Spider veins in Houston are tiny veins under the skin that appear darker than normal and can cause itching or burning of the skin. Spider veins are often unsightly, and many people feel understandably insecure about the appearance of red or purple, web-like veins. Spider veins are different from varicose veins, which tend to indicate a more serious underlying medical problem and can cause leg pain, heaviness and cramping. However, both types of veins occur in the lower extremities as the result of pooling blood. Although the biggest risk factor for getting spider veins is your genetics (family history), there are some things you can do to prevent them. Keep reading to learn how leg elevation, frequent exercise, compression stockings and good footwear can prevent spider veins.
Quick Answer: Spider veins cannot always be prevented, because family history, hormones and age play a large role. You can, however, lower your chances of getting new ones and slow their spread. Staying active, avoiding long periods of standing or sitting still, wearing graduated compression, keeping a healthy weight, choosing low-heeled shoes, protecting your skin from sun damage and limiting heat on the legs all help. Existing spider veins do not fade on their own, but they can be treated with sclerotherapy.

Leg Elevation
Preventing spider veins is sometimes a matter of simply keeping your legs elevated when you can. If you are like most people, your job may require a great deal of sitting or standing. When you are sedentary, blood can accumulate and pool in your lower body and legs. To prevent spider veins, try to avoid standing for long periods of time. When seated, try to occasionally elevate your legs to decrease the pressure on your veins. When the blood exerts too much pressure in concentrated areas of tissue, the veins can become weak and spider-like.
Frequent Exercise
Regular exercise goes a long way towards preventing spider veins and easing symptoms of vascular disease. Even if you have an occupation that requires you to be behind a desk, try to get up for a brisk walk every hour or two. Even a short period of activity is highly effective in promoting blood flow.
Compression Stockings
Graduated compression stockings are also effective at helping to circulate the blood in your legs. These stockings are tightest at the ankle, with the pressure gradually decreasing up the legs. This helps to remove the pooled blood from the legs. Unlike the old days when these were considered “granny hose”, compression stockings are now much more fashionable, and come in sheer forms, leggings, and lots of different colors.
Good Footwear
Women who wear high heels regularly can have higher rates of both spider veins and venous insufficiency. When your calf muscles contract, they help to pump the blood out of the legs and back toward the heart. High heels disable the calf muscles from fully lengthening and contracting during walking, causing more blood to pool in the legs. Conversely, flat or low-heeled shoes promote significantly healthier blood flow.
Can Spider Veins Be Prevented? What Is and Is Not in Your Control
Spider veins, which doctors call telangiectasias, are tiny dilated vessels just under the skin, usually less than about a millimeter wide. They appear as red, blue or purple lines, often in fan- or web-shaped clusters on the thighs, behind the knees, around the ankles and sometimes on the face.
They form when the walls of these very small veins weaken and stretch under pressure. In many people, that pressure comes from slightly larger, blue-green reticular veins that sit a little deeper and feed blood into the spider web on the surface. In others, it reflects a broader problem with the valves in the leg veins, which is why spider veins sometimes appear alongside varicose veins.
Honesty matters here. If your mother and grandmother had spider veins, there is a good chance you will too, whatever you do. Prevention is really about lowering the pressure on your veins and protecting their walls so you develop fewer new veins, more slowly.
| Risk factor | Can you change it? | What helps |
|---|---|---|
| Family history | No | Start preventive habits early and watch for changes |
| Female hormones, pregnancy, menopause | Partly | Compression during pregnancy; discuss hormone options with your doctor |
| Age | No | Regular activity to keep the calf pump strong |
| Prolonged standing or sitting | Yes | Movement breaks, calf exercises, compression at work |
| Excess weight | Yes | Gradual weight loss lowers pressure in the leg veins |
| Sun exposure (face and legs) | Yes | Sunscreen and protective clothing |
| Heat on the legs | Yes | Limit hot tubs, saunas and long hot baths |
| High heels and tight clothing | Yes | Low, supportive shoes and less restrictive waistbands |
How Spider Veins Develop: The Pressure Behind the Web
Leg veins are built to move blood uphill, back toward the heart. One-way valves inside them stop blood from falling back down, and the calf muscles squeeze the veins with every step. When you stand still, sit for hours or carry extra weight, pressure in the lower leg veins rises. Over time, the smallest and most fragile vessels near the surface give way first.
Hormones add to this. Estrogen and progesterone relax the walls of veins, which is one reason spider veins are much more common in women and often appear or multiply during pregnancy. The extra blood volume of pregnancy and the pressure of the growing uterus on the pelvic veins push the pressure higher still. Many women notice new spider veins with each pregnancy.
Spider veins on the face
Facial spider veins have somewhat different triggers, including sun damage, rosacea, heat, alcohol and harsh skin treatments. Sun protection and gentle skin care are the main preventive steps for these.
Prevention Habits Beyond the Basics
The original article above covers four pillars: elevation, exercise, compression and footwear. Here are additional habits that support those efforts and that we often discuss with patients.
- Protect your skin from the sun. Ultraviolet light breaks down collagen in the skin, which supports the walls of the tiny surface vessels. Sunscreen on exposed legs and face helps, particularly in the strong Houston sun.
