What is Varicose Vains?
Varicose veins are caused by an enlarged blood vessel and a lack of oxygen. Varicose vains occur when your blood vessels become so narrow they can't allow blood to flow freely and the veins start to bleed. This is not a problem if the varicose veins are only very small. If your veins are large, they can rupture and cause a blood clot. This is very serious, but there are several different kinds of varicose veins.
Varicose veins are large blood vessels that have become too narrow. Usually these are caused by a blood clot or a blocked artery. A blood clot usually forms when the blood goes into the vein. The clot may then grow and clog the vein. A blocked artery is usually the cause of this condition.
This condition usually goes away with time or it can be treated with surgery. The condition can be serious if the vein continues to clog or you have to undergo an angioplasty. A varicose vein is most common in the arm or leg, especially in the legs. In this condition, your veins become constricted, and the blood can't flow through. A vein usually grows back normally after a few days, usually with no further complications.
