Diabetes and Your Feet
When you were diagnosed with diabetes, your doctor and other health care providers probably talked with you about this health condition and gave you educational materials to help you better understand the impact this disease has on your body. This book focuses specifically on the foot problems faced by people with diabetes. Like all complications of diabetes, foot problems are better controlled when your blood sugar is controlled.
Chronically elevated blood sugars cause damage to your nerves and blood vessels. The smallest arteries, called arteri¬oles, that circulate blood to your extremities and organs, become narrowed or blocked. When this happens, the nerves that the arteries serve are deprived of the fresh oxygenated blood and nutrients needed to function normally. Over time, the nerves will fail.
The results of nerve failure include loss of vision, loss of kidney function, and loss of protective sensation for pain in the foot, also known as "diabetic sensory neuropathy." This condition leaves your foot vulnerable to painless or silent trauma that can lead to foot ulcers, infections, hospitalizations and amputations. So, if you do a good job of controlling your blood sugars, you will be less likely to develop foot problems.
The foot is a very sturdy structure. You need healthy feet to remain active and independent. While everyone's feet are subject to physical forces, stresses, and deformities, people with diabetes must be even more vigilant about foot care. As a person with diabetes, your body responds differently to than the average person and you are at higher risk to develop complications. Please, don't take your feet for granted. It's better to know than to be sorry.

Many people say that depression is a side effect or complication of diabetes. Without discounting the association of the psychological condition with the physical one, I'm not convinced that our high and/or unstable glucose levels are directly responsible for that change in our mental state. My belief is that the unrelenting need for self-care, for following the sort of care schedules that can drive licensed, professional caregivers crazy, is what overwhelms us...
