Before you sound the alarm, it’s good to know that in the majority of cases, these newly visible veins are harmless. Here are some very simple explanations:
Fat loss: Less fat under the skin = more visible veins. Nothing abnormal, especially if you have changed your diet or resumed physical activity.
Sport and bodybuilding: Blood flow increases during exercise, muscles swell… and veins pop out, pushed towards the surface. This is even a desired effect among athletes.
Heat: In high temperatures, veins dilate to better regulate body heat. This naturally makes them more visible.
Age: Over time, the skin thins and loses elasticity, allowing what is underneath to show through more easily, including the veins.
Hormonal changes: Pregnancy, menopause, hormone therapy… hormonal changes can temporarily alter blood circulation.
In short, in many cases, it’s simply the body adapting.
But then, when should we really be worried?
