May 19, 2023

"As an accessory to the skin, the nails occupy a negligible proportion of the human body, but we should not underestimate the appearance of the nails. A beautiful nail not only adds a lot of charm to a woman, but more importantly, the nail is inextricably linked to our body. So, what is the problem with black vertical lines on the nails?

Caused by liver and kidney dysfunction

If there are toxins deposited in the body and the kidneys are not functioning properly to metabolize the toxins, black vertical stripes will appear on the nails, and the color will gradually deepen, and the same black stripes will appear on other fingers, which may be a reflection of liver and kidney disorders.

Digestive system disorders

If there are black vertical stripes on the nail and the stripes are small and numerous, they may be caused by long-term chronic digestive diseases, such as gastroenteritis, colitis, and stomach disease. If the stripes are deep, there may have been serious gastrointestinal diseases. The darker they are, the more serious they are, and the lighter they are, the more chronic they are.

Caused by nail moles

It is a pigmented nevus that occurs on the nail matrix, and the melanin produced by it advances to the nail edge as the nail plate grows, showing one or more longitudinal brown-black stripes on the nail plate, more common on the thumb. Therefore, it is recommended to go to the hospital for detailed examination and early treatment when the above symptoms appear on the nail.

Trauma

When the nail is traumatized by some external factors, the finger may develop black vertical lines that keep growing slowly, even from the tip of the finger to the end of the finger. The black vertical lines that appear in this case usually fade slowly after a few months, or they may not fade permanently.

Caused by physical fatigue

Sometimes due to overwork or sleep deprivation and prolonged late nights, the body is always in a state of fatigue, the body's toxins will be increased and hosted in the body. The darker the color, the more toxins are present. It is advisable to pay attention to nutrition, ensure sufficient sleep, and pay attention to the combination of work and rest.
