Which factor is a common cause of gangrene necrosis?

Gangrene necrosis occurs when tissues die due to a lack of blood supply and subsequent oxygen deprivation. Arteriosclerosis, which refers to the thickening and hardening of artery walls, is a significant contributor to reduced blood flow in the arteries, leading to ischemia. This is particularly relevant in areas prone to lower blood circulation, such as extremities, which can result in tissue death and gangrene.

In contrast, increased blood flow is not a factor that causes gangrene, as sufficient blood circulation typically helps maintain tissue health. Low blood pressure may contribute to inadequate perfusion in specific circumstances, but it does not define the underlying conditions leading to gangrene directly. Hyperglycemia, while it can complicate healing and contribute to vascular issues over time, is not a direct cause of gangrene necrosis itself. Therefore, arteriosclerosis is the most pertinent factor associated with this type of necrosis, as it directly impairs blood flow crucial for tissue viability.
