How to determine the presence of serious diseases in a person by their nails?

Any changes in the color and condition of nails can indicate hidden serious problems in the body.

Dermatologist Andrey Malvestiti told about this in an interview with Veja.

According to him, white spots on nails are a harmless phenomenon, and purple spots can be ordinary bruises from injuries. However, if you notice black, gray, or brown spots, don't delay visiting a doctor - such changes may be a symptom of melanoma, a dangerous form of skin cancer.

If the nail begins to peel off, this may indicate an infection or an allergic reaction to household chemicals. And the appearance of warts near the nails is often associated with the human papillomavirus.

The doctor also noted that most often patients complain about thickening and brittleness of nails. This may be related to age-related changes, as nails age just like skin. However, deterioration of their condition can also be caused by more serious diseases - such as diabetes, iron deficiency anemia, thyroid problems, arterial diseases, psoriasis, or atopic dermatitis.
