Green Nails

« Back to Glossary Index

Green nails, also known as green nail syndrome or chloronychia, is a nail condition characterized by the presence of a green discoloration in the nail bed or nail plate. It is usually caused by a bacterial infection, specifically Pseudomonas aeruginosa, which is commonly found in soil, water, and other environments.

When Pseudomonas aeruginosa enters the nail bed, it produces a green pigment called pyocyanin, leading to the green discoloration of the nail. Green nails can occur in both fingernails and toenails, but it is more commonly seen in toenails.

Apart from the green color, other symptoms of green nails may include nail weakness, brittleness, thickening, and sometimes a foul odor. The condition is typically painless, but if left untreated, it can lead to further complications and spread of the infection.

Treatment for green nails usually involves proper nail hygiene and removal of any infected nail material. In severe or persistent cases, oral or topical antibiotics may be prescribed by a healthcare professional to eliminate the bacterial infection.

It is important to consult a healthcare provider or dermatologist for an accurate diagnosis and appropriate treatment if you suspect you have green nails or any other nail abnormalities.
