If you have an ulcer on your foot and it is not healing, there would be number of causes or reasons for the same. Diabetes may be a significant reason. If there are wounds, redness, pain, swelling or discolouration, always consult a doctor at the earliest. A diabetic foot ulcer is a wound that occurs on your foot and is spotted in people suffering with diabetes. This type starts with a small injury like dry skin, small cut or a blister. These do not heal over the time and can lead to further infection and can bring some serious complications. The most important risk factor is diabetic peripheral neuropathy which is a condition where the nerves get damaged due to diabetes.

The other reason for diabetic foot ulcers is Peripheral Artery Disease (PAD) which is a condition where the arteries in the legs witness a blockage. More than 15 to 25 percent of the people across the globe develop diabetic foot ulcers. They are preventable. The symptoms are not obvious.
