Varicose Vein & Vein
Treatment FAQ
What are Varicose Veins?
Varicose veins are bulging veins that are abnormally dilated. Varicose veins are typically 3mm or larger in diameter. These dilated veins may be
only cosmetic, or can cause pain, leg heaviness, fatigue, restless legs, and leg swelling. Severe varicose veins may decrease circulation while causing changes in skin, inflammation, phlebitis, or even ulceration of the lower leg.
Normal veins have one-way valves that keep blood flowing toward the heart and lungs. A varicose vein has valves that are not functioning properly. Because the valves are not functioning the blood tends to pool in the vein, thereby causing an increased pressure on the wall of the vein. This refluxing of flow then causes the vein to dilate as well as other connecting veins nearby.

“Spider veins” are small red, blue or purple veins that commonly appear on the upper thighs, calves and ankles. It is estimated that at least one third of the adult female population is affected by this common problem. People often seek treatment for cosmetic reasons. Spider veins can, however, cause
physical symptoms depending on the severity. These symptoms may include aching, heaviness, stinging sensations, itching, and night cramps.
Spider veins may be isolated or associated with “feeder” veins. They can also be associated with larger underlying malfunctioning veins. It is always recommended to rule out the underlying cause if there are associated symptoms with spider veins prior to treatment.
Typical treatments for spider veins are Sclerotherapy and Compression Stockings.

There are many causes of varicose veins. The following factors may play a
part in the development of varicose veins and spider veins.
- Heredity – There is a significant relationship between heredity and the development of varicose veins and spider veins.
- Age – The development of varicose veins and spider veins may occur at
any age but usually occurs between the ages of 18 and 35 years.
- Gender – Females are affected approximately four
times more frequently than males.
- Pregnancy – Pregnancy is a common factor contributing to the formation
of varicose veins and spider veins. The most important factor is
circulating hormones that relax the vein walls. There is also a significant increase in the blood volume during pregnancy which tends to distend
veins, causing valve dysfunction which leads to blood refluxing
(flowing backwards) into veins. Additionally, later in
pregnancy, the enlarged
uterus can contribute by
causing higher vein pressure
leading to dilated veins. Varicose
veins that develop
during
pregnancy may spontaneously improve or even
disappear
a few
months
after birth.
- Lifestyle / Occupation – People who are involved with prolonged standing
or sitting with their daily activities
have an increased risk of developing
varicose veins
simply by the gravity forces of the blood continuously
pressing against the closed valves causing the valves
to fail, and
leading to distention in the veins.
A few lifestyle factors that may
contribute to developing
varicose veins:
- Prolonged standing or sitting
- Number of pregnancies
- Birth control pills / Hormone replacement therapy
- Obesity
- Chronic constipation
- Severity of menstrual cycles
- Heat
- Sedentary lifestyle

Since there are multiple causes of varicose veins, prevention is somewhat
difficult to determine. Below are some tips that may help in the prevention of both varicose and spider veins.
- Elevate your legs when possible.
- Exercise daily. Walking, climbing stairs, cycling and swimming help with the calf muscle pump action to prevent blood from pooling causing varicose veins.
- Move your legs frequently. Flexing your ankles periodically will also help.
- Avoid sitting without moving legs for extended periods of time.
- Wear support compression hose. These hose tend to reduce pooling and pressure on leg veins. They may also reduce the risk of forming a deep vein blood clot.
- Maintain your ideal body weight to reduce pressure on your legs.
Avoid prolonged sitting and standing.
- Avoid excessive heat on your legs, such as hot tubs
and hot baths.
