Why do diabetics get gangrene?

Gangrene is a serious complication that can affect people with diabetes, as well as those without. The condition is caused by impaired blood circulation to the affected body part, resulting in tissue death due to inadequate oxygen and nutrients. In diabetics, this occurs when their high blood sugar levels damage small blood vessels in the extremities such as their feet and fingers (called peripheral vascular disease). Over time, these damaged vessels start to harden, constricting the flow of oxygenated or nutrient-rich blood needed for healthy functioning of tissues. Without adequate nutrition or oxygen being delivered to them, these tissues become vulnerable to infection and break down – leading to progression of diabetes-related gangrene.

In addition to poor circulation from peripheral vascular disease caused by elevated glucose levels in diabetes patients’ blood streams, other factors contributing towards gangrene include injury/trauma accompanied by bleeding which accelerates tissue breakdown; chronic alcohol abuse; advanced age; smoking habits; obesity; autoimmune disorders such as lupus; prolonged exposure and infection due to poor hygiene practices like not changing bandages regularly and keeping wounds clean.

Diabetic patients experiencing painless / tenderness developing in their extremities should consult their healthcare provider immediately for diagnosis and treatment. Such individuals should also take preventive measures such as controlling glycemia levels through diet & exercise ; adopting lifestyles practices like stopping smoking , avoiding alcohol etc . These simple steps can help reduce risk of progression towards complications associated with diabetic gangrene while allowing you healthier life ahead !
