Look all the way down to your toes. You might be surprised to learn they're more important than you might think. Toenails often serve as barometers of health, according to the American Podiatric Medical Association.
Take action: Look out for the following: the pitting of nails and increased nail thickness – these could be manifestations of psoriasis; nails that are rounded inward instead of outward – this can foretell iron deficiency anaemia.
Consult your doctor when you notice any discolouration or infection on or about the nail.
