What are varicose veins?
Varicose veins commonly appear later in adulthood, and mainly among people who have led a physically strenuous life. This condition often affects the superficial veins in the legs and ankles which become enlarged and maybe painful. They are usually not serious, but can lead to other health problems.
How does it happen?
The veins in the human body have one-way valves located at equal distances along its length that keep blood flowing from the legs to the heart and prevent backflow. However, under increased venous pressure, the valves malfunction and blood can flow back, impairing circulation. If the venous pressure continues to exist in the region, probably due to repeated activity owing to the nature of a person’s job or daily routine, the veins in the area begin to stretch and become swollen.
Habits and conditions that might lead to varicose veins include prolonged sitting, prolonged standing, sitting with legs crossed, excess weight, pregnancy, chronic constipation, heavy lifting, congenital diseases causing vein malformation, liver dysfunction and others.
