In this article, we review what a varicose vein is, why it develops, and which signs may indicate that a medical evaluation is advisable.
What Is a Varicose Vein?
A varicose vein is a permanently dilated vein in which blood circulation becomes less efficient. Normally, veins contain valves that prevent blood from flowing backward. When these valves become less effective, blood can accumulate, leading to progressive vein dilation and weakening of the vein walls.
Why Do Varicose Veins Develop?
While the exact causes are not always clearly defined, several factors are known to increase the risk:
- Heredity
- Pregnancy and hormonal changes
- Prolonged periods of standing or sitting
- Aging of tissues
- Excess weight
These factors may act alone or in combination and contribute to the progression of venous disease over time.
What Does a Varicose Vein Look Like?
The appearance of varicose veins can vary significantly depending on their type and location.
- Spider veins: Small, thin red or bluish veins visible near the skin’s surface. They are usually minimally or not painful.
- Superficial varicose veins: Larger veins, sometimes raised, bluish or purplish, and easily visible.
- Deep varicose veins: Not externally visible but may be associated with more significant symptoms.
The absence of visible veins does not necessarily mean the absence of a venous condition.
Symptoms to Watch For
Varicose veins may be associated with various symptoms, which vary in intensity:
- Sensation of heaviness in the legs
- Swelling of the feet or ankles
- Cramps, especially in the evening or at night
- Tingling or itching
- Feeling of restlessness in the legs
These symptoms may worsen over time if left untreated.
Why Is It Important to Consult?
Even when varicose veins appear harmless, a medical evaluation helps determine their nature and extent. Beyond aesthetic concerns, varicose veins may progress and, in some cases, lead to complications such as inflammation, superficial phlebitis, ulcers, or bleeding.
Medical follow-up allows appropriate management and treatment planning.
Can Varicose Veins Be Prevented?
Certain habits may help limit their development or progression:
- Elevate the legs regularly
- Change positions frequently throughout the day
- Avoid intense heat exposure (very hot baths, saunas, tanning)
- Wear non-restrictive clothing, especially around the ankles
These measures do not replace a medical evaluation but may contribute to venous comfort.
A medical evaluation allows for an accurate diagnosis of your varicose veins.
