White spots on nails: why they appear, what they mean, how to remove them

White spots on the fingernails, medically called leukonychia, are pathological changes in the nail plate.

What do white spots on nails mean? A characteristic feature of leukonychia is white spots on the nail plate in the form of dots, stripes or large areas of various shapes, sizes and locations.

Leukonychia is widespread, but not many take the disease seriously, considering the problem to be purely cosmetic. Somatic and infectious diseases may be behind the white spots on the fingernails, so the symptom should not be ignored.

Why do white spots appear on the nails? This question is often asked by women who are more susceptible to this symptom. White spots on the nail plate of a child with an 80% probability indicate hypovitaminosis, the remaining 20% are occupied by “rodents” of the nails.

General information

White spots on the nail plates appear in many people at a certain period of life. Most often they are perceived as a kind of cosmetic defect. But in fact, white spots on the nails indicate that not everything is in order in the human body. This is leukonychia - a phenomenon when, due to various reasons, white lines and spots appear on the nail plate as it grows. Leukonychia can be associated with a number of diseases, as well as with a lack of substances important for the body, and even with certain habits. But in any case, it is worth determining the cause of such a symptom and, if possible, eliminating it.

A little anatomy

Initially, you should familiarize yourself with the anatomical structure of the nail. This will help you understand what the spots mean and why they are formed.

The body is the visible part of the plate. Normally it should be shiny, nasty and durable, but at the same time elastic. The body is constantly growing, but only at the upper edge; the sides rest against the skin ridges, limiting growth in width. The body has a layered structure, so it can flake off.
Root - this part is located at the cuticle (in other words, a white stripe or hole that is visible in many people). It consists of cells - onychoblasts, which quickly divide and are responsible for growth.

The composition of the marigold consists mainly of keratin protein, then water and a little fat, which gives a healthy shine.

Pathogenesis

Pathological changes on the nail plates (on one or several at once) occur due to disturbances in the process of keratinization of the nail. Due to the influence of various factors, the functions of the nail matrix, which determines the formation of the plate and its growth, may fail. Such disorders lead to incomplete maturation of the cells of the nail plate, deterioration or absence of their keratinization. As a result, a layer of air appears in the thickness of the plate, which is then filled with fat and water. Such layers look like white spots on the nail.

Detachments

If the nail begins to lift and curve so that it is no longer fully attached to the nail plate, you will see a discoloration to white or a yellowish milky color.
When the nail is raised, the cause is often a fungal infection, exacerbation or progression of psoriasis, trauma from aggressive manicure, or cleaning the space under the nails with a sharp object. A dermatologist should examine any nail that is raised at one or both edges. You may need treatment to clear up the fungal infection. The dermatologist can also give some tips to help with subsequent normal growth.

Classification

There are several varieties of this pathology:

Limited leukonychia - in this case, partial damage to the plate is noted.
Stripe leukonychia - with this form, whitish stripes, vertical or horizontal, appear on the nail plates. Often a similar symptom appears if poisoning with thallium or arsenic has occurred.
Point leukonychia - this variety is characterized by the appearance of white dots. They can be small or large, single or multiple. This form is the most common today. It usually develops after various mechanical damages.
Total leukonychia - the entire plate is completely affected. The pathological process begins in the nail hole. Most often, such a lesion occurs in childhood or adolescence. It is associated with past infections, fungal diseases, liver and kidney diseases.

According to the size of the spots, the following forms of damage are determined:

Subtotal (limited) - appear if keratinization of the plate appears partially and does not occupy the entire surface. Typically, several nails are affected.
Total – lesions are located over the entire surface and can appear on all nails at once.

Thick, claw-shaped nails

Sometimes the nails become similar to the beak or claws of birds; they thicken, sag, and may change color.
This occurs when growth is disrupted and cells divide randomly. Some people have a hereditary predisposition to this form, but then close relatives should have the same. Most often, such deformities are provoked by psoriasis, ichthyosis or circulatory problems. If a person has problems with the heart or lungs (for example, chronic hypoxia), nails can also change in thickness and shape.

Causes

There are many factors that should be listed when answering the question of why white spots appear on nails. The cause of the appearance of white spots may be due to either injury to the plate or exposure to chemicals. In addition, there may be other reasons for white spots on the fingernails. So, sometimes leukonychia is congenital.

