Diabetic Wound Care

What Is a Diabetic Foot Ulcer?

A wound is generally considered chronic when it has not progressed meaningfully through the normal stages of healing in about four weeks or has not fully closed in about six to eight weeks. Chronic wounds include diabetic foot ulcers, venous leg ulcers, arterial ulcers, pressure injuries, surgical wounds that have dehisced, and wounds related to radiation, trauma, or autoimmune conditions.

Why Diabetic Wounds Are Different

Understanding why a diabetic foot wound requires special care starts with recognizing the unique factors that affect healing and increase the risk of complications.

• Loss of protective sensation: Nerve damage reduces the pain signals that normally cause us to protect an injury.
• Peripheral artery disease: Reduced circulation slows oxygen and nutrient delivery to healing tissue.
• Immune changes: Elevated blood sugar impairs white-cell function and raises infection risk.
• Foot structure changes: Stiff joints and pressure points create the mechanical stress where ulcers form and recur.

Risk Factors

• Diabetes with neuropathy or loss of protective sensation
• A prior diabetic foot ulcer or lower-extremity amputation
• Peripheral artery disease (PAD)
• Foot deformities such as bunions, hammertoes, or Charcot foot
• Calluses, fissures, or poor-fitting shoes
• Chronic kidney disease
• Tobacco use

Signs and Symptoms

• A sore, blister, callus, or open wound on the foot
• Drainage staining socks or bed linens
• Swelling, warmth, or redness of the foot or ankle
• An unusual odor from a foot wound
• A change in foot shape, new warmth, or swelling without injury  

How In-Home Diabetic Foot Ulcer Care Works

A complete diabetic wound care at home plan addresses both the wound and the underlying causes that led to its development. Our specialists provide:

• Comprehensive assessment: Wound measurement, photography, and sensation testing.
• Circulation check: We coordinate vascular testing (ABI, toe pressures, or duplex) with your physician when circulation may be inadequate for healing.
• Wound bed preparation: Sharp or conservative debridement of callus and nonviable tissue as clinically appropriate and ordered.
• Dressings: Appropriate dressings selected for exudate, depth, and infection status.
• Infection management: Close monitoring for cellulitis, deep-tissue infection, or osteomyelitis, and coordination of antibiotics when ordered.
• Medical optimization: Blood sugar, nutrition, and medication coordination with your diabetes team.
• Education: Self-care education, daily foot checks, and caregiver teaching.

Advanced Therapies

When a diabetic foot ulcer has not progressed as expected after several weeks of standard care, your physician may add advanced therapies such as negative-pressure wound therapy,  tissue-based products (skin substitutes), or low-frequency noncontact ultrasound (UltraMIST). We help coordinate and deliver these therapies at home when ordered and medically appropriate. Outcomes depend on many factors, including circulation, glycemic control, offloading adherence, and the specific wound.

Frequently Asked Questions

How long does a diabetic foot ulcer take to heal?

Healing times vary widely. Many uncomplicated diabetic foot ulcers heal within 12–20 weeks with consistent offloading, good blood-sugar control, and adequate circulation. Deeper wounds, wounds with infection, or wounds with poor circulation can take longer or may need surgical intervention. Your provider will set realistic expectations based on your specific situation.

Do I really need a total contact cast?

For many plantar diabetic foot ulcers, a non-removable offloading device is the most effective way to heal. Your provider will discuss options, including total contact casts, removable walkers made non-removable, and other alternatives, based on the ulcer location, your circulation, and what you can safely tolerate.

Can I still walk with a diabetic foot ulcer?

Activity should be limited and done only with appropriate offloading. Walking on an ulcerated foot without offloading is one of the most common reasons diabetic foot ulcers fail to heal. We will review what level of activity is safe based on your wound and offloading device.

What should I check on my feet every day?

Look at the tops, bottoms, sides, and between the toes of both feet every day, using a mirror or a family member’s help if needed. Watch for new redness, blisters, cuts, swelling, color changes, or warmth. Any new finding on a diabetic foot deserves a same-week clinical check  or sooner if you have warning signs.

Does diabetic wound care stop once the ulcer closes?

Closing the wound is only the first milestone. Because recurrence rates are high in the first year after healing, ongoing prevention such as protective footwear, regular foot exams, callus management, and blood-sugar control is an important part of long-term care.
