Varicose Eczema (Venous Eczema): Symptoms, Causes and UK Management

Varicose eczema, also known as stasis or venous eczema, is a chronic condition that causes the skin on the lower legs to become itchy, red, dry, and flaky. Unlike atopic eczema, which is often linked to allergies or genetics, varicose eczema is a direct result of venous insufficiency—a circulatory issue where the valves in the leg veins fail to pump blood efficiently back to the heart.

According to NHS data, this condition is particularly common in older adults and those who spend long periods standing. When blood pools in the lower legs, the increased pressure (venous hypertension) causes fluid to leak into the surrounding tissues. This triggers an inflammatory response in the skin, leading to the characteristic dermatitis seen by GPs across the UK.

The symptoms of varicose eczema typically develop gradually and are usually concentrated around the ankles or shins. Patients may notice:

• Skin Changes: Redness, itchiness, and dryness. On darker skin tones, the affected areas may appear dark brown, purple, or grey.
• Texture: The skin may become crusty, scaly, or develop small blisters that leak fluid.
• Pigmentation: Long-term pressure can cause brown patches of skin, known as haemosiderin staining.
• Lipodermatosclerosis: In advanced cases, the skin may become hard, tight, and scarred, often described as an 'inverted champagne bottle' shape of the leg.
• Pain: A heavy, aching feeling in the legs that worsens after standing for long periods.

Varicose eczema is caused by increased pressure in the veins. Under normal conditions, tiny valves in the veins ensure blood flows one way—upwards. If these valves weaken or fail, blood flows backwards and collects in the legs. Factors that increase your risk include:

• A history of varicose veins.
• Previous Deep Vein Thrombosis (DVT), which can damage leg valves.
• Chronic swelling (oedema) caused by heart or kidney issues.
• Being overweight or having multiple pregnancies, both of which increase abdominal and leg pressure.
• A sedentary lifestyle or a job that requires prolonged standing.

The National Institute for Health and Care Excellence (NICE) provides clear pathways for managing varicose eczema in the UK. The primary goal is to address the underlying circulation issues while treating the skin inflammation. Standard management includes:

1. Emollients and Topical Steroids

Keeping the skin hydrated is essential. Thick, fragrance-free emollients should be applied frequently to prevent cracking. If the eczema flares up, a GP may prescribe a mild to moderate topical corticosteroid to reduce inflammation and itching.

2. Compression Therapy

If there is no evidence of arterial disease, compression stockings (available via prescription or over-the-counter) are the gold standard. They apply pressure to the legs to encourage blood flow upwards, reducing the venous hypertension that causes the eczema.

3. Lifestyle Adjustments

UK health experts recommend elevating the legs above the heart when resting, staying active to improve the 'calf muscle pump,' and avoiding long periods of standing or sitting still.

Managing a long-term condition like varicose eczema requires consistent medical oversight. You may choose to speak to a GP online if you notice new skin changes, persistent itching that disrupts sleep, or if your current treatments are no longer effective.

An online doctor can review your symptoms via a video consultation, offer advice on the correct application of emollients, and issue private prescriptions for medicated creams if appropriate. Furthermore, an online GP can help determine if you need a referral for a Vascular Assessment, which is recommended by NICE if you have symptomatic varicose veins alongside your eczema.

The most significant complication of untreated varicose eczema is the development of a venous leg ulcer. Because the skin in the affected area is fragile and the circulation is poor, even a minor scratch or knock can lead to a chronic wound that is difficult to heal. By managing the eczema effectively with compression and skin care, you significantly reduce the risk of these painful and debilitating ulcers.
