Bruising when the leg is touched can be seen in thrombocytopenia, coagulation disorders, hereditary hemorrhagic trichotillomania or liver disease, etc. It is also seen in healthy women and the elderly.
1. Thrombocytopenia: seen in primary immune thrombocytopenia, acute leukemia, systemic lupus erythematosus, etc., due to thrombocytopenia, resulting in coagulation dysfunction, resulting in bleeding after hemostasis difficulties and other conditions. Its treatment needs to be based on the cause of the disease, including immunosuppressants, glucocorticoids and other drug therapy and radiotherapy.
2. Coagulation dysfunction: mainly seen in hemophilia patients, due to the lack of coagulation factors, resulting in various types of coagulation dysfunction, manifested as difficulty in stopping bleeding after minor bumps and bruises or spontaneous joint bleeding without obvious triggers, etc. The treatment is based on supplementing the lack of coagulation factors. The treatment is based on supplementing the lack of coagulation factors, and anti-fibrinolytic drugs such as desmopressin and aminocaproic acid can also be used for treatment.
3. Hereditary hemorrhagic capillary dilatation: it is a kind of autosomal dominant hereditary disease, and its commonly used therapeutic drugs include iron agents such as ferrous sulfate, hemostatic agents such as phenolsulfonyl ethylamine, and endothelial cell growth factor inhibitors such as thalidomide.
4. Liver diseases: such as liver cirrhosis, due to the decrease of coagulation factors caused by liver insufficiency, the phenomenon of subcutaneous bleeding is easy to occur.
5. Healthy women and the elderly: Some young women and the elderly, with higher blood vessel fragility, are more prone to rupture and bleeding than others, but all kinds of examinations do not show any abnormality. Generally, no treatment is needed, and it is enough to pay attention to avoid bumping in life.
The causes of the above symptoms are mainly platelet and coagulation function abnormalities. It is recommended to actively seek medical advice, improve the blood routine, coagulation function tests, etc., so as to make a clear diagnosis and carry out standardized treatment. Drugs should be used in accordance with medical advice.
