Feet are supplied with blood to keep them healthy and have a large number of nerves to detect pain and act as an early warning system for potential injury. For example, if you have a stone in your shoe, nerves will send a message to your brain to remove the stone and hence prevent injury to the feet. However, if your diabetes is poorly controlled for a long period of time it may result in nerve damage.
Nerve damage, termed peripheral neuropathy, which reduce sensation to the feet and / or reduce blood supply as damage to the blood vessels occurs.
Nerve damage may mean that you no longer notice small objects like a stone in your shoe, due to loss of sensation to your feet. This could then lead to a wound or injury that you cannot feel, and a possible infection.
If you have poor circulation, any injuries or infections to your feet, even seemingly minor, will take longer to heal as there is less blood flowing into the arteries in your feet.
Blood provides energy to working muscles and aids in healing damaged or injured tissue. If you have poor circulation, you will need to take extra care to protect your feet from injury. Most foot problems in people who have diabetes occur when injuries, and often infections, go unnoticed and untreated, and when healing is delayed due to poor circulation.
