Thickened toenails are a common concern, especially as we age, but they’re not always caused by a fungal infection. While fungal toenails are a frequent culprit, other factors could be behind the changes in your nails’ appearance and texture. Understanding the cause is key to finding the right treatment and restoring nail health.
What Causes Thick Toenails?
Thick toenails may be caused by:
-
Fungal nail infections (onychomycosis) – the most common reason, often resulting in yellow, crumbly nails
-
Ageing – nails can naturally thicken and harden over time
-
Trauma or repeated injury – dropping something on your toe or wearing tight shoes can damage the nail
-
Psoriasis or skin conditions – can also affect the nails, making them thicker or pitted
-
Poor circulation or diabetes – may lead to nail changes due to reduced blood flow
-
Genetics – some people naturally have thicker nails
Treatment Options for Thick Toenails
The right treatment depends on the underlying cause:
-
Antifungal treatments – topical or oral medication to treat fungal infections
-
Debridement – gentle trimming and thinning of the nail by a podiatrist
-
Laser therapy – used in some cases to eliminate fungal infections
-
Footwear changes – wearing roomy, breathable shoes to reduce pressure on the nails
-
Nail care education – guidance on proper nail hygiene and maintenance
-
Podiatry assessment – essential for identifying the root cause and avoiding incorrect self-treatment
Your podiatrist may also take a nail sample for testing if the diagnosis isn’t clear.
Prevention Tips
Keep your feet clean and dry, wear breathable shoes, and trim your nails regularly (straight across, not too short). Avoid walking barefoot in public showers or pools, and see a podiatrist early if you notice nail changes.
