Medical experts are urging patients with diabetes to shift their focus toward early prevention, warning that the onset of diabetic foot complications occurs long before a visible ulcer ever appears.
The Silent Progression of Nerve and Vascular Damage
According to specialist Dr. Manuel de Jesús, the condition is not a sudden event but a progressive process. He warns that diabetic foot starts much earlier
than the appearance of an open sore, beginning instead with the gradual deterioration of the nerves and blood vessels in the lower extremities.
This progression is primarily driven by two factors: neuropathy and ischemia. Neuropathy occurs when high glucose levels damage the nerves, leading to a loss of sensation. Simultaneously, ischemia restricts blood flow to the feet, which impairs the body’s ability to heal small injuries. Together, these conditions create a dangerous scenario where a patient may suffer an injury without feeling it, while the lack of circulation prevents the wound from closing.

Identifying Early Warning Signs
Because the loss of sensation can be subtle, Dr. Manuel de Jesús emphasizes the importance of recognizing early physical changes in the feet. These signs often serve as the first indicators that the disease is progressing:
- Extreme dryness of the skin.
- The formation of calluses or corn.
- Changes in the shape or alignment of the foot.
- Sensations of tingling or numbness.
When these early symptoms are ignored, a simple blister or a small cut can quickly evolve into a deep ulcer. If left untreated, these ulcers can lead to severe infections and, in advanced cases, may necessitate amputation.
Preventative Strategies and Daily Care
To mitigate these risks, healthcare providers recommend a rigorous daily care routine. This proactive approach is critical for maintaining mobility and preventing permanent disability.
Key preventative measures include:
- Daily Inspections: Patients should examine their feet every day for redness, swelling, or small cuts, using a mirror to see the soles if necessary.
- Skin Hydration: Keeping the skin moisturized is essential to prevent cracking, though specialists advise avoiding the application of creams between the toes to prevent fungal infections.
- Appropriate Footwear: Wearing shoes that fit properly and avoiding walking barefoot to prevent unnoticed injuries.
- Glycemic Control: Maintaining stable blood sugar levels to gradual the progression of nerve and vascular damage.
This emphasis on early detection underscores a broader public health challenge: the need for diabetic patients to view foot care as a daily necessity rather than a response to an existing wound. By addressing the precursors to ulcers, patients can significantly reduce the risk of severe complications.
