Thick Toenails
Toenails will often become thick as an individual grows
older. Thickening may also occur as a result of trauma to the toenail, such as
when it repeatedly hits the end of a shoe that is too short. Sometimes when
something is dropped on the toenail, the nail will fall off. When a new toenail
grows back it will often be thicker than it was previously.
Thick toenails can also be seen in individuals with nail
fungus (onychomycosis), psoriasis, and hypothyroidism. Those who have problems
with the thickness of their toenails should consult a foot and ankle surgeon
for proper diagnosis and treatment.
