Educational guidance from Avis Vascular Centre highlights that varicose veins are not just about visible veins—they cause progressive and serious skin changes if left untreated. Recognising these warning signs early can prevent long-term complications like non-healing ulcers.
Why Skin Changes Occur in Varicose Veins
When varicose veins develop, blood does not flow back efficiently to the heart. Instead, it stagnates in the lower legs, creating increased pressure inside the veins.
This stagnant blood leads to:
- Breakdown of red blood cells
- Release of iron particles (hemosiderin)
- Deposition of these particles into the surrounding skin
Over time, this causes visible and progressive skin damage.
Early Skin Changes: Brown to Black Discolouration
One of the first visible signs is skin discolouration, usually around the ankle and lower leg.
- Skin turns brown initially
- Gradually darkens to deep brown or black
- Often mistaken for pigmentation or allergy
This colour change is a clear indicator of chronic venous disease, not a cosmetic issue.
Advanced Changes: Thin, Shiny, Fragile Skin
If varicose veins remain untreated:
- Skin becomes thin and glossy
- Loses its normal strength and elasticity
- Becomes extremely fragile
At this stage, the skin is poorly nourished due to impaired circulation, making healing very difficult.
Why Minor Injuries Become Major Problems
In advanced venous disease:
- Even a small scratch or minor injury can break the skin
- Wounds fail to heal normally
- This leads to chronic venous ulcers
These ulcers:
- Are painful and slow to heal
- Recur frequently
- Significantly affect quality of life
The root cause is not the wound itself, but poor blood circulation underneath.
Why These Skin Changes Are a Serious Warning
Skin discoloration, thinning, and ulcers indicate that varicose veins have progressed beyond early stages. At this point:
- Simple home remedies are not enough
- Delaying treatment increases the risk of infection
- Recovery becomes longer and more complex
The Importance of Early Recognition and Action
The key message from Avis Vascular Centre is clear:
- Skin changes are warning signs, not cosmetic problems
- Early medical evaluation can prevent ulcers
- Treating the vein problem early protects the skin
