When the layer of fat under the skin decreases, the veins naturally become more visible.
This is often the case in very thin people or those who have recently lost weight.
-
Physical activity
During exercise, blood flow increases in order to supply the muscles.
The veins can then dilate and appear more prominent. In people who exercise regularly, this effect can become more lasting.
-
The heat
In hot weather, blood vessels dilate to help the body regulate its temperature.
As a result, veins may become more visible, especially in the hands and feet.
-
Natural aging
With age, the skin becomes thinner and loses some of its elasticity.
This natural evolution makes the veins more visible under the skin.
-
Hormonal changes
Certain periods in life, such as pregnancy or menopause, can alter blood circulation and make veins more visible.
Hormonal treatments can also produce this effect.
When should we be more attentive?
In most cases, visible veins pose no danger.
However, certain signs may warrant medical advice.
-
Sudden and unusual appearance
If very prominent veins appear without any obvious reason (for example, without weight loss or change in physical activity), it may be helpful to consult a doctor.
-
Pain or swelling
Visible veins accompanied by pain, heat, or swelling may signal a circulation problem .
