What is the leading cause of venous ulcers?

Venous ulcers are primarily caused by insufficient venous blood flow, which leads to increased pressure in the veins of the lower extremities. This elevated pressure can damage the surrounding tissue and inhibit proper healing, ultimately resulting in the formation of ulcers. Impaired venous return, commonly seen in conditions such as chronic venous insufficiency, causes stagnant blood to pool in the veins, leading to skin breakdown and ulceration.

Conditions like arterial obstruction or diabetes mellitus can certainly contribute to skin issues and ulcers, but they are not the leading cause of venous ulcers specifically. Infection may occur in existing venous ulcers but is not a primary factor in their development. Understanding that the root cause of venous ulcers lies in poor venous circulation highlights the importance of addressing venous health to prevent and manage these ulcers effectively.
