Why might amputation be frequently necessary for diabetics?

Amputation is frequently necessary for diabetics primarily due to necrosis and gangrene occurring in the feet and legs. Diabetes can lead to a variety of complications, including peripheral neuropathy, which results in decreased sensation in lower extremities. This lack of sensation makes it difficult for individuals to notice injuries or sores, allowing them to become infected and, over time, lead to tissue death (necrosis) or gangrene.

Additionally, poor circulation, which is common in diabetics, can further exacerbate issues related to healing. When the tissue becomes necrotic or develops gangrene, the only effective treatment may be amputation to prevent the spread of infection and to preserve the patient’s overall health. The severity of these conditions and the associated risk of systemic infection often necessitate such drastic surgical interventions to save the patient's life.
