Well-groomed hands are extremely important, which is why we so often pay attention to the appearance of nails. Often, however, we do not realize that every bulge, hollow or discoloration can mean something. The nail plate can be a mirror of many diseases. Of course, the changes that occur there are not always dangerous, but it is not worth ignoring them. What do nails say about our health?

Nails and their color

And it's not about a well-chosen nail polish. Unusual discoloration may be a signal that something is happening in our body. Usually, unpainted nails are pink. However, when they turn yellow, it could be a signal that something is happening to our liver, pancreas, kidneys, and even lymph nodes. In turn, pale, almost white plaque may indicate a deficiency of iron or fungi developing in the body. Problems with the respiratory tract are indicated by a blue color around the so-called a cloud, i.e. a white semicircular spot near the skin. However, if the nail is red next to the clouds, it may suggest heart disease. The nail plate can also be brown. Sometimes it is simply the result of a mechanical injury, but this coloration can also indicate problems with the thyroid gland and inadequate nutrition. Not only the color of the tile, but also the skin around it, is important. If it is red, it may be a sign of connective tissue problems.


Coloration should not always worry us. We must bear in mind that the yellow color can be caused by cigarettes or some medications, and even ... nail polishes. Some of them, if we forget about the appropriate base, may discolor our nail. The blue color, in turn, may appear when our hands are cold.

Nail plate - what else can you read from it?

Not only the color is important, we should also pay attention to the shape, texture, spots and direction of the nail growth. Each of these factors can be important.

A problem that affects many people is brittle, splitting nails. What can they testify to? You may have thyroid problems or a deficiency of B vitamins. Brittleness can also be associated with poor stomach function, such as a lack of hydrochloric acid.


Split nails do not have to be a symptom of an illness, but of using the wrong file. Give up the metal one and opt for the glass one - this one will handle the tile best and won't tear it apart.

Some nails also have cracks along the plate which may indicate iron deficiency, or transverse cracks suggest a vitamin B and calcium deficiency. Your nails shine beautifully? While this looks very good, it could be a consequence of thyroid disease. White spots on plaque may be a symptom of an inflammatory disease.

Are your nails concave? This could be a symptom of a hormonal imbalance or anemia. Conversely, a raised plaque may suggest heart defects or problems with blood circulation. If the tip grows upwards, do a blood test, you may be anemic. This direction can also be caused by breathing problems. Conversely, if the toenail grows downwards, you probably lack B vitamins. When your nails also grow sideways, supplement your diet with vitamin C.

If your nails are getting thicker and their color is yellow, and the nail plate is dull, it is possible that you have got mycosis. This cannot be ignored.

The nail plate can be read like a book. It is the source of a lot of information about our health. So let's look at it and see if it changes.Remember that sometimes our plaque has some deviations from the norm and if we have changed "forever", it is not worth panicking when we find out that this may be a symptom of the disease. Let's also pay attention to our general well-being and other symptoms.
