If you’ve started to notice twisted, bulging veins on your legs—or already have them—you’re not alone. Varicose veins are incredibly common, especially as we age. But if you’ve seen them in your parents or grandparents, you might be wondering if varicose veins are genetic.
The short answer? Yes, genetics can play a significant role—but it’s not the only factor.
Let’s break down what causes varicose veins and how much your family history really matters.
What Are Varicose Veins?
Varicose veins happen when the valves inside your veins—especially those in your legs—don’t function properly. These valves are supposed to keep blood flowing in one direction: back up toward your heart. But when they weaken or become damaged, blood pools in the veins, causing them to stretch and bulge.
These veins often appear blue or purple and can be lumpy, twisted, or rope-like. While they’re mostly a cosmetic concern for some, others experience aching, swelling, heaviness, or itching.
How Genetics Comes Into Play
Studies show that your risk of developing varicose veins increases if a close family member has them. In fact:
- If one parent has varicose veins, your chances go up by about 40%
- If both parents have them, your risk can rise to 90%
Researchers believe that inherited traits, like vein wall weakness or faulty valves, can make someone more susceptible to developing venous issues.
So if your mom, dad, or even grandparents have varicose veins, it doesn’t guarantee you’ll get them, but it does put you at a higher risk.
Other Risk Factors Besides Genetics
While genetics is a major piece of the puzzle, it’s not the only factor. Several lifestyle and health factors can increase your risk:
- The older you get, the more wear and tear on your veins.
- Women are more likely to develop varicose veins due to hormonal shifts, pregnancy, or birth control use.
- Increased blood volume and pressure on pelvic veins during pregnancy can trigger varicose veins.
- If your job keeps you on your feet or at a desk for hours, your circulation may suffer.
- Extra body weight puts more pressure on your veins.
- Movement helps blood flow, so inactivity can contribute to vein problems.
Can You Prevent Varicose Veins?
If varicose veins run in your family, you can’t completely eliminate your risk, but you can take steps to manage it. Here’s what helps:
- Exercise regularly to boost circulation
- Maintain a healthy weight to reduce pressure on your veins
- Elevate your legs at the end of the day
- Avoid long periods of sitting or standing
- Wear compression stockings if recommended by your doctor
These simple lifestyle changes won’t reverse existing varicose veins, but they can help slow progression and ease discomfort.
What Are Your Treatment Options?
If varicose veins are causing you pain or affecting your confidence, you don’t have to live with them. Treatments today are more effective and less invasive than ever.
Depending on your condition, a cardiologist or vein specialist may recommend:
- Lifestyle changes and compression therapy
- Minimally invasive procedures like sclerotherapy, radiofrequency ablation, or laser treatments
- Surgical options in severe cases
Many of these procedures are done in-office and require little to no downtime.
Conclusion
While varicose veins can be hereditary, they’re not entirely out of your control. Genetics may increase your risk, but lifestyle habits, age, and health also play a role. The good news? With the right care and treatment, varicose veins can be managed.
