- Fungal infections: Fungal infections, such as onychomycosis, can lead to thickened nails. These infections are commonly caused by dermatophytes and often result in the nails becoming discolored, brittle, and thick.
- Trauma: Repeated or severe trauma to the toenail can cause thickening. This includes activities like stubbing the toe, wearing tight-fitting shoes, or participating in sports where the toes are frequently subjected to impact.
- Nail psoriasis: Psoriasis is a chronic skin condition that can affect the nails. In nail psoriasis, the nails become pitted, discolored, and thickened due to the abnormal growth of skin cells.
- Onychogryphosis: This condition, commonly known as ram’s horn nails, leads to the nails becoming excessively curved, thickened, and deformed. It is usually attributed to long-term neglect of proper nail care.
- Peripheral vascular disease: Poor blood circulation to the feet and toes, often associated with conditions like diabetes and peripheral artery disease, can result in thickened toenails.
- Genetics: Some individuals may have a genetic predisposition to thickened nails, which can be inherited.
It is important to consult a healthcare professional, such as a dermatologist or podiatrist, for diagnosis and appropriate treatment of thickened nails, as the underlying cause may require specific management.« Back to Glossary Index
