Varicose veins are gnarled, enlarged veins. The
word varicose comes from the Latin root varix, which means "twisted." Any
vein may become varicose, but the veins most commonly affected are
those in your legs and feet. That's because you stand and walk upright,
which increases the pressure in the veins in your lower body.
For many people, varicose veins and spider veins — a common, mild
and medically insignificant variation of varicose veins — are simply
a cosmetic concern. For other people, varicose veins can cause aching
pain and discomfort. Sometimes the condition leads to more serious problems.
Varicose veins may also signal a higher risk of other disorders of the
circulatory system.
Varicose veins are a common condition in the United States, affecting
up to 60 percent of all Americans. Women, especially older women, are
more likely than men are to have this problem. Treatment may involve
self-help measures, or procedures by your doctor to close or remove veins.
Signs and Symptoms
Signs and symptoms of varicose veins may include:
- An achy or heavy feeling in your legs, and burning, throbbing, muscle
cramping and swelling in your lower legs. Prolonged sitting or standing
tends to make your legs feel worse.
- Itching around one or more of your
veins.
- Skin ulcers near your ankle, which represent a severe form of
vascular disease and require immediate attention.
Varicose veins are dark purple or blue in
color and may appear twisted and bulging — like cords. They
commonly appear on the backs of the calves or on the inside of the
legs. But, they can form anywhere on your legs, from your groin to
your ankle.
Spider veins are similar to varicose veins, but they're smaller. Spider
veins are found closer to the skin's surface and are often red or blue.
They occur on the legs, but can also be found on the face. Spider veins
vary in size and often look like a spider's web or a tree branch.
Other types of varicose veins include:
- Venous lakes. These are pools of blood in
the veins, often found on the face and neck.
- Reticular veins. These
flat, blue veins under the skin often appear behind the knee.
- Telangiectases.
These are fine clusters of blood vessels similar to spider veins,
reddish in color and often found on the face or upper body.
Occasionally, veins deep within the legs become
enlarged. In such cases, the affected leg may swell considerably. Any
sudden leg swelling that may or may not be accompanied by pain and
redness warrants urgent medical attention, as it may indicate a blood
clot — a condition known
medically as thrombophlebitis.
Causes of varicose veins
Arteries carry blood from your heart to the rest of your tissues. Veins
return blood from the rest of your body to your heart, so the blood can
be recirculated. To return blood to your heart, the veins in your legs
must work against gravity. Muscle contractions in your lower legs act as
pumps, while toned, elastic vein walls help blood return to your heart.
Tiny one-way valves in your veins open as blood flows toward your heart
then close to stop blood from flowing backward.
Varicose veins occur when the valves in your veins malfunction. As you
get older your veins can lose elasticity, causing them to stretch. When
this happens, blood that should be moving toward your heart may flow
backward. Blood pools in your veins, and your veins enlarge and become
varicose. The veins appear blue because they contain deoxygenated blood,
which is in the process of being recirculated.
Some pregnant women develop varicose veins. Pregnancy
increases the volume of blood in your body, but decreases the flow
of blood from your legs to your pelvis. This circulatory change is
designed to support the growing fetus, but it can produce an unfortunate
side effect — enlarged
veins in your legs. Varicose veins may surface for the first time or
may worsen during late pregnancy, when your uterus exerts greater pressure
on the veins in your legs. Hemorrhoids are varicose veins located in
and around the anus.
Risk factors
These factors increase your risk of developing varicose veins:
- Age. Aging causes wear and tear on the valves in your veins that
help regulate blood flow. Eventually, that wear causes the valves to
malfunction.
- Sex. Women are more likely than men are to develop the condition.
Hormonal changes during pregnancy, premenstruation or menopause may
be a factor. Female hormones tend to relax vein walls. Taking hormone
replacement therapy or birth control pills may increase your risk of
varicose veins.
- Genetics. If other family members had varicose veins, there's a greater
chance you will too.
- Obesity. Being overweight puts added pressure
on your veins
- Standing for long periods of time. Your blood
doesn't flow as well if you're in the same position for long periods.
When to seek medical advice for varicose vein treatment
Self-help measures can help you ease the pain
of varicose veins and may prevent them from getting worse. But if you're
concerned about how your veins look and feel and self-care measures
haven't stopped your condition from getting worse, see your doctor.
Screening and diagnosis
In making a diagnosis, your doctor will examine your legs while you're
standing and will look for swelling. He or she may also ask you to describe
the pain and aching in your legs. Finally, your doctor may perform an
ultrasound test to see if there's any evidence of a blood clot. Your
primary care doctor may recommend that you see a doctor who specializes
in vein conditions (phlebologist) or a doctor who treats skin conditions
(dermatologist or dermatology surgeon).
Varicose Veins Complications
Sometimes, extremely painful ulcers may form
on the skin near varicose veins, particularly near the ankles. Ulcers
are the result of long-term "water
logging" of these tissues, caused by increased pressure of blood within
affected veins. Brownish pigmentation usually precedes the development
of an ulcer. Ulcers require urgent medical attention.
Treatment for Varicose Veins
Fortunately, treatment usually doesn't mean a
hospital stay or a long, uncomfortable recovery. Less invasive techniques
generally allow varicose veins to be dealt with on an outpatient basis.
