HOW DO VARICOSE VEINS OCCUR?
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 flow toward your heart then close to stop blood from flowing backward.
The condition is quite common, especially in women. Around 25 percent of all adults have varicose veins.
In most cases, varicose veins appear on the lower legs. There are various options, including some home remedies. In severe cases, a varicose vein may rupture, or develop into varicose ulcers on the skin. These will require treatment.
