Spider veins are typically caused by abnormal blood flow and weakening of the blood vessel wall. Any condition or activity that places pressure on the veins (like weight gain, prolonged sitting or standing) can contribute to their development.
Spider veins increase with age and thus are quite common in the elderly. There is also a genetic basis, since spider veins do tend to run in families. In pregnancy, spider veins are quite common and have been associated with an increase in the female sex hormone, estrogen. Estrogen is known to weaken the walls of the veins and may contribute to the development of spider veins.
Once developed, spider veins generally get worse and do not resolve on their own. Weight gain, lack of exercise and a sedentary life style is associated with progression of spider veins.
Who Is A Candidate?
Appropriate candidates for laser vein removal are those individuals who have spider veins, who are non-smoking individuals, are physically healthy, and has no disease of the blood vessels or problems with bleeding. Since in laser vein removal lasers directly contact the skin, those with a tendency to form keloid scars are not ideal candidates. Skin tone can also be affected by laser vein removal treatment, so it is best to talk to your doctor about the type of laser appropriate for you.
What Preparations Are Needed?
Avoid sun exposure, aspirin, alcohol and not smoke for at least a week prior to the procedure. On the day of the treatment, avoid all creams, lotions and moisturizers on the area that is going to be treated.
Is The Treatment Covered By Insurance?
No. Spider veins do not cause symptoms and are of a cosmetic concern only.
