The Genetic Link: Is Vein Disease Hereditary?

Vein disease is a generic term that covers all conditions that affect the venous system. Mild symptoms and conditions are often minor events with very little concern. However, the conditions can progressively worsen if a family history or external factors are involved. 

There is still a lot to be learned about the link between genetics and vein disease. Still, most professionals do agree that there is some type of connection. This article will explore the link, symptoms and how you can prevent the condition.

Understanding Vein Disease

Vein disease is a range of conditions that affect the venous system. The venous system is responsible for returning deoxygenated blood back to the heart. The most common form of vein disease is chronic venous insufficiency (CVI), where the body struggles to pump the blood back to the heart and ends up pooling in the legs.

There are three common venous disorders:

  1. Varicose veins: Most will only get varicose veins very mildly, and for them, it is usually just a cosmetic concern. But for some, this condition escalates, causing further complications. The cause is a slow tweaking of the vein walls and malfunction of the vein valves. The blood collects in the veins instead of continuing to the heart. The veins can become enlarged, dilated and overfilled with blood. They can appear swollen and raised with a blush purple or red color. In severe cases, it can be painful and cause a burning or throbbing sensation in the legs.

  1. Spider veins: Similar to varicose but on a smaller level. The name comes from the appearance of the veins, which are close to the surface and appear in a small web of blue and red lines. The biggest difference between spider veins and varicose is that the former are painless and rarely cause any health problems. 

  1. Deep Vein Thrombosis (DVT): This serious condition involves the blood forming a clot deep in the vein, usually in the leg. It is unclear how DVT is hereditary — but like the other conditions, your chances of getting it increase if it runs in the family. The concern with DVT is that if the clot breaks loose, it could cause a life-threatening situation if it makes it up to the lungs or heart. Ultrasound imaging is used to create pictures of the swollen area to confirm diagnoses.

Definition and Symptoms of Vein Disease

Vein disease involves issues with the blood flow back up to the heart. Unlike the arteries, veins have thin walls and a series of one-way valves to prevent backflow. The valves open as the blood flows towards the heart and then close to stop it from flowing backward. Muscle contractions in the lower legs act as pumps, which help counteract the natural pull of gravity.

Common symptoms of vein disease involve:

  • Pain or aching
  • Swelling
  • Heavy or tire legs
  • Spider and varicose veins
  • Skin changes
  • Ulcers, particularly around ankles
  • Blood clots

Is Vein Disease Hereditary?

While no study has been conducted to prove the hereditary factor for vein disease, strong evidence suggests a link. Studies have been done on twins, suggesting that there are various types of heredity and environmental factors. Research has also shown that a single genetic anomaly and several mutations could be responsible. 

So, are varicose veins hereditary? While researchers are still finding out the link between vein disease and the genetic component, you may be at an increased risk if one of your parents has varicose veins.

There are some speculations as to whether men or women get varicose veins more frequently, as survey numbers are always very close. But what it shows is that women tend to get it earlier, with first symptoms appearing at 30, while men only start at 36. Age also seems to be an increasing factor. 

The venous system in humans is affected by blood pressure, unlike any other mammals, purely because we are the only ones that stand. Chronic venous disease (CVD) affects much of the adult population. While research in recent years has improved our understanding of the disease, there are more questions than answers. 

The biggest reason is that vein disease can be affected by so many factors, such as:

  • Age
  • Gender
  • Pregnancy
  • Lifestyle
  • Hormonal changes

The list goes on as it would appear a lot of factors are involved. It is not just genetics that could cause vein disease. Many health care professionals believe there is a strong connection and that if vein disease is evident in family medical histories, it is best to proceed with caution through:

  • Early screenings: If you have a family history of vein disease, get screenings as a safety precaution. 
  • Lifestyle modifications: If you have a higher risk, consider making changes to your lifestyle, such as implementing regular exercise and avoiding sitting for prolonged periods. 
  • Monitoring changes: Keep an eye on and note any changes in spider or varicose veins. If they appear, chat with your health care professional about them to learn how to prevent progression.

Regular Checkups and Early Detection

Regular checkups allow a professional to keep track of the progression. Spider veins are not severe, but if the conditions progress steadily, early detection and intervention are a lot easier in the early stages than later when the veins get large and entangled. Health care professionals can create personalized treatments to address the stages, knowing how long it took for you to get to that stage of vein disease.

The health care professional will usually review your medical history along with your family’s and all the symptoms you experience. They will do a visual and physical examination and potentially examine your legs. If there is any concern or if they consider it necessary, the health care professional will recommend a diagnostic test. An example of this will be some imaging tests, such as a Doppler ultrasound, to assess the blood flow and vein structure. 

Early detection may result in less invasive treatment options than ones where the vein condition has progressed to a late stage. It can also prevent complications, such as ulcers or bleeding. As the health care industry says, prevention is better than cure.
