There are many reasons for varicose veins, both congenital and acquired. Congenital is a certain genetic tendency, not 100% inheritance, but there will be family gathering, parents have varicose veins, it is relatively easy to have children, or some brothers and sisters have varicose veins, which is more common. The day after tomorrow, it is very easy for some people to stand for a long time, such as teachers, shop assistants, barbers and chefs, including our surgeons and operating room nurses, to get varicose veins. The other is weight. If he is obese and very heavy, the blood vessels on his legs are heavily burdened and it is easy to cause varicose veins. Another fact is that when a woman is pregnant, the uterine compression increases, blocking the inferior vena cava, leading to an increase in leg pressure, so the proportion of women suffering from varicose veins is higher than that of men.
