And a alter in color or size of this characteristic may indicate an underlying disease, Linder explains.

For instance, if the lunula extends almost to the end of the nail, making the majority of the nail white in color except for a narrow band at the acme, information technology could signal cirrhosis, chronic renal failure or congestive heart failure.

And in patients with severe kidney affliction, it's non uncommon to encounter half-and-half nails, where the white from the lunula extends halfway up the boom bed, and the other half of the smash is darker in color, says Richard H. Flowers, M.D., assistant professor of dermatology at the University of Virginia.

Pitted nails

An abnormal boom shape and blast surface can also indicate a wellness effect. For example, nails that are dimpled or pitted — "like somebody took a pen and just pressed it in and information technology made an imprint," Flowers says — can point to psoriasis, a chronic peel disease. Psoriasis can besides cause the nails to loosen and separate from the blast bed, as can thyroid affliction.

While rare, melanomas can appear on or effectually the fingernail (so be sure to check the peel around your nail, too). And unlike heart affliction, kidney disorders and other conditions, melanoma doesn't commonly cause other noticeable symptoms, Flowers says — the color of your blast could be your only clue.

Less dire is a yellow discoloration of the nails. This syndrome tin can announced in patients with chronic bronchitis and other lung diseases. Fungus, besides, can turn the nails xanthous, though this is more than common in toenails than fingernails, the Mayo Clinic says.

Thin and brittle nails may merely demand some TLC

If your nails are sparse and brittle, a thyroid disorder may be to blame, or it may exist that they merely demand more moisture.

"Nosotros always tell our patients that but similar your skin tends to dry out and sparse and lose its ability to retain wet, the nails exercise the same affair," Flowers says. And, equally with the skin, nails can absorb moisture, which is why he recommends rubbing them with Vaseline when they feel dry out. "And that tin kind of help preclude some of the corking and splitting" from normal wear and tear, he says.

Wearing gloves when you do the dishes or clean with chemicals can also preclude nails from condign brittle. Another way to keep them in elevation shape is by eating a well-balanced diet.

One thing Flowers doesn't recommend, however, is the nutritional supplement biotin, which is often touted for its ability to strengthen frail nails. Flowers argues that there's not much evidence to indicate it helps. And taking information technology in supplement grade can "significantly interfere with sure lab tests and crusade incorrect results that may go undetected," the Nutrient and Drug Administration notes in an advisory to the public — including tests that diagnose heart attacks. It's always best to consult a medico before adding whatsoever new over-the-counter drug or supplement into the mix.
