What does white spots on nails indicate about the body?

With the changing times, people today are increasingly focused on health and prevention. Many diseases can be detected through changes in various parts of the body. For example, white spots under the fingernails—what do these white spots indicate about your health?

What Does It Mean When There Are White Spots on Your Nails?

Common causes of white spots on nails include nail trauma, fungal infection (tinea unguium), and nail malnutrition. Trauma is the most frequent cause, including mechanical injury or chemical damage from manicures and nail polish commonly used by women. If there's a history of injury or manicure, simply monitor the condition and take preventive measures in the future. Additionally, zinc deficiency can also lead to white spots on the nails.

If white spots appear on the nails, it’s advisable to have a blood test for serum trace elements to check zinc levels. Increase dietary intake of zinc-rich foods such as seafood, fish, and shrimp, and supplement zinc appropriately. Fungal white nail infection (a type of tinea unguium) is another common cause. A definitive diagnosis can be made through fungal testing of nail clippings. Treatment requires oral antifungal medication under a doctor’s supervision. There's no need to panic upon discovering white spots—consult a dermatologist if you're unsure.

In daily life, maintain good personal hygiene: wash hands before meals, eat a varied diet, and engage in outdoor activities regularly to boost immunity. Have a physical examination annually so any health issues can be detected and treated early, preventing disease progression. We hope this information has been helpful.
