Nail color change

Nail color change is a symptom that can occur in a variety of conditions. It is characterized by a change in the color of the nail, from the normal pinkish hue to a yellow, green, blue, or even black shade. This symptom may develop gradually or suddenly and may be a sign of an underlying medical condition. The type and severity of the color change can vary depending on the underlying cause. For instance, yellow nails may be caused by fungal infection, while green nails can be a sign of bacterial infection. In some cases, a change in nail color can also indicate a vitamin or mineral deficiency or other medical condition.
