Most people assume that anything that makes toenails thick and ugly must be a fungal infection. That may not always be the case. Toenails too thick to trim with standard clippers might also be caused by a bacterial infection. Anti-fungal treatment won’t work for such a problem. One reader says that Neosporin (bacitracin, neomycin, polymyxin) works against thick toenails caused by a bacterial infection.
Mehaz for Toenails Too Thick to Clip:
Q. Not long ago, you wrote about toenails too thick to clip. I’ve had this problem and use a wide-jaw toenail clipper by Mehaz. It does the trick.
Not all hard, thick toenails are caused by fungal infections. I’ve been dealing with this for seven years on both my big and little toes.
My primary physician wasn’t concerned, saying it’s just cosmetic. Nonetheless, I’ve tried lots of prescription and non-prescription medications, to no avail.
Recently, I saw a podiatrist who took specimens of the nails for analysis. The problem wasn’t fungal, but rather bacterial. He recommended an inexpensive antibacterial ointment such as Neosporin.
It’s working wonders. Three of the nails are clear and the fourth, the worst, has but a speck remaining.
A Spelling Bee Brain Buster: Onychauxis:
A. I will bet that unless you are a dermatologist or a podiatrist, you have never heard of the word onychauxis. I’ll double that bet if you think you know how to pronounce onychauxis. That is the medical term for toenails too thick to clip.
Want to know how to pronounce it? Here is a link. Did I win the bet? But wait…here is another way to pronounce onychauxis. But wait, it gets worse: onychauxis. And here is the pronunciation of onychauxis with British, Australian and American English. Why do dermatologists come up with such tongue twisters for something as simple as thickened toenails? By the way, the medical term for a separation of the toenail from the finger is onycholysis and the term for nail fungus is onychomycosis. More about these terms in a few seconds.
Although thick, discolored nails are often caused by fungal infections, other conditions, such as psoriasis, can also create this problem. One study found that 32 percent of patients with nail disorders did not have detectable fungi (Journal of Cosmetic Dermatology, July 2021).
The authors conclude:
“Although fungal pathogenic agents are mostly detected among the diseases causing color changes and deformities in the nails, it should be kept in mind that nail findings of systemic or other skin diseases may mimic onychomycosis and the diagnosis should be confirmed by laboratory tests in addition to clinical manifestations for accurate treatment.”
In a different study, researchers used DNA sequencing and found that half of the toenail infections were bacterial (Journal of the American Podiatric Medical Association, March 1, 2021).
The authors provide this background:
“It is well established and accepted that fungi are a major contributing factor in nail dystrophy. It has also been recognized that bacteria play a crucial role in onycholysis. However, the bacteria and fungi that can be grown on culture media in the laboratory are only a small fraction of the total diversity that exists in nature.”
“Toenails tested with DNA sequencing demonstrated the presence of both bacteria and fungi in many samples. Further work is required to fully investigate its relevance to nail pathology and treatment.”
What to Do About Toenails Too Thick to Clip?
A diagnostic workup makes sense, especially if the nail problem has not responded to standard treatments. Toenails grow slowly, so it can take months for them to grow out healthy.
