In some cases, leg vein health can be negatively affected by things that are out of your control: age, genetics and major body changes such as pregnancy. However, some daily habits can also lead to venous issues, and changing these habits can reduce your risk of developing unhealthy veins. The vascular surgeons in Orlando at Central Florida Vein & Vascular Center are here to outline a few common habits worth examining more closely.

What Is Venous Insufficiency?

The human circulatory system transports blood to and from the heart. Arteries carry blood out to the body’s organs and limbs, and veins transport it back. On the return trip, some of the blood must flow upward through leg veins, so leg muscles contract as you walk, which puts pressure on the veins and assists in moving the blood upward. And that the blood continues its upward journey, and not go back down, the veins contain one-way valves. Venous insufficiency is a condition that occurs when the walls and/or the valves in a person’s leg veins are not working properly, creating a situation in which it is difficult for the blood to return from the legs to the heart. When this is a long-term rather than temporary problem, it is called chronic venous insufficiency, or CVI. As a result, CVI causes blood to “pool” or collect in these compromised veins; this pooling is also called stasis.

Venous insufficiency can cause both varicose veins and superficial veins. Varicose veins are swollen and raised and typically occur on the legs. Superficial (or spider) veins are less serious visible (but not raised) veins that sometimes occur on the leg or face.

Venous Insufficiency Factors

Causes of varicose veins

A number of factors may increase your risk for varicose veins. These include:

  • Family History: If you have family members who have had varicose veins, then it’s more likely that you will, too. But even if both of your parents have or had varicose veins, it doesn’t automatically mean that you also will develop the condition. The genetic predisposition is for a flaw that allows the veins to stretch and create faulty valves, and this trait is what causes the varicose and superficial veins. This genetic trait occurs in up to 60 percent of Caucasians, as well as in Hispanics and Asians (but not as much in African Americans).
  • Age: Increased age is another factor that can increase the risk of developing varicose and superficial veins. As our veins and their valves age, they start to not work as well, just like many other body parts. When the veins become less reliable, the valves begin to allow blood to flow backward.
  • Gender: For a combination of reasons, women are more likely to develop varicose veins. One often-cited factor is the change in hormonal levels that occurs at various times in a woman’s life, such as during pregnancy, premenstruation, and menopause. This is because certain hormones cause the vein walls to not be as rigid and the levels of these hormones are increased. It is also important to note that if you participate in hormone replacement therapy or are taking birth control pills, this also may increase your risk of developing varicose veins. As a side note, remember that gender is not a deciding factor in whether you develop varicose or superficial veins. Men are not in the clear here and should regularly check for the condition.
  • Pregnancy: Relating to the previous point, another factor that contributes to women developing varicose veins is carrying a child. During pregnancy, the baby increases the pressure on the legs and hormones contribute to varicose veins as well. The good news is that varicose veins caused by pregnancy tend to self-resolve within a year after giving birth.
  • Being Overweight: Obesity increases the pressure on veins. We all know that carrying extra weight is unhealthy for a lot of reasons and this is one more. Interestingly, though, being in shape doesn’t mean you won’t develop varicose or superficial veins. While exercise, in general, is a tremendous way to keep your veins healthy and in top condition, certain exercises can increase your varicose vein risk. Weightlifting and activities that put great strain on the muscles and veins increase your risk, as do cycling and other sports with highly repetitive leg motions. While we’re not saying to avoid sports and be a couch potato (see our next point), it is important for people of all activity levels to be aware of their specific risk level for varicose veins.
  • Lack of Movement: Simply put, blood doesn’t flow well if you’re in the same position for a long time. A sedentary lifestyle makes your veins work overtime to get blood back to the heart. With an active person, the movement of the legs helps return the blood and takes some of the burden off the veins.

