Summary

This registry follows 10,000 people with early varicose veins to see how chronic venous disease develops and worsens over time. Researchers will track signs like spider veins, swelling, skin changes, and blood clots using yearly checkups and ultrasound scans. The goal is to better understand risk factors and the natural course of the disease, which could improve prevention and treatment strategies.

What could go wrong: This is an observational study, not a treatment trial. It will not test any new therapy, and results may take years to produce actionable insights.
