From our 30s onwards, our body composition starts to change - we begin to lose muscle mass, muscle strength and endurance.

High blood pressure, high cholesterol or diabetes, can affect the blood vessels and restrict the normal flow of blood causing poor circulation.

Sitting or standing for long periods can significantly slow down blood flow, resulting in a lack of oxygen rich blood being resupplied to the legs and feet and the old, deoxygenated blood building up in the leg veins. The increased fluid in the lower leg is what causes the discomfort and over time can damage the leg veins.
