Dark lines under the nails, reminiscent of small splinters, may indicate an increased level of “bad” cholesterol in the body, and this is fraught with the appearance of diseases of the cardiovascular system.
Writes about this British edition Expressciting data from the American Academy of Dermatology (AAD). Such stripes under the nails are nothing more than minor bleeding due to vascular damage. It is believed that one of the most common causes of this is high levels of “bad” LDL (low density lipoprotein) cholesterol. It deposits on the walls of blood vessels, forming plaques and interfering with blood flow.
High levels of such cholesterol are commonly referred to as the “silent killer” because they are usually not accompanied by overt symptoms. The condition of the nails can be one of the warning signs, but in this case, you can get more accurate information only with the help of a blood test.
You can bring cholesterol levels back to normal through diet, reducing the consumption of animal fats and sugar, and exercising regularly.
