The heart along with the blood vessels known as the circulatory system. With each heartbeat, oxygen -rich blood is pumped through the arteries throughout the body . Small capillaries located in tissues allow oxygen is released to be used by the cells .

The veins carry deoxygenated blood back to the heart , ready to be pumped to the lungs to receive more oxygen. Veins require special mechanisms to ensure that blood flows against gravity and not backward.

Varicose veins occur most often on the legs and thighs. A person with varicose veins can see them perfectly in your legs, but these distended veins can also cause pain , itching and tired legs , muscle cramps or swollen ankles.

Women are more likely than men to develop varicose veins and those with a family history of the disease are at higher risk .

Risk factors for varicose veins

Going from sitting or standing long periods of time increases the force of gravity on the legs so it is another risk factor . Those who have had a deep vein thrombosis ( blood clot in the deep veins of the leg ) are very likely to develop varicose veins, as part of what is known as "post -thrombotic syndrome."

The high heels change muscle function in the leg and has always believed, incorrectly, that they were a cause of varicose veins . The calf muscle activity actually increases when walking with high heels and this lowers the pressure in the veins of the legs.

Varicose veins can lead to more serious problems and it is important to see your doctor if you experience bruising , skin changes , a suspected clot ( thrombosis ), or a skin wound that will not heal ( ulcers ) .

How to prevent varicose veins

  1. Walk regularly to improve blood circulation in the legs and reduce pressure inside the veins.
  2. Exercise feet and legs if you are sitting for long periods of time. Lift your heels to change the pressure on the toes , for example, or rotate the feet and ankles helps circulation in the legs.
  3. Avoid standing still, as movement helps the return circulation of the veins.
  4. Put your feet up when sitting to reduce pressure in the leg veins and reduce swelling of the ankles .
  5. Consider using socks or light compression socks because they reduce the pressure inside veins and aching legs can improve .
  6. Obesity increases the pressure within the veins of the legs so it is important to stay within a healthy weight.
  7. A healthy diet that includes foods rich in fiber, avoid constipation , as the straining during bowel movements can worsen varicose veins.
