What is nail fungus? How is nail fungus formed?

Don't believe the fools on the above.

Hello buddy, fingernails or toenails turn grayish-white, which people often call " nail fungus ". This is actually a nail disease caused by a fungal infection, which is called onychomycosis in modern medicine. Fungus-caused nail disease can appear in a variety of colors, most commonly grayish-white, but brown, grayish-brown, or dark brown can also be seen.

At the same time, it can be seen that the deck is thickened and brittle, or the middle layer of the deck is hollowed out, or the nail margin is uneven, or the deck is incomplete. Some can also be accompanied by inflammation of the nail groove, local redness, swelling and pain. There are many kinds of fungi that can cause onychomycosis, the most common are Trichophyton rubrum, Trichophyton gypsumiformis, and Epidermophyton flocculus.

Others, such as Trichophyton hyplotsia, Trichophyton purpurea, Trichophyton breakage, Trichophyton rosa and Trichophyton concentric, can also cause onychomycosis. In addition, there are several fungi that often cause nail lesions in the case of nail dystrophy, such as Candida albicans, Aspergillus flavus, Aspergillus fumigatus, etc. We know that nails or toenails are very hard, and an intact deck is completely resistant to any microbial attack.

But why do so many people get onychomycosis? Onychomycosis patients often suffer from ringworm of the hand or athlete's foot first, and the fungus first invades around the nail and then gradually invades the nail plate through the growth and evolution of the nail or toenail and further grows and multiplies until the entire nail plate is destroyed. If the fungus invades the root of the nail and affects the growth of the nail, it can cause nail dysplasia or nail deformity.

In general, this process is relatively slow, but more often onychomycosis occurs due to fungal infection after the nail is broken due to trauma or frequent scratching. For example, patients with athlete's foot or jock itch often scratch their fingernails because of the unbearable itching, so that the fingernails can be stained with many of the fungi in the lesions. Long-term repeated scratching and rubbing, nails are easily damaged, so that the fungus can take advantage of the weakness to cause nail disease.

In addition, there is also a condition that is prone to onychomycosis, that is, when the systemic or local resistance is low. The former mainly refers to people with congenital immune deficiency and special susceptibility to fungi; The latter is seen in patients with nail dystrophy or nail dysplasia. It is important to note that there are many causes of nail changes, and nail disease cannot be considered to be onychomycosis.

We will not go into the details here, but it is important to understand that the onset of onychomycosis often starts with one nail and gradually spreads to other nails. If ten fingernails or toenails occur at the same time, it is often a manifestation of a systemic disorder. Of course, the most fundamental evidence to confirm the diagnosis of onychomycosis is a fungal examination, that is, scraping a small amount of debris from the diseased nail, or examining it directly under a microscope, or cultivating it on a culture medium, as long as the disease-causing fungus can be found, no further explanation is required.

With the development of society, the incidence of nail fungus is getting higher and higher, and more and more people are suffering from nail fungus, because of the great impact of nail fungus on appearance, so that everyone does not want to suffer from nail fungus, so many friends want to know what nail fungus is, the following is what I have to sort out the causes of nail fungus for you, I hope you like the article!

Infectiousness:

Nail fungus can not only spread more on one's own nails, but it can also cause other diseases in the body. In particular, nail fungus is most likely to occur if there is nail trauma and if the immune system is weakened. Therefore, it is necessary to pay attention to external infections to avoid the occurrence of nail fungus.

There is a physical illness:

People with physical diseases, especially those with high blood sugar, can easily induce the occurrence of nail fungus. If there is a disease, the body's resistance will decrease, the immunity to the disease will naturally decrease, and the ability of the nails to resist fungi will be reduced, which can easily lead to the occurrence of nail fungus.

Regional differences:

The survey found that the incidence of nail fungus in my south is much higher than that in the north, which is mainly related to the difference in humidity and temperature in the region, and it is not excluded that work pressure, mental stress and other reasons lead to the occurrence of nail fungus in the summer.

Nail fungus infection is caused by microorganisms of pathogenic fungi, mostly caused by the spread of athlete's foot. In recent years, the incidence of nail fungus is getting higher and higher, but often many people do not pay attention to nail fungus, thinking that nail fungus is not harmful to the human body, so what are the reasons for the formation of nail fungus? Here's the answer.

1. Trauma and barbs are also the causes of nail fungus, and about half of the patients have a history of trauma;

2. People suffering from tinea capitis and tinea pedisa, when scratching hair with their hands or touching ringworm, the fungus takes the opportunity to invade the deck;

3. Paronychia is also the cause of nail fungus, because the nail edge is cut too short or too deep, which makes the nail groove wall macerated and sweaty;

4. Pregnant women are also prone to nail infection. Women will have endocrine disorders during pregnancy, which will reduce the ability to resist fungi, and nail dystrophy will cause fungus to multiply, which will cause nail infection;

5. Nail fungus often develops from the free edge or lateral edge of the nail (toe) to the nail root, the diseased nail gradually loses its luster, becomes dull and turbid, gray-white or brown, and gradually thickens and becomes brittle, uneven or deformed, easy to break due to brittleness, or the cuticle gradually softens into powder, forming a niche on the deck, the edge of the nail is uneven, there are defects such as insect bites, and in severe cases, part of the deck is separated from the nail bed, which affects the appearance and hygiene.

Nail fungus is a highly contagious disease. In life, nail fungus often suffers from contact with people with nail fungus, poor resistance, frequent nail articures, nail breakage and fungus infection. Patients should pay attention to the identification of nail fungus to avoid suffering from this disease.

In daily care, it is necessary to pay attention to the following:

Sharing baths, footbasins, towels or slippers with others, etc., in family or group life, and entering public baths, swimming pools, saunas, dance halls, etc., can lead to transmission.

Feet should be washed and socks should be changed every day, shoes and socks should be exposed to the sun, and keep hands and feet dry and cool, bedding and sheets should also be dried often to kill germs and reduce the chance of infection.

Wearing small-sized shoes regularly will increase the chance of nail fungus infection, because small-sized shoes are not breathable, and the five fingers squeeze each other, which can easily cause the nail bed and finger flesh to peel off. When the health of the nails is affected, the chances of contracting nail fungus are greatly increased.

When the body's resistance decreases and the fungus is damaged, it will cause the fungus to invade, and they will take advantage of the weakness to cause disease.
