Topic Definition
- Varicose Veins
Varicose veins are veins that have become enlarged, swollen, and twisted, most often appearing in the legs, though they can develop elsewhere in the body. They form when the small one-way valves inside a vein weaken or fail, allowing blood to flow backward and pool instead of returning smoothly to the heart. This backward flow, known as venous reflux, raises pressure inside the vein and causes the visible bulging and discoloration many people recognize. Varicose veins are larger than the related reticular veins and spider veins (telangiectasias), which share the same underlying valve problems but differ in size and location. Common contributing factors include aging, pregnancy, being overweight, prolonged standing or sitting, and a lack of exercise. While often a cosmetic concern, varicose veins can also bring aching, heaviness, swelling, and skin changes that benefit from medical care.
Overview
What are Varicose Veins?
Varicose veins are veins that have become enlarged, swollen and twisted. They most often appear in the legs, although they can occur elsewhere; Hemorrhoids are a type of varicose vein. Veins have small one-way valves that keep blood flowing toward the heart. When these valves weaken, blood can flow backward and pool in the vein (venous reflux), so the vein stretches and bulges. Varicose veins are distinguished from reticular veins (small blue veins) and telangiectasias (spider veins), which involve the same valve problems, by their larger size.
Varicose and spider veins are very common, especially in women and older adults. Risk factors include older age, a family history of vein problems, pregnancy, being overweight, standing or sitting for long periods, and a past blood clot in the leg. For many women, the first signs of varicose veins appear during pregnancy.
Signs and Symptoms of Varicose Veins
Many varicose veins cause no symptoms other than their appearance. Others cause:
- Aching, heavy or tired legs, often worse at the end of the day or after standing.
- Swelling of the ankles, especially in the evening.
- Itching around the veins, and muscle cramps or restlessness in the legs.
- Brownish discoloration of the skin near the ankles (stasis pigmentation).
- Red, dry, itchy skin (stasis dermatitis or venous eczema).
- Hardening and shrinking of the skin above the ankle (lipodermatosclerosis), or white scar-like patches (atrophie blanche).
- Minor injuries that bleed more than normal or heal slowly, and in severe cases open sores (venous ulcers) near the ankle.
Restless legs syndrome is common in people with varicose veins and other chronic venous insufficiency. See a doctor if a vein becomes painful, red, warm and hard, if the leg swells suddenly, or if a vein bleeds, since these can be signs of a blood clot or other complication.
Diagnosis
Doctors can usually see varicose veins on examination. A duplex ultrasound scan, a painless test that uses sound waves to show the veins and the direction of blood flow, is used to check the valves and look for blood clots before treatment. Older tests that inject a contrast dye into the veins (venography or phlebography) are now rarely needed.
Home Care and Self-Help
Phlebology is the branch of medicine devoted to diagnosing and treating vein disorders. For many people, simple measures ease symptoms and slow the progress of varicose veins:
- Wear graduated compression stockings.
- Keep to a healthy weight.
- Walk or do other regular exercise, such as swimming, cycling or aerobic exercise, to strengthen the calf muscles that pump blood back to the heart.
- Avoid standing or sitting for long periods, and move around or flex your ankles often.
- Raise your legs above the level of your heart for 15 to 30 minutes several times a day.
- Eat a diet high in fiber to prevent constipation, and limit salt to reduce swelling.
- Avoid tight clothing around the waist, groin and legs.
Some studies suggest that horse chestnut seed extract may ease leg pain and swelling for a short time, but check with a doctor before taking herbal products, especially if you take blood thinners.
Medical Treatments for Varicose Veins
Most treatments today are minimally invasive and are done in a doctor's office with local anesthesia, and most people return to normal activities within a day or two:
- Endovenous thermal ablation: a thin catheter is placed in the faulty vein, and laser or radiofrequency energy heats and seals it shut. This is now the most common treatment for large varicose veins.
- Medical adhesive (vein glue): a special glue is injected through a catheter to close the vein.
- Sclerotherapy: a solution (sclerosant) is injected into spider veins and small varicose veins, causing them to scar shut and fade. Foam sclerotherapy can treat larger veins. Several sessions may be needed, and side effects can include bruising, brown marks along the treated veins, and new tiny red veins (matting), which usually fade with time.
- Ambulatory phlebectomy: bulging veins near the surface are removed through tiny cuts in the skin.
- Vein stripping and ligation: the vein is tied off and removed through incisions. This older surgery is now used much less often.
After treatment, blood flows through other healthy veins. Compression stockings are often worn for a time after a procedure. Because new varicose veins can form, healthy habits remain important. If you have varicose veins, ask your health care provider about your treatment options.
Frequently Asked Questions
Are varicose veins dangerous?
Varicose veins are often a cosmetic concern, but in some cases they can lead to complications such as skin ulcers, bleeding, or blood clots, so it is wise to seek medical advice if symptoms develop.
Do varicose veins go away on their own?
Varicose veins do not usually disappear on their own, though symptoms can be eased with compression stockings, exercise, leg elevation, and weight management, and persistent veins may need medical treatment.
What is the difference between varicose veins and spider veins?
Varicose veins are larger, raised, and often twisted, while spider veins are smaller, flatter, and appear as thin red or blue lines just beneath the surface of the skin.
Can men get varicose veins?
Yes, men can develop varicose veins, although the condition is more common in women, and risk factors such as age, weight, and prolonged standing affect both men and women.
Does crossing your legs cause varicose veins?
Crossing the legs does not directly cause varicose veins, but sitting for long periods and habits that restrict circulation can contribute to leg discomfort and worsen existing vein problems.
When should someone see a doctor about varicose veins?
A person should see a doctor if varicose veins cause pain, swelling, skin changes, bleeding, or sores, or if the appearance of the veins is causing significant distress.
Can exercise help prevent varicose veins?
Regular low impact exercise such as walking, swimming, and cycling promotes healthy circulation and can help reduce the risk of developing varicose veins and ease mild symptoms.
Do compression stockings help varicose veins?
Compression stockings squeeze the legs to help blood flow back toward the heart, easing aching and swelling. They can relieve symptoms but do not make existing varicose veins go away.
