What your nails say about your health

Fungal nail infections

Fungal infections - whether it's athlete's foot, vaginal thrush or that sore, itchy rash in your groin or under your breasts - very commonly affectyour skin.

Thrush is caused by a fungal infection, from yeasts which normally live harmlessly on all our skins. But if a fungus gets into your nails, it can be difficult to get rid of. The main symptoms are thickened, flaky, discoloured nails - often your toenails.

If your doctor thinks a fungus may be to blame, they will probably send a clipping from your nail to the laboratory. Over the counter medicines containing amorolfine 5% can work on nails but can take months. If the infection is on multiple nails, you may need to take a tablet a day for three to six months to get rid of the infection. Fortunately, it may be unsightly but it's harmless.

Psoriasis

Little pits in your nails are common. Very occasionally, they can be a sign of a condition called psoriasis. We usually think of psoriasis as a skin condition which causes red patches - but in a few people, the main symptom is joint pain. It's worth talking to your doctor if you have persistent or unsightly pits in your nails.

Clubbing

No, not partying late into the night, but swelling of the end portion of the fingers, along with curving over of the fingernails. It's sometimes described as 'drumstick fingers' because of the swelling.

Usually linked to lung or heart conditions, along with inflammatory bowel diseases such as Crohn's and ulcerative colitis, or primary biliary cirrhosis, it definitely needs checking out.

White spots

I've lost count of the number of people who've told me they're short of calcium because they have white spots or lines on their nails. In fact, it's nothing to do with this. It's probably simple bashes and bangs to your nails.

The best thing you can do is to stop worrying - and maybe protect your nails to prevent it happening again. It's very common in gardeners and DIY enthusiasts. The spots or lines will gradually grow out to the ends of your nails and then disappear.

Ingrowing toenails

Ingrowing toenails usually affect the side of your big toe. The nail starts to grow into the flesh at the side of your nail, and can cause a serious infection.

Prevention

This can often be treated with antibiotic creams or tablets. Occasionally, it keeps coming back, and you may need a minor operation to remove part or your entire toenail.

These measures will also reduce your chance developing bunions too. Finally, if you find it hard to cut your own toenails, talk to your doctor about a referral to your local chiropody or toenail cutting service.
