WHAT FINGERNAIL ABNORMALITIES SAY ABOUT YOUR HEALTH

WHAT FINGERNAIL ABNORMALITIES SAY ABOUT YOUR HEALTH

Did you know that your fingernails can provide clues to your overall health? Normal, healthy nails should appear smooth and have consistent coloring, but as you age, you may develop vertical ridges, or your nails may be a bit more brittle. This is harmless and nothing to worry about. If you notice spots due to injury on your nails, this should grow out with the nail and not turn into a big deal.

Abnormalities that occur on the nails may warrant a closer look. These oddities such as spots, discoloration, and nail separation can be the telltale sign of viral warts, infections, and some medications, such as those used for chemotherapy.

 

White Nails

 

If the nails are mostly white with darker rims, this can indicate liver problems, such as hepatitis. In the image below, you can see the fingers also appear yellowish in color meaning they are jaundiced, which is another sign of liver trouble.  Very pale nails can sometimes be a sign of other serious illnesses, such as: Anemia ,Congestive heart failure, Liver disease, Malnutrition

White Dots

If small white dots that appear on the surface of the nail that won't budge when you try to buff them off, this is usually due to some type of trauma—even something as simple as a banged finger or a too-aggressive cuticle trim. In this case, give them some time to grow out and fade, but if they don't go away, see your dermatologist, as it could be the signs of other health issues such as Leukonychia.

Leukonychia

Commonly called white nails or milk spots, and is more frequently located on fingernails compared to toenails and often can be found in the central portion of the nail plate. The normal nail beds needs to be pink in color showing good blood flow underneath the nail plate.

These white spots usually are completely benign, although in some other situations it could be an indication of an underlying disease. Bacterial or perhaps fungal infection on the nails could potentially cause, or an unusual side effect of systemic chemotherapy. This can be found in people with arsenic poisoning, kidney failure, respiratory condition. Contact with extreme cold could possibly result in progression of leukonychia, but these spots will slowly vanish over time.

Yellow Nails Syndrome

With yellow nail syndrome, nails thicken and new growth slows. This results in a yellowish discoloration of the 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, crumble, lack a cuticle and detach from the nail bed in places. Yellow nail syndrome is often a sign of respiratory disease, such as chronic bronchitis. Yellow nail syndrome can also be related to swelling of the hands (lymphedema). In rare cases, yellow nails can indicate a more serious condition such as severe thyroid disease, lung disease, diabetes or psoriasis

Bluish Nails

The medical term of Blue fingernails is cyanosis, and can be a sign of various disorders so it should be checked out. While very cold temperatures can temporarily slow the flow of blood through the skin leading to a bluish color, this should go away once you warm up. In Raynaud's disease the fingers and toes blanch, then turn blue and may become numb or painful when exposed to cold. The problem is simply over-sensitivity of nerves controlling blood flow through small arteries in the fingers, toes, nose and earlobes.

This odd coloration can also be due to low hemoglobin, which carries the oxygen in red blood cells. Normally, blood is bright red due to the oxygen it contains, but when oxygen levels decline, blood turns a blue-red color.

This chronic cyanosis can be a sign of many different lung and breathing issues like asthma, emphysema, chronic obstructive pulmonary disease, chronic bronchitis and other respiratory disorders. It also can be a sign of a number of heart problems, a response to high altitude or an overdose of certain drugs such as narcotics, benzodiazepines, and some sedatives.

Green Nails

Green nails are the result of a pseudomonal infection, which is usually caused by the environment. This means that those who's immune system is already low are very susceptible to this type of nail infection which makes the nail often appears green in color.

Nail Pitting

Small hole or ice pick-like depressions in the nails (nail pitting) are common in people who have psoriasis, which is a condition characterized by scaly patches on the skin. Nail pitting can also be related to connective tissue disorders, such as Reiter's syndrome, and alopecia areata — an autoimmune disease that causes hair loss.

Rippled Nails

If the nail surface is rippled a lot like the pitting I discussed above, and this may also be an early sign of psoriasis or inflammatory arthritis. Discoloration of the nail is also common, as the skin under the nail can seem reddish-brown.

 

Cracked or Split Nails

Cracked or split nail is one of the common yet disease related nail disorders. 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. Low levels of Vitamin C, folic acid, and certain proteins in the diet are also known to cause nail splitting.

 Nail Ridges

These can either be horizontal or vertical. With vertical nail ridges, this can signify nutrition issues, moisture loss or nutritional absorption issues. Horizontal ridges in the nail are often associated with diabetes, liver diseases or other chronic diseases. Either type of ridges can also be caused by damage to the nails.

Dark Lines Beneath the Nail

If you have dark skin, it's fairly common to have streaks of the pigment melanin down your fingernails. However, you should still get this checked by a doctor, as it may occasionally indicate a form of skin cancer called subungual melanoma, the most dangerous type of skin cancer. Generally this only affects one nail, causing the stripe to change in appearance, and becoming wider or darker over time. The pigmentation may also affect the surrounding skin.

Little Brown Streaks

These are thin dark lines under the fingernail that could be from mean tiny vessels under the nail that are bleeding. These are known as "splinter hemorrhages," and are nothing to worry about if they are due to the nail being injured. However, if a few nails are affected, this may be a sign that one of the heart valves is infected, known as "endocarditis". Splinter haemorrhages can also be associated with several other conditions, such as scleroderma, lupus, psoriasis and rheumatoid arthritis.

Nail Beading or Vertical Ridging

This appears as vertical beaded ridges resembling a candle's wax drippings. With nail beading, the beads seem to drip down the nail like wax, and it is associated with endocrine conditions, like diabetes mellitus, thyroid disorders, Addison's disease, Vitamin B deficiency, hormonal changes, or stress.

 Nail Clubbing

Clubbing of the fingertips can run in families and could be harmless. However, if it suddenly develops, it may be a sign of an underlying medical condition, and due to low oxygen levels in the blood, resulting in various diseases such as lung or heart disease.

With clubbed fingertips, this natural angle is gone and the nails are in line with the top of the fingers. Hamman-Rich syndrome, or acute interstitial pneumonitis, (a form of pneumonia) characterized by inflammation of the lung. With advanced interstitial lung diseases, digital clubbing and signs of heart failure may appear. It is also associated with inflammatory bowel disease, cardiovascular disease, liver disease and AIDS.

Terry's Nails

This was named for Dr. Richard Terry and is when the fingernails and/or toenails appear white with a characteristic "ground glass" appearance, with nolunula, or the white crescent-shaped area of a finger nail. With the condition known as Terry's nails, most of the nails appear white except for a narrow pink band at the tip. It is described as a brown arc near the ends of the nails.

Terry's nails can sometimes be attributed to aging. In other cases, Terry's nails can be a sign of a serious underlying condition. This condition could be due to a decrease in vascularity and an increase in connective tissue within the nail bed, and frequently occurs in the setting of liver failure, cirrhosis, kidney failure, diabetes mellitus, congestive heart failure, hyperthyroidism, and/or malnutrition.

Onychorrhexis

This is the presence of longitudinal striations or ridges on the nail plate, can simply be a sign of advanced age, but it may also be associated with conditions such as rheumatoid arthritis, peripheral vascular disease, lichen planus, and Darier disease (broad white and red striations in the nails). A central vertical ridge or groove (shown) may be due to myxoid cysts that appear near the nail fold, which are associated with osteoarthritis.
