How Can Diabetes Damage My Feet?

As a podiatrist, I encounter many patients who are unaware of how diabetes can affect their feet beyond managing blood sugar levels. Diabetes is a complex condition that not only impacts blood sugar regulation but also significantly affects the circulatory and nerve systems, especially in the feet. Understanding these effects is crucial for preventing serious complications and maintaining optimal foot health. Let’s explore how diabetes can affect your circulatory and nerve systems and what you can do to protect yourself.

Circulatory System:

  1. Reduced Blood Flow (Peripheral Vascular Disease): Diabetes can lead to a condition known as peripheral vascular disease (PVD), where blood flow to the extremities, particularly the feet and legs, is reduced. This occurs due to damage to blood vessels caused by high blood sugar levels over time.
  2. Implications for Foot Health: Poor circulation means that wounds and infections heal more slowly. It also increases the risk of developing peripheral artery disease (PAD), which can lead to blockages in the arteries supplying the legs and feet. This reduced blood flow makes it harder for your body to fight infections and can result in tissue damage or even amputation if not managed properly.
  3. Symptoms: Symptoms of poor circulation in the feet may include cold feet, changes in skin color, and slow-healing wounds or ulcers. It’s essential to monitor these symptoms and seek medical attention promptly if you notice any changes.

Nerve System:

  1. Diabetic Neuropathy: High blood sugar levels can damage the nerves throughout the body, but diabetic neuropathy most commonly affects the feet and legs. This condition can cause various symptoms:
  • Peripheral Neuropathy: Numbness, tingling, or burning sensations in the feet and legs.
  • Autonomic Neuropathy: Affecting involuntary functions such as heart rate, digestion, and bladder control.
  • Proximal Neuropathy: Pain, weakness, or muscle wasting, typically in the thighs, hips, or buttocks.
  1. Impact on Foot Health: Diabetic neuropathy reduces sensation in the feet, making it difficult to detect injuries such as cuts, blisters, or ulcers. Without prompt treatment, these minor injuries can lead to serious infections or foot deformities.
  2. Preventive Measures: Regular foot exams by a podiatrist are crucial for detecting early signs of diabetic neuropathy. Managing blood sugar levels, maintaining a healthy lifestyle, and wearing appropriate footwear are essential for preventing or delaying nerve damage.

Protecting Your Feet:

  1. Diabetes Management: Keeping blood sugar levels within a target range recommended by your healthcare provider is essential for preventing or delaying complications affecting the circulatory and nerve systems.
  2. Foot Care Routine: Establish a daily foot care routine, including inspecting your feet for cuts, blisters, or changes in skin color. Wash your feet daily with lukewarm water and mild soap, and moisturize to prevent dry skin.
  3. Regular Podiatric Visits: Schedule regular visits with a podiatrist who specializes in diabetic foot care. They can assess your foot health, provide preventive care, and address any concerns or complications promptly.
  4. Healthy Lifestyle Choices: Maintain a healthy weight, eat a balanced diet, quit smoking if you smoke, and engage in regular physical activity. These lifestyle choices can improve circulation and overall health.


Diabetes affects more than just blood sugar levels—it impacts the circulatory and nerve systems, particularly in the feet. By understanding these effects and taking proactive steps to manage your diabetes and prioritize foot care, you can reduce the risk of serious complications and maintain optimal foot health. Remember, your feet are your foundation for mobility and independence—take care of them, and they will take care of you!
