What are varicose veins?
Varicose veins are gnarled, enlarged veins, also known as varicoses or varicosities. Any vein may become varicose, but the veins most commonly affected are those in your legs and feet. That's because standing and walking upright increases the pressure in the veins of your lower body. The veins become enlarged, dilated, and overfilled with blood. Varicose veins typically appear swollen and raised, and have a bluish-purple or red color. They are often painful.
For many people, varicose veins and spider veins — a common, mild variation of varicose veins — are simply a cosmetic concern. For other people, varicose veins can cause aching pain and discomfort. Sometimes varicose veins lead to more-serious problems.
Varicose veins may also signal a higher risk of other circulatory problems. Treatment may involve self-care measures or procedures by your doctor to close or remove veins.The condition is very common, especially in women. Around 25 percent of all adults have varicose veins. In most cases, varicose veins appear on the lower legs.

Symptoms:
Varicose veins may not cause any pain. Signs you may have with varicose veins include:
- Veins that are dark purple or blue in color
- Veins that appear twisted and bulging; often like cords on your legs
When painful signs and symptoms occur, they may include:
- An achy or heavy feeling in your legs
- Burning, throbbing, muscle cramping and swelling in your lower legs
- Worsened pain after sitting or standing for a long time
- Itching around one or more of your veins
- Bleeding from varicose veins
- A painful cord in the vein with red discoloration of the skin
- Color changes, hardening of the vein, inflammation of the skin or skin ulcers near your ankle, which can mean you have a serious form of vascular disease that requires medical attention
Spider veins are similar to varicose veins, but they're smaller. Spider veins are found closer to the skin's surface and are often red or blue.
They occur on the legs, but can also be found on the face. Spider veins vary in size and often look like a spider's web.
Causes of varicose veins
Arteries carry blood from your heart to the rest of your tissues. Veins return blood from the rest of your body to your heart, so the blood can be recirculated. To return blood to your heart, the veins in your legs must work against gravity.
Muscle contractions in your lower legs act as pumps, and elastic vein walls help blood return to your heart. Tiny valves in your veins open as blood flows toward your heart then close to stop blood from flowing backward.
Causes of varicose veins can include:
- Age. As you get older, your veins can lose elasticity, causing them to stretch. The valves in your veins may become weak, allowing blood that should be moving toward your heart to flow backward.
Blood pools in your veins, and your veins enlarge and become varicose. The veins appear blue because they contain deoxygenated blood, which is in the process of being recirculated through the lungs.
- Pregnancy. Some pregnant women develop varicose veins. Pregnancy increases the volume of blood in your body, but decreases the flow of blood from your legs to your pelvis. This circulatory change is designed to support the growing fetus, but it can produce an unfortunate side effect — enlarged veins in your legs.
- Menopause
- Age over 50
- Standing for long periods of time
- Obesity
- Family history of varicose veins
Varicose veins may surface for the first time or may worsen during late pregnancy, when your uterus exerts greater pressure on the veins in your legs. Changes in your hormones during pregnancy also may play a role. Varicose veins that develop during pregnancy generally improve without medical treatment three to 12 months after delivery.
Varicose veins occur when veins aren’t functioning properly. Veins have one-way valves that prevent blood from flowing backward. When these valves fail, blood begins to collect in the veins rather than continuing toward your heart. The veins then enlarge. Varicose veins often affect the legs. The veins there are the farthest from your heart, and gravity makes it harder for the blood to flow upward.
