Diabetic Foot

Diabetic Foot Problems

Not only does diabetes require patients to constantly monitor their blood glucose level, but patients must also examine their feet everyday in order to prevent infections that can lead to open wounds or even amputation. In the feet and lower legs, diabetes can cause poor circulation through the hardening of arteries as well as nerve problems that affect a patients’ ability to feel correctly. Without consistent observation, diabetic feet may not heal properly from minor injuries or constant rubbing from poorly fitting shoes. Other foot abnormalities such as hammertoe, athlete’s foot, or even ingrown toenails should be treated as serious issues.

Patients with diabetes should have regular visits with one of our physicians at American Foot and Leg Specialists. However, symptoms in the feet and lower legs like persistent pain, swelling, hard shiny skin, pus, red streaking, new or lasting numbness, minor trauma, or a new blister/ulcer/wound need to be addressed immediately by one of our board certified podiatry specialists.

Common Diabetic Foot Complications

The two most common complication that lead to foot infections in diabetics are:

Diabetic Neuropathy: Diabetic neuropathy occurs as a result of uncontrolled diabetes and results in the loss of feeling in the feet. This loss of feeling becomes particularly problematic when a blister, cut, ulcer, or similar complication develops on the foot and a patient cannot detect the complication. The blister, cut, ulcer, or other complication can then go undetected for some time and become infected before it is properly addressed.

Peripheral Artery Disease: Diabetes can result in peripheral artery disease which leads to reduced blood flow to the feet (peripheral refers to the extremities away from the heart). Poor blood circulation to an injury or irritation of the foot can make it difficult for even the smallest cut or sore to heal leading to infection or other serious complications.

Diabetic Foot Amputations

Diabetes is the single greatest cause of non-traumatic leg amputations. The risk of leg and foot amputations significantly increases for those who have diabetes compared to those who do not. Furthermore, evidence suggests that around 80% of these amputations can be avoided with early detection and proper foot care. Due to neuropathy and the associated lack of feeling, early detection can be difficult. Combining the lack of feeling associated with neuropathy and the lack of blood flow with peripheral artery disease, undetected and slow healing infection can result in amputation of a toe, foot, or entire leg.

In light of the serious nature of such foot complications, it is important to maintain proper foot care and see our physicians at American Foot and Leg Specialists routinely if you have diabetes.

Treatment for Diabetic Foot Complications

Exercise is often times recommended as a way of improving circulation throughout the body, including the feet and legs, though one should consult one of our physicians before starting any exercise regimen. As previously mentioned, most diabetic complications are avoidedable with effective foot care. This includes wearing properly fitted shoes (ask our physicians about prescription shoes that are covered by Medicare), not going barefoot, performing regular self-examinations of your feet, wearing stockings that improve blood circulation, and other similar forms of care.
