Per example, a toe or even a leg

Simply put, if you have nerve damage (which diabetes can cause) you might not feel some things that happen to you. You can injure yourself seriously and not realize it because you’re not feeling the pain. The extremities are where this is most likely to happen.
Ergo, you don’t seek help, or don’t treat the injury seriously. So it gets worse. And it gets way worse. And while it should be rare, if a part of your body *dies* for whatever reason – typically loss of proper blood flow – it will rot on your body and cause you all kinds of health problems. At that point the solution is to remove the dead material, like by amputation.
Similar things can happen with other nerve damage diseases like leprosy.
