Part 4/5:
Chronic venous insufficiency (CVI) is a condition where the veins in the legs do not effectively send blood back to the heart. When veins are weakened or damaged, blood can flow backwards, pooling in the legs and causing symptoms such as swelling, varicose veins, and skin changes. While common among older adults, CVI can affect individuals of different ages and is typically manageable with lifestyle modifications and medical treatments.
