Ever wonder why your nails are so brittle, yellow, or otherwise discolored?
Though you may not know it, these seemingly harmless symptoms may indicate you have some underlying health issues.
According to John Anthony, MD, a dermatologist at the Cleveland Clinic in Ohio and Debra Jaliman, MD, a New York City-based dermatologist and author of “Skin Rules,” there are certain nail symptoms that definitely shouldn’t be ignored. Here’s what eight different nail conditions are signaling about your health.
1. Yellow Nails
According to
WebMD, one of the most common causes of yellow nails is a fungal
infection. But in rare cases, they also say that it can indicate a more
serious condition such as diabetes, thyroid disease, or lung disease.
Smoking can also stain the nails yellow.
2. Cracked or Brittle Nails
Dr. Jailman says cracked or brittle nails can be a sign that the nail plate is extremely dry. The condition has also been linked to thyroid disease. Hypothyroidism sometimes causes this side effect as well.
3. Pitted Nails
According
to MedicineNet, nail pitting is caused by the defective development of
the layers of the nail plate, and it is common for those suffering from
psoriasis.
4. Ridged Nails
Dr. Anthony explains that
the reason people will see horizontal ridges on their nails is that
there could be direct trauma to the nail, or it could also be a cause of
a more serious illness, in which case you’ll see it on more than one
nail. That’s because the body is focusing it’s energy on fighting the
illness rather than the nails.
5. Discolored or Dark Lines Beneath
According
to WebMD, discoloration or a dark line on the nail can sometimes be
caused by melanoma, the most dangerous type of skin cancer. Melanoma can
also cause a black line or stripe on the nail. It’s important to visit
your doctor as soon as possible if you notice this.
6. Bitten Nails
According
to Medical Daily, the American Psychiatric Association’s Diagnostic and
Statistical Manual of Mental Disorders (DSM) classifies nail-biting as
one of the symptoms of obsessive-compulsive disorder. If it becomes
excessive, you should visit your doctor.
7. Bluish Nails
WebMD
explains that when your nails become bluish, it is a sign that the body
may not be getting enough oxygen. Lung problems and heart problems are
among the possible causes.
8. White Spots
Some have mistakenly concluded that white spots on nails mean calcium deficiency, but Dr. Anthony says they are often a result of trauma such as hitting your finger against something.
