What Is Diabetic Foot?

Diabetic foot refers to foot problems that arise due to long-term high blood sugar levels in people with diabetes. These problems can affect the skin, nerves, blood vessels, and bones of the feet.

Over time, poorly controlled diabetes can lead to:

• Nerve damage (diabetic neuropathy)

• Poor circulation (peripheral artery disease)

• Foot ulcers and infections

If ignored, these complications can result in serious outcomes such as gangrene or limb amputation.

H2: Common Causes of Diabetic Foot

H3: 1. Diabetic Neuropathy

This condition results in loss of sensation in the feet due to nerve damage. You might not feel a blister, cut, or sore—leading to infections that go unnoticed.

H3: 2. Poor Blood Circulation

High blood sugar narrows and hardens blood vessels, especially in the legs and feet. This slows down wound healing and increases the risk of infection.

H3: 3. Foot Deformities and Improper Footwear

Structural changes like bunions, hammertoes, or flat feet can cause friction and pressure. Poorly fitting shoes can worsen the problem, leading to calluses and ulcers.

H3: 4. High Blood Sugar Levels

Uncontrolled glucose impairs the body’s natural healing response and weakens the immune system, making even minor injuries dangerous.

H2: Diabetic Foot Complications

Untreated symptoms can lead to serious complications:

• Foot Ulcers: Open wounds that are slow to heal and prone to infection

• Cellulitis: A bacterial skin infection that spreads quickly

• Abscesses: Pockets of pus under the skin

• Gangrene: Tissue death brought on by a reduction in blood flow
  

• Charcot Foot: Weakened bones in the foot that may fracture or dislocate

• Amputation: Sometimes necessary if infection spreads or tissue dies

H2: Diabetic Foot Diagnosis and Treatment

H3: Diagnosis

A healthcare provider may:

• Inspect your feet for sores, infections, and deformities

• Perform a monofilament test to check sensation

• Use a Doppler ultrasound to assess blood flow

• Order X-rays or MRIs for bone involvement

H3: Treatment Options

Condition	Treatment
Minor cuts/blisters	Antibiotic ointments, dressings, foot elevation
Foot ulcers	Debridement, specialized shoes, wound care
Infections	Oral or IV antibiotics, sometimes surgery
Charcot foot	Casts, custom footwear, orthopedic surgery
Severe cases	Amputation and prosthetic care

H2: Lifestyle Habits That Support Foot Health

• Control blood sugar: Keep A1C levels in range (typically below 7%)
