- Trauma or injury: This could be due to repetitive pressure on the nail or a sudden impact, leading to separation of the nail from the underlying nail bed.
- Fungal infections: Fungal infections, such as onychomycosis, can cause the toenail to become thickened, discolored, and brittle, leading to separation from the nail bed.
- Psoriasis: People with psoriasis may experience onycholysis as a result of the condition. In psoriasis, the immune system attacks healthy skin cells, leading to inflammation and potential separation of the nail.
- Allergic reactions: Certain chemicals found in nail polish, adhesives, or nail treatments can cause an allergic reaction, leading to onycholysis.
- Medications or systemic conditions: Some medications or underlying health conditions can cause nail changes and potentially result in separation from the nail bed. Examples include certain antibiotics, chemotherapy drugs, hyperthyroidism, and iron deficiency anemia.
- Nail trauma from manicures: Improper trimming, excessive filing, or vigorous cuticle pushing during manicures can cause damage to the nail, leading to separation.
It is important to consult a healthcare professional if you are experiencing toenail separation to determine the underlying cause and receive appropriate treatment.« Back to Glossary Index
