What cause the vertical lines on a persons fingernails? What deficiency in the body cause this?

Answer 1

This online medical encyclopedia lists a number of other causes of
nail abnormalities. These abnormalities may include vertical or
transverse ridging, in addition to several others.

-A crush injury to the nail bed may lead to irreversible vertical or
horizontal ridging depending on the extent of the injury.

-Infection of the nail bed (fungal, bacterial, viral) can lead to
varied ridging, which is usually associated with a change in nail
color as well.

-Viral warts, when in or near the nail bed, can put pressure on the
nail plate and cause ridging in a line tracing back to the wart
itself.

-Disorders leading to reduced oxygen levels in the blood (abnormal
heart anatomy, chronic lung diseases) can lead to “clubbing”, or a
rounded appearance similar to back of a teaspoon. This type of nail
abnormality warrants notifying your personal physician.

-Kidney disease, leading to an excess of nitrogen waste, can cause
nail abnormalities.

-Liver disease, including chronic liver failure, can also cause nail abnormalities.

-Hyper- or hypothyroidism often leads to brittle nails, or possibly a
separation of the nail bed from the nail plate (“onycholysis”).

-Infection (usually of one of the heart valves) may lead to “splinter
hemorrhages,” which are red streaks visible beneath the nail plate.
The presence of such streaking is a medical urgency and should be
reported immediately to your personal physician.

-Amyloidosis, a systemic connective tissue disease, can cause varied
abnormalities of the nail.

-Severe illness/stress can lead to a complete cessation of nail growth
during the time of stress. This results in a deep depression, or
complete absence of the nail, known as “Beau’s lines.”

-Vitamin deficiency/malnutrition can lead to brittle nails, or a
change in the appearance of the nails, depending on the specific
nutrient that is deficient. Iron deficiency is a common cause of nail
abnormalities, usually presenting as a depressed nail with elevated
ridges toward the outside of the nail.

-Psoriasis can lead to “pitting” (or depression) of the nail,
onycholysis, or nail dystrophy (misshapen nails). Psoriasis rarely
exhibits nail findings alone, however, and is usually associated with
flaking of the scalp, or silvery, dry patches on the elbows, knees,
etc.

-Arsenic poisoning, while rare today, can manifest itself as white
lines and horizontal ridges on the nail.

-Silver, usually taken as a colloidal supplement, can lead to argyria,
or an irreversible blue hue of the skin, secondary to deposition of
the metal within the skin. This color change is also present beneath
the nail plate.

To summarize, vertical ridges usually represent a normal aging
pattern, and some consider the presence of such ridges to be an
indicator of those at risk for developing arthritis. At any rate,
vertical ridges can be considered “normal” and medically
insignificant.

Transverse, or horizontal, ridges, however, usually represent an
underlying pathological process—trauma, vitamin deficiency, chronic
illness, etc. The presence of nail ridges, along with any symptoms of
illness should be discussed with your personal physician to determine
an underlying cause.
