Quick Answer
Chronic venous insufficiency occurs when the veins in your legs struggle to pump blood back up to your heart. Instead, blood pools in the lower legs, which can lead to swelling, aching, heavy-feeling legs, and visible varicose veins. Over time, this pooling may cause the skin to thicken, turn a brownish colour, or even develop open sores known as ulcers. It is a manageable condition, often improving with simple lifestyle changes, compression garments, or medical procedures. Always consult a healthcare professional for a proper evaluation.

Frequently Asked Questions
How do I know if I have chronic venous insufficiency?
Early signs usually include a heavy, aching feeling in the legs, especially after standing for long periods. You might notice swelling around your ankles, visible varicose veins, or itchy legs. As the condition progresses, the skin on your lower legs may become thick, leathery, and develop a brown or reddish discolouration, sometimes called stasis dermatitis.
Why did my leg veins stop working properly?
Veins have one-way valves that keep blood moving upward toward the heart. Chronic venous insufficiency happens when these valves become weak or damaged, allowing blood to flow backward and pool in the legs. Common risk factors include a history of deep vein thrombosis, obesity, pregnancy, a strong family history of vein issues, advancing age, and occupations requiring prolonged standing.
How do doctors treat this condition?
Treatment focuses on improving blood flow and reducing leg swelling. The most common first step is wearing prescription compression stockings and elevating your legs when resting. Exercise, particularly walking, helps calf muscles pump blood upward. If these measures are not enough, doctors may recommend minimally invasive vein procedures, such as sclerotherapy or ablation, to close off the damaged veins.
Can chronic venous insufficiency be completely cured?
While damaged vein valves cannot be repaired, the condition is highly manageable. With consistent treatment like wearing compression garments, staying active, and managing your weight, you can effectively control symptoms and prevent complications. Minimally invasive procedures can resolve specific problematic veins, but because it is a chronic condition, maintaining healthy leg habits is essential for long-term relief.
When should I see a doctor about my leg swelling?
You should consult a healthcare provider if you experience persistent leg swelling, aching, or heaviness that does not improve with rest. It is especially important to seek medical help if you notice skin changes, such as thickening or brownish discolouration, or if you develop an open sore or ulcer on your leg. Prompt treatment helps prevent irreversible skin damage.
Is this the same thing as poor circulation in the arteries?
No, they are different conditions. Chronic venous insufficiency involves damaged veins struggling to return blood to the heart, causing pooling and swelling. Peripheral arterial disease involves narrowed arteries struggling to deliver oxygen-rich blood down to the legs, often causing pain while walking. Both require a doctor's evaluation, as the treatments, particularly the use of compression therapy, differ significantly.
Is it true that only older adults get venous insufficiency?
This is a common myth. While the risk does increase as you get older, chronic venous insufficiency can affect younger people as well. Pregnancy, obesity, a previous blood clot, or having a job that requires standing for hours every day can trigger vein problems at a younger age. Taking preventative steps like regular exercise and avoiding prolonged standing helps everyone.
How can ScanSkinAI help with chronic venous insufficiency?
ScanSkinAI can help you monitor visible skin changes on your legs, such as brownish discolouration, varicose veins, or early signs of ulcers. However, our AI is only a screening aid and cannot diagnose chronic venous insufficiency or any other medical condition. You must consult a qualified healthcare professional for a medical evaluation, proper diagnosis, and a suitable treatment plan.
