Spider veins are small, red, purple, and blue vessels that appear to twist and turn. They are easily visible through the skin, typically on the legs and face.
Causes of Spider Veins
A number of factors predispose a person to this condition. These include:
- Occupations that involve standing frequently
- Hormonal influences of pregnancy, puberty, and menopause
- Use of birth control pills
- Postmenopausal hormonal replacement
- History of blood clots
- Conditions that cause increased pressure in the abdomen, such as tumors, constipation, and externally worn garments.
Other reported causes include trauma or injury to the skin, previous vein surgery, and exposure to ultraviolet rays.
