​Diabetes can significantly impact the feet due to complications stemming from high blood sugar levels. Over time, elevated glucose can lead to peripheral neuropathy, a condition where the nerves in the feet become damaged. This results in reduced sensation, making it difficult for patients to feel injuries, cuts, or blisters. Without proper sensation, minor injuries can go unnoticed and potentially lead to serious infections. Additionally, diabetes can cause poor circulation, which impairs the body's ability to heal wounds efficiently. This combined with nerve damage creates a higher risk for developing ulcers or infections that can be slow to heal.

Furthermore, diabetes can contribute to structural changes in the feet, such as Charcot foot, where the bones become weakened and deformities can develop due to joint damage. The altered biomechanics from these changes can increase the risk of foot injuries and calluses. For patients with diabetes, regular foot care is crucial to prevent complications and maintain overall foot health. Monitoring for any changes and seeking prompt medical attention for foot problems can help manage and mitigate these risks effectively.
