This is a condition in which the blood vessels in your legs become swollen (blue or dark red in color). It occurs when the valves in the veins that carry blood back to the heart weaken. The main causes are:
Prolonged standing: People who stand for long periods of time, such as teachers, security guards, traffic police, and nurses, experience excessive pressure on the veins in their legs. This causes blood to pool and cause the veins to swell.
Age and gender: As we age, the elasticity of the veins decreases and the valves become weaker. This condition is more common in women than men. This is due to hormonal changes associated with menopause and pregnancy.
Obesity and lack of exercise: As we gain weight, the pressure on the veins in our legs increases. Slow blood circulation in people who do not exercise regularly increases the risk of varicose veins.
Pregnancy: During pregnancy, the amount of blood in the body increases and the expanding uterus puts pressure on the veins in the legs. This can cause the veins to swell. This usually subsides after delivery in most people.
Heredity: If someone in the family has varicose veins, the risk of developing them is higher. It is possible that the characteristics of the structure of the veins are passed down through inheritance.
