Overview
1. The causes include physiological, pharmaceutical and disease -based factors
2. The pathogenesis is related to hemostasis or coagulation dysfunctional dysfunction.
3. It is often accompanied by anemia and fever caused by blood system diseases
4. Diagnostic relying on medical history, symptoms, clinical manifestations and auxiliary examinations

What is subcutaneous bleeding?
The subcutaneous small hemorrhoidal damage, decreased blood vessel elasticity, body stop bleeding or coagulation dysfunction can cause subcutaneous stasis, purpura, ecchymia or hematomy such as hematopoietic, that is, subcutaneous hemorrhage.

What are the types of subcutaneous bleeding?
Based on subcutaneous hemorrhage diameter and its accompanying situation, it can be divided into:
1. Small than 2mm is called a stasis point;
2.3 ~ 5mm called purpura;
3. greater than 5mm called ecchymia;
4. Licot bleeding and accompanied by a significant bulge called hematoma.
Depending on the cause, it is divided into physiological, vascular, drug -based factors, certain systemic diseases and subcutaneous hemorrhage.

How does subcutaneous bleeding appear?
When the subcutaneous small blood vessels are squeezed and injured, and the function of the vascular wall function is abnormal caused by various reasons, it cannot be contracted normally to stop bleeding, or there are platelets and coagulation dysfunction. Causes subcutaneous hemorrhage symptoms.

Reason
The causes of subcutaneous hemorrhage include physiological, vascular, drug -based factors, certain systemic diseases and blood system diseases. If there is no intention of bumping in daily life, the subcutaneous small blood vessels are squeezed and damaged; the elderly have decreased due to vascular elasticity; women's menstrual period and taking certain drugs will cause normal coagulation of the body to be suppressed; subcutaneous hemorrhagic phenomenon occurs under a slight collision or without any cause.
