Which condition could lead to nail discoloration?

Nail discoloration can often be a sign of underlying health issues, and poor nutrition is a significant factor that contributes to this condition. When the body lacks essential vitamins and minerals, such as biotin, iron, or zinc, it can affect the health and appearance of the nails. Nutritional deficiencies may lead to weaker nails that can become discolored or develop other visual symptoms.

Conversely, proper moisturization can help maintain the health and luster of nails, while regular filing generally promotes nail health by keeping them neat and reducing the likelihood of splits or breaks. The use of alcohol-based products typically aids in sanitization; while excessive use may dry out nails, it doesn't directly correlate with discoloration like poor nutrition does. Understanding the relationship between nutrition and nail health is crucial for addressing and preventing common nail issues, including discoloration.
