Are there any prevention methods for varicose veins?

I thought varicose veins were a disease that doesn't happen very often.

It seems that's not the case either. It looks like many people are getting it.

The photos of severe varicose veins are really gross. Is there a way to prevent getting them?

Are you talking about exercise or diet therapy??

Please let me know if you have any secret preventive methods.

I will try to imitate.
