What causes pits on fingernails?

First, it may be caused by iron deficiency anemia. If the nails are concave, it is likely directly related to iron deficiency. In fact, iron deficiency itself will not cause nail deformities, but if your body lacks iron, the amount of cystine inside the nails will be far lower than normal, so depressions will appear. Second, it may be the result of heavy physical labor. Because of continuous heavy physical labor, the blood circulation at the end of the nail is blocked, causing the nail to become concave. Third, it is possible that the blood flow at the end of the nail is blocked due to long-term contact with cold water.

The above is my personal answer to the question of why there are pits on fingernails. In general, if there are pits on the nails, it may be due to iron deficiency anemia, or it may be caused by long-term heavy physical labor, exposure to cold water, and other reasons. You can further determine and deal with it based on your actual situation.
