My grandma has suffered from diabetes for tens of years and her blood glucose level is relatively stable now. She fell over while taking a walk a few days ago and her leg is black and blue all over.She has been worried about it and fear that it would result in a "diabetic foot".

Diabetic patients have been told by their doctors that they are susceptable to infection and their hands and feet are particularly susceptible because blood circulation is poorest at the extremities. It is crucial for people with diabetes to thoroughly check their hands and feet for cracks, cuts, or any other injuries so that wounds can be cared for immediately to prevent infections.

1.Daily care:
Cleaning the skin thoroughly, especially on the feet,is important for making sure nothing has come in contact that could damage the skin and potentially lead to infection.
Moisturize the skin regularly, with specific focus on the extremities (feet, hands),as dry skin is easy to be cracked in which infection.

2.If injured
Clean the injured area to remove any dirt or debris. Use antiseptic wash to relieves pain and fight germs. Ensure open skin area is thoroughly cleaned with sterile gauze pads. Try gauze pads or a clean cloth.Treat the wound with an antibiotic ointment to help prevent the wound from infection.Protect the area completely.To firmly secure pad in place and to help seal out dirt and germs, wrap the covered wound with a gauze wrap.

3.Stablize glucose level
It is vital to maintain your glucose level in the range to help your wound to restore.High glucose level is beneficial for bacterias and infection would become more difficult to control, even with antibiotics.
