Causes of black toenails

The blackening of toenails may be caused by blood stasis in our toenails, or it may be caused by onychomycosis, so we recommend that the blackening of toenails be analyzed so that we can use the correct method to treat it. If the toenails turn black due to blood stasis caused by the toenails being pressed down, they will generally recover in a few days, so you don't need to worry too much.

The content of some substances in toenails is related to the incidence of cardiovascular diseases. Toenails grow more slowly than fingernails, and some of the substances in them are more stable, which can be used as a measurement method. The growth rate of toenails is affected by health, season and exercise. People whose toenails grow slower may be less fond of exercise and may also lack some trace elements in their bodies, so they may be at higher risk of cardiovascular disease.

Specialists point out that healthy toenails should be light pink in color and have a natural luster. They should be smooth and shiny, with no vertical or horizontal grooves on the nail surface, no interference spots on the nail, and the nail should be symmetrical, not skewed, without depressions or upward curling at the ends. If the nails are deformed or discolored, it means that there is something wrong with the nails, and it also means that the body is sick.

The main reason for toenails to turn black is most likely onychomycosis. Among most of the patients currently seeking treatment, nearly 80% suffer from onychomycosis. Onychomycosis usually starts with 1-2 nails, and in severe cases all nails may be affected. The diseased nail plate loses its luster and sometimes separates from the nail bed. The nail plate is usually uneven and dark in color. The nail plate is often slightly atrophied but not thickened, and is often accompanied by paronychia.

Black toenails: more common in people with severe heart disease, tumors or long-term medication.

Pink toenails: It may be due to decreased organ function and excessive physical exertion, which may easily cause diabetes, hyperthyroidism and other diseases.

Purple toenails: can easily cause poor cardiovascular blood circulation, insufficient blood supply and oxygen supply, and can easily lead to dizziness, headaches, and arteriosclerosis.

Gray toenails: may indicate low energy, which may easily lead to anemia, fatigue, and weakness.

The article introduces to us in detail the reasons why toenails turn black. I hope you can understand it better in your life. If your toenails turn black due to onychomycosis, we recommend that patients should properly remove the onychomycosis so as not to affect the normal condition of other nails.