Self-help measures — such
as exercising, losing weight, not wearing tight clothes, elevating your
legs and avoiding long periods of standing or sitting — can ease
pain and prevent varicose veins from getting worse. Varicose veins that
develop during pregnancy generally improve without medical treatment
within three months after delivery.
If your varicose veins don't respond to self-help or
if they're more severe, your doctor may advise one of these treatments:
- Sclerotherapy. In this procedure, your doctor injects small- and
medium-sized varicose veins with a solution that scars those veins.
The process closes the veins, forcing your blood to reroute to healthier
veins. In a few weeks, treated varicose veins should fade. Although
the same vein may need to be injected more than once, sclerotherapy
is effective if done correctly. In addition, a new and improved type
of sclerotherapy, called microsclerotherapy, uses improved solutions
and injection techniques that increase the success rate for removal
of spider veins. Sclerotherapy doesn't require anesthesia and can be
done in your doctor's office.
- Laser surgeries. Doctors are using laser procedures more commonly
to close off smaller varicose veins and spider veins, especially on
the upper body and the face. In the past, varicose veins in the legs
didn't respond consistently to laser treatments, and some doctors doubted
whether laser surgery actually worked. Now, however, new technology
in laser treatments can effectively treat varicose veins in the legs.
Laser surgery works by sending strong bursts of light onto the vein,
which makes the vein slowly fade and disappear. No incisions or needles
are used.
- Catheter-assisted procedures. In one of these treatments, your doctor
inserts a thin tube (catheter) into an enlarged vein and heats the
tip of the catheter. As the catheter is pulled out, the heat destroys
the vein by causing it to collapse and seal shut. This procedure is
usually done for larger varicose veins. Other catheter-assisted methods
use a blade to destroy varicose veins or radio waves to close them.
- Vein stripping. This procedure involves removing a long vein through
small incisions. This is an outpatient procedure for most people. Removing
the vein won't affect circulation in your leg because veins deeper
in the leg take care of the larger volumes of blood.
- Ambulatory phlebectomy (fluh-BEK-to-me). Your doctor removes smaller
varicose veins through a series of tiny skin punctures. Local anesthesia
is used in this outpatient procedure. Scarring is generally minimal.
- Endoscopic vein surgery. You might need this
operation only in an advanced case involving leg ulcers. Your surgeon
uses a thin video camera inserted in your leg to visualize and close
veins. Only small incisions are needed.
When it comes to treatment options for varicose
veins, it pays to be a cautious health consumer. Advertisements claiming "unique," "permanent" or "painless" methods
to remove varicose veins may be appealing, but they may not actually
measure up to those claims. Before undergoing any procedure, ask your
doctor about any health risks and possible side effects.
You may want to inquire about treatment costs, as well. Most insurance
policies don't cover the expense of elective cosmetic surgery for varicose
veins. However, in many cases, if you have signs or symptoms such as
swelling and bleeding, insurance may cover the treatment.
Current treatments for varicose veins and spider veins are highly successful.
However, it's possible that varicose veins can recur.
Prevention for Varicose Veins
There's no way to completely prevent varicose veins. But improving your
circulation and muscle tone can reduce the risk of developing varicose
veins or getting additional ones. To improve circulation and muscle tone,
follow these tips:
- Exercise. Get your legs moving. Walking is a great way to encourage
blood circulation in your legs. Your doctor can recommend an appropriate
activity level for you.
- Control your weight. Shedding excess pounds takes unnecessary pressure
off your veins.
- Watch what you wear. Avoid high heels. Low-heeled shoes work calf
muscles more, which is better for your veins. Don't wear tight clothes
around your waist, legs or groin. Tight panty-leg girdles, for instance,
can restrict circulation.
- Elevate your legs. To improve venous circulation, take several short
breaks daily to elevate your legs above the level of your heart. For
example, lie down with your legs resting on three or four pillows.
- Avoid long periods of sitting or standing. Make a point of changing
your position frequently to encourage blood flow. Try to move around
at least every 30 minutes.
- Don't sit with your legs crossed. This position
can aggravate circulation problems.
Self Care
Wearing compression stockings is often the first approach to try before
moving on to other treatments. Compression stockings are worn all day
long. They steadily squeeze your legs, helping veins and leg muscles
move blood more efficiently. The amount of compression varies by type
and brand.
Some people think of compression stockings as being uncomfortable and
unstylish, but their negative fashion reputation is no longer deserved.
Stockings today come in a variety of strengths, styles and colors. With
the variety offered, you're likely to find a stocking that you're comfortable
wearing.
Compression stockings are sold at most pharmacies and medical supply
stores. Prices vary. Prescription-strength stockings also are available.
When purchasing compression stockings, make sure that they fit properly.
Using a tape measure, you or your pharmacist can measure your legs to
ensure you get the right size and fit according to the size chart found
on the stocking package. Compression stockings should be strong but not
necessarily tight. If you have weak hands or arthritis, getting these
stockings on may be difficult. There are devices to make putting them
on easier.
Complementary and alternative medicine for varicose
veins
You may be tempted to try one of the many herbal supplements that claim
to prevent varicose veins or get rid of them. The active ingredient in
most of the products is horse chestnut. It may be possible that herbal
supplements will beneficially affect some signs and symptoms of varicose
veins, but it's not likely that herbal supplements will do much to eliminate
the veins or relieve the pain they might cause. Additionally, there are
concerns about the purity of herbal supplements because the Food and
Drug Administration doesn't regulate these products as closely as they
do prescription medications.
