What are varicose veins?
One-way valves normally allow blood to travel in the veins from the foot back to the heart without flowing back down in the other direction (‘refluxing’). If the valves stop working properly (become leaky or ‘incompetent’) blood pools in the surface leg veins which then swell up over time and become ‘varicose’.
