Signs of the appearance of dark lines on the nails

Dark streaks on the nails are a sign of serious health problems, including high cholesterol, according to what was reported by Russian media.

According to data from the American Academy of Dermatology Society, splinter hemorrhage indicates a high level of cholesterol in the blood, which indicates a person's predisposition to developing cardiovascular disease.

The high level of cholesterol in the blood leads to the development of plaques and blockage of blood vessels, which leads to the formation of blood clots, which cause severe consequences and even death.
