Diabetes and Foot Health: 5 Warning Signs You Shouldn't Ignore

November is Diabetes Awareness Month, an important reminder that managing diabetes involves more than monitoring blood sugar. One area that deserves special attention is foot health.

Diabetes can affect the nerves, circulation, and healing process in your feet, making even minor injuries more difficult to recognize or recover from. Over time, these changes can also contribute to problems that affect your ability to walk and stay active.

Understanding the warning signs, practicing preventive foot care, and knowing when to seek medical attention can help protect your feet and long-term mobility.

How Does Diabetes Affect Your Feet?

Diabetes can affect foot health in several ways, particularly through nerve damage and circulation problems.

Nerve Damage (Diabetic Neuropathy)

Over time, elevated blood sugar can damage the nerves in your feet and legs. This condition, called diabetic peripheral neuropathy, may cause numbness, tingling, burning sensations, or reduced sensitivity to pain and temperature.

When sensation decreases, you may not notice a blister, cut, or injury right away. Without the usual warning signs of pain, minor problems can worsen before they are discovered.

Reduced Circulation and Slower Healing

Diabetes can also increase the risk of peripheral artery disease (PAD), a condition that reduces blood flow to the legs and feet. Poor circulation can make it harder for wounds to heal and for the body to fight infection.

When nerve damage and circulation problems occur together, even a small foot injury can become more serious if left untreated.

Learn more about these complications from the Centers for Disease Control and Prevention (CDC).

5 Foot Changes People With Diabetes Shouldn't Ignore

Regularly checking your feet can help you recognize potential problems before they become more serious. Here are five changes worth paying attention to:

1. Numbness, Tingling, or Burning

Changes in sensation may indicate diabetic neuropathy. If you experience persistent tingling, burning, or reduced feeling in your feet, contact your healthcare provider for an evaluation.

2. Cuts, Blisters, or Wounds That Aren't Healing

A small blister or cut may seem harmless, but diabetes-related nerve damage and healing concerns can increase the risk of infection. New wounds, open sores, or injuries that aren't healing should be evaluated promptly.

3. Changes in Skin Color or Temperature

Unusual redness, discoloration, or changes in foot temperature may signal circulation problems, infection, or another underlying condition. These changes should not be ignored, particularly when they appear suddenly.

4. Swelling or Changes in Foot Shape

New swelling, warmth, or changes in the structure of your foot may indicate a problem involving the bones or joints.

In some people with diabetic neuropathy, these symptoms can be associated with Charcot foot, a serious condition in which weakened bones and joints can become damaged, sometimes without significant pain. A newly swollen, warm, or misshapen foot requires urgent medical evaluation, and you should avoid putting weight on it until assessed.

5. Persistent Foot or Ankle Pain

Ongoing pain, stiffness, or difficulty walking may be related to an injury, arthritis, tendon condition, or another orthopedic concern. An evaluation can help identify the cause and determine appropriate treatment.

When Does Orthopedic Foot & Ankle Care Come Into Play?

While diabetes management typically involves your primary care physician, endocrinologist, and other healthcare professionals, certain foot and ankle problems may benefit from orthopedic evaluation.

Orthopedic foot and ankle specialists focus on conditions affecting the bones, joints, ligaments, tendons, and overall structure of the foot and ankle.

For patients with diabetes, orthopedic care may be appropriate for:

• Foot and ankle injuries: Fractures, sprains, and other injuries that may require imaging, immobilization, or additional treatment.
• Persistent pain or limited mobility: Ongoing discomfort, stiffness, or instability that makes walking or daily activities difficult.
• Changes in foot structure: Conditions such as bunions, hammertoes, or other deformities that may affect alignment, footwear, and mobility.
• Suspected Charcot foot: A serious bone and joint condition that requires urgent assessment, protection from weight-bearing, and coordinated specialist care.

At 360 Orthopedics, foot and ankle evaluations may include a physical examination, diagnostic imaging, and an individualized treatment plan.

Depending on the condition, treatment options may include bracing, immobilization, orthotic devices, physical therapy, or surgery when necessary.

It's important to recognize that not every diabetes-related foot concern requires orthopedic care. New wounds, infections, circulation problems, and changes in sensation should be promptly evaluated by the appropriate medical professional. Sudden severe circulation changes or rapidly worsening infections may require emergency care.

How Can You Protect Your Feet When You Have Diabetes?

Taking a few simple steps each day can help protect your feet and reduce the risk of complications.

The American Diabetes Association recommends several important foot care practices:

• Inspect your feet daily. Check for cuts, blisters, redness, swelling, or changes in your skin and nails.
• Choose supportive, properly fitting shoes. Avoid footwear that rubs or creates unnecessary pressure.
• Keep your feet clean and dry. Wash with warm water, dry carefully between your toes, and moisturize dry skin while avoiding lotion between the toes.
• Avoid walking barefoot. Protective footwear can help prevent injuries you may not immediately feel.
• Attend regular foot examinations. Your healthcare team can monitor changes in sensation, circulation, and skin health.
• Manage your diabetes consistently. Work with your primary care physician or endocrinologist to manage blood sugar and other factors that affect healing and circulation.

If you notice a new wound, swelling, or unusual change in your feet, don't wait until your next routine appointment to seek medical advice.

Frequently Asked Questions

Can diabetes cause foot and ankle problems?

Yes. Diabetes can contribute to nerve damage, reduced circulation, and slower wound healing. It may also increase the risk of certain foot complications, including structural changes that affect the bones and joints.

When should someone with diabetes see a foot and ankle specialist?

An orthopedic foot and ankle evaluation may be appropriate for persistent pain, injuries, fractures, joint problems, or structural changes. Sudden swelling, warmth, or suspected Charcot foot requires urgent medical assessment rather than a routine appointment.

Can foot injuries be more serious for people with diabetes?

Yes. Reduced sensation can make injuries harder to notice, while poor circulation and healing problems can increase the risk of infection and other complications. Even minor wounds should be taken seriously.

Can physical therapy help with foot and ankle conditions?

Physical therapy may help improve strength, mobility, balance, and function for certain orthopedic foot and ankle conditions. Your healthcare provider can determine whether rehabilitation is appropriate based on your diagnosis and overall foot health.

Does 360 Orthopedics treat diabetes?

360 Orthopedics provides orthopedic evaluation and treatment for foot and ankle conditions, not primary diabetes management. Patients should continue working with their primary care physician, endocrinologist, and other appropriate healthcare professionals to manage diabetes and related complications.
