Onychomycosis: What You Need to Know About This Common Nail Infection
Published: Oct 15, 2023
Onychomycosis is a fungal infection that targets your nails, causing them to look unsightly and sometimes painful. Understanding its causes and treatments can help keep your nails healthy.
What Causes Onychomycosis?
The primary culprits of onychomycosis are dermatophytes, with Trichophyton rubrum being the most common. Yeasts like Candida albicans and nondermatophyte molds can also be responsible. These fungi thrive in warm, moist environments, making feet a common target, especially if you frequent damp areas like pools or locker rooms.
Who Should Be Treated?
Not everyone with onychomycosis needs treatment, but certain groups should consider it. If you have diabetes, repeated cellulitis, or are immunocompromised, treatment is advised to prevent serious complications. Additionally, those experiencing pain or discomfort, or who are concerned with nail appearance, may benefit from treatment.
Treatment Options
Treatment varies based on severity and type of fungus. Mild cases might only need topical antifungals, while severe cases often require oral medications like terbinafine. Other options include laser therapy and surgery, though these are less common. It's essential to complete the full treatment course to prevent recurrence.
