Breaking News: Chronic Venous Insufficiency Linked to Genetics, Affects Critically important Portion of Global Population
São Paulo, Brazil – July 17, 2025 – Genetics stands as the primary determinant of chronic venous insufficiency, a widespread condition that manifests in various ways, including varicose veins. While other risk factors such as obesity, aging, pregnancies, and prolonged periods of sitting or standing contribute to its development, the underlying genetic predisposition is the most significant factor. Although a history of deep vein thrombosis can be a secondary cause, it is not the most common, with some studies indicating onyl a small increased risk of thrombosis in individuals with chronic venous insufficiency.Evergreen context: Understanding chronic Venous Insufficiency
Chronic venous insufficiency (CVI) is a highly prevalent medical condition affecting a substantial segment of the global population. According to data from the Brazilian Society of angiology and Vascular Surgery (SBACV), international studies suggest that up to 80% of individuals may experience milder forms of the condition. Intermediate stages of CVI are reported in 20% to 64% of people, with a progression to more severe stages occurring in approximately 1% to 5% of the population. National studies in Brazil mirror these figures for early and intermediate stages, but indicate a higher trend towards more severe cases, potentially affecting 15% to 20% of the population.
The diagnosis of CVI relies on a combination of medical evaluation and diagnostic tests. While the appearance of symptoms and physical signs can be indicative, Doppler ultrasound of the legs is crucial for confirming the diagnosis and ruling out deep vein thrombosis as the cause of swelling.
Currently, there is no definitive cure for chronic venous insufficiency.Though, effective treatments are available to manage symptoms and improve quality of life. Regular exercise is highly beneficial in alleviating symptoms. For individuals experiencing swelling, the use of elastic compression stockings can provide relief. Additionally, specific medications may be prescribed. In more advanced cases of venous insufficiency, surgical intervention to remove the affected vein might potentially be recommended.
