Diabetes can cause a number of complications in the feet referred to as diabetic foot. Damage to small peripheral nerve endings in the feet can lead to neuropathy causing a loss of sensation in the feet. The loss of feeling means that people suffering from the diabetic foot may be unable to detect sores or injuries to the feet. They may also experience numbness, tingling, or a burning sensation in the feet.
Diabetes can sometimes lead to a reduction in blood supply to the feet, causing cramps in the legs amongst other issues. It also delays healing and can make people with diabetes more prone to infection following cuts or wounds to the skin.
The diabetic foot examination is designed for early detection of Diabetic Neuropathy and Peripheral Vascular Disease, both serious conditions that can lead to eventual amputation of limbs.
