First and foremost, spotting melanonychia is often a sign of healthy nail growth. These spots generally signal that the nail cells are receiving sufficient amount of both blood supply and melanin—a natural pigmentation that determines one's skin color. Melanin protects the nail cells from extreme temperatures, ultraviolet radiation, and other environmental influences.
Another benefit of the spots is that they can help detect possible skin issues such as psoriasis, lichen planus, and dermatomycosis. Psoriasis is a non-infectious skin disease characterized by itchy, scaly, and red patches; as for lichen planus, it's a common skin condition caused by the body's overactive immune system. Dermatomycosis, on the other hand, is caused by fungal infections. When it comes to these common skin problems, black spots under the nail can be a telltale sign. If you notice dark spots and other associated symptoms, don't hesitate to visit your doctor.
What's more, melanonychia can also be evidence of vitamin or mineral deficiencies such as iron, copper, vitamin C, folate, and B12. These deficiencies can lead to symptoms such as fatigue, anemia, or paleness. If left untreated, these conditions can worsen and lead to a range of other serious complications. A wide range of foods, from dark green leafy vegetables to garlic, provide reliable amounts of nutrients and vitamins; making sure that you consume all the required minerals can also help prevent any associated problems.
As a final point, bear in mind that certain medical treatments or other factors can also be responsible for dark spots. If you rarely wear gloves while gardening, for example, you may notice some spots due to the scratches on the nail.
In conclusion, black spots under the finger or toe nails aren't always a cause for alarm. They can actually be an indication of healthy nail growth, a signal to detect common skin issues, and a way to tell if you’re not getting enough vitamins and minerals. If the spots are accompanied by other symptoms or persist for a long time, make sure to consult a doctor.
