This is a condition where blood pools in your legs instead of flowing to your heart due to weakened blood vessel valves, causing your arteries to swell. The main factors that lead to this are:
Prolonged standing: This problem is more common in people who have to stand for hours on end (for example, teachers, security guards, nurses). When you stand, the blood tries to flow down to your legs due to gravity, which puts excessive pressure on your blood vessels.
Age: As you age, the elasticity of your blood vessels decreases and the valves inside weaken. This affects the process of pumping blood upward and leads to varicose veins.
Hormonal changes and pregnancy: This disease is more common in women. This may be due to the increase in blood volume in the body during pregnancy and the growing uterus putting pressure on the blood vessels in your legs. In addition, hormonal changes during menopause can also cause the walls of blood vessels to become loose.
Obesity and lack of exercise: When you gain weight, the blood vessels in your legs experience more pressure than they can handle. Even those who do not exercise, such as walking, cannot push blood up the leg muscles and varicose veins develop.
Heredity: If your parents or someone else in your family has varicose veins, it is more likely to happen to the next generation. This is because the walls of your blood vessels are genetically weakened.
