Definition
Varicose veins, sometimes referred to as spider veins, is the stretching and bulging of veins visible beneath the skin's surface. In a properly functioning extremity, arteries carry blood from the heart to all parts of the body, veins in return pump or bring that blood back up to the heart, according to the Vein Center for Excellence in Gurnee, Illinois, a medical practice that treats varicose veins. When the veins are stretched and bulging, they lose their capacity to transport blood correctly and varicose veins are the result. Varicose veins are most commonly seen in the legs, but can also appear on the face, such as the cheeks.
Hereditary
The single biggest factor influencing varicose veins is genetics.
Pregnancy
Pregnancy can exacerbate the condition or bring the condition to light. With increased blood flow and pressure on a women's legs during pregnancy, varicose veins can result.
Hormonal
The alteration of hormones during pregnancy can weaken the vein walls in the legs, increasing the chance of varicose veins. Other hormonal changes that can spur varicose veins include menopause, contraceptives, menstruation, puberty or hormonal replacement therapy.
Extended Periods of No Movement
Sitting for long periods of time, such as a desk job, increases the likelihood of varicose veins. The inactivity does not create the opportunity for appropriate circulation within the legs.
Standing for Long Periods of Time
Paradoxically, standing and being on your feet for long periods of time can also increase your likelihood of varicose veins. As an individual stands, the blood pools in the veins, the longer the blood pools, the more the vein is stretching to accommodate the increased amount.
There is some question if any link between running and varicose veins exists. Overall, walking and running are good for your legs as they help create circulation and prevent any blood from pooling or stagnating in your veins. However, extended periods of running, such as continued marathon training, or running for long periods of time on hard surfaces can contribute to enlarged veins resulting in varicose veins.
