Venous Stasis Eczema: Symptoms, Causes, and UK Management Guide

Venous stasis eczema, also frequently referred to as varicose eczema or gravitational eczema, is a common long-term skin condition that affects the lower legs. It is most prevalent in older adults and those who suffer from chronic venous insufficiency (CVI).

Unlike atopic eczema, which is often linked to allergies or genetics, stasis eczema is a direct result of circulatory issues. When the valves in the leg veins weaken, blood struggles to flow back up to the heart against gravity. This causes blood to 'pool' in the lower legs, increasing pressure in the veins. This pressure causes fluid to leak into the surrounding tissues, triggering an inflammatory response in the skin that leads to the classic symptoms of eczema.

The symptoms of venous stasis eczema typically develop gradually and are usually confined to the area between the mid-calf and the ankle. In the United Kingdom, patients often describe the following signs to their GP:

• Skin Discolouration: The skin may look red or brown. The brown pigment (haemosiderin) occurs when red blood cells leak out of the veins and break down in the skin.
• Itching and Irritation: The affected area often feels intensely itchy, leading to scratching which can damage the skin further.
• Scaling and Crustiness: The skin may become very dry, scaly, or develop crusty patches that might leak fluid (weeping eczema).
• Swollen Legs: Many patients notice that their legs are more swollen at the end of the day (oedema), which usually improves after a night’s sleep with legs elevated.
• Atrophie Blanche: Small, smooth, white scars may appear amongst the discoloured skin.

According to NHS guidance, venous stasis eczema is caused by increased pressure in the veins. Several factors can increase your risk of developing this circulatory pressure:

• Age: It is more common as we get older and our veins become less elastic.
• Varicose Veins: These are a primary indicator that the valves in the veins are not working effectively.
• Deep Vein Thrombosis (DVT): A previous blood clot in the leg can damage the valves.
• Mobility Issues: Being unable to walk or move regularly reduces the 'calf muscle pump' action that helps push blood upwards.
• Weight: Being overweight increases the pressure on the leg veins.
• Pregnancy: Hormonal changes and increased blood volume can put extra strain on the circulatory system.

The management of venous stasis eczema follows NICE (National Institute for Health and Care Excellence) pathways, focusing on both the skin symptoms and the underlying circulatory problem.

Skin Care and Emollients

Keeping the skin hydrated is essential. Patients are advised to use medical-grade emollients (moisturisers) several times a day. These should be applied gently in the direction of hair growth to avoid blocking follicles. Soap substitutes should be used instead of traditional bubbly soaps, which can further dry out the skin.

Topical Steroids

During a 'flare-up' where the skin is particularly red and inflamed, a GP may prescribe a topical steroid cream or ointment. These are used sparingly for a short period to reduce inflammation. In the UK, common options include hydrocortisone or stronger preparations like betamethasone, depending on the severity.

Compression Therapy

This is the 'gold standard' for treating the underlying cause. Once a GP or nurse has performed an ABPI (Ankle-Brachial Pressure Index) test to ensure the arterial circulation is healthy, they may recommend compression stockings. These apply graduated pressure to the leg to help the veins move blood back towards the heart.

Managing a chronic condition like venous stasis eczema often requires ongoing support and prescription repeats. If you are struggling to manage your skin symptoms or if your current treatment is no longer effective, you can speak to a GP online for a clinical review.

An online doctor can examine clear photographs of your leg, discuss your medical history, and provide a diagnosis. They can offer advice on the best emollients for your skin type and, where appropriate, issue a private prescription for steroid creams or medicated bandages. Furthermore, if you are working and your condition is making it difficult to stand for long periods, an online doctor can provide sick notes or advice on workplace adjustments. Seeking help early is key to preventing the progression of the disease into venous ulcers.

If venous stasis eczema is not managed correctly, it can lead to more serious health issues. The most significant concern is the development of a venous leg ulcer, which is a long-lasting sore that takes more than two weeks to heal. Additionally, the damaged skin barrier makes the leg more susceptible to cellulitis, a bacterial infection of the deeper layers of the skin.

Simple lifestyle changes can help: avoid standing for long periods, try to walk for 30 minutes a day to improve circulation, and elevate your legs above the level of your heart whenever you are sitting or lying down.
