In what way can I avoid an amputation?

Amputation. The single best thing that a diabetic can do to help prevent amputations is to control their blood sugar levels. The second thing is to make sure that you are checking your feet every day and are wearing appropriate foot wear and socks. Both of these things can be accomplished by finding a clinician and professional to assist you with the management of your disease.
Professional care. Diabetic foot ulcers and infection may often times be prevented with good diabetic foot education and foot care by a professional, tight sugar control, good nutrition, frequent foot inspection and use of properly fitting shoes.
