#6 Nails separate from their nail beds
Onycholysis is a disorder that usually causes no discomfort and is more likely to occur if your nails are longer. The most frequent reason is simple nail trauma, including excessive nail-filing or discomfort from chemicals used in manicures.
Occasionally, psoriasis or a fungal infection in the nail might also be linked to onycholysis. Moreover, a hormone condition called hyperthyroidism, which raises your metabolism, might be the cause of sudden and severe nail detachment.
Your doctor might not be able to diagnose the cause of your problem based solely on a physical examination because there are many possible causes for your nails to detach from their nail beds. You might also go through more testing, like a blood panel, to figure out what’s going on.
