Prominent veins in the hand… are they a sign of danger or normal?

Many people notice prominent veins in their hands, especially as they age or in thin, athletic individuals. Posts circulating on social media claim that visible veins can be a sign of a serious illness, but the truth is that it’s not always a cause for concern.

In most cases, visible veins are perfectly normal and appear due to a lack of subcutaneous fat or exercise that increases blood flow. High temperatures and aging can also make veins more noticeable.
