Nail ridges are common and often harmless features that many people notice but rarely think much about. However, recent insights from skin expert Dr. Ross Perry of Cosmedics reveal that these ridges might carry important clues about your overall health. While most nail changes are benign, certain types of ridges could signal nutritional deficiencies or even more serious medical conditions—making it essential to know when to pay attention and when to consult a healthcare professional.
Dr. Perry explains that some ridges arise from deficiencies in vitamins and minerals essential for nail health. “A lack of Vitamin A, or insufficient protein or calcium in your diet, may lead to ridges forming on your nails,” he said. “In more severe cases, iron deficiency anemia can cause noticeable nail changes such as pronounced ridges.” These subtle signs are the body’s way of indicating it might need better nutritional support. For many, improving diet or taking supplements can help nails regain a healthier appearance.
That said, Dr. Perry emphasizes that not all nail ridges are cause for alarm. Most nail changes do not reflect serious underlying problems and may result from everyday habits. The NHS supports this view, noting that nail issues like brittleness, loose nails, or changes in color or shape usually don’t indicate severe medical conditions. For example, repeatedly picking at nails or exposure to harsh chemicals can cause surface ridges and imperfections that are simply cosmetic.
However, some nail changes should prompt closer attention. Dr. Perry warns that “severe, deep ridges,” while rare, can be a sign of serious illness, including kidney disease. Diabetes is another condition known to cause changes in nail texture and appearance. Such pronounced ridges may be accompanied by other symptoms, and it’s important not to ignore these potential warning signs. When ridges are deep or accompanied by pain or discoloration, scheduling a doctor’s visit is wise.
Beyond ridges, there are other nail-related symptoms to watch for. If a nail becomes misshapen, discolored, or falls off without injury, medical advice is recommended. Likewise, soreness, redness, swelling, or warmth around the nail—known medically as paronychia—could indicate an infection or ingrown nail needing treatment. The NHS further suggests seeing a podiatrist if nails become too thick to cut or difficult to manage, as this can lead to complications if left unaddressed.
Ultimately, if you notice any unusual or persistent changes in your nails, your general practitioner is a good first point of contact. They can assess whether your symptoms stem from nutritional issues, infection, or other medical conditions, and guide appropriate treatment. For those looking for more information or self-care tips, the NHS website offers accessible resources on nail health and when to seek help.
Taking care of your nails might seem simple, but they can be valuable indicators of your overall health. From subtle ridges caused by minor vitamin shortages to more serious changes linked to systemic disease, paying attention to your nails is a small but important step in staying well. With proper care and timely medical advice, you can keep your nails—and yourself—in good health.
