What ridges on your nails mean

Dr Ross Perry says that while normally nothing to worry about, the lines could indicate a number of issues - from deficiency to dehydration - as a result of a skin condition

A skin expert has revealed what the ridges on your nails mean and when it could be time you went to see your doctor.

Dr Ross Perry says that the lines could indicate a number of issues - from deficiency to dehydration - as a result of a skin condition. The doctor, of skin clinic chain Cosmedics, said: "Nutritional factors such as deficiencies in vitamins such as Vitamin A, or if your body is low in protein or calcium then you may notice ridges. Severe iron deficiencies could also create ridges and other changes to the nails."

But there's one difference that means you should call your GP immediately. He added: "Severe, deep ridges albeit rare could be a symptom of a more serious medical condition such as kidney disease and would need medical tests to determine the cause. Diabetes could also be the underlying health reason for this."

However most of the time, we don't need to worry as something as simple as picking at your nails can also cause the ridges. "Nail problems are not usually caused by anything serious," the NHS says. "Common nail problems include brittle, loose nails that may change colour or shape."

But if you experience any changes to your fingernails, it's important to seek medical attention. The health experts warn you should seek medical attention if "a nail has changed shape, changed colour or fallen off and you do not know why".

They also recommend seeing a GP if "the skin around your nails has become sore, red, swollen and warm (paronychia), which can be a sign of an infection or ingrown toenail. And you should have to see a podiatrist if "your nails are too tough to cut or you cannot reach them".

If you are concerned about your nails, visit your GP for advice. You can also get plenty of handy information on the NHS website.
