Have you noticed blue or green veins becoming more visible on your hands, arms or legs? While this can sometimes be completely normal, changes in the appearance of veins may also be linked to certain health conditions.
1. Ageing: As people grow older, their skin gradually becomes thinner and loses some of its elasticity. This can make veins underneath the skin easier to see.
2. Low body fat: People with less fat beneath their skin may naturally have more visible veins, particularly around their hands and arms.
3. Exercise: Physical activity increases blood flow to working muscles. This can temporarily make veins appear more prominent.
4. Hot weather: Heat causes blood vessels near the skin to widen, which may make superficial veins easier to notice.
5. Varicose veins: These are enlarged, twisted veins that commonly appear in the legs. They may cause aching, heaviness, itching or swelling.
6. Pregnancy: Pregnancy increases blood volume and changes circulation. Hormonal changes and pressure from the growing womb can also contribute to more noticeable veins.
Visible veins do not automatically mean that something is wrong. However, sudden changes should not be ignored.
Seek medical advice if you notice new swelling, persistent pain, skin changes or a vein that becomes hard and tender. Sudden swelling in one leg, particularly with pain, needs urgent assessment.
Understanding what is normal for your body can help you recognise when a change deserves attention.
