Vein Health is as important a subject as any, because strong, resilient blood vessels of this type are needed to allow the circulatory system to function properly. Veins that become obstructed or whose valves fail can shorten a person’s life or contribute to the development of other issues, some of which can be dangerous themselves. Of all the vein-related problems that people sometimes experience as they get older, however, one of a mostly cosmetic kind tends to attract the majority of attention. While the development of varicose veins can be unpleasant to confront, there are effective means of reversing any such symptoms that appear.
The human circulatory system has a tree-like structure, with major arteries and veins transporting blood directly from and back to the heart, respectively. From these two kinds of trunks emanate smaller, superficial blood vessels of the same basic types, with further branching into capillaries allowing blood to be moved all throughout the body. The beating of the heart sends oxygen-carrying blood rushing out into major arteries with each pulse, with valves closing appropriately under the low pressure that follows. Veins work the same way, except that the valves they are equipped with swing closed in the opposite direction, so that blood whose oxygen has been used up can be returned to the heart.
When the valves lining superficial veins in the legs and elsewhere in the body stiffen over time, they become less capable of springing back with each beat of the heart. Eventually, a vein valve can become stuck open, with the flow of blood no longer being properly controlled, as a result. When this happens, varicose veins will often become evident, since the affected blood vessels start swelling under the pressure of the stagnant, stationary blood they contain.
Fortunately, most such issues tend to be of only cosmetic impact, even if they can seem especially ugly and difficult to bear to those whom they affect. Effective treatment for varicose veins treatments is now widely available, too, with many patients experiencing more or less complete relief.
The most common therapy is a procedure known as sclerotherapy, whereby a special substance is injected directly into affected veins. Over time, the agent causes the targeted veins to harden and close up in a process known as “sclerosis,” after which surrounding tissues naturally absorb them back into the body. The effectiveness of this treatment can also be enhanced through the use of various diagnostic tools that can be helpful for pinpointing problematic veins and better directing the administration of the sclerosis-inducing agent.
