What causes varicose veins, gravity?

Gravity IS involved! You are right! gravity alone will not cause varicose veins unless you also have vein insufficiency or improperly functioning valves of your veins which then allow blood to pool in your veins and increase pressure in your leg veins. This increased pressure causes the veins to get thicker and bulge.
Newton's thick skin. An apple hit newton on the head. If newton had sat under apple trees too often, he would need thick skin! and he had better have strong veins too! lucky people inherit genes for strong veins, but 15% of people don't. Gravity pressurizes vein walls and the weaker veins can't take the stress- they give out and dilate! one can't change genetics, but fight back with lifestyle and compression socks!
Not gravity. Incompetent valves in the venous system of the leg, especially the saphenous vein, lead to varicose veins. Of course, they would not occur except that gravity then pulls the blood back down the veins.
Bad valves. Varicose veins are caused by valve problems that allow blood from deep high-pressure veins to enter low-pressure veins just under the skin. These veins enlarge, (varicose), leak fluid through the walls (swelling), letting blood through (discoloration) and finally nutritious arterial blood cannot enter an area of the skin resulting in ulcers. It is treated by laser ablation.
Not exactly. The cause of varicose veins is an inherited tendency for you to have weak vein walls and valves in your veins that either don't work properly or didn't form in the first place. As a result, gravity makes blood flow backwards in the affected veins. This produces too much pressure in the veins and they enlarge, becoming what we call varicose. The root cause, though, is heredity, not gravity.

What is the cause of Varicose Veins?

Loss of valves. Varicose veins are induced by pressure within the venous system. When standing there is a tendency for pressure to build up in the veins or the legs returning blood to the heart. Because of the passive return of venous blood , the vessels contain valves which tend to hold the blood as it is forced back into the returning circulation. Loss of valve function causes the development of varicosities. Read more...
Stretchy collagen. The biggest factor for developing varicose veins is heredity. People with genes for collagen which is more stretchy pass this on to their children. The type of collagen make the valves and the vein walls dilate in response to pressure which set in motion a cascade of events that results in varicose veins. Dilated twisted veins which do not have valves to circulate the blood properly[ to the heart] Read more...

Leaking valves. Varicose veins are a very common problem and they are due to leaking valves (called reflux) usually in the saphenous veins. Think of your veins like a tree with the trunk being the saphenous vein and the branches being the varicose veins. A venous reflux ultrasound will make the diagnosis. Common causes of this are hereditary, aging and pregnancies in women. They are treatable with a laser. Read more...
Multiple. There are multiple causes that can include family history, obesity, trauma, prolonged standing, prior clots (phlebitis), pregnancies, age, etc. There are both medical and surgical treatments that are both safe and effective. Read more...
Genetics / reflux. Usually varicose vein disease is genetically acquired, especially when developing in someone of your age. Other factors such as female gender, hormones, being overweight, pregnancies, trauma, or clots can precipitate or worsen the disease. Ultrasound of the legs often reveals underlying venous reflux disease in a vein called the saphenous vein which causes the development of the surface veins. Read more...
Venous reflux. Blood should only go up in your leg veins. In order to prevent the blood from refluxing the veins have little valves. When they become faulty the blood refluxes and varicose veins form. Read more...
Risk factors/causes. Age- the older you get the more the veins become elastic. Pregnancy- due to the increased blood flow and the increased pressure from the enlarged uterus.

Varicose veins. These are abnormal veins of the lower extremity. This could be spider veins, which is more common in women secondary to hormonal changes. The other possibility of a larger varicose veins which are result of reflux of blood flow back down the leg in the superficial vein system. These are the bulging veins, which more frequently start at the lower portion of the leg and associated with swelling, Read more...

Could using an eliptical cause varicose veins?

No. The risk factors for development of vv are heredity, aging, pregnancy, lifestyle with prolonged standing/sitting, obesity. Exercise, elevation of legs, and compression hose are good conservative ways to help cope with the symptoms of leg swelling, pain, seen with vv. Read more...
Maybe. I agree that the risk factors for development of varicose veins as above. In heredity cases, patients are born with incompetent one way valves with prevent the venous blood from flowing backward down the extremities. Increased abdominal pressure with forceful exercise can cause the superficial veins to be under extreme pressure due to the lack of vavular function. Consider compression stockings. Read more...
NO. Exercise is actually healthy for your circulation & there is no evidence that cardiovascular exercise (including use of eliptical) will cause or increase the likelihood of developing varicose veins. These veins are a genetic problem with valves within the leg veins & they will develop over time regardless of activity level or exercise. Pregnancy, obesity, and trauma can make them come on sooner.

Multiple symptoms. Varicose veins can cause many symptoms including pain, aching, swelling, cramping , heaviness, tired legs or even restless legs. When there is pain it is often times associated with a clot in the vein (superficial phlebitis). The most common symptom of varicose veins is aching of the legs. It would be prudent to see a vein specialist for a full venous evaluation with a venous ultrasound. Read more...
Yes. Varicose veins are the result of faulty vein valves within the visible surface veins as well as the underlying "feeder" vein that is causing them. The faulty valves lead to constant stretching & pressure buildup in the veins that can lead to pain even when at rest. When standing the pressure & symptoms typically worsen. If the veins get inflamed with phlebitis there can also be increased pain. Read more...
