A leading skin expert is raising awareness about what the ridges on your nails may signal and when it’s important to seek medical advice. Dr. Ross Perry of Cosmedics explains that subtle nail changes are often linked to nutritional deficiencies, dehydration, or underlying skin conditions. According to him, missing key nutrients can impact nail texture and strength. He notes that “a lack of Vitamin A, or low levels of protein or calcium, may contribute to ridges,” and in more severe cases, iron deficiency can cause noticeable alterations in nail appearance. These signs are easy to overlook, but they can offer valuable clues about your health.

Even so, most nail ridges are harmless, and Dr. Perry stresses that people shouldn’t panic when they notice minor imperfections. Habits like picking at nails or everyday wear and tear can create small grooves that don’t point to any serious condition. The NHS supports this view, explaining that common nail issues—including brittleness, color changes, or slight shape variations—rarely signal a major medical problem. They emphasize that “most nail issues are typically not linked to serious health concerns,” helping reassure those who may worry over minor changes.

However, experts warn that certain types of ridges deserve closer attention. Dr. Perry highlights that deep, pronounced ridges may be a sign of an underlying illness, such as kidney disease or diabetes, and should not be ignored. These conditions can affect nail growth patterns, making the presence of severe ridges a potential early indicator. Being aware of these shifts can help you recognize when something might be wrong and prompt you to seek timely medical evaluation.

It’s always wise to consult a healthcare professional if you notice major changes, such as nails becoming misshapen, unusually discolored, or falling off without explanation. Pain, redness, swelling, or warmth around the nails could signal infections like paronychia and require medical care. The NHS also advises seeing a podiatrist if nails become too hard to trim or difficult to reach. If you’re worried about your nails or unsure about the cause of a recent change, visiting your GP and reviewing NHS resources can help you stay informed and protect your overall health.
