Is there a genetic component to varicose veins?

My mother had varicose vein surgery some time ago.

When I look at my legs, the veins haven't protruded yet, but they are quite visible.

Should I do something in advance to prevent deep vein thrombosis?

I think I need to look into the prevention law and make an effortㅜㅜ

How can I prevent varicose veins from developing?

Sometimes my hands and feet go numb, so I get really scaredㅠ
