Dry skin and brittle nails are often dismissed as minor beauty issues, but they can signal deeper health concerns, according to Dr. Sai Lahari Rachumallu, an Associate Consultant in Dermatology at Manipal Hospital in Bhubaneshwar, India. Hormones play a crucial role in skin moisture and nail strength, and changes in hormone levels can manifest externally. Conditions like hypothyroidism, characterized by an underactive thyroid, can lead to dry, flaky skin and fragile nails. Symptoms may include fatigue and weight gain, which develop gradually. Additionally, hormonal shifts during pregnancy and menopause can temporarily alter skin and nail quality. Nutritional deficiencies, particularly low iron and vitamin B12, are also significant contributors. Environmental factors, such as harsh soaps and dry climates, can further damage skin and nails. Recognizing persistent symptoms alongside other body changes is essential for early medical intervention. Simple daily care routines, including using ceramide-based moisturizers and maintaining hydration, can significantly improve skin and nail health. Overall, these external signs may reflect internal health, making awareness vital for overall wellbeing.
