In warm weather or at elevated body temperature, blood vessels dilate. This is a natural mechanism for cooling the body.
4️⃣ Genetic predisposition
Some people simply have more superficial veins. This is not a disease, but an individual feature.
⚠️ When can visible veins be a signal of a problem?
In some cases, clearly defined or protruding veins can be associated with health conditions:
Chronic venous insufficiency
If the veins are painful, swollen or accompanied by heaviness in the extremities, this can be a sign of a problem with the venous return of blood.
Varicose veins
They usually appear on the legs, but can also affect other areas. The veins appear twisted, swollen and sometimes painful.
Dehydration
Insufficient water intake can temporarily make the veins more visible.
Hormonal changes
Pregnancy, menopause or hormone therapies can affect the condition of the veins.
