Diabetes and Your Feet: What New U.S. Data and Guidelines Mean for Preventing Amputations

Why this still matters in 2026

Most diabetes-related amputations start with a small, preventable foot wound. And despite decades of progress in diabetes care, lower-extremity amputations remain a serious public health problem in the United States.

Recent surveillance reports from the Centers for Disease Control and Prevention (CDC), including analyses published in MMWR, show that thousands of Americans with diabetes still lose a toe, foot, or leg each year. These are observational trend data, meaning they track patterns over time rather than proving cause for any one person. But the trends are clear: amputation rates remain higher among older adults, people with long-standing diabetes, and communities facing barriers to care.

CDC reporting and peer-reviewed studies in journals such as JAMA Network also document persistent disparities. Black Americans, Native communities, people living in rural areas, and those who are uninsured or underinsured experience higher rates of diabetes-related lower-extremity amputations. Researchers consistently point to differences in access to preventive care, specialty services, and early treatment—not biology—as key drivers.

The American Diabetes Association (ADA) 2025–2026 Standards of Care do not describe a new breakthrough. Instead, they reinforce and refine prevention strategies that are already known to reduce risk when applied consistently and early.

How diabetes damages the feet

According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), two main problems put feet at risk:

Peripheral neuropathy (nerve damage), which reduces the ability to feel pain, heat, or pressure.
Peripheral artery disease (poor circulation), which limits blood flow needed for healing.

When blood sugar stays high over time, nerves can lose function. A blister from a tight shoe, a small cut, or a callus may go unnoticed because it doesn’t hurt. At the same time, reduced blood flow slows healing and weakens the body’s ability to fight infection.

This combination—loss of feeling plus poor circulation—creates a dangerous situation. A minor wound can turn into a foot ulcer (an open sore). If bacteria enter and infection spreads to deeper tissue or bone, amputation may be required to stop life-threatening complications.

The CDC emphasizes that many of these amputations are preventable with early detection and timely treatment.

Warning signs you should not ignore

People with diabetes should contact a clinician promptly if they notice:

Numbness, tingling, or burning in the feet
A sore or blister that does not begin to heal within a few days
Redness, warmth, swelling, or drainage
Thick calluses with bleeding underneath
Blackened or blue skin (possible tissue death)
Sudden severe pain, or a pale, cold foot

Seek urgent care for spreading redness, pus, fever, blackened tissue, or sudden changes in color or temperature. These can signal a serious infection or loss of blood flow.

What the ADA 2025–2026 Standards recommend

The ADA’s 2025–2026 Standards of Care—an evidence-based clinical guideline updated annually—outline practical steps that reduce amputation risk. Key recommendations include:

1. Annual comprehensive foot exams

Every person with diabetes should receive a thorough foot exam at least once a year. This includes checking skin integrity, foot shape, pulses, and sensation using simple tools such as a monofilament test.

2. Risk stratification and more frequent checks

People with neuropathy, previous ulcers, deformities, or peripheral artery disease need more frequent foot evaluations—sometimes every 1 to 3 months.

3. Early ulcer treatment

Prompt wound care, pressure relief (offloading), and infection management are essential. Evidence from clinical studies shows that early, coordinated treatment reduces the chance that an ulcer will progress to amputation.

4. Glucose, blood pressure, and cholesterol control

Maintaining blood sugar in target range slows nerve and vessel damage. Blood pressure and cholesterol management also protect circulation. These recommendations are supported by large randomized trials showing reduced complications with improved control, though no single target eliminates risk entirely.

5. Smoking cessation

Smoking worsens circulation. The ADA stresses that quitting smoking is one of the most important steps a person with diabetes can take to protect their limbs.

6. Multidisciplinary care

Studies cited in ADA guidance show lower amputation rates when care teams include primary care clinicians, podiatrists, vascular specialists, and wound-care professionals. Access to this kind of coordinated care is not equal nationwide, which contributes to disparities.

Access and insurance: What about therapeutic shoes?

Properly fitted footwear reduces pressure points that can lead to ulcers. Under Medicare Part B, therapeutic shoes and inserts may be covered for people with diabetes who meet specific criteria—such as documented neuropathy, foot deformity, or prior ulcers—and whose clinician completes required certification, according to the Centers for Medicare & Medicaid Services (CMS).

Coverage is not automatic. It depends on eligibility, documentation, and participation by qualified suppliers. Out-of-pocket costs can still apply. Patients should ask their primary care clinician or diabetes specialist whether they qualify and how to begin the process.

Who is at higher risk—and why

CDC surveillance and peer-reviewed studies consistently show higher amputation rates among:

Older adults
People with long-standing diabetes
Black Americans and Native communities
Residents of rural areas
People without stable insurance coverage

These differences are strongly linked to structural factors such as delayed diagnosis, fewer specialty providers, transportation barriers, and limited access to preventive services. Observational data cannot assign blame to individuals. Instead, they highlight gaps in access and continuity of care.

What’s working—and what remains uncertain

Multidisciplinary limb-preservation programs, early screening, and aggressive ulcer management have reduced amputation rates in some health systems. However, national data show uneven progress.

It remains uncertain how quickly updated guidelines alone can reverse long-standing disparities. Insurance coverage, workforce shortages in podiatry and vascular surgery, rural hospital closures, and social determinants of health all influence outcomes. Researchers continue to study which system-level changes produce the largest sustained reductions in amputations.

What this means for readers

Most diabetes-related amputations begin with a small, preventable wound.
Check your feet daily if you have diabetes.
Get a professional foot exam at least once a year—and more often if you are high risk.
Seek care quickly for sores that do not heal, spreading redness, drainage, fever, or blackened skin.
Keep blood sugar, blood pressure, and cholesterol under control.
Quit smoking if you smoke.
Ask whether Medicare or your insurer covers therapeutic shoes if you qualify.

Amputations are not inevitable. Early action—by patients, clinicians, and health systems—remains one of the most effective ways to protect mobility, independence, and overall health.
