Causes

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.

Medical Conditions

Venous ulcers may also be caused by a variety of medical conditions including:

• Heredity
  
• Weakened or damaged veins
  
• Previous deep vein thrombosis Postphlebitic syndrome
