Key points

  • Chronic Venous Insufficiency (CVI) occurs when leg veins struggle to return blood to the heart.
  • Common symptoms include heavy, aching legs, swelling (oedema), and skin changes such as varicose eczema.
  • Management focuses on improving circulation through lifestyle changes and compression therapy.
  • If left untreated, CVI can lead to painful venous leg ulcers and skin infection.
  • A UK online doctor can assess your symptoms and provide management plans or referrals.

What is Chronic Venous Insufficiency?

Chronic Venous Insufficiency (CVI) is a long-term medical condition where the veins in the legs are unable to effectively pump blood back to the heart. In a healthy circulatory system, tiny valves inside your veins ensure that blood flows in one direction—upwards. When these valves become damaged or weakened, blood can flow backwards and pool in the lower legs, a process known as venous reflux.

This increased pressure in the leg veins leads to a variety of symptoms, ranging from mild discomfort and swelling to more severe complications like skin thickening and ulcers. In the UK, CVI is a common condition, often associated with varicose veins, but it can also occur in patients without visible bulging veins. According to NICE (National Institute for Health and Care Excellence) guidelines, early intervention is key to preventing the progression of venous disease.

Recognising the Symptoms of CVI

The symptoms of Chronic Venous Insufficiency often develop gradually and may worsen throughout the day, particularly if you spend a lot of time standing or sitting still. Patients in the UK commonly report the following:

  • Oedema: Swelling in the ankles and lower legs, which typically improves after a night's sleep.
  • Heavy Legs: A persistent feeling of heaviness, aching, or throbbing in the calves.
  • Skin Changes: The skin may become discoloured (brownish or reddish), itchy, or dry—a condition known as varicose eczema or stasis dermatitis.
  • Haemosiderin Staining: Dark patches on the skin caused by iron deposits from blood leaking out of the capillaries.
  • Lipodermatosclerosis: The skin around the ankles becomes hard, tight, and scarred.

If you notice these changes, it is important to seek medical advice to prevent the development of venous leg ulcers, which are difficult to heal and require specialist nursing care.

Causes and Risk Factors

Several factors can contribute to the weakening of vein valves. Understanding these risks can help in managing the condition effectively. Primary causes include:

  • Deep Vein Thrombosis (DVT): A previous blood clot in the leg can damage valves permanently.
  • Age and Genetics: The risk increases as we get older, and a family history of varicose veins is a significant predictor.
  • Lifestyle: Obesity and lack of physical activity put extra strain on the venous system.
  • Occupation: Jobs that require long periods of standing (such as retail or nursing) or prolonged sitting can exacerbate venous pooling.
  • Pregnancy: Hormonal changes and increased blood volume during pregnancy can temporarily or permanently damage leg veins.

Managing CVI: The UK Standard of Care

Management of Chronic Venous Insufficiency in the UK typically follows a tiered approach focused on conservative measures first. The goal is to reduce venous pressure and improve blood flow.

Compression Therapy

Compression stockings are the cornerstone of CVI treatment. These apply graduated pressure to the legs, helping the vein valves function and reducing swelling. It is essential to have your legs measured by a healthcare professional and to have a Doppler ultrasound test (to check arterial circulation) before starting high-grade compression.

Lifestyle Adjustments

Practical steps can significantly improve your quality of life:

  • Leg Elevation: Raise your feet above the level of your heart for 15-20 minutes several times a day.
  • Exercise: Regular walking encourages the 'calf muscle pump', which helps push blood upwards.
  • Weight Management: Reducing excess weight lowers the pressure on your lower limb veins.
  • Skin Care: Using unperfumed emollients can help manage dry, itchy skin and prevent the cracks that lead to infection.

Speak to a GP Online for CVI Management

Many patients find it difficult to manage chronic leg discomfort alongside a busy schedule. You can speak to a GP online to discuss your symptoms and receive evidence-based advice tailored to the UK healthcare landscape. An online GP consultation can help you determine the severity of your CVI and whether you require a referral to a vascular specialist for treatments like endothermal ablation or sclerotherapy.

During a digital appointment, your GP can review your medical history, discuss the suitability of compression garments, and provide advice on managing varicose eczema. If your condition prevents you from working or requires specific workplace adjustments, an online GP can also assist with medical evidence or sick notes where appropriate.

Potential Complications

Ignoring the early signs of CVI can lead to serious long-term complications. The most concerning is the venous leg ulcer—a chronic sore that takes more than two weeks to heal. These ulcers often form on the inside of the ankle and can become infected. Other risks include cellulitis (a deep skin infection) and superficial thrombophlebitis (inflammation of a vein near the surface of the skin). Following NHS guidance on leg health is vital to avoid these outcomes.

Red flags — when to seek urgent help

Call 999 or go to A&E if you experience any of the following:

  • Sudden, painful swelling in one leg only (possible DVT).
  • Skin that is hot, very red, and painful to the touch (possible cellulitis).
  • A leg ulcer that is bleeding excessively or showing signs of pus.
  • Sudden shortness of breath or chest pain (possible pulmonary embolism).
