Negosentro | Causes of Varicose Veins | Varicose veins are enlarged, twisted veins that look like swollen cords under the surface of your skin. Each vein has an artery and a tube called a “lumen.” In varicose veins, the walls get weak and let blood leak into nearby tissues. Then, they swell up and get bigger.
Varicose veins usually happen in your legs, but they sometimes occur in other parts of your body. They typically don’t hurt. But if you have many of them or the walls get thinner and break open, blood from the vein can spill into nearby tissues. This is called a “hemorrhage.” It makes a bruise and can hurt a lot. Many people seek treatment from a specialist in varicose veins in Upper East Side for cosmetic reasons.
In this article, we look at some of the different causes of varicose veins.
Failure of Valves in the Veins
Veins are blood vessels that take the blood back towards the heart. A series of one-way valves allow the blood to be pumped forward but prevent it from flowing backward. These valves can become damaged or incompetent, meaning they no longer function properly, and thus the wrong direction of flow is allowed resulting in varicose veins.
Being overweight can cause varicose veins because it increases the pressure on the veins. If you are overweight, losing weight may make your varicose veins go away or at least become less severe. A sudden weight gain may also cause varicosities. For example, after a large meal and digestion of food and fluid (which takes about six hours), the blood will be diverted to the intestinal tract and away from the veins in your legs. This can cause varicose veins because not enough blood is pumped back to the heart due to the diverted blood flow.
The a vascular malformation is an abnormal connection between arteries and veins. This malformation causes the blood to go directly from the artery into the vein without going through the capillary bed (the part of your circulatory system where gas, nutrients, and waste products are exchanged). The direct connection prevents oxygenated blood from being pumped into the arteries, which means less oxygen reaches your tissues. The affected area will often swell and become painful due to the pooling of venous blood. This condition may also result in chronic ulceration because of a lack of circulation to the affected area.
A sedentary lifestyle can contribute to varicosity because the veins are not used as much. This is especially true for older people who have been sitting in one place for long periods, such as during a long car ride or at work. When you stand up after sitting or lying down for a long time, gravity pulls your blood toward your feet. The veins in your legs are not used to holding so much blood, so it is more difficult for them to pump the extra volume of blood back up toward your heart.
In summary, varicose veins are a common condition where you develop enlarged, twisted veins that look like swollen cords under the surface of your skin. Common causes of varicose veins include a sedentary lifestyle, vascular malformation, overweight, and failure of the valves in your veins.
