Identifying Toenail Fungus Through Pictures and Images
Toenail fungus is a common condition that can cause embarrassing symptoms. Viewing pictures and images of toenail fungus can help you determine if you may have a fungal nail infection versus other possible toenail issues.
By comparing your own toenails to photographic examples, you can recognize the distinct visual signs of a fungal infection. However, always confirm with a dermatologist, as other conditions can also affect toenail appearance.
Common Signs of Toenail Fungus
Some key characteristics that may indicate toenail fungus in pictures include:
- Thickened nail
- White or yellow streaks in the nail
- Crumbly, brittle, or distorted nail
- Debris buildup under the nail
- Nail separating from the bed
- Darkening or discolored nail
The more of these traits present, the more likely it is to be fungal nail infection. The symptoms tend to begin at the edge of the nail and spread toward the cuticle.
Mild Toenail Fungus Pictures
In mild or early cases of toenail fungus, you may notice:
- Slight yellow, brown or white streaks on the nail
- Subtle darkening or discoloration of the nail edge
- Minor nail thickening or crumbling
- Debris visible under part of the nail
- A small area of nail lifting from the nail bed
In mild infections, most of the nail still appears fairly normal. But leaving fungal nails untreated can allow them to worsen over time.
Moderate Toenail Fungus Pictures
In moderate or progressive toenail fungal infections, you may observe:
- White, yellow, brown streaks covering half or more of the nail
- Distinct darkening and discoloration of the nail
- Thickening and detachment of the nail from the nail bed
- Distorted, brittle or crumbly nail texture
- Debris clearly built up under the nail
The nail shape may start to become uneven or deformed. More of the nail detaches from the nail bed as the fungus advances.
Severe Toenail Fungus Pictures
In severe or longstanding toenail fungal infections, you are likely to see:
- Complete discoloration of the nail to yellow, brown, black, or green
- Extreme nail thickening, distortion, and detachment from the nail bed
- Brittleness, crumbling, or loose fragments of nail
- Large buildup of debris under the nail
- Nail that is nearly or fully destroyed
Advanced infections cause such extensive nail damage that the toenail may be painfully ingrown or need to be fully removed. Prompt treatment provides the best outcome.
Toenail Fungus Pictures by Type
There are a few different types of fungal infections that can affect the toenails. The visual symptoms may differ slightly depending on the type of fungus responsible.
Distal Subungual Onychomycosis
This is the most common type of toenail fungus. It appears as:
- White streaking and debris under the tip of the nail
- Nail thickening and lifting from the nail bed
- Yellowing, darkening, and discoloration of the nail
It typically starts at the nail edge and spreads toward the cuticle as the infection progresses.
Proximal Subungual Onychomycosis
This fungus enters through the cuticle and causes:
- White, powdery patches or streaks near the cuticle
- Nail thickening, detachment, and discoloration
- Eventual spread of symptoms toward the nail tip
A variant called Candidal PSO also involves redness and swelling of the surrounding skin.
White Superficial Onychomycosis
This fungal infection leads to:
- White, powdery patches or spots on the top of the nail
- No debris buildup under the nail
- A "snowy" appearance
In some cases, the spots gradually spread across the nail. It may eventually cause nail plate thickening.
Candidal Onychomycosis
This yeast fungal infection produces:
- Thick and brittle nails
- Red, swollen, painful surrounding skin
- Pus beneath the nail
- Nail darkening or discoloration in advanced stages
It typically affects multiple nails, especially in people with weakened immune systems or diabetes.
Toenail Fungus vs. Other Nail Conditions
While toenail fungus is highly common, other conditions can also make nails appear abnormal. Comparing pictures helps differentiate fungal infections from problems like:
Psoriasis
Nail psoriasis symptoms include:
- Pitting, grooves, or roughness of the nails
- Discoloration and crumbling of nail edges
- Separation of the nail plate from the nail bed
- Red patches or silvery scale on surrounding skin
Nail Trauma
Injuries to the nail cause:
- Bruising and blood under the nail
- Black and blue discoloration
- Nail separation if the trauma pulls off the nail plate
This is usually due to a single incident like stubbing the toe rather than a progressive infection.
Bacterial or Viral Infections
These may appear as:
- Greenish, dull, or streaky discoloration
- Sudden onset of symptoms rather than gradual
- Pus or foul odor from beneath the nail
Redness, warmth, and significant pain often accompany an acute infection.
Nail Pitting
Pitting can look like the early stage of fungal infection. However, the nail texture is often still smooth rather than thick or crumbly. There is no debris under the nail.
Yellow Nail Syndrome
This condition causes:
- Very thick, yellow, slow-growing nails
- No nail detachment or debris buildup
- May be accompanied by respiratory issues
Melanonychia
Dark brown or black streaks in the nail can signify:
- Ethnic background
- Medications
- Past trauma
- Moles
- Rarely, melanoma
These vertical streaks differ from the horizontal yellow/white streaking caused by fungus.
Getting an Accurate Diagnosis
While comparing your toenail appearance to pictures can provide clues, only a doctor can diagnose a fungal nail infection. See a dermatologist if you notice any unusual nail changes.
The doctor will examine your nails and ask about your health history. They may scrape nail debris for laboratory testing to confirm fungus.
It's essential to get the right diagnosis, as treatment varies depending on the cause. Prescription antifungal medication is needed for fungal infections. But incorrectly using these drugs for another condition could worsen nail problems.
Diagnosing and promptly treating toenail fungus provides the best chance of restoring healthy, clear nails. Always consult a doctor if you have any nail abnormalities.
