The causes of varicose veins are related to our overall health and certain hormonal changes. Varicose veins are veins that are swollen or abnormally full of blood. This happens most often when the valves in the veins that control blood flow and drainage malfunction. There are essentially three types of veins that have to function properly to prevent varicose veins from forming. They are the superficial, deep veins and perforator veins. The deep veins are connected to the superficial or surface veins via the perforator veins. When any of these veins stop working to control blood flow and drainage, a varicose vein occurs, appearing as a purple or blue vein on the surface of the skin. They can also appear as twisted or bulging veins when they become more pronounced.
Main varicose vein causes
When the skeletal muscles contract, they help the vein valves to open and close to move blood down into the legs. As the muscles contract, the vein valves open and blood moves up toward the heart; when the muscles release, the vein valves close and blood is prevented from flowing. Sometimes, often due to a sedentary lifestyle, hormonal changes which cause the valves to be lax, or other problems, the valves don’t open and close and some blood remains trapped in the veins, instead of moving through them correctly. When looking at the causes of varicose veins, this is the reason.
Probable causes of varicose veins are obesity, as this causes blood to be restricted in its flow through the veins, as well as vein malfunction due to inaccurate pressure in the vein walls and valves. Obesity also causes the veins to become deformed and sometimes even pinched or weakened. Another cause is hormonal fluctuations such as puberty or menopause. These changes cause a temporary fluctuation of blood flow and can sometimes lead to varicose veins. When varicose veins occur in the face, primarily the nose, they are called Telangiectasias, which are a small cluster of blood vessels that become spider-like on the surface of the skin. Pregnant women sometimes develop this condition due to the great increase in blood volume in the body.
Sometimes varicose veins happen due to familial history. If the veins are naturally weaker due to your DNA, you may not be able to prevent them with just exercise and a good diet. Still, other causes of varicose veins are, having to stand or sit in one place for too long or crossing a leg for a long time; this can impede the blood flow into the legs.
