The skin, the body’s largest organ, can offer subtle but significant clues about diabetes. Individuals with diabetes often experience dry, itchy skin due to dehydration resulting from frequent urination, a hallmark of the condition. Furthermore, the presence of acanthosis nigricans – dark, thickened patches of skin, typically in body folds – can indicate insulin resistance, often a precursor to type 2 diabetes. Additionally, individuals with diabetes are more susceptible to fungal infections, which thrive in a high-sugar environment.