If we consider the reasons why white spots appear on fingernails, we should distinguish between external and internal causes.

External reasons may be the following:

Injuries, bruises, compression of the plate. In this case, the marks appear on one or more nails, such as the thumbnail.
Violation of manicure technique, leading to injuries.
Carrying out a manicure using products hazardous to health. Sometimes specialists use very aggressive means that speed up the process, but at the same time have a negative effect on the body. Stains may appear after shellac, gel, etc.
Using chemicals to remove nail polish. You need to buy only products from trusted companies.
Contact with chemicals that are harsh on hands. All housework should be done wearing protective gloves.
Work involving constant contact with chemicals (construction mixtures, etc.).
Wearing shoes that are too tight may be the cause of white spots on your toenails.

Internal reasons:

Very strict diets, unhealthy and monotonous nutrition.
Bulimia , anorexia .
Diseases of the digestive system, ulcers, ulcerative colitis , hepatitis, etc.
Pyelonephritis.
Deficiency of substances important for the body - minerals, vitamins, in particular iron, vitamins A and B6 .
Long-term depression.
Chronic stress, constant uneven overexertion.
Diseases of the heart and circulatory system.
Fungal infections - because of them, spots can appear on the nails of the toes and fingers.
Metabolic disease.
Psoriasis.
Intestinal dysbiosis.
Some infectious diseases.

If a person goes to the doctor to find out why white spots appear under the nails, after examination it may turn out that this phenomenon is associated with several reasons at once.

It is important to take into account that white spots on the nails of the toes and fingers can also appear due to the presence of certain bad habits:

The habit of cutting your nails too short.
Biting cuticles or nails.
The need to frequently type on the keyboard.
Frequent manicure with aggressive agents and lack of “rest” for nails.
The habit of drumming on the table with your nails.

It is interesting that in connection with the appearance of such marks, there are even folk signs, and people who take superstitions seriously are interested in what the white spots on the fingernails mean. It is believed that, for example, white spots on the thumb promise an upcoming big purchase, on the index finger they mean sad events, and on the middle finger they mean good luck. On the ring finger, such marks supposedly appear as a sign of discord, and on the little finger, as a sign of joy. However, to seriously believe that the white spots on the nails mean exactly what the signs say is, at a minimum, illogical and irresponsible. After all, all that such symptoms indicate is health problems that need to be detected and eliminated.

When it's about fungi

This is one of the most common diseases affecting nails. In half the cases, dermatologists diagnose fungus when people come to them complaining of nail damage.

Onychomycosis is caused by different types of microorganisms: dermatophytes, yeasts or molds. The pathology is considered infectious and contagious. It is easy to pick up in a public place with high humidity levels (swimming pool, sauna). Symptoms of onychomycosis include:

change in color of the plate, it may turn yellow or black, in some cases white spots appear;
the nail becomes thick and at the same time brittle;
the plate delaminates, growing a little it easily breaks off;
shine and gloss disappear, the nail becomes dull;
Detachment and destruction of the affected plates is possible.

Fungal infection goes through four stages of development; if you start treatment at the initial stage, it will be simple and short-lived.

Symptoms

If white spots appear on the nails of an adult or child, their severity and type depend on the cause that provoked the disruption of the keratinization process. Sometimes, by analyzing the characteristics of this symptom, the doctor can determine why there are white spots on the nails of an adult or a small patient.

Nail injury in adults and children. Dotted marks appear, less often - stripes. They are located in those places that have been injured. The defeat is limited.
Lack of nutrients due to strict diets and poor nutrition. Stripe-shaped paired leukonychia appear, located horizontally.
Hypovitaminosis. Single leukonychia appear. If the state of hypovitaminosis persists for a long time, marks may appear on several nails. In this case, there is general weakness, hyperkeratosis , dry skin, and a feeling of fatigue after habitual exercise.
Gastrointestinal diseases. Total leukonychia is noted, both on the arms and legs. Signs of the underlying disease are noted.
Heart failure. Multiple or single lesions, cyanosis of the plates.
Chronic stress, depression, nervous exhaustion. A large white spot in the center of the plate, which disappears after it grows back.
Fungal infection. The lesion occupies a limited area. The nail becomes yellow, it becomes exfoliated and softens, its tissue thickens, and an unpleasant odor appears. If the disease progresses, the lesion covers other fingers.

