Your nails say a lot about your general health, and even small changes in their appearance can reveal more than you think.
Your nails say a lot about your general health, and even small changes in their appearance can reveal more than you think.
Most nail changes aren’t caused by anything serious, but some can suggest that you have low levels of certain vitamins or minerals, or an underlying condition that needs medical attention.
Heart, lung and thyroid disease are just some of the more serious conditions your nails can provide clues about.
But to spot these clues, you’ll need to know what healthy nails look like and the changes that suggest that something may be wrong.
Healthy nails are even in colour, free of any pits or grooves, and feel smooth to the touch.

If you do lose a nail after an injury, it can take up to 6 months for a fingernail to grow back and 18 months for a toenail to do the same. If an injured nail hasn’t grown back after this time, see a doctor.
Nail health is linked to how well your body is functioning and changes in your body can sometimes be seen in them.
So, what type of changes should you look out for?
Keep an eye out for any of the following:
See a doctor if you notice a change in the texture, colour, thickness or shape of any of your nails and you’re not sure why.
Also see a doctor if any of your nails fall off unexpectedly. It’s natural for a toenail to change colour and drop off if you’ve injured it, but a healthy nail shouldn’t fall off for no reason. If it does, this may be a sign of a health condition.
