Know our health through the nails

Our nails can be very useful to know how our health is in general , because they show if we are suffering from any disease or if we have some nutritional deficiencies.

The nail is formed by a transparent and bright sheet, also is made up of several parts. The part of the finger that is “stuck” to the nail is known as , and it is quite vascularized. On the other hand, the part closest to the finger, and which has the shape of a half moon with a whiter color, is called a lunula .

The nails grow approximately one to three millimeters every week. In addition, it can present different injuries that can show some health problems. We will talk about these problems below.

The nails are yellow

The nails that show little cuticle, which look very yellowish and also have a convex shape, can be mainly due to the use of enamels that are too pigmented and that have been used for a long time. The snuff can also cause the nails to take a yellowish color, but also another possibility is dryness or simply age.

Similarly, sometimes this color may be related to some problems of the lungs , sulfur .

Currently there are some products that can clean and whiten nails. They are some effervescent tablets that are mixed with a little water and submerged nails to leave them soaking for half an hour, then dry very well and apply a moisturizer. Enamel should be avoided for a few days.


Onycholysis is the separation of the nail from the nail bed. Its cause may be to suffer a trauma or suffer from periungual warts; in many cases, it can also be caused by Hypothyroidism may be another cause of this problem. Sometimes the nail may turn dark brown.

The bites

When the nail grows superficial layers are formed, however when these layers are interrupted irregularities are produced forming certain peaks (very small). This condition can be caused by psoriasis.

Similarly, if a localized dermatitis is presented – whether atopic or chemical – you may suffer from this problem.

The “bulge”

This condition is caused because the tissue on the inside softens, and a curve occurs in the nail, which looks like the shape of a spoon. This may be a signal that indicates a problem in the lungs, inflammation of the colon, cirrhosis, endocarditis or celiac problems.

However, as a curious fact, in the vast majority of cases, people who have these abnormalities in their nails, do not suffer any of the health problems mentioned. It can simply be a direct cause of genetics.

The coilonychia

This is a problem opposite to the previous one, since the nail instead of bulging tends to sink (it passes in any direction), in addition the nails become very soft.

Its cause is directly related to the handling of solvent materials that are derived from oil. Although another reason may be the lack of iron, regardless of whether you have anemia or not, but when this problem happens you must analyze the levels of ferritin.

Beau’s lines

These are depressions that occur throughout the nail, generate several stripes. These stripes can be on all or a few nails.

They are caused by injuries to the nails or by serious problems of malnutrition, lack of calcium or zinc, or simply by problems of diabetes or

In addition, many times it may be because the normal nail growth is interrupted or because chemotherapy treatments have been received.

The muehrcke lines

These are some white lines that are formed transversely. They occur especially when the albumin levels are not at their proper levels, so that, when these levels are controlled, these spots disappear on their own.

As in the previous case, they are usually caused by poor nutrition or by being under chemotherapy treatments.

The leukonychia

This is a problem in which the nail becomes white -either whole or in parts-, white lines or dots can be formed, it can also occur in all the nails at once or only in some.

These are very common spots that can be seen both in adults and children, also have no clinical importance and are temporary problems that can be solved with the consumption of foods rich in zinc.

The scratched nails

The stripes can be vertical and are very common. They are a simple defect of nail growth and do not indicate any health problem, although it is possibly a problem of age.

Being a normal nail aging problem, you should resort to nutrition, which can be achieved by applying enamels based on keratin, which will help the nail to regenerate and grow evenly.

Hemorrhages in the form of splinters

When you have this problem you can see some red lines under the nail , many times they can be signs of endocarditis, important traumas or psoriasis; At other times it is the lack of vitamin C that can cause bleeding.

Color changes

In many opportunities the lunula can change color, it can be blue, but if there are cardiac problems it turns red, and yellow when tetracycline treatments are performed.

When the nails are brown, it can be due to a lot of fluoride consumption , when there is a lack of iron the nail bed becomes very pale, and when there is a problem of cirrhosis the nail can turn white.

Nails to halves

This happens when the nail is put in two colors, in which the distal part of the lunula turns brown.

When there are kidney problems, two colors can often appear on the nails: the part closest to the growth of the nail becomes whiter, leaving the nail of two shades.

Nails tired or unfolded

This is a relatively common problem, and can occur mainly due to dryness, so the solution is to hydrate them very well and very often.

The simplest way to hydrate the nails is to massage them with a cotton soaked in . This should be done several times a day, at night you have to use a good cream and massage your fingers (especially the cuticle).


As you can see, there are many problems that can affect the nails, but each and every one of them has quick and easy solution, you just have to be aware of the changes that occur in them and know how to distinguish the problem in time to find the right solution Remember that every night we must apply a good moisturizer with emphasis on the cuticle area.
