Understanding Your Diabetic Foot Ulcer (DFU)
Diabetes can cause serious problems with your feet1

Diabetes is a condition in which your body does not properly turn the food you eat into energy.1 Normally, the body produces a type of sugar called glucose after you eat or drink. For this sugar to get into the cells of your body and be used for energy, a hormone called insulin is needed.

Foot Icon For people with diabetes, the body is not able to make enough insulin. This causes sugars to build up in the blood. Over time, high blood sugar can lead to numbness and other problems with your feet. It also results in poor blood flow. Because of this, you might step on a sharp object and not even feel it.2

These foot problems can result in a wound that is slow to heal and may become infected. Doctors call these kinds of sores diabetic foot ulcers, or simply DFUs.1,2
