A spoon fingernail, also known as koilonychia, is a nail that is abnormally shaped, resembling a spoon.
Here's a breakdown of its appearance:
-
Concave Shape: The nail plate curves upwards, creating a depression in the nail.
-
Thin and Soft: The nail is often thinner and more pliable than a normal nail.
-
Ability to Hold Liquid: In severe cases, the concavity is deep enough to hold a drop of liquid.
-
Appearance: The overall appearance looks like a tiny spoon.
Here's an example of what a spoon fingernail looks like:
| Feature | Description |
|---|---|
| Shape | Concave, curved upwards |
| Thickness | Thin |
| Texture | Soft |
| Fluid Holding | May be able to hold a drop of liquid |
While the appearance is distinctive, it's essential to consult a medical professional if you suspect you have spoon nails. The condition can indicate underlying health issues, most commonly iron deficiency anemia. Other potential causes include trauma, exposure to petroleum-based solvents, lupus, thyroid problems, and more rarely genetic conditions. A doctor can properly diagnose the cause and recommend appropriate treatment.
