Wide and flat fingernails can be a sign of various health issues, including respiratory problems, nutritional deficiencies, or certain skin conditions. Conditions like clubbing, often associated with lung disease, can cause nails to become wider and flatter. Additionally, a deficiency in vitamins such as biotin or essential fatty acids can affect nail shape. If you notice significant changes in your nails, it's advisable to consult a healthcare professional for a proper evaluation.
