(1) What is the reason for black vertical lines on nails?

Some people's nails have a rough surface, and if you look closely, you can see vertical lines. If this situation appears for a short time and disappears quickly, it is usually due to excessive brain use and overwork; if the vertical lines persist, it may be a chronic disease of the organs in the body. The first is malnutrition, which may be caused by calcium deficiency and decreased immunity of the body. If there are black vertical lines on the nails, it means that the liver and kidney functions are relatively weak.

Also note that the depth of the finger lines is related to the severity of the disease.

There are also horizontal lines. When they first appear, they may start from the bottom of the nail. As the nail grows, they gradually move upward. In this case, the horizontal lines on the nails are a record of the lesions that have occurred. If the horizontal lines are small and numerous, it indicates long-term chronic digestive system diseases, such as gastroenteritis, colitis, stomach disease, etc. If there is a very deep horizontal line, it means that you have had a serious gastrointestinal disease. The deeper it is, the more serious it is; the shallower it is, the more chronic it is. If the horizontal lines are raised, it indicates heart problems, liver problems, and a lack of vitamin A, B, etc.
