Varicose veins

These veins are more visible as they are larger and more ‘knotty’ than surrounding veins and are usually blue or dark purple.

Veins

These veins are more visible as they are larger and more ‘knotty’ than surrounding veins and are usually blue or dark purple.

They develop when the small valves inside the veins stop working correctly and blood is prevented from flowing backwards by a series of tiny valves that open and close to let blood through.

If the valves weaken or are damaged, the blood can flow backwards and collect in the vein, eventually causing it to be swollen and enlarged (varicose).

Varicose veins can appear for a number of reasons, including:

  • Obesity
  • Ageing
  • Hormonal imbalances
  • Long periods of standing or sitting
  • Lack of physical activity in general
  • Pregnancy
  • Being female

Varicose veins may lead to issues such as blood clots, causing swelling and pain.
They may also cause skin sores that are difficult to heal.

There are several types of varicose veins, such as:

  • Trunk – near to the surface, thick and knobbly
  • Reticular – red and sometimes grouped close together in a network
  • Telangiectasia – also known as thread/spider veins. These are small clusters of blue or red veins that sometimes appear on your face or legs.