Color Changes

Diseases inside the body cause the nails to change color. Certain color characteristics can be a warning sign of a certain disease.

Blue
- not enough oxygen in the blood.
White
– liver disease and diabetes.
Pale

Half pink, half white
- kidney disease.
Yellow

Analysis of scrapings to determine fungal infection.
Spectral analysis of the plate for the determination of microelements.
General and biochemical blood tests to determine the presence of pathological processes in the body.

Based on the data obtained, the doctor prescribes other studies or consultation with specialists.

It is important to carry out differential diagnosis with the following diseases:

Onychomycosis - develops when infected with a fungal infection.
May's stripes are a symptom indicating thallium or arsenic poisoning.
Brittleness and delamination are a consequence of the dryness of the plate.
Violation of shape - the nail may grow in and have a pathological shape.

Before starting treatment, doctors conduct a comprehensive check, find out what the spots mean and what caused them. It is necessary to take a blood and urine test and scraping from the affected nails.

In mild cases, it is necessary to normalize the diet and adhere to a healthy lifestyle. If the situation is advanced, you will have to take medications, a vitamin-mineral complex (first find out which vitamins are missing).

In childhood

From time to time, parents notice whitish specks on the nail beds of their offspring. What do these formations mean? The reasons for the appearance of pathology in children are similar to rashes on the plate in adults. In addition to those listed above, these include: hormonal imbalances, allergies, the appearance of worms, metabolic disorders, problems with the respiratory tract.

The course of treatment for a child mainly consists of changing lifestyle, that is, restructuring the daily routine and updating the diet. “If there is a lack of vitamins and minerals, pediatricians advise consuming more milk, fresh vegetables and fruits, wheat germ cereals with the addition of nuts.”

If an allergy to certain foods is detected, antigens that contribute to the appearance of dots are completely excluded from the baby’s menu. Worms are eliminated with the help of careful hygiene before eating and local medications - Pirantel, Piperazine. For fungus, ointments and creams are prescribed: Clotrimazole, Pimafucin.

Popular beliefs

Whitish markings have long been considered a good sign. By the number of formations and shape, as well as location, they learned what would happen in the near future. But what do the beliefs say?

When a dot appears on the middle finger, it means purchasing new clothes or beautiful things for the home. If the owner managed to immediately cut off the inclusion, then in the near future he would expect great profits and material well-being.

Now the belief has a different character. The mark appears on the nail before going to the store - this means a successful purchase. And when it comes to wardrobe items, they last longer. For a sick person, signs promised a speedy recovery.

The inclusions on the ring fingers predicted mutual love, prosperity and family happiness in the future. Small-sized formations promised good news. If longitudinal whitish stripes appear on the thumbs, it means that you will soon be promoted, your salary will increase, or success will await you in all matters.

In children

Parents often notice that white spots have appeared on their child’s nails. If we are talking about a single spot that moves forward as the nail grows, then most likely it is caused by injury, and you should not worry about it.

To understand why your child has large numbers of white spots on his nails, you should visit a dermatologist with him. In a child, such signs may be associated with the following reasons:

Deficiency of calcium and other trace elements or vitamins. In this case, as a rule, other signs are also expressed. A baby with this problem has dry hair and skin, he may often catch colds, etc. In this case, the doctor will recommend making adjustments to the daily diet or prescribing appropriate medications. If there is a zinc deficiency, a child may develop longitudinal white stripes. A lack of zinc can be associated with chronic stress, pesticide poisoning, as well as a calcium deficiency, which promotes the absorption of zinc. It is also important to avoid a lack of B vitamins, as well as A, C, E.
Lack of protein. Since the basis of the nail is the protein keratin , a sufficient amount of protein is required for normal formation of the plate. In this case, it is very important to adjust your diet.
Anemia associated with iron deficiency. If the hemoglobin is too low, oxygen starvation occurs, leading to unpleasant symptoms. A baby with anemia has pale skin, gets tired quickly and complains of weakness. In this case, more iron-containing foods are introduced into the menu and appropriate medications are prescribed.

In any case, a doctor will help determine the cause. Parents should not hesitate to contact a specialist.
