What are varicose
veins?
Varicose veins are twisted, enlarged veins near the surface of the skin. They are most common in the legs and
ankles. They usually aren't serious, but they can sometimes lead to other
problems.
What causes
varicose veins?
Varicose veins are caused by weakened valves
and veins in your legs. Normally, one-way valves in your veins keep blood
flowing from your legs up toward your heart. When these valves do not work as
they should, blood collects in your legs, and pressure builds up. The veins
become weak, large, and twisted.Varicose veins often run in families. Aging also increases your risk. Being
overweight or pregnant or having a job where you must stand for long periods of
time increases pressure on leg veins. This can lead to varicose veins.
What are the
symptoms?
Varicose veins look dark blue, swollen, and
twisted under the skin. Some people do not have any symptoms. Mild symptoms may
include:
- Heaviness, burning,
aching, tiredness, or pain in your legs. Symptoms may be worse after you stand
or sit for long periods of time.
- Swelling in your feet
and ankles.
- Itching over the vein.
More serious symptoms include:
- Leg swelling.
- Swelling and calf pain
after you sit or stand for long periods of time.
