Varicose Veins
Approximately 25 million Americans have varicose veins.
For some, they're simply a cosmetic concern. But for
many others, varicose veins can cause significant pain
and discomfort. Sometimes they even lead to more serious
problems. Exercise does not cause varicose veins. In
fact, exercise may help prevent the problem, while excessive
sitting or standing is more likely to aggravate it.
The underlying cause is malfunction of the
valves in the veins that normally allow blood to flow
only toward your heart. If the valves are defective,
blood may pool in the veins, causing them to dilate
and become varicose (meaning twisted and swollen).
Most varicose veins develop in the legs near the surface
of the skin; they are more common in women than in men.
Factors that may contribute to their development include
an inherited tendency to defective valves, increased
pressure in the veins during pregnancy, obesity and
past episodes of clots in the veins (thrombophlebitis).
Fortunately, treatment usually doesn't mean a hospital
stay or a long, uncomfortable recovery. New and less
invasive techniques generally allow varicose veins to
be dealt with on an outpatient basis.
Arteries carry blood from your heart to the rest of
your body tissues. Veins return blood from 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 the natural effect of gravity. This is accomplished
with the help of muscle contractions in your lower legs
(which act as pumps), and elastic vein walls with tiny
one-way valves in the veins. The valves open as blood
flows toward your heart and close to stop blood from
flowing backwards.
As you get older, though, your veins can lose elasticity,
causing them to stretch and balloon out. When that happens,
the one-way valves may not function properly. Blood
that should be moving toward your heart may flow backward,
stretching the walls of the veins that may then become
visible as varicose veins (varicose comes from the Latin
root varix for "twisted").
Varicose veins usually appear between ages 30 and 70
and progressively get worse. Frequently they're hereditary.
Women are more likely than men to have them, in part
because female hormones tend to relax vein walls. Other
contributing factors can include pregnancy, illness,
injury and being overweight.
You may have symptoms even before varicose veins appear.
Symptoms can 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.
Bulging varicose veins are often accompanied by itching
around the vein. In more advanced stages, open sores
(ulcers) may develop around the ankle area. Ulcers represent
a severe form of vascular disease and require immediate
attention.
In addition, 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.
Unfortunately, once varicose veins start, they don't
get better on their own. The best advice if you have
them (even small ones), or suspect you have them, is
see your vascular specialist. Your doctor may first
recommend that you wear compression stockings. In addition,
lifestyle recommendations might include:
- 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.
- Weight control — Shedding excess pounds takes
unnecessary pressure off your veins.
- Watching what you wear — Avoid high heels.
Low-heeled shoes work calf muscles more, which is
better for veins.
- Elevating your legs — Take three or four 10-
to 15-minute breaks daily to elevate your legs above
the level of your heart (for example, by lying down
with your legs resting on three or four pillows) as
well as elevating your legs at night while sleeping.
Avoiding long periods of sitting or standing —
Make a point of changing your
position frequently to encourage blood flow. Wearing
of compression hose to assist in returning the blood
to the heart and decrease the pressure in varicose veins.
If these methods fail to bring relief of symptoms,
newer methods of treating the refluxing greater saphenous
vein (large vein in the inner part of your leg) have
been very effective. Unlike vein stripping, these methods
are relatively painless, done as an outpatient, and
result in practically no downtime. Using either a laser
probe or a radiofrequency ablation probe, the vein can
be collapsed resulting in complete resolution of symptoms
in many cases. In addition, bulging varicosities will
also resolve once the main refluxing saphenous vein
is treated producing much cosmetic improvement.
