What Causes Skin Ulcers?
Skin ulcers, also known as open sores, develop due to a combination of factors, primarily stemming from impaired blood circulation and/or prolonged pressure on the skin. Let's explore these in detail:
-
Poor Blood Circulation: This is a major contributor. Insufficient blood flow prevents efficient delivery of oxygen and nutrients to the skin, hindering the healing process. Minor injuries that would normally heal quickly can instead develop into ulcers.

-
Prolonged Pressure: Continuous pressure on a particular area of the skin, such as from prolonged immobility, restricts blood flow to the tissues. This lack of oxygen and nutrients weakens the skin, leading to breakdown and ulcer formation. [Reference: Medical News Today, Healthline]
-
Infection: Once an ulcer forms, it becomes highly susceptible to infection, potentially exacerbating the condition and delaying healing. [Reference: idatb.com]
Secondary Contributing Factors:
-
Previous Injuries: Even seemingly minor injuries can develop into ulcers, particularly in individuals with poor circulation or other underlying health issues. [Reference: NHS, NHS inform]
-
High Pressure in Leg Veins (Venous Insufficiency): This commonly contributes to venous leg ulcers. Weakened veins lead to fluid buildup and increased pressure in the legs, damaging the skin and making it prone to ulceration. [Reference: NHS, NHS inform, MedlinePlus, Hopkins Medicine]
Types of Skin Ulcers:
Different types of skin ulcers exist depending on the underlying cause. Examples include venous ulcers (most common type in the leg), arterial ulcers, and diabetic ulcers. Understanding the specific type is crucial for effective treatment. [Reference: Various sources cited above detail different ulcer types although not explicitly listed.]
Early Treatment is Key:
Addressing ulcers early is vital to prevent infection and promote healing. Treatment typically involves wound care, managing underlying conditions (such as improving circulation or diabetes control), and sometimes surgery. [Reference: Medical News Today, Healthline]
