How is the thumb nail blackened?

Some substances in toenails are related to the onset of cardiovascular diseases. Compared with fingernails, toenails grow slowly and some are more stable, which can be used as a measurement method. The growth rate of toenails is influenced by health, season and exercise. People with slow toenails may not exercise much, and some trace elements in their bodies may be insufficient, so the risk of cardiovascular disease may be higher.

What is a healthy toenail? Specialist experts pointed out that toenails are light pink in color, with natural luster, and should be smooth and bright. There are no vertical and horizontal grooves on the nail surface, no interference spots on the nail, and the nail is symmetrical, offset, concave or upturned at both ends. If the nail is deformed or discolored, it means that the nail is not normal, and it also replaces the already sick body.

The main reason for the blackening of toenails may be onychomycosis. At present, nearly 80% of most patients have onychomycosis. Onychomycosis usually starts from 1-2 nails, and can involve all nails in severe cases. The sick deck loses its luster, and sometimes the deck is separated from the nail bed. The deck is often uneven and dark black, often slightly atrophied without thickening, often accompanied by paronychia.
