What Is Diabetic Foot Disease?
Diabetic foot disease — or diabetic neuropathy — refers to circulatory and nerve problems affecting the feet of those with diabetes.
Some of these diabetic foot problems may include:
- Nerve damage
- Poor circulation
- Foot ulcers
- Diabetic foot infections
- Inflammations
What causes Diabetic Foot Disease?
Diabetes itself does not inevitably lead to diabetic foot disease. Chronic high blood sugar levels, demonstrated by hemoglobin A-1 C levels higher than eight over many years, lead to nerve damage to the feet.
Among those with diabetes, your risk for diabetic neuropathy is greater if you:
- Have type 1 diabetes
- Have type 2 diabetes
- Are older than 40 years of age
- Are a man
- Have high blood sugar levels
Diabetic foot disease risk factors
- Poor foot hygiene
- Poorly fitted or poor quality shoes
- Improper trimming of toenails
- Alcohol consumption
Complications of diabetic foot disease
Diabetes can damage your nerves and reduce blood flow to your feet. This may make it harder to notice if you have sustained some sort of minor foot injury, like a blister or a sore.
A minor injury can escalate to a more serious diabetic foot infection, which may require amputation.
Because of this, those with diabetes are 25 times more likely to lose a leg than those without the disease.
How can I prevent diabetic foot disease?
- Stay physically active, at least 30 minutes most days of the week.
- Consult a nutritionist or certified diabetes educator (CDE) for meal planning advice.
- Quit smoking.
- Keep your blood pressure and cholesterol within a healthy range.
- Maintain a healthy weight.
How common is diabetic foot disease?
Diabetic neuropathy is common for people with diabetes.
What Are the Signs and Symptoms of Diabetic Foot Disease?
Most people with diabetic foot disease do not feel a great deal of pain.
More common diabetic foot disease symptoms may include:
- Swelling of the feet.
- Redness of the feet concentrated in areas of pressure.
- Blisters.
- Sores.
- Tingling or burning sensation.
- Weakness in muscles.
- Sharp pain.
- Cramps.
When should I see a doctor about my diabetic foot disease?
Make an appointment with your doctor if you notice any of these symptoms:
- Changes in skin color on the foot.
- Swelling in the foot or ankle.
- Have pain or swelling in the feet that does not improve after two to five days of at-home treatment.
How Do You Diagnose Diabetic Foot Disease?
The American Diabetes Association (ADA) recommends a yearly total foot exam for all those with diabetes.
Your doctor or other specialist can conduct the exam. He or she will check for bone skin imperfections and abnormalities, which are often precursors to diabetic foot disease or diabetic neuropathy.
To confirm a diagnosis of diabetic foot disease, your doctor will fully review your:
- Symptoms.
- Medical history.
- Results of a number of tests and exams.
How Do You Treat Diabetic Foot Disease?
Since diabetic foot disease has no known cure, treatments at UPMC Orthopaedic Care aim to:
- Slow the progression.
- Preserve and restore function to the foot.
- Manage and prevent related complications.
- Relieve pain.
Our doctors use a range of treatments in cases of diabetic foot disease or diabetic neuropathy, including:
- Medications.
- Nonsurgical treatments.
- Surgery.
Medications
Medications for diabetic foot disease may include pain relievers, like anti-seizure medications, and antidepressants.
While these medications are often used for treating other conditions, they have been proven to help with nerve pain.
Nonsurgical treatments for diabetic foot disease
The two most common nonsurgical treatments are casting and custom shoes.
Casting can help protect the foot and ankle bones while reducing swelling.
During casting treatment for diabetic neuropathy:
- You will likely use crutches, walkers, or even wheelchairs.
- Your doctor will change your casts often to monitor the foot's shape.
Custom shoes can help:
- Fit the shape of a diabetic foot.
- Decrease the risk of further health problems like foot ulcers.
Surgery for diabetic neuropathy
Orthopaedic experts at UPMC often advise surgical treatment methods for patients that:
- Are at a greater risk of getting foot ulcers.
- Have not had success using nonsurgical treatment options for their diabetic foot disease.
Some of the more common surgical strategies for diabetic foot disease include:
- Muscle lengthening.
- Bone shaving.
- Fusion of bones.
- Repositioning of bones.
- Amputation, in cases of severe infection.
Benefits and risks of diabetic foot disease treatment
Treatments for diabetic foot disease, when implemented quickly, can be effective in preserving and even restoring function. For that reason, it's vital for all people with diabetes to regularly monitor their feet and control sugar intake.
Following any sort of surgery for diabetic foot disease, you will have to avoid all weight bearing activities for about three months.
Failure to follow doctors' orders of this rest period can lead to further problems and related complications.
