Simple Skin Test May Prevent Foot Ulcer Recurrence

Scientists supported by the National Institutes of Health (NIH) have found a new way to help predict if a diabetic foot ulcer will come back after healing. The study used a test called trans-epidermal water loss (TEWL), which measures how much water escapes through the skin. This tells doctors how well the skin is working as a barrier. People with high TEWL readings at the site of a healed ulcer were nearly three times more likely to have the wound return within 16 weeks, compared to those with lower readings.

These findings show that even if a foot ulcer looks healed, the skin might still be weak and at risk of breaking down again. By using this test, doctors can better identify patients who are more likely to have the ulcer come back. This could help guide follow-up care and prevent serious complications, like infections or amputations. Dr. Teresa Jones from the NIH says this tool could play an important role in improving care for people with diabetes.
