Why do veins come out?

Answer 1

There are a couple of reasons why:

When exercising they become dilated because of increased physical activity; basically the muscles need more oxygen. The heart is beating faster and it is easier for the heart to pump blood through a bigger pipe (less resistance)

When you are getting out of a hot tub or shower it's one of the body's ways of cooling the body internally. This can also be applied to exercising. Blood circulated to the skin where sweat evaporates. That evaporation cools off the blood at the surface and then circulates within the body. It is one of the reasons you may see a paramedic put a heat pack on someones hand in the winter to get the veins to pop up to start and IV.

The other reason is that you have high blood pressure.

Answer 2

A varicose vein is a large and winding blood vessel. These twisted, swollen and bulging vessels are commonly found on the insides of the legs and at the back of the calf and are visible on the surface.



They form because the blood flow is too slow and the vein fills up with the excess. Another possible reason is that the valves in the vein are not working properly so the blood drops down from gravity and collects in the veins of the legs. Nearly 15% of all adults are affected. Varicose veins are more likely to occur in women than in men.



Leg veins become bigger, blue and twisted. Most people feel some pain in the area, with swelling, and a constant itch. Blood pooling in the veins means the tissues don't get enough blood and nutrients, causing the skin to become thin, hard, dry and discolored.


Obesity and hormonal changes during pregnancy contribute to the formation of varicose veins.


Superficial vein thrombosis can happen on the surface.causing thrombophlebitis. Deep vein thrombosis (DVT) is sometimes associated with varicose veins
In this instance, a venous clot can form giving you the sensation of a sore, full, knotted area. If this sore area becomes red and extremely sore to the touch making it painful to walk; don't delay - see your doctor as soon as you can. DVT can cause the clots to loosen and travel thru the bloodstream into the lungs causing a life- threatenig condition of pulmonary embolism.
