What are varicose veins?
Varicose veins, also known as varicoses or varicosities, occur when your 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. 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.
Causes of varicose veins:
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.
Symptoms of varicose veins
The primary symptoms of varicose veins are highly visible, misshapen veins, usually on your legs. You may also have pain, swelling, heaviness, and achiness over or around the enlarged veins. In some cases, you can develop swelling and discoloration. In severe cases, the veins can bleed significantly, and ulcers can form.
Risk of other Circulatory Problems:
- Cramps in legs.
- Etching and dryness in lower legs and ankle.
- Minor swelling in feet and ankles.
