8. Venous Insufficiency
Arteries are responsible for transporting clean oxygenated blood from the heart to all parts of the body. Then the veins carry deoxygenated blood back to the heart. Venous insufficiency occurs when the vein valves stop the blood from flowing back. When veins fail to send the blood backward, the blood accumulates in the leg veins including in ankles. This causes the inflammation of ankle tissues.
There are various causes linked to this condition. The common being blood clots and varicose veins. In cases where blood clots are the main cause, the clots block the flow of blood; resulting in venous insufficiency. While in varicose veins, there would be severe valve damage which allows the blood to leak and build up in ankle tissue. Women are most likely to have venous insufficiency than men. The most affected age ranges from 40 to 49 in women and 70 to 79 in men.
