Why nail diseases can be signs of more serious problems

Nail diseases are more common than you might think, and your nails could be showing symptoms of a broader health condition. Here are some tips to help you get to know your nails like the back of your hand.

Brittle nails are a common symptom of many nail diseases. The causes could be dehydration, psoriasis or repeated exposure to the chemicals in nail polish, nail polish remover and acrylic nail extensions. Here are some solutions:

• Wear gloves when doing household chores
• Apply nourishing oils to the nails, such as jojoba oil, or apply a nail hardener containing vitamin A and E
• Choose a diet rich in B vitamins, iron and zinc, which are essential for strong nails

Grooves can be the result of an inflammation of the pinkish nail bed that you can see through your nail. The ridges may just be a sign of age, something like wrinkles on the skin. Whatever the cause, don’t use a nail file to smooth the nail surfaces. Filing away the ridges may make your nails look nicer, but it will weaken them in the long run. Instead, apply a repairing serum that fills the grooves.

Are your nail tips peeling away in layers? Are they too dry or too soft? Fragile nails don’t take well to excessive moisture or extreme cold. Cover your hands in the winter, and take vitamin supplements to stimulate the synthesis of keratin, which is essential to the development of your nails. Avoid further traumatizing your nails with a nail file as well.

Nail diseases say a lot about your health and your habits. As you’ll see below, sometimes they’re signs of serious health problems, in which case you should see a doctor right away.

• Yellow nails. If the yellow isn’t from smoking cigarettes, then it could be a fungal infection. Nail fungus affects one in 10 people, making it the most common nail disease.

• Pale nails. Whitish nail beds aren’t a good sign. They could indicate circulatory problems, anemia, liver dysfunction or kidney troubles.

• Bluish nails. Were your nails bruised by a blow? If not, their colour could be a sign of a lack of oxygen and thus an indicator of respiratory failure or cardiovascular problems.

• White spots on the nails. Those little white spots on your nails are actually signs of trauma. You may have knocked or pinched your finger weeks ago, or you may have gone a bit too heavy with the manicure products. Contrary to popular belief, these spots aren’t caused by a lack of calcium or other minerals.

• Black nails. If the colour doesn’t disappear within a few days, see a doctor. This discolouration could be caused by melanoma.

Whenever your nails change drastically in appearance, you should pay attention. Any irregularities may be a sign of nail disease or something more serious.
