It can also happen during periods of illness or unintentional weight loss.
When veins become more visible because there is less tissue covering them, the veins themselves haven’t necessarily changed dramatically.
They may simply be easier to see.
This is why athletes and people with relatively low body-fat levels can sometimes have highly visible veins in their hands, arms, shoulders, or legs.
Again, visibility by itself doesn’t automatically indicate a health problem.
The circumstances surrounding the change matter.
## Aging Can Make Hand Veins More Prominent
As we get older, the appearance of our hands naturally changes.
Skin gradually becomes thinner and loses some of its elasticity.
The layer of fat beneath the skin can also decrease.
Together, these changes can make veins, tendons, and other structures more noticeable.
A person who had relatively smooth-looking hands when they were younger may eventually notice prominent veins and tendons.
This can happen gradually and is usually a normal part of aging.
The hands can also develop other visible changes over time, including wrinkles, spots, and changes in skin texture.
Therefore, seeing more prominent veins as you age is not necessarily a warning sign.
However, a **sudden and dramatic change** is different from a gradual change that has occurred over many years.