Why Some Habits Are Bad For Veins

Your veins work hard to circulate blood throughout your body. The veins in your legs, on the other hand, have an additional challenge. Your leg veins have to pump blood upward and against the flow of gravity. Normally, valves in the vein are strong enough to do this, but they can become damaged or weakened over time. Blood can then pool in the vein, and from there, a varicose vein is formed.

Some daily habits that we may not think about can harm these vein valves. In order to keep them healthy, we want to pinpoint habits that can damage the veins and replace them with habits that make them stronger.

Habits That Lead To Varicose Veins

Prolonged Standing

Your job may require you to stand for long periods of time. The effects of gravity combined with hours of standing puts tremendous pressure on the veins—which, as we know, is something you’ll want to avoid, as it can harm the veins. Now, we’re not suggesting that you start interviewing for a job where you’re not on your feet for eight hours a day, but it’s simple to find small ways to change up your work routine. Can you take a short walk? Can you get a break to sit? Just a little bit of extra movement during the day will help take pressure off your veins. Compression hose can also be used to help counterbalance the pressure build-up from the gravity effect.

Crossing Your Legs

You may have heard to not cross your legs, as it causes varicose veins. This isn’t entirely true. Crossing your legs doesn’t put so much pressure on your veins that you’ll develop varicose veins—but you may put yourself at risk of spider veins. When you cross your legs, the major veins behind the knee get compressed and prevent venous drainage of the leg veins. Similarly, crossing legs puts pressure on the veins in the groin, also preventing venous return and increasing venous congestion. Crossing your legs for a few minutes here and there won’t hurt. But, similar to standing, try not to do it for hours a day. Keep two feet flat on the floor instead—or, if you’re often sitting at a desk for work, you can try having your feet elevated on a small stool for some additional comfort.

Allowing Leg Muscles to Weaken

Exercise is good for just about everything—including varicose veins. When you stay stagnant for long periods of time, you can lose muscle mass. This causes veins to dilate and varicose veins to form. This happens most commonly in injured athletes, who have large amounts of muscle that they’re suddenly unable to maintain. While maintaining muscle is important, building muscle is critical as well. This doesn’t mean you have to start running marathons. You don’t have to set aside long periods of time for the gym, either. Just take a short walk every day. Short walks are ideal for those who spend much of their day sitting or standing and will help to keep the calf muscles strong. One of the strongest pumps driving venous return is the calf muscle pump. The veins are inside the calf musculature, so when strong calf muscles contract, there is forceful propulsion of venous blood back to the heart.

Eating Too Much Salt

Eating a low-sodium diet isn’t just a trend—eating too much salt certainly has some bad effects on your health, including an increased risk of developing varicose veins. A high-sodium diet can cause your body to retain water, which puts more pressure on your veins. This pressure, as we’ve established, harms the vein valves and can create varicose veins.A little bit of salt isn’t bad for you. We all like our food to have a little flavor. It’s important, although, to take a quick look at the food labels before you pick something up from the grocery store. Some foods can have a surprising amount of sodium—and there’s often a low-sodium option available.

Genetic Factors

Some risk factors for varicose veins are out of our control. Genetics often plays a role in whether someone will develop venous issues, and the hormonal changes in pregnancy can also put women at a higher risk. Does this mean that you shouldn’t change your daily habits? Of course not! Doing all you can to strengthen your veins will still lower your risk of developing varicose veins.

Wearing Heels

Just like crossing your legs, you may have also heard that high heels are terrible for your venous health. Pulling out a nice pair of heels for a special event isn’t going to harm you, but wearing them daily could cause damage.

When you wear high heels, you don’t contract your leg muscles as much as you would if you were wearing flats. This contracting of muscles is important—it gives your veins a helpful push in circulating blood. When you’re routinely wearing high heels, you’re also routinely causing less movement of blood. Over time, that can lead to damaged vein valves.

So, should you throw out all your pairs of heels and go shopping for flats? Not necessarily. As we’ve said before, occasional wear is okay—but if you’re wearing them every day, consider limiting your usage.
