Manicures can make nails look neat and polished, but experts warn that nail polish can’t cover up signs of possible health problems.
According to the National Library of Medicine (NCBI), changes such as ridges or stripes on the nails can sometimes signal underlying conditions affecting the liver, lungs, or heart. While some nail changes are harmless or age-related, others may point to nutrient deficiencies or more serious medical issues.
Doctors say it’s important to pay attention to your nails — they often reflect what’s happening inside the body. If you notice new or unusual markings that don’t go away, it’s best to consult a healthcare professional for proper evaluation.
