Nail Fungus vs Other Nail Problems
Discoloration, thickening, brittleness, crumbling and nail lifting can occur with fungal infection, but similar changes can occur for other reasons.
Why appearance can mislead
Psoriasis, nail injury and other conditions can resemble fungal nail infection. A healthcare professional may examine the nail and take a sample when confirmation is needed.
Why the distinction matters
Treatment depends on the cause. Diagnosed fungal nail infection may be treated with prescription topical or oral antifungal medication or other clinician-directed approaches. A dietary supplement should not be substituted for diagnosis or prescribed treatment.
When to get help
Seek professional evaluation for persistent or worsening changes, pain, swelling, spreading involvement, or if you have diabetes, circulation problems or immune-system concerns.
