ASK THE EXPERT - Why are my legs so veiny?

Dr Omar Abu-Bakr on the difference between normal veins and those needing medical attention

Veins are a type of blood vessel that form a vital V component of the circulatory system. They play a crucial role in the circulation of blood, ensuring the efficient return of deoxy genated blood to the heart and facilitating the continuous functioning of the body's organs and tissues. Cyclists often have more prominent leg veins, but how can you tell the difference between a healthy vein and one that may require treatment? Varicose veins are enlarged and swollen veins that occur in the legs and feet, affecting 20% of the UK population.

Varicose veins form when the valves within the veins do not function properly. These valves are responsible for preventing the backward flow of blood, aiding in the upward movement of blood towards the heart. When the valves become weak or damaged, they are unable to effectively regulate blood flow, causing blood to pool in the veins. Key symptoms include swelling, pain, discolouration of the skin, itching, and redness - though some people don't experience symptoms.

If left untreated, varicose veins can lead to serious health implications, such as deep vein thrombosis (DVT). It's therefore important to be aware of your vein health and seek treatment if you suspect or know you have varicose veins.
