Fingernails can reveal a lot about the state of the body, acting as a kind of health indicator. They not only reflect a person's age and lifestyle but also signal internal problems that a person may not even be aware of.

Nail color plays a key role in diagnosis. Purple fingertips may indicate digestive problems, while a dark red hue with a violet tint signals possible kidney problems. Skin spots near the Mounts of Venus may indicate reproductive system problems, and red nodules between the fingers are often associated with the thyroid gland. Rough skin on the back of the index fingers may indicate gallbladder problems.

Besides color, the shape and texture of the nails are also important. A bluish or pale tint to the nails may indicate circulatory problems. Transverse grooves in nails appear after infectious diseases, while longitudinal scars often indicate an unbalanced diet. Horizontal dents or pits arise from an improper diet or nutritional deficiencies.

Brittle nails are a common problem that can be caused not only by harsh chemicals but also by metabolic disorders or gynecological issues, including ovarian dysfunction. White spots on nails may indicate excess sugar in the blood, while yellow spots may indicate lipid metabolism disorders or respiratory diseases.

Concave nails often indicate anemia caused by iron deficiency, while whitish or pearly lunulae appear due to poor nutrition of the skin. Nails can also be used to determine when a problem arose: nails grow approximately 1 mm per week, and a complete nail cycle takes about six months. Therefore, problems that appear on the nails may reflect the state of the body several months earlier.

Regular nail monitoring helps identify potential internal organ dysfunction early and guide dietary and lifestyle adjustments. It's a simple and intuitive way to take care of your health, accessible to everyone without complex tests or procedures.
