Venous disease is common to both men and women (20% of men and 40% of women get Venous disease). Why do women suffer more than men with vein problems? For women pregnancy and hormonal fluctuations (namely progesterone) are the biggest culprits. Swelling of the legs, a/k/a edema is more prevalent in men, with superficial thrombophlebitis more likely to affect women.
If you’re lucky enough to have remained unscathed by any type of venous disease thus far in your life, just wait a little longer. People in their 70s are twice as likely to have venous disease as those in their 40s. A lifetime of activities like heavy lifting, coughing, even straining to have a bowel movement, all contribute to pressure on leg veins. A sedentary life style, obesity and a diet high in fat are all contributing factors to venous issues, because a fatty diet and lack of exercise decrease the efficiency of blood flow through large leg veins, thus increasing the likelihood of developing varicose veins or spider veins.
