Question 1

Can nail fungus be cured?

Accepted Answer

Yes. Nail fungus is often curable with proper treatment. Oral antifungal medications—particularly terbinafine—offer the highest cure rates (55–70%), while prescription topical medications like efinaconazole have moderate success rates. However, treatment can take many months, and recurrence is possible without preventive measures.

Question 3

How does nail fungus start and spread?

Accepted Answer

Nail fungus typically begins when fungi enter the nail bed through small cuts or cracks. It often spreads in environments where feet are exposed to moisture for long periods-like sweaty shoes or communal showers. People with weakened immune systems or poor circulation are at higher risk.

Question 4

What does nail fungus look like?

Accepted Answer

Infected nails may appear discolored (yellow, brown, or white), thickened, brittle, crumbly, or distorted in shape. As the fungus progresses, the nail may separate from the nail bed or emit a mild odor.

Question 5

Can nail fungus go away on its own without treatment?

Accepted Answer

In most cases, nail fungus does not go away on its own. Without treatment, the infection may worsen and spread to other nails or skin. Early treatment can prevent long-term nail damage and discomfort.

Question 6

Which treatment works best for nail fungus?

Accepted Answer

Oral antifungal medications—such as terbinafine and itraconazole—are most effective, especially for moderate to severe cases. Topical options may help milder infections or be used alongside systemic therapy.
