Sparing the details, a colleague of mine recently had his big toe amputated due to diabetes. I wondered why being diabetic could lead to this as it’s common.

Diabetes impacts your circulation and your nerves. High blood sugar causes arteries to harden reducing blood flow. Less blood means less nutrients and oxygen, and your feet are already one of the worst parts of your body for circulation. Nerve damage due to blood sugar fluctuations means your body can’t feel damage, which reduces your natural healing response.
End result is a double whammy of poor healing response and a lack of nutrients and oxygen, which, if severe enough, leads to gangrene and amputation.
