Condition 101 About Varicose Veins

What is the definition of Varicose Veins?

Varicose veins are swollen, twisted, and enlarged veins that you can see under the skin. They are often red or blue in color. They most often appear in the legs, but can occur in other parts of the body.

What are the alternative names for Varicose Veins?


What are the causes for Varicose Veins?

Normally, one-way valves in your leg veins keep blood moving up toward the heart. When the valves do not work properly, they allow blood to back up into the vein. The vein swells from the blood that collects there, which causes varicose veins.

Varicose veins are common, and affect more women than men. They do not cause problems for most people. However, if the flow of blood through veins becomes worse, problems such as leg swelling and pain, blood clots, and skin changes may be present.

Risk factors include:

  • Older age
  • Being female (hormonal changes from puberty, pregnancy, and menopause can lead to varicose veins, and taking birth control pills or hormone replacement can increase your risk)
  • Being born with defective valves
  • Obesity
  • Pregnancy
  • History of blood clots in your legs
  • Standing or sitting for long periods of time
  • Family history of varicose veins

What are the symptoms for Varicose Veins?

Symptoms of varicose veins include:

  • Fullness, heaviness, aching, and sometimes pain in the legs
  • Visible, swollen veins
  • Smaller veins that you can see on the surface of the skin, called spider veins.
  • Thigh or calf cramps (often at night)
  • Mild swelling of feet or ankles
  • Itching
  • Restless leg symptoms

If flow of blood through the veins becomes worse, symptoms may include:

  • Leg swelling
  • Leg or calf pain after sitting or standing for long periods
  • Skin color changes of the legs or ankles
  • Dry, irritated, scaly skin that can crack easily
  • Skin sores (ulcers) that do not heal easily
  • Thickening and hardening of the skin in the legs and ankles (this can happen over time)

What are the current treatments for Varicose Veins?

Your provider may suggest that you take the following self-care steps to help manage varicose veins:

  • Wear compression stockings to decrease swelling. These stockings gently squeeze your legs to move blood up toward your heart.
  • DO NOT sit or stand for long periods. Even moving your legs slightly helps keep the blood flowing.
  • Raise your legs above your heart 3 or 4 times a day for 15 minutes at a time.
  • Care for wounds if you have any open sores or infections. Your provider can show you how.
  • Lose weight if you are overweight.
  • Get more exercise. This can help you keep off weight and help move blood up your legs. Walking or swimming are good options.
  • If you have dry or cracked skin on your legs, moisturizing may help. However, some skin care treatments can make the problem worse. Talk to your provider before using any lotions, creams, or antibiotic ointments. Your provider can recommend lotions that can help.

If only a small number of varicose veins are present, the following procedures may be used:

  • Sclerotherapy. Salt water or a chemical solution is injected into the vein. The vein hardens and disappears.
  • Phlebectomy. Small surgical cuts are made in the leg near the damaged vein. The vein is removed through one of the cuts. 
  • If the varicose veins are larger, longer, or more widespread on the leg, your provider will suggest a procedure using such a laser or radiofrequency, which can be done in the provider's office or clinic.

What is the outlook (prognosis) for Varicose Veins?

Varicose veins tend to get worse over time. Taking self-care steps can help relieve achiness and pain, keep varicose veins from getting worse, and prevent more serious problems.

When should I contact a medical professional for Varicose Veins?

Call your provider if:

  • Varicose veins are painful.
  • They get worse or do not improve with self-care, such as by wearing compression stockings or avoiding standing or sitting for too long.
  • You have a sudden increase in pain or swelling, fever, redness of the leg, or leg sores.
  • You develop leg sores that do not heal.
