Varicose veins are caused by blockages that prevent the blood from flowing freely through the veins. As the blood continues to back up, the veins begin to twist, becoming gnarled and engorged. Varicose veins normally appear as a result of standing or walking for long periods of time. For many people, the look of the veins is the biggest problem. For others it can signify more serious health conditions that involve the heart and circulatory system. Regular exercise and elevating the legs while sitting down may help to prevent varicose and spider veins. A thorough examination will be able to determine what caused the condition in each individual case.
Varicose veins are larger than spider veins and often appear on the legs. Spider veins, on the other hand, are much smaller and can appear almost anywhere on the body. Both occur due to backups and blockages within the veins. While varicose veins are thick, unsightly and normally appear to be a dark blue or purple, spider veins are much smaller and can be red, purple, or blue in color. Both types of veins are caused by the twisting and turning of the vessels as the blood begins to flow backward and become trapped within the small crevices that have been created. The more the blood continues to build, the larger the veins become.
Laser technology has proven to have many benefits when used to treat varicose veins and the smaller, spider veins. Laser therapy can be used to seal the vein, allowing it to decay naturally. Laser procedures for varicose veins are non-invasive and have very few side effects other than mild irritation at the site of the treatment. The risk of infection is minimal and the patient can return to their normal, day to day routine as soon as they leave the doctor's office. The results of the treatment are long lasting and will be visible within a few weeks of the procedure. Laser technology is safer and more effective than the stripping techniques that were used in the past.
