Varicose Veins: What You May Not Know
Varicose veins are enlarged, often twisted vessels that form near the surface of the skin. They are usually blue or dark purple in color and can bulge out of the skin, giving them a ropelike appearance. Approximately 15-25% of adults in the United States have varicose veins, with the condition affecting far more women than men. Keep reading to learn more about varicose veins, including causes, symptoms, diagnosis, and treatment.
Causes of Varicose Veins
In a healthy circulatory system, one-way valves inside the veins make sure that the blood is well-circulated throughout the body. These valves keep the blood flowing in one direction – toward the heart.
When these valves become weakened or damaged, the blood moves in the opposite direction, creating reverse blood flow. This puts pressure on the walls of the veins, causing them to swell and twist. This unwanted pressure results in varicose veins
Symptoms of Varicose Veins
Varicose veins have a number of uncomfortable symptoms, including:
- Pain or aching in the legs
- Swelling in the legs
- Burning or itching around the veins
- Throbbing or cramping in the legs
- Heavy feeling in the legs
Diagnosis
A doctor can diagnose varicose veins by observing the appearance of your legs. An ultrasound test may also be done to check for any blood clotting.
Treatment
The most commonly used treatments for varicose veins include:
- Compression stockings: These support hose help to improve the circulation of blood in the legs.
- Sclerotherapy: An injectable medicine is used to close the affected vein, which will be absorbed into the body.
- Endovenous laser treatment: A laser is used to heat and close off the varicose veins.
- Surgery: During a procedure, the damaged veins are removed and healthy veins are used to carry the blood.
