Diabetes-related neurological ulcers identified as cause of chronic non-healing wounds

Medical experts are warning about the dangers of misdiagnosing chronic lower limb ulcers, which can lead to severe complications or amputation if not treated correctly. A case study involving a 60-year-old patient highlighted how a simple foot injury failed to heal for six months, eventually being diagnosed as a diabetic neurological ulcer by Dr. Wang Yu-an of Chi Mei Hospital.

Chronic ulcers are categorized into three main types: venous, arterial, and neurological. Venous ulcers are often caused by poor blood return, frequently affecting pregnant women, obese individuals, or those in professions requiring long periods of standing. Neurological ulcers, common in diabetic patients, are particularly dangerous because nerve damage can result in a loss of sensation, meaning patients may not realize they have been injured until the wound has significantly worsened.

To prevent complications, doctors recommend stable blood sugar control, wearing appropriate footwear, and avoiding walking barefoot. For difficult-to-heal wounds, low-level laser therapy is noted as a non-invasive option that can help improve microcirculation and stimulate biological responses to aid healing.
