Venous System and Venous Disorders

If you feel pain or discomfort in your leg veins, you may have a venous disorder. Luckily, specialized vein doctors are available to help you. These professionals diagnose and treat any ailments you may have that involve your veins. In order to understand your vein problems better, you must first understand your venous system and how it works.

How venous system works?

Your venous system works through a complicated system of large and small veins that return blood from different parts of your body to your heart. Normal veins have a series of valves that open and close to direct blood flow from the surface of the legs to the deep leg veins. With the help of the calf muscles pumping blood back to the heart, the valves also control the pressure in smaller veins on the legs’ surface. These veins usually have one-way valves that prevent backflow of blood due to gravity and facilitate the flow of blood back to the heart. Whenever these the valves experience failure in the veins, blood can flow backward and pool in the legs. Some of these problems may be considered mild, however, it is possible you will experience a feeling of heaviness in the legs, aching, unsightly veins i.e. Varicose Veins etc.

Your body has three types of veins: deep, superficial, and short veins.

  • Deep veins are necessary to facilitate blood flow towards the heart because of the muscles surrounding them; the muscles squeeze, which forces the blood upwards. Your calf muscles are among the most important muscles in your body, as they carry more than 90% of the blood from your legs towards your heart.
  • Superficial veins can be found under the fatty layer of your skin and function in the same way as deep veins, but do not have muscles surrounding them. Because of this, blood flows back to the heart slower than it does in deep veins.
  • The short veins are involved in linking the deep and superficial veins and are also called connecting veins.

As with other parts and organs of the body, there are problems that can occur with your veins. Some of the common issues with venous systems include arteriovenous fistulas (or arteriovenous malformations), thrombophlebitis, and thrombosis (varicose veins).

Why and how you have these venous system issues?

Arteriovenous fistulas are abnormal connections between the arteries and veins, and can be seen either at birth or later in life. Thrombophlebitis is caused by blood clots and inflames superficial veins. Thrombosis is when blood clots occur in a deep vein, which results in varicose veins occurring due to defects in the veins. Many of these conditions can also occur due to lack of exercise, sitting or standing for long periods of time, smoking, obesity, hormonal birth control, or pregnancy.

Although it may seem devastating to have venous system issues, the good news is that they are preventable. By keeping your weight down, eating healthy, and exercising, you can prevent issues like varicose veins, even if it’s in your genes. Even after you’ve developed these venous system issues, all hope isn’t lost — there are a number of effective ways to treat them.

Solving venous system issues starts with improving circulation. A simple and non-invasive treatment involves wearing prescription compression stockings. These add pressure to your legs and help improve blood flow back to your heart from your legs. Other treatments include medication and surgery for cases that are more serious.

As you get older, you may notice more pronounced veins, some of which aren’t very attractive and may give you cause for concern. Although they are typically harmless, pronounced veins may be signs of mild venous disease. There are many risk factors for venous disease, including age, gender, and the condition of your health. Read on to find out more about venous disease causes.

  • Varicose Veins

Varicose veins are veins that look thick and rope-like. They may protrude out of your legs. These veins are stretched out because blood has pooled for a period of time. Varicose veins are the result of one-way valves for your veins failing to work properly, which can be the result of standing or sitting for too long. Other causes of varicose veins include obesity, smoking, hormonal birth control, and lack of exercise. Another main cause is pregnancy, as the fetus can block the normal flow of blood in certain areas of your veins. Exercise is the best measure to prevent varicose veins. However, if you already have varicose veins, you can reduce the appearance of them and ease your pain through professional treatment.

  • Spider Veins

Although commonly lumped together with varicose veins, spider veins are actually a different ailment. They are much smaller and thinner than varicose veins, comprised of blue blood vessels that you can see under your skin. Although they are usually harmless, they can be a symptom of poor circulation and a sign of the onset of varicose veins. What causes spider veins is the same as for varicose veins: standing or sitting too long, obesity, smoking, hormonal birth control, lack of exercise, and pregnancy. Crossing your legs and wearing high heels, on the other hand, do not cause spider veins and varicose veins.

  • Vascular Malformations

Venous leg ulcers are a condition that occurs in the older population, especially women. They can be caused by poor circulation or other conditions, such as anemia, kidney problems, rheumatoid arthritis, or diabetes. Venous leg ulcers occur when there is an increased pressure of blood in the veins of the lower legs. Fluid then oozes out of the veins, which makes the legs swell, thicken, and cause damage to the skin. When the skin eventually breaks down, this becomes an ulcer.
