What causes white fingernails on all ten fingers?

Generally, having ten fingernails appear white may be caused by factors such as nutritional deficiencies, trauma, or infections. Treatment methods vary depending on the underlying cause. Specific analyses are as follows:

1. Nutritional deficiency

A lack of nutrients such as vitamin B12, calcium, or iron can lead to pale nails. In daily life, it is advisable to consume more foods rich in vitamins and essential nutrients, such as milk, eggs, and lean meat.

2. Trauma

Injury or bruising to the nail can also result in whitening. In such cases, it is important to keep the nail dry and clean to prevent infection.

3. Infection

Bacterial or fungal infections of the nail can also cause the nail to turn white. Under a doctor's guidance, medications such as itraconazole capsules or minocycline hydrochloride tablets may be used to treat nail infections.

In addition, conditions such as anemia, liver disease, or kidney disease may also lead to pale nails. If nail whitening is severe or accompanied by other symptoms, prompt medical attention is recommended for accurate diagnosis and appropriate treatment. Also, avoid using cleaning agents or detergents containing chemicals to prevent damage to the nails.
