For individuals living with diabetes, foot health is not merely a matter of comfort—it's a critical component of overall well-being and disease management. Diabetes can significantly impact foot health through a combination of nerve damage (neuropathy) and reduced blood flow (peripheral vascular disease), creating a perfect storm for serious complications if proper care is neglected.

‍

At Diablo Foot & Ankle, we specialize in comprehensive diabetic foot care, focusing on prevention, early intervention, and effective treatment when problems arise. This guide explores the importance of proactive diabetic foot care, warning signs that require immediate attention, and strategies to maintain optimal foot health with diabetes.

‍

Understanding Diabetic Foot Complications: Why Early Intervention Matters

‍

Diabetes affects foot health through several mechanisms that can lead to serious complications if not properly managed.

‍

The Impact of Diabetes on Foot Health

‍

Diabetic Peripheral Neuropathy:

• Affects up to 50% of people with diabetes
• Causes numbness, tingling, or pain in the feet
• Reduces ability to feel injuries, pressure, or temperature
• Creates risk of undetected wounds or injuries
• May lead to changes in gait and foot structure

‍

Peripheral Arterial Disease (PAD):

• Narrowing of blood vessels reducing circulation to the extremities
• Affects 1 in 3 people with diabetes over age 50
• Slows healing of even minor injuries
• Increases risk of infection
• Can lead to tissue death (gangrene) in severe cases

‍

Autonomic Neuropathy:

• Affects sweat glands, leading to dry, cracked skin
• Creates entry points for infection
• Contributes to callus formation
• Alters normal moisture balance of the foot

‍

Immune System Dysfunction:

• Higher blood sugar impairs immune response
• Increases susceptibility to infection
• Reduces ability to fight infections effectively
• Contributes to slower healing

‍

The Progression of Diabetic Foot Problems

‍

Without proper care and early intervention, diabetic foot problems typically follow a concerning progression:

‍

Initial Stages:

• Minor skin changes (dryness, calluses)
• Small fissures or cracks in the skin
• Subtle changes in foot shape or pressure points
• Mild neuropathic symptoms

‍

Intermediate Concerns:

• Development of corns, calluses, or pressure points
• Formation of blisters or small wounds
• Changes in foot structure (Charcot foot early stages)
• Fungal infections or ingrown toenails

‍

Serious Complications:

• Non-healing ulcers
• Deep infections
• Bone infections (osteomyelitis)
• Charcot foot deformity
• Gangrene

‍

End-Stage Complications:

• Need for partial or complete amputation
• Systemic infection
• Life-threatening conditions

‍

The Critical Importance of Early Intervention

‍

The statistics regarding diabetic foot complications are sobering:

• 15-25% of people with diabetes will develop a foot ulcer in their lifetime
• 85% of diabetes-related amputations are preceded by foot ulcers
• After a lower extremity amputation, the five-year mortality rate is approximately 50%
• Up to 80% of these amputations are preventable with proper foot care and early intervention

‍

Early intervention breaks this progression by:

• Addressing minor issues before they become serious
• Preventing small wounds from becoming ulcers
• Treating infections before they reach deeper tissues
• Correcting biomechanical issues before they cause wounds
• Managing risk factors proactively

‍
