Diabetes can cause circulation issues and nerve damage, which greatly affects the health of your feet. People with diabetes also have a higher risk of infection and muscle or joint issues. Poor circulation prevents oxygen and nutrients from making their way to your feet, which in turn makes it more difficult for blisters, cuts, and other wounds to heal. The longer cuts and other sores take to heal, the higher the risk of infection. Nerve damage in the feet, more commonly known as peripheral neuropathy
, may cause a variety of physical sensations, but it may also not be felt at all. While neuropathy often causes pain, tingling, and/or weakness in the feet, it also leads to a loss of feeling in the feet. Both poor circulation and peripheral neuropathy increase your chance of developing a foot ulcer and of that wound becoming infected. Foot ulcers precede the majority of diabetes-related amputations, so proper foot care is essential.
