Did you know your nails can reveal clues to your overall health? A touch
of white here, a rosy tinge there, or some rippling or bumps may be a
sign of disease in the body. Problems in the liver, lungs, and heart can
show up in your nails. Keep reading to learn what secrets your nails
might reveal.
Pale Nails
Very pale nails can sometimes be a sign of serious illness, such as:
- Anemia
- Congestive heart failure
- Liver disease
- Malnutrition
White Nails
If the
nails are mostly white with darker rims, this can indicate liver
problems, such as hepatitis. In this image, you can see the fingers are
also jaundiced, another sign of liver trouble.
Yellow Nails
One of
the most common causes of yellow nails is a fungal infection. As the
infection worsens, the nail bed may retract, and nails may thicken and
crumble. In rare cases, yellow nails can indicate a more serious
condition such as severe thyroid disease, lung disease, diabetes or
psoriasis.
Bluish Nails
Nails
with a bluish tint can mean the body isn't getting enough oxygen. This
could indicate an infection in the lungs, such as pneumonia. Some heart
problems can be associated with bluish nails.
Rippled Nails
If
the nail surface is rippled or pitted, this may be an early sign of
psoriasis or inflammatory arthritis. Discoloration of the nail is
common; the skin under the nail can seem reddish-brown.
Cracked or Split Nails
Dry,
brittle nails that frequently crack or split have been linked to
thyroid disease. Cracking or splitting combined with a yellowish hue is
more likely due to a fungal infection.
Puffy Nail Fold
If
the skin around the nail appears red and puffy, this is known as
inflammation of the nail fold. It may be the result of lupus or another
connective tissue disorder. Infection can also cause redness and
inflammation of the nail fold.
Gnawed Nails
Biting
your nails may be nothing more than an old habit, but in some cases
it's a sign of persistent anxiety that could benefit from treatment.
Nail biting or picking has also been linked to obsessive-compulsive
disorder. If you can't stop, it's worth discussing with your doctor.
