Varicose veins are swollen, twisted veins that typically appear on the legs and feet. These enlarged veins often look blue or dark purple and may bulge out beneath the skin. Varicose veins develop when faulty vein valves allow blood to flow backward and pool, putting pressure on the vein walls.
While for some, varicose veins are mainly a cosmetic issue, for others they cause significant discomfort, aching, and in severe cases, more serious health complications.
What Are Varicose Veins?
Varicose veins occur when veins become enlarged and overfilled with blood due to weakened or damaged valves. These veins are usually located near the surface of the skin and most commonly appear on the legs, where blood circulation faces the force of gravity.
Common Symptoms of Varicose Veins
Varicose veins don’t always cause pain, but visible signs and symptoms may include:
-
Twisted, bulging veins that resemble ropes or cords.
-
Veins that appear blue, dark purple, or skin-colored depending on skin tone.
-
A heavy, aching sensation in the legs, especially after standing or sitting for long periods.
-
Swelling, muscle cramps, burning, or throbbing in the lower legs.
-
Itching or skin discoloration around the affected veins.
-
Spider veins — small, web-like clusters of veins closer to the skin surface — may also develop.
When to See a Doctor
If you experience persistent leg pain, swelling, or are concerned about the appearance of your veins, it’s best to consult a healthcare professional. Timely medical advice can prevent the progression of varicose veins and help avoid complications like ulcers or blood clots.
What Causes Varicose Veins?
Veins rely on small valves to help blood return to the heart. When these valves weaken or become damaged, blood can backflow and collect in the vein, causing it to stretch and swell. This often leads to the visible and uncomfortable signs of varicose veins.
Risk Factors for Varicose Veins
Several factors can increase your risk of developing varicose veins:
Family history: If your parents or siblings have varicose veins, you’re more likely to develop them.
Age: Aging causes natural wear and tear on vein valves.
Gender: Women are more prone to varicose veins due to hormonal changes during pregnancy, menstruation, and menopause.
Pregnancy: Increased blood volume during pregnancy enlarges veins, especially in the legs.
Obesity: Excess weight adds pressure on veins.
Prolonged sitting or standing: Lack of movement can lead to poor circulation.
Potential Complications
Although complications are rare, untreated varicose veins can lead to:
-
Leg ulcers: Painful sores that develop near the ankle, often requiring medical treatment.
-
Blood clots: Swollen, painful legs may indicate deep vein thrombosis (DVT).
-
Bleeding: Varicose veins close to the skin can sometimes burst, causing minor but noticeable bleeding.
-
Chronic swelling: Long-standing varicose veins may lead to leg edema.
How to Prevent Varicose Veins
While you may not always be able to prevent varicose veins, adopting healthy habits can reduce your risk:
-
Avoid prolonged sitting or standing.
-
Exercise regularly to improve leg circulation.
-
Maintain a healthy weight.
-
Elevate your legs when resting.
-
Wear compression stockings if recommended by your doctor.
-
Eat a high-fiber, low-sodium diet to reduce pressure on veins.
Treatment Options for Varicose Veins
Managing varicose veins often starts with lifestyle changes:
Exercise regularly to enhance blood flow.
Elevate your legs when sitting or lying down.
Wear compression stockings to help veins move blood efficiently.
When self-care isn’t enough, your doctor might recommend medical procedures, such as:
Sclerotherapy: A solution is injected to close off small veins.
Laser treatments: Light energy fades smaller varicose veins.
Endovenous ablation therapy: Uses heat to seal off larger veins.
Vein stripping and ligation: Surgically removing or tying off veins.
Microphlebectomy: Small incisions are made to remove visible veins.
