How Diabetes Affects Your Feet

Nerve Damage (Peripheral Neuropathy)

Diabetic neuropathy occurs when elevated blood sugar damages nerves, most often in the feet. Reduced sensation makes it difficult to feel pain, pressure, or temperature changes. Symptoms may include numbness, tingling, burning, or sharp pains. Because injuries may go unnoticed, even small issues can worsen quickly.

Poor Circulation (Peripheral Arterial Disease)

Diabetes can reduce blood flow to the lower extremities. When circulation is limited, wounds heal more slowly, and infections are harder to fight. Poor circulation significantly increases the risk of diabetic foot ulcers and other complications.

Foot Deformities

Changes in muscles, bones, and joints may alter foot structure over time. Conditions like Charcot foot can cause instability, swelling, and changes in foot shape, leading to increased pressure points and a higher likelihood of skin breakdown.

Skin and Nail Changes

Diabetes often causes dry skin, thick calluses, and nail problems such as fungal infections. Cracked skin and untreated nail conditions can allow bacteria to enter, increasing the risk of infection.

Key Warning Signs to Watch For

Early detection is one of the most effective ways to prevent serious diabetic foot problems. Watch for:

• Numbness, tingling, burning, or persistent pain
• Cuts, blisters, redness, swelling, or slow-healing sores
• Dry or cracked skin
• Ingrown, thickened, or discolored toenails
• Feet that feel unusually cold or warm
• Changes in foot shape, swelling, or collapsed arches
• Shoes that rub, cause pressure, or suddenly feel uncomfortable

If you notice any of these symptoms, our expert podiatrist should evaluate your feet promptly.

Essential At-Home Foot Care Steps

Daily Foot Inspections

Check your feet every day, including the soles and between the toes. Look for cuts, discoloration, swelling, or changes in skin texture. A mirror or assistance from a family member can help with hard-to-see areas.

Proper Cleaning Habits

Wash your feet daily using lukewarm water and gentle soap. Hot water can cause burns or excessive dryness, especially if sensation is reduced. Dry thoroughly, paying close attention to the spaces between toes.

Protecting Your Feet

Avoid walking barefoot, even indoors. Wearing socks and well-fitted shoes helps prevent injuries that may otherwise go unnoticed.

Choosing Supportive Footwear

Diabetic-friendly shoes should provide cushioning, stability, and ample toe room without pressure points. Replace shoes when they become worn or lose support, as poorly fitting footwear is a common cause of ulcers.

Nail and Skin Care Safety

Trim toenails straight across and gently smooth edges. Avoid attempting to cut corns or calluses at home, as this can easily lead to wounds. Professional foot care is the safest option.

Supporting Healthy Circulation

Low-impact exercise, such as walking or swimming, can help improve blood flow. Avoid sitting for long periods, move your feet frequently, and elevate them when resting.

Safe Activity Choices

Choose activities that reduce repetitive pressure on the feet. High-impact exercises should be discussed with your podiatrist, especially if you have neuropathy or structural changes.

When to Contact Our Team

Signs That Require Immediate Attention

Contact our foot and ankle specialist right away if you experience:

• A wound that does not heal
• Redness, swelling, warmth, or drainage
• Sudden color or temperature changes in the foot
• Persistent or worsening pain
• Signs of infection spreading beyond the foot

Prompt treatment can prevent minor issues from becoming serious.

Routine Diabetic Foot Exams

Regular podiatry visits are essential for patients with diabetes. During a diabetic foot exam, your provider will assess circulation, nerve function, skin health, nail condition, and foot structure. These exams help identify problems early—often before symptoms become severe.

Reduced Sensation? When Nerve Damage Becomes Serious

Loss of sensation increases the risk of unnoticed injuries, which can lead to ulcers and infections. If you experience numbness or tingling, it’s important to inform your doctor. Diagnostic testing can confirm diabetic neuropathy, and ongoing monitoring helps reduce long-term complications.

Protect Your Feet with Preventive Care

Daily foot care and early treatment are key to preventing diabetes-related complications. Paying attention to changes and working closely with our specialists can help you maintain mobility and avoid unnecessary risks.
