why do veins bulge in the hands

Bulging veins in the hands are common signs of aging; but a variety of other conditions could be the cause, some of them potentially harmful. However, in many cases, particularly those having to do with teenagers, the cause is something more benign, such as excessive activity. Due to the potential risk involved, consult a doctor to rule out a more-serious disorder. Veins are responsible for taking deoxygenated blood back to the heart and lungs to be reoxygenated. Unlike arteries, veins have valves in them that control the flow of blood. When veins bulge -- on the hand or anywhere else in the body -- it is because the blood is pooling in the vein, either due to a problem with the vein itself or an underlying condition. Bulging veins are more common on the leg, but they can occur anywhere on the body. If a teen is active in sports, such as lifting weights, it can cause the veins in the hand to bulge temporarily, which is usually not a cause for concern.

Other causes that could be to blame include excessive inactivity, obesity, pregnancy, high blood pressure, structural problems with the veins, injury, and thrombophlebitis, a swelling caused by a blood clot. It could also be a hereditary condition, which could be more noticeable in a thin teenager. If bulging veins in the hand is accompanied by other symptoms, an underlying medical condition is more likely the cause. Symptoms that accompany bulging hand veins can include pain, warmth and redness in the affected area, which is common in thrombophlebitis. If diabetes is the cause, symptoms can include slow-healing wounds and ulcers on the skin. Veins that bulge as the result of a structural problem in the veins are usually always swollen and slightly engorged. Even if no other symptoms are present other than bulging veins, it does not rule out a more serious medical condition. Bulging veins in a teen's hands are not always a cause for concern, but a doctor should be consulted to rule out an underlying medical disorder.

Treatment for the condition will depend on the underlying cause. If the cause is genetics, no treatment is usually given, although cosmetic procedures are available to remove the veins. Bulging hand veins accompanied by symptoms of infection -- including redness and swelling in the affected veins, pain, a pulling sensation or bleeding from the vein -- require immediate medical attention.
Both exercise and aging can cause the veins in your hands to bulge, but for different reasons. In either circumstance, the bulging veins are probably normal. If the appearance of the veins bothers you, you can seek treatment to diminish the protrusion of the veins. In some circumstances, however, bulging veins are caused by vascular disease, and you will need to seek medical treatment to treat the cause of the bulging veins. Veins often bulge during exercise but then diminish once you are at rest.

During exercise, arterial blood pressure increases, forcing the plasma from the blood to pool around the muscles and causing the muscles to swell and harden. As a result, the veins are pushed toward the surface of the skin, making them appear more prominent. The appearance of the veins in your hands may also become more pronounced if you lift weights because your muscles are larger and harder, which also works to push the veins to the surface of the skin. As you get older, the skin becomes thinner and less elastic, causing it to settle over the veins and fine bones in your hands. As a result, your veins may appear more prominent. Despite their bulging appearance, the veins themselves did not change, and prominent veins due to loss of skin elasticity do not indicate an underlying medical problem. These veins should not be confused with varicose veins or other vascular problems because their appearance is only a cosmetic issue.

If you are dissatisfied with the appearance of your hands, you can undergo sclerotherapy. During sclerotherapy, the physician will inject the prominent veins in your hands with a solution that will cause the vein to collapse. This will lessen the bulging appearance of the vein, and reroute the blood to deeper veins that are less noticeable. Your veins may stretch with age, which makes the valves that prevent the blood from flowing backward from working efficiently. When the blood is not prevented from flowing backward into your veins, the veins may become enlarged and painful, causing your hands to swell. These are known as varicose veins. Unlike for skin stretching due to aging, you need to seek medical attention for varicose veins because they may become debilitating over time, or they may occur along with more serious symptoms of vascular disease such as blood clotting disorders.
