Why Toenails Thicken and How to Treat Them
When prioritizing our overall well-being, our feet are frequently neglected right up until we pull off a sock and spot abnormally thick toenails. Many individuals simply dismiss this issue, particularly if they aren’t worried about cosmetics—because, let’s face it, how frequently do we truly examine our feet?
Causes of Thick Toenails
As explained by Dr. Abigail Waldman, a dermatologist at Brigham and Women’s Hospital, our feet are prone to being damp and sweaty. This creates the perfect breeding ground for naturally occurring skin molds, yeasts, and fungi to multiply and thrive. You can easily contract a fungal infection from walking barefoot in communal spaces like locker rooms and public swimming pools, or even after getting a pedicure at a nail salon. These infections usually begin on the skin of the toes or feet, potentially causing athlete’s foot before subsequently spreading to the toenails.
Various factors can trigger toenail thickening, ranging from physical injuries to specific medical conditions and fungal infections. Healthcare professionals will generally examine your toes to pinpoint the exact root cause and suggest the best course of treatment. The most common culprits include:
- Onychomycosis: A widespread type of toenail fungus that forces the body to generate a new nail underneath the infected one.
- Onychauxis: Also referred to as onychogryphosis, this condition can develop from physical trauma to the toe or systemic medical issues like psoriasis and diabetes. It typically results in nails that are curled, yellowed, or heavily thickened.
- Onycholysis: This happens when the nail plate physically separates from the underlying nail bed. It is frequently caused by excessive filing, allergic reactions, psoriasis, or direct nail injuries.
Symptoms to Watch For
While the underlying causes can trigger a variety of symptoms, there are several warning signs beyond just thickness that might point to a deeper medical issue. An infected toenail may present as:
- Chalky or scaly in texture
- Crumbled or severely split
- Physically lifted away from the nail bed
- Emitting a foul odor
- Discolored (turning brown, green, or yellow)
- Trapping an accumulation of debris underneath the nail
Potential Complications
Even though thick toenails are frequently viewed as just a cosmetic annoyance, ignoring them can pave the way for much more serious health complications. If left untreated, you may experience permanent tissue damage to the toes, complete nail loss, dangerous bacterial infections like cellulitis, infections that spread deep into the bones, and in extreme cases, sepsis.
