Understanding What Diabetic Foot Is
Diabetic foot is a complication of diabetes in which damage to nerves and blood vessels affects the feet. Long-standing high blood sugar levels impair sensation and reduce blood flow, making the feet vulnerable to injury and infection.
Because pain sensation is reduced, small cuts or blisters may go unnoticed. Without proper care, these minor injuries can progress into ulcers or deep infections. Understanding diabetic foot at an early stage helps prevent serious complications.

How Diabetes Affects the Feet
Diabetes damages nerves, a condition known as diabetic neuropathy, which reduces sensation in the feet. Patients may not feel pain, heat, or minor injuries.
At the same time, diabetes causes narrowing of blood vessels, leading to poor circulation. Reduced blood supply slows healing and increases the risk of infection.
How Diabetic Foot Develops Over Time
Diabetic foot usually develops gradually. Initial nerve damage leads to numbness, while poor circulation causes dry skin and cracks.
Minor injuries occur due to pressure, ill-fitting footwear, or walking barefoot. Because healing is slow, wounds enlarge and may become infected.
Why Diabetic Foot Often Goes Unnoticed Early
Early diabetic foot changes may not cause pain due to loss of sensation. Patients may ignore dryness, cracks, or calluses, assuming they are minor problems.
Without regular foot inspection, early signs are easily missed. This delay allows wounds to worsen and become chronic.
Early Changes and Warning Signs of Diabetic Foot
Early signs include numbness, tingling, burning sensation, or reduced sensitivity in the feet. Skin may appear dry, cracked, or shiny.
Swelling, redness, or small wounds that do not heal are warning signs that require medical evaluation.