- Keep heat off your legs. Hot tubs, saunas, heated car seats and long hot baths dilate surface veins. Occasional use is fine, but daily heat can make spider veins more prominent.
- Manage your weight. Every extra pound adds pressure to the leg veins. Gradual weight loss reduces that load and makes the other habits more effective.
- Avoid very tight clothing at the waist and groin. Restrictive shapewear and waistbands can slow blood flow out of the legs.
- Eat enough fiber and drink water. Constipation and straining raise pressure in the abdomen and, in turn, in the leg veins.
- Move during long trips. On flights and drives, flex your ankles regularly and get up whenever you safely can.
- Be thoughtful with hormones. If you are considering estrogen-containing birth control or hormone therapy and have a strong family history of vein problems, mention it to your doctor.
Does crossing your legs cause spider veins?
This is one of the questions we hear most often. Crossing your legs is not thought to be a direct cause of spider veins. The bigger issue is sitting still for long periods, whatever position your legs are in. Getting up and moving regularly matters far more than how you sit.
Prevention During Pregnancy
Pregnancy is one of the most common times for spider veins to appear, and some will fade partly in the months after delivery. Prevention steps that are generally safe during pregnancy include:
- Wearing maternity compression stockings, ideally from early in pregnancy, if your obstetrician agrees
- Lying on your left side when resting, which takes some pressure off the large vein on the right side of the abdomen
- Walking daily and raising your legs when you can
- Avoiding long periods of standing still
Treatment of spider veins is usually postponed until after pregnancy and breastfeeding. Waiting also lets you see which veins fade on their own.
When Spider Veins Are a Sign of Something More
Most spider veins are a cosmetic concern. Some, however, are a clue to a deeper vein problem. A dense fan of small veins around the inner ankle or foot, sometimes called an ankle flare, can be an early sign of chronic venous insufficiency. Consider a vein evaluation if your spider veins come with:
- Aching, heaviness or tiredness in the legs, especially later in the day
- Ankle swelling that leaves a sock mark
- Itching, burning or restless legs at night
- Brown discoloration or dry, scaly skin near the ankles
- Bulging varicose veins nearby
- Spider veins that come back quickly after treatment
Treating spider veins on the surface while ignoring reflux in a deeper vein often leads to disappointing results, because the pressure that created them is still there. That is why we check before we treat.
How Existing Spider Veins Are Treated
Prevention slows new veins; it does not erase existing ones. For those, the most widely used treatment is sclerotherapy. A very fine needle is used to inject a solution into the vein, which irritates the lining so the vein collapses and is gradually absorbed. Each session typically takes 15 to 45 minutes, and most people go straight back to normal activities. Several sessions are often needed, spaced a few weeks apart.
Treating the feeding reticular veins at the same time usually gives cleaner, longer-lasting results. If an ultrasound shows a refluxing larger vein, that is treated first. You can learn more on our spider vein treatment page.
Keeping results after treatment
Once spider veins are treated, those particular veins do not usually return. New ones can develop over time, though, because the tendency remains. The habits described above, plus wearing compression for a short period after each sclerotherapy session as directed, help protect your results and slow the appearance of new veins.
Seek prompt medical care if you notice:
- Bleeding from a vein near the ankle or foot that does not stop with firm pressure and leg elevation
- Sudden swelling, pain or warmth in one leg, which may be a deep vein thrombosis
- A hard, red, painful cord along a vein, especially with fever
- Sudden shortness of breath or chest pain, which needs a call to 911
How We Evaluate Spider Veins
- Focused history. We ask when your veins appeared, whether they cause symptoms, your family history, pregnancies, hormone use and any previous treatments.
- Examination. We look at the pattern of spider and reticular veins while you stand, check for swelling, skin changes and varicose veins, and note where the feeder veins run.
- Ultrasound when needed. If symptoms, an ankle flare or larger veins suggest deeper reflux, a venous duplex ultrasound in our IAC-accredited vascular lab checks the main leg veins first.
- A clear plan. We explain whether you need cosmetic treatment only or treatment of an underlying vein first, how many sessions to expect and how to protect your results.

Frequently Asked Questions
Are spider veins genetic?
Family history is one of the strongest risk factors for spider veins. If close relatives have them, you are more likely to develop them, although lifestyle habits can influence how many appear and how quickly.
Can exercise get rid of spider veins?
Exercise improves circulation and may help slow the appearance of new spider veins, but it does not make existing ones disappear. Established spider veins are usually treated with sclerotherapy.
Do compression stockings prevent spider veins?
Graduated compression stockings reduce pressure in the leg veins and may help limit new spider veins, especially for people who stand or sit for long periods or are pregnant. They do not remove veins that are already there.
Do spider veins go away after pregnancy?
Some spider veins that appear during pregnancy fade partly within a few months after delivery. Those that remain can be treated once pregnancy and breastfeeding are complete.
Are spider veins dangerous?
Spider veins on their own are usually harmless and mainly a cosmetic concern. When they come with leg aching, swelling or skin changes, they can be a sign of underlying venous insufficiency that is worth checking with an ultrasound.
Will spider veins come back after sclerotherapy?
Treated spider veins usually do not return, but new ones can develop over time because the underlying tendency remains. Healthy habits and treatment of any deeper vein reflux help keep results longer.
