Toenail Fungus and Thickened Nails in Older Adults: Care and Treatment Options
How to recognise fungal toenail infection, why nails thicken with age and how to care for them at home. The role of podiatry and medical treatment.
Contents
Yellowing, thickened, brittle and misshapen toenails are very common in older people, and fungal infection (onychomycosis) is often behind them. Thick nails are hard to cut, press inside shoes and cause pain, and older people with poor vision or difficulty bending often cannot cut them themselves.
Signs
Yellow, brown or white discolouration; thickening; crumbling edges; separation from the nail bed; debris under the nail; sometimes a mild odour.
| Risk factor | Explanation |
|---|---|
| Older age | Slower nail growth, reduced circulation |
| Diabetes | Immune and circulation effects |
| Poor circulation | Reduced nail nourishment |
| Athlete's foot | Fungus can spread to nails |
| Damp, closed shoes | Ideal for fungal growth |
| Barefoot in communal areas | Pools, baths, gyms |
Not every thick, discoloured nail is fungal: psoriasis, repeated trauma and circulation problems can look similar, so a medical assessment and sometimes a nail sample are advised.
Treatment
Topical treatments for mild infections must continue until the nail regrows, often 9–12 months or longer. Oral medicines for extensive infection need checks for liver function and interactions, with extra care in older people.
Podiatry care is essential: thinning thick nails to reduce pressure and pain, removing infected material so topical treatment works better, correct cutting and sterile technique.
Prevention
Wash feet daily and dry between the toes, wear clean cotton socks, rotate and air shoes, wear sandals in communal areas, do not share nail clippers and treat athlete's foot.
