What Causes White Spots on Nails?

Common causes of nail white spots include nail trauma, onychomycosis (fungal nail infection), and nail malnutrition. Nail trauma is the most frequent cause, including mechanical injuries as well as chemical damage from manicures and nail polish commonly used by women. In such cases, a history of injury or manicure use is usually present. The condition typically requires only observation and protective measures. Additionally, white spots may appear on the nails of individuals deficient in zinc.

It is recommended to visit a hospital for serum trace element testing to check zinc levels. Fungal white nail disease (leukonychia due to fungal infection) is another common cause and a form of onychomycosis. A definitive diagnosis can be made through fungal examination of nail clippings. Treatment with oral antifungal medication should be conducted under a doctor's supervision. There's no need to panic upon discovering white spots—consult a dermatologist if you're unsure of the cause.

In daily life, eat more fresh fruits and vegetables rich in vitamins to ensure adequate vitamin intake and prevent deficiencies that could lead to health problems. Maintain a balanced diet with proper mix of meat and plant-based foods, engage in outdoor activities regularly, and keep a positive mood to reduce the risk of illness.
