Thickened toenails are common yet overlooked. They can hint at underlying problems. They’re caused by things like fungal infections, injuries, or medical conditions like diabetes and psoriasis.
Dr. Abigail Waldman, a dermatologist at Brigham and Women’s Hospital, says feet are good for fungi because they’re damp. Infections often start on the skin and spread to toenails.
Conditions like onychomycosis (new nail grows under an infected one) and onychauxis (causing curling and yellowing) are common. Injuries or immune issues can also thicken nails.
Symptoms include discoloration, brittleness, debris under nails, and bad smells. If not treated, these can lead to complications like tissue damage, nail loss, or infections spreading, which might cause serious health problems like cellulitis or sepsis.
Treating thickened toenails needs consistent care. It’s tough as meds often can’t get into the nail. Home remedies like soaking feet in a vinegar-water mix or using antifungal creams might help.
