Explanation

When nail beds turn black, it might be due to different reasons. One cause could be contact with certain substances like elemental iron, which can change the nail color, a condition known as chromonychia. Another potential cause could be related to changes in the body due to liver disease, which can also affect nails.

Additionally, nail changes have been observed in individuals with specific conditions like hemiplegia, which is paralysis on one side of the body. This condition might lead to nail pathology, although the exact appearance of the nails can vary.

If you notice your nail beds turning black, it is important to consider any recent exposures to substances or changes in your health. It might be helpful to consult with a healthcare provider to explore these possibilities and determine the cause.
