Diabetic foot infection

Diabetic foot infection

Diabetic foot infection is the most common complication of diabetes. This is caused by having too much glucose in the blood for a long period of time. If not taken care of, diabetic foot infections can cause serious problems, including amputation.

Causes of diabetic foot infection

Foot infections mostly occur when the nerves in the feet are damaged. This happens when blood glucose levels are not managed properly and remain too high. Damaged nerves in the feet can cause tingling, pain, weakness or a loss of feeling. This condition where the nerves in the feet are damaged is called neuropathy. Also, diabetes causes low blood circulation. Without good blood circulation, it will take longer for a cut or sore to heal. This is called peripheral vascular disease.


Because of the lack of feeling in the feet, people with diabetes may not notice small sores or cuts. It’s possible to have a small stone stuck in the shoe and walk on it all day without knowing it. A lot of people with diabetes won’t notice a foot injury until the skin breaks and becomes infected.
If not looked after properly, a foot infection can lead to amputation of the foot. This is also the case when there is a low flow of blood in the foot. Diabetic foot infections will not heal properly or not at all causing gangrene.


Proper foot care can help prevent diabetic foot infections and also treat them before turning into serious complications. It’s important to check the feet daily for cutes, sores and blisters. Washing the feet every day with lukewarm water is a good method for a daily check.
Moisturizing the feet with a lotion or crème is important to skin from becoming dry and cracked. Furthermore, it’s recommended to wear proper shoes that are comfortable. Regular appointments with a pedicurist can help in taking proper care of the feet.
