Chronic Venous Insufficiency and Obesity
Chronic venous insufficiency is a condition where leg veins struggle to return blood to the heart — and excess weight significantly worsens it.
Plain English
Patient-Friendly Explanation
Chronic venous insufficiency (CVI) happens when the one-way valves inside the leg veins become weak, so blood pools in the lower legs instead of flowing back to the heart. This causes swelling, heavy or aching legs, varicose veins and skin changes. Carrying excess weight increases the pressure inside the abdominal and leg veins, making CVI more likely and more severe. Weight loss, compression stockings and leg elevation all help.

Clinical Definition
Chronic venous insufficiency results from venous valvular incompetence and/or obstruction, causing venous hypertension, oedema, lipodermatosclerosis, skin hyperpigmentation and, in advanced stages, venous ulceration. Obesity is an independent risk factor: increased intra-abdominal pressure impairs venous return, and the CEAP classification is used for staging. Central obesity is particularly associated with higher venous pressure. Management combines compression therapy, leg elevation, exercise and weight reduction; endovenous ablation or surgery is considered where appropriate.
Key Insight
Why It Matters
Unexplained leg swelling in a heavier patient is often venous — not just 'carrying extra weight'. Weight loss is one of the most effective long-term treatments, and it is a core part of Dr Joseph Wang's care plans.
