Check your nails: 7 signs that may indicate potential health issues.

According to dermatologist Julia Tsi from a medical center in New York, discoloration or paleness of the nails that was not previously observed may indicate issues with the nail plate.

“If such spots appear, they may serve as early signs of developing melanoma of the nail plate,” explains the doctor.

“If the nails have taken on a yellowish tint, this may indicate the presence of psoriasis,” notes the physician. Additionally, according to several specialists, yellow nails can signal emerging liver problems.

This signal is equally concerning — the appearance of a bluish tint (cyanosis). According to Dr. Andrea Weil from Harvard Medical School, this may indicate low hemoglobin levels, circulation issues, and respiratory problems.

They may appear and disappear. Many choose to ignore this. However, that is a mistake. Small white spots of various shapes indicate a deficiency of zinc or calcium in the body.

If horizontal white lines start to appear on the nails, this indicates a kidney disease, warns Julia Tsi. This condition has a specific name — leukonychia.

According to the doctor, the presence of small indentations on the nail surface may indicate that a person is constantly experiencing significant stress. The second reason could be a metabolic disorder. Finally, the third reason could be a nail injury.

Thin longitudinal lines on the nails are most commonly seen in elderly individuals, as this phenomenon is due to age-related changes in the body. However, sometimes stripes can also appear in younger people. In this case, the emergence of longitudinal lines may indicate that the individual is not consuming enough fluids.

There are several reasons for this. Among the most common, doctors note deficiencies in vitamins A, E, D, as well as iron and zinc. Furthermore, brittle and splitting nails may indicate problems in the endocrine and cardiovascular systems and could, in particular, be an early warning sign of diabetes.
