Long-Term Fluid Buildup
Ulcers are caused by long-term fluid buildup in the affected tissues, the result of increased blood pressure within the affected veins.
- The extra fluid that builds up in your body makes it hard for the blood to feed cells and get rid of waste products.
- Deprived of sufficient oxygen, the tissue becomes poorly nourished and fragile.
- The disorder is common on the ankles because there is less supportive tissue in this area.
Venous ulcers may also be caused by a variety of medical conditions including:
- Weakened or damaged veins
- Previous deep vein thrombosis Postphlebitic syndrome
