementation under the guidance of doctors; 4.

If purpura is the cause, the etiology can be clarified and treated under the guidance of a doctor. At the same time, medication to improve capillary fragility, such as folic acid and creatinine, can be applied, and if necessary, intravenous infusion of platelet suspension can be used for treatment. If it is caused by blood system diseases, the cause should be identified and then treated for the cause.
