Chronic Venous Hypertension: Symptoms, Treatment & UK Online Doctor Guide

Chronic venous hypertension is a long-term condition where the blood pressure in the veins of your legs remains abnormally high. In a healthy circulatory system, valves in the veins ensure that blood flows upwards toward the heart. When these valves become weakened or damaged, blood can pool in the lower legs, a process known as venous reflux.

According to NHS data, this condition is relatively common, particularly in older adults and those with a history of deep vein thrombosis (DVT). The sustained high pressure forces fluid out of the veins and into the skin and surrounding tissues, leading to the chronic swelling (oedema) and skin inflammation characteristic of the condition. While it is often associated with varicose veins, it can occur even if no large veins are visible on the surface.

The symptoms of chronic venous hypertension often develop gradually and may worsen towards the end of the day or in hot weather. Many patients in the UK initially dismiss these signs as a normal part of ageing, but early identification is vital for effective management.

• Aching and heaviness: A persistent dull ache in the calves, especially after standing or sitting for long periods.
• Oedema: Swelling of the ankles and lower legs that typically improves after a night's sleep.
• Skin Changes: The skin may become discoloured (often a brownish or reddish tint), itchy, or hardened. This is sometimes referred to as varicose eczema or lipodermatosclerosis.
• Restless Legs: An uncomfortable urge to move the legs, particularly in the evening.
• Venous Ulcers: Small sores or breaks in the skin, usually near the ankle, that are slow to heal.

Several factors contribute to the development of venous hypertension. Understanding these can help in both prevention and management. The primary cause is venous valve incompetence, but other risk factors include:

• Age and Genetics: A family history of vein problems and the natural weakening of tissues with age.
• Obesity: Excess weight puts significant pressure on the veins of the lower limbs.
• Pregnancy: Hormonal changes and increased blood volume can strain the venous system.
• Sedentary Lifestyle: Lack of movement means the calf muscle pump, which helps push blood upwards, is not activated.
• Previous DVT: A past blood clot can permanently damage the delicate valves within the deep veins.

Treatment for chronic venous hypertension is largely focused on reducing the pressure within the veins and improving circulation. The National Institute for Health and Care Excellence (NICE) provides clear guidelines on the tiered approach to management.

Compression Therapy

Compression stockings are the cornerstone of treatment. They apply graduated pressure to the leg, helping the veins and leg muscles move blood more efficiently. It is important to have your legs measured correctly to ensure the stockings provide the right grade of compression without being restrictive.

Lifestyle Modifications

Simple changes can significantly alleviate symptoms. These include elevating your legs above the level of your heart for 30 minutes several times a day, maintaining a healthy weight to reduce venous load, and avoiding long periods of stationary standing or sitting. Regular walking is highly encouraged as it strengthens the calf muscles.

Skin Care

Moisturising the skin on the lower legs with emollients can prevent the cracking and itching associated with venous eczema, reducing the risk of infection.

If you are experiencing persistent leg swelling, skin discolouration, or discomfort, you should speak to a GP online or in person. Managing chronic conditions online is increasingly common in the UK, offering a convenient way to discuss long-term symptoms without leaving home.

An online doctor can review your clinical history, assess the severity of your symptoms via video or photos, and provide an initial management plan. They can advise on the appropriate type of compression garments and, if necessary, provide a referral to a vascular specialist for further investigations such as a Duplex ultrasound scan. Early consultation is particularly important if you notice any new skin breaks or signs of infection, such as increased redness or heat in the leg.

Ignoring the early signs of chronic venous hypertension can lead to debilitating complications. One of the most common is the development of a venous leg ulcer, which is a chronic wound that can take months to heal and is prone to infection. Another risk is cellulitis, a serious bacterial skin infection that causes painful, red, and swollen skin. Over time, the skin can become permanently thickened and scarred, a condition known as atrophie blanche. Proactive management is the best way to avoid these outcomes.
