Nail changes
Informed by recognized medical guidance
Overview
Nail changes refer to any difference in the appearance, texture, shape, or colour of your fingernails or toenails. They can be a sign of minor issues like injury or infection, or sometimes point to an underlying health condition.
Key facts
- Nails grow slowly; it can take 4-6 months for a fingernail to fully replace and 12-18 months for a toenail.
- Many nail changes are harmless and temporary.
- Changes can include ridges, spots, thickening, splitting, or discolouration.
Very common. Most people will experience some nail changes at some point in their lives.
Anyone can have nail changes, but they are more common in older adults, people with certain skin conditions (like psoriasis or eczema), and those with chronic illnesses such as diabetes.
