Your feet are supplied with blood to keep them healthy. They also have a multitude of nerves that act as an emergency warning system. For example, if you have a stone in your shoe, nerves will send a message to your brain to investigate. However, if your diabetes is poorly controlled for a long period of time, this may lead to:
- Nerve damage, or "peripheral neuropathy", which impairs sensation to the feet.
- Reduced blood supply, also known as "poor circulation".
Nerve damage may mean that you no longer notice the stone in your shoe, due to loss of sensation to your feet. This could then lead to an injury you can't feel, and possibly infection.
