Chronic Venous Hypertension: Symptoms, Management and Leg Health in the UK

Chronic venous hypertension is a long-term condition where the blood pressure within the veins of the legs remains consistently high. In a healthy circulatory system, one-way valves in the veins ensure that blood flows upwards towards the heart, even against the pull of gravity. When these valves become damaged or weakened—a condition known as venous valvular incompetence—blood can pool in the lower legs.

This pooling increases the internal pressure (hypertension) within the veins. Over time, this pressure forces fluid and blood cells out of the vessels and into the surrounding tissues, leading to the characteristic swelling and skin changes associated with the condition. It is a progressive condition often linked to Chronic Venous Insufficiency (CVI) and is a leading cause of mobility issues and skin ulceration in the UK population.

Symptoms often develop gradually and may be dismissed as simple tiredness or age-related aches. However, early recognition is vital for preventing permanent skin damage. Key symptoms include:

• Oedema: Persistent swelling in the feet and ankles, which is often worse at the end of the day or after long periods of standing.
• Heavy Legs: A sensation of fullness, heaviness, or throbbing in the lower limbs.
• Skin Discolouration: Reddish-brown patches (haemosiderin staining) appearing around the ankles.
• Varicose Veins: Visible, twisted, or bulging veins on the surface of the legs.
• Venous Claudication: Pain in the legs that occurs specifically when walking and is relieved by rest and elevation.
• Lipodermatosclerosis: Hardening or thickening of the skin, making the leg look like an 'inverted champagne bottle'.

Several factors contribute to the breakdown of vein valves and the subsequent rise in venous pressure. According to NHS guidance, these include:

Age and Genetics

The risk increases as we age because the veins lose elasticity. A family history of varicose veins or CVI also significantly increases your likelihood of developing the condition.

Obesity

Carrying excess weight puts additional pressure on the veins in the lower body, making it harder for blood to be pumped back to the heart.

Occupational Hazards

Jobs that require long periods of standing (such as retail or nursing) or prolonged sitting can lead to blood pooling, as the 'calf muscle pump' is not being utilised to move blood upwards.

Previous Deep Vein Thrombosis (DVT)

A past blood clot can damage the delicate valves within a vein, leading to 'post-thrombotic syndrome', a frequent precursor to chronic venous hypertension.

Management of chronic venous hypertension follows NICE (National Institute for Health and Care Excellence) pathways, focusing on reducing pressure and improving flow. The primary treatments include:

• Compression Therapy: This is the 'gold standard' for management. Specially fitted compression stockings apply graduated pressure to the leg, assisting the valves and reducing oedema.
• Leg Elevation: Patients are advised to elevate their legs above the level of their heart for 20-30 minutes several times a day to encourage venous return.
• Exercise: Activities like walking or calf raises help stimulate the calf muscle pump.
• Skin Care: Using emollients to keep the skin hydrated prevents the cracking and itching (varicose eczema) that can lead to infection.

In more severe cases, a GP may refer you to a vascular specialist for procedures such as endothermal ablation or sclerotherapy to close off damaged veins.

Managing a long-term condition like chronic venous hypertension requires consistent monitoring. You should consider booking a consultation to speak to a GP online if you notice any of the following:

• Your leg swelling is no longer resolving overnight.
• You have developed new, itchy, or red patches of skin on your lower legs.
• You are experiencing pain that interferes with your daily walking or sleep.
• You need advice on the correct grade of compression hosiery.
• You require a review of your current management plan or a referral to a specialist.

An online GP can assess your symptoms via video link, review your medical history, and provide prescriptions for medicated creams or specialist stockings, as well as issue sick notes if the condition affects your ability to work.

The most serious complication of chronic venous hypertension is the development of a venous leg ulcer. These are chronic sores that take more than two weeks to heal. Because the high pressure in the veins prevents healthy oxygenated blood from reaching the skin, even a small scratch can turn into a significant wound. Maintaining healthy circulation through weight loss, smoking cessation, and consistent use of compression is the best way to avoid these difficult-to-treat ulcers.
