This is a condition where blood pools in your legs instead of flowing upward due to weakened blood vessel valves, causing the blood vessels to swell. The main causes 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 go down to your legs due to gravity, which puts excessive pressure on the blood vessels.
Age: As you age, the elasticity of your blood vessels decreases and the valves inside weaken. This prevents blood from returning to the heart and leads to varicose veins.
Hormonal changes and pregnancy: This disease is more common in women. This may be due to the increased blood volume in the body during pregnancy and the growing uterus putting pressure on the pelvic blood vessels. It is also caused by hormonal changes during menopause.
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 pump blood up the leg muscles and varicose veins develop.
Heredity: If someone in your family has varicose veins, it is more likely to pass them on to the next generation. This is because the walls of your blood vessels are genetically weakened.
