What causes green veins?

Green veins are usually caused by prominent subdermal veins. These are veins that lie just below the surface of the skin and are often visible through the skin. They are usually more noticeable in people with fair skin or who are thin.

Some other causes of green veins include:

- Certain medical conditions, such as liver disease, heart failure, or kidney failure.

- Medications, such as steroids or birth control pills.

- Pregnancy.

- Aging.

- Genetics.

If you are concerned about the appearance of green veins, you should see a doctor to rule out any underlying medical conditions.
