What is Nail Fungus?

A nail fungus causes thickened, brittle or crumbly nails. The fungus is not normally painful but can be quite unsightly. There are several effective treatments available. This is not a problem that will resolve on its own, medical intervention is normally required.

Nail Fungus Treatment in Largo, FL

Thick, Discolored, or Crumbling Nails? We Can Help.

Nail fungus, or onychomycosis, is a common and persistent condition that affects the fingernails or toenails — most often the toes. It’s not usually painful, but it can cause discoloration, thickening, crumbling, and even nail detachment. At Meira Dermatology, we provide effective medical treatments to restore nail health and stop the spread of infection.

What Is Nail Fungus?

Nail fungus is a fungal infection of the nail bed, nail plate, or surrounding tissue, typically caused by:

  • Dermatophytes (the most common culprits)
  • Yeasts (like Candida)
  • Molds (especially in warm, humid environments)

 

The infection may start as a small white or yellow spot under the nail and can gradually lead to:

  • Thickened nails
  • Brittle or crumbly texture
  • Discoloration (yellow, brown, white, or black)
  • Distorted shape
  • Foul odor
  • Nail separating from the nail bed (onycholysis)
How Is Nail Fungus Contracted?

Fungal nail infections are highly contagious and often spread through:

Walking barefoot in public showers, gyms, and locker rooms

Wearing tight, non-breathable footwear

Sharing nail tools, towels, or socks

Having sweaty feet or moist skin

Pre-existing conditions like athlete’s foot, diabetes, or weakened immune system

Treatment Options at Meira Dermatology

Nail fungus typically does not go away on its own and becomes harder to treat over time. We offer a variety of FDA-approved and evidence-based solutions, including:

Oral antifungal medications – Most effective for deep or stubborn infections

Topical antifungal treatments – Applied daily to infected nails and cuticles

Laser therapy – Targets fungal cells with no downtime or systemic side effects

Nail debridement – Trimming and thinning thickened nails for better treatment penetration

Surgical nail removal – For severe or painful infections unresponsive to other methods

Hygiene counseling and prevention – To stop recurrence and spread

When to Seek Treatment

Consult us if you notice:

  • yellow or white spot spreading on the nail
  • Nails becoming thick, discolored, or brittle
  • Multiple nails showing signs of infection
  • Nail pain or separation from the nail bed

 

Early intervention helps prevent complications and speeds up healing.

Preventing Nail Fungus

To reduce your risk:

  • Keep feet and hands clean and dry
  • Change socks daily and wear breathable shoes
  • Avoid walking barefoot in shared spaces
  • Disinfect nail clippers and tools regularly
  • Choose reputable nail salons that sterilize equipment
  • Apply antifungal powders or sprays if prone to infection
