Diabetes is extremely prevalent in the United States. The Centers for Disease Control and Prevention (CDC) report that over 10% of the US population has this chronic disease, and 26.8% of older adults (65 and over) are impacted by diabetes, both diagnosed and undiagnosed.1

Overview of Diabetes and Its Effects

Diabetes is a disease that results in abnormally high levels of blood glucose. Diabetes occurs when the pancreas does not produce enough (or any) insulin or when the body cannot properly use the insulin that is being produced. Some signs of diabetes may include increased urination, thirst, and hunger. Numbness and tingling in the legs and feet (also known as neuropathy) may occur. Loss of sensation (impaired sensory perception) may also occur in the lower extremities, most commonly below the knees. Dry skin, fatigue, and delayed wound healing can also be signs of diabetes. As with most medical conditions, these signs and symptoms can also indicate other illnesses, so it’s always best to follow up with your medical provider if you’re experiencing anything out of the ordinary.

In addition to diabetes, many patients have comorbidities, as well as complications of this chronic disease. Diabetes can impact major organs, especially when it is untreated or poorly controlled, and it may lead to damage of the nervous system, heart, kidneys, eyes, skin, and feet, among other issues.

Diabetic patients, especially older adults, are at risk for skin complications of diabetes, specifically diabetic foot ulcers (DFUs). As a result of neuropathy and impaired sensory perception, patients with diabetes may not always feel an initial injury, an ill-fitting shoe, or minor trauma from nail trimming or callous cutting. These issues can trigger a DFU.

Diabetic Foot Inspections

The best treatment for DFUs, as with many chronic illnesses, is prevention. Checking your patient’s feet and encouraging them to routinely check their own feet are the best ways to prevent a DFU or to keep a small injury from turning into a DFU. Routine skin checks, hygiene, appropriate fitting footwear, and not going barefoot are just a few ways to prevent DFUs.2 Additionally, routine exams should be scheduled for diabetic foot care as needed, with prevention of skin issues being the goal.

It is important to teach patients the correct way to check their feet, routine foot hygiene, and when to call their provider. If a skin issue arises, it is important to follow-up with a medical provider as soon as possible – early intervention is also key.

As nurses, it is important to understand the link between diabetes and foot care, risk factors, prevention, and evidence-based practices. Nurses with an interest in foot care, prevention, and diabetes education are able to seek out certifications in these specialties and be designated as experts in the field.

Conclusion

As with any chronic disease or illness, controlling the cause and managing it appropriately are key. Prevention is the best practice, but not everything is preventable. With foot care and diabetes, skin checks cannot be emphasized enough in terms of prevention of additional complications.
