What is a common characteristic of venous ulcers?

Venous ulcers are commonly characterized by their irregular borders and the tendency to produce exudate. This stems from the underlying pathology of venous insufficiency, which leads to increased venous pressure and resultant skin changes. The skin around the ulcer may appear discolored, and the ulcer itself often has a shallow level with a moist, weeping surface. The irregular shape contrasts with arterial ulcers, which typically have well-defined edges and are usually more painful.

The exudative nature of venous ulcers can also result from the inflammatory processes associated with venous stasis and can be indicative of ongoing tissue damage and the body's attempt to heal. Such characteristics help differentiate venous ulcers from other types, such as arterial ulcers or diabetic ulcers, which have different presentations and underlying causes. Understanding these features is important for effective diagnosis and management in geriatric physical therapy settings.
