Chronic Venous Insufficiency Causes

Chronic venous insufficiency is a deep vein disease in which the great or small saphenous veins get diseased and the valves in the veins collapse, which leads to restricted blood circulation, which, in turn, leads to the accumulation of blood in the damaged veins. Over time, if venous insufficiency isn’t treated, you may experience various other complications like the formation of spider and varicose veins, skin infections, bleeding, skin discoloration, and even deep vein thrombosis. The latter of these is especially dangerous because it’s the formation of blood clots in the deep veins, which can then travel to the lungs and lead to pulmonary embolism. But, you must be wondering, why do veins collapse? What is chronic venous disease and what are the causes for varicose veins? In this article, we’ll discuss the details of chronic venous insufficiency.

What is Chronic Venous Disease?

We have two types of blood vessels in our body — arteries, which carry blood from the heart to different parts of the body; and veins, which carry blood from the extremities to the heart. There are valves in the veins that serve as one-way doors to facilitate the flow of blood from the limbs to the heart. This is especially useful when it comes to the legs because the blood in the leg veins has to travel up to the heart, against the force of gravity. As such, the valves in the veins prevent blood reflux and facilitate smooth blood flow to the heart. However, sometimes, these valves malfunction and collapse, which causes blood to flow back down due to gravity and pool around the leg veins. This entire condition is known as chronic venous disease and it’s one of the worst circulatory problems out there.

What are the Causes for Varicose Veins? Why Do Veins Collapse?

So chronic venous insufficiency occurs when the valves in the veins malfunction and the veins collapse. But why do veins collapse and what are the causes for varicose veins? In this section, we’ll explore some of the primary risk factors for varicose veins.

Genetics

Genetics is the primary risk factor for venous insufficiency. People whose parents have vein disease are at least 90% likely to also have venous insufficiency. This is true for a number of factors. You may have genetic traits with different levels of collagen, weaker vein valves, different blood vessel development, or a number of other factors.

Biological Sex

One’s biological sex — male or female — is a huge determinant of vein disease. In fact, venous insufficiency affects at least 50% of all women to various degrees while it only affects 30% of all men. This is again due to various physiological factors within the female body. Female hormones like estrogen and progesterone, for example, affect vein wall relaxation. Differences in fat deposition can also affect how likely you are to suffer from venous insufficiency.

Age

As we grow older, the valves in the veins also grow weaker and are more likely to malfunction, incapable of supporting the weight of your body. This increases the risk of venous reflux, which leads to the formation of spider and varicose veins.

Obesity

The heavier you are, the greater the pressure you apply on the veins, which can cause vein valves to malfunction. Furthermore, obesity also increases the estrogen levels in your body, which also causes vein walls to weaken. Over time, this can lead to venous insufficiency and the formation of varicose veins. However, it’s important to note that being slightly overweight doesn’t increase your risk of vein disease — being clinically obese does.

Pregnancy

You are almost certain to get spider veins during pregnancy. Furthermore, you may also experience several signs of chronic venous insufficiency. There are a number of factors that make chronic venous insufficiency likely during pregnancy:

  • Female hormones like estrogen and progesterone increase dramatically during pregnancy, leading to vein wall relaxation.
  • The amount of blood in your body also increases, which causes veins to dilate and expand, thus leading to venous insufficiency and varicose veins.
  • The uterus may apply pressure on the veins carrying blood from the legs to the heart, which can lead to dilation of veins.

Complications of Chronic Venous Insufficiency

Seeking vein collapse treatment is crucial if you’re suffering from chronic venous insufficiency. This is true for a number of reasons.

  • Spider and Varicose Veins: Chronic venous insufficiency leads to the formation of spider veins and varicose veins. Spider veins are unappealing spider web-like clusters of blood vessels on the surface of the skin. Varicose veins are large twisted veins that protrude from the surface of the skin.
  • Intense Bleeding: Varicose veins are essentially bulging and dilated blood vessels. As such, they may start bleeding profusely if you bump or scratch them.
  • Skin Diseases: You suffer from a number of skin diseases, discoloration of the skin, eczema, etc. Your skin also becomes hard and scaly.
  • Leg Ulcers: These are non-healing wounds on the surface of the skin due to the lack of blood circulation.
  • Deep Vein Thrombosis: This is a condition in which the accumulated blood in the veins clots and hardens. Over time, if these clots break away, they may travel to the lungs and lead to a potentially fatal condition called pulmonary embolism.

Summary:-

Chronic venous insufficiency is a deep vein disease in which the great or small saphenous veins get diseased and the valves in the veins collapse, which leads to restricted blood circulation, which, in turn, leads to the accumulation of blood in the damaged veins. Over time, if venous insufficiency isn’t treated, you may experience various other complications like the formation of spider and varicose veins, skin infections, bleeding, skin discoloration, and even deep vein thrombosis. The latter of these is especially dangerous because it’s the formation of blood clots in the deep veins, which can then travel to the lungs and lead to pulmonary embolism. But, you must be wondering, why do veins collapse at all? Well, your veins may collapse and your vein valves may malfunction due to various factors. Genetics is the primary risk factor for venous insufficiency. One’s biological sex — male or female — is a huge determinant of vein disease as women have a 50% chance of venous insufficiency while men only have a 30% risk. You are also more likely to suffer from venous insufficiency as you grow older. Furthermore, pregnancy makes venous insufficiency almost inevitable for a number of reasons.
