What are the reasons for easily developing bruises on the body?

The tendency of bruises on the body may be related to telangiectasia, and drugs, chemicals, and infections may all cause bruises on the skin. Abnormalities in platelets or coagulation function, as well as severe liver disease, may all contribute to this condition, which poses a significant hazard and requires prompt blood routine and coagulation function tests.

1. Abnormalities in vascular structure and function, such as hereditary hemorrhagic telangiectasia, infections, chemicals, and drugs.

2. Abnormalities in platelets. This includes thrombocytopenia, primary thrombocytopenic purpura, leukemia, aplastic anemia, as well as normal platelet count but dysfunctional platelets due to conditions like thrombocytopathy, uremia, or platelet dysfunction caused by infection.

3. Abnormalities in coagulation function, specifically coagulation factors, such as hemophilia, vitamin K1 deficiency, and severe liver disease.

If you tend to bruise easily, first conduct blood tests to check blood routine and coagulation function to rule out subcutaneous bleeding caused by abnormal platelets or coagulation function. If both are normal, consider that external force may have caused capillary rupture and bleeding, leading to purpura or ecchymosis. In such cases, no special treatment is required, and you can appropriately take vitamin C and vitamin E orally to avoid injury.
