Nail Infection Treatment

What is a fungal nail infection?

A fungal nail infection, also known as onychomycosis, begins with the development of a spot under the fingernail or toenail, typically appearing white or yellow. As the infection progresses, it can lead to thickened nails with a crumbled edge. While more common in toenails, fungal nail infections can also affect fingernails.

Symptoms of a fungal nail infection

A fungal nail infection, often starting as a discoloration of the nail, can intensify and spread to other nails. Symptoms include:

  • Thickened nails

  • Yellow or brown discoloration

  • Brittle, crumbly, or ragged nails

  • Distorted nail shape

  • Slightly pungent odor

What causes fungal nail infections?

Fungal nail infections result from an overgrowth of fungi around the nail. Fungi thrive in warm, moist conditions and can spread from person to person. Contact with someone carrying a fungal infection can lead to transmission. Although these infections can occur in both fingernails and toenails, they are more prevalent in toenails due to the conducive environment created by enclosed shoes.

Individuals with diabetes face an elevated risk of fungal nail infections due to reduced blood flow to the feet and compromised circulation. High blood sugar levels in diabetes can also weaken the body's ability to combat fungal nail infections.

How are fungal nail infections treated?

Fungal nail infections can be challenging to cure and often require intervention. Treatment typically involves prescription antifungal pills, and it may take several months to a year for the infection to fully resolve. In some cases, treatment may not completely eradicate the infection, leading to potential recurrences. Severe cases may necessitate referral to a healthcare provider for complete nail removal.

How can I prevent a fungal nail infection?

Preventive measures to avoid nail fungus include:

  • Regular hand and foot washing

  • Moisturizing nails after washing

  • Trimming fingernails straight across, smoothing edges, and disinfecting nail clippers

  • Wearing sweat-absorbing socks and changing them as needed

  • Choosing breathable shoes and treating them with disinfectants or antifungal powders

  • Avoiding walking barefoot in public bathing areas
