Diabetic foot complications surge in Brazil, raising amputation risk

Diabetic foot disease, a severe complication of diabetes, results from progressive nerve and vascular damage that often progresses silently. Because loss of sensation prevents pain detection, small cuts, blisters or calluses can develop into chronic wounds, deep infections and, in severe cases, require amputation. The Brazilian Diabetes Society reports that peripheral neuropathy accounts for roughly two‑thirds of non‑traumatic amputations nationwide.

A ten‑year study covering 27 Brazilian capitals recorded more than 45,000 diabetic‑foot complications, a number that more than tripled between 2008 and 2018. Specialists stress early detection: "Many patients come to the office without knowing they had a foot wound. The loss of sensitivity makes small lesions go unnoticed for a long time," said podiatrist Dr. Micheline Sarquis. She also advises daily self‑inspection and regular specialist evaluations. Updated 2025 guidelines recommend that people with diabetes avoid walking barefoot, even at home, and wear properly fitted shoes to reduce risk.

These measures aim to curb the rising trend and prevent unnecessary amputations among Brazil’s growing diabetic population.
