What Causes Leg Ulcers?

What are Leg Ulcers?

Leg ulcers are open wounds or sores, usually on the lower leg, that haven’t healed within six weeks. They most often develop due to underlying circulation problems, particularly in the veins, that reduce the flow of oxygen and nutrients to the skin, impairing the body’s ability to heal. Although more common in older adults or people with certain health conditions, leg ulcers can affect anyone. They often begin as a small cut, scratch, or skin break that doesn’t heal properly. Over time, these wounds can become larger, painful, and more difficult to manage without appropriate medical treatment. Venous ulcers are the most common type of leg ulcer, accounting for over 60% of leg ulcers according to NHS statistics.

With the right diagnosis and treatment, leg ulcers can be managed effectively and, in many cases, prevented from recurring. Early intervention is key to promoting healing and avoiding further complications.

Common Causes of Leg Ulcers

There are several causes of leg ulcers, including:

• Poor circulation
• Varicose veins
• High blood pressure in the leg veins
• Peripheral arterial disease (PAD)
• Diabetes
• Pressure from prolonged immobility
• Injuries or trauma to the leg

These conditions impair healing by reducing blood flow or causing fluid build-up, which weakens the skin.

How Do Leg Ulcers Start?

Most leg ulcers begin as minor cuts or injuries that fail to heal. Over time, poor blood circulation prevents oxygen and nutrients from reaching the damaged tissue, resulting in persistent wounds. In cases of venous insufficiency, the increased pressure within leg veins can lead to fluid building up in the surrounding tissue, which makes the skin weaker.

Can Varicose Veins Cause Leg Ulcers?

Yes. Varicose veins are one of the leading contributors to venous leg ulcers. When the valves in your leg veins don’t work properly, blood collects in the veins, increasing pressure and weakening the skin. If left untreated, this can lead to skin breakdown and ulceration.

What Are the Signs You Should Seek Help?

You should contact a vascular consultant if:

• A wound on your leg hasn’t healed after six weeks
