What Happens If You Ignore Toenail Fungus?
Toenail fungus may seem like a minor cosmetic problem, especially when it starts with a small change in the color or thickness of one toenail. But fungal nail infections can become more difficult to treat when they are ignored.
A fungal infection can gradually spread across the nail and potentially affect other toenails or the surrounding skin. For patients in Sugar Land and Houston, getting an accurate diagnosis and appropriate treatment can help prevent a small nail problem from becoming a persistent one.
At Advanced Foot & Ankle Specialists, we evaluate and treat toenail fungus and other nail conditions using modern treatment options designed around each patient’s needs.
What Does Toenail Fungus Look Like?

Toenail fungus, also called onychomycosis, can cause noticeable changes in the appearance and texture of the nail.
Common signs include:
- Yellow, white, or brown discoloration
- Thickened toenails
- Brittle or crumbly nails
- Nails that become distorted or misshapen
- Separation of the nail from the nail bed
- Debris accumulating underneath the nail
- Unpleasant odor in some cases
Toenail fungus often develops gradually, so it may be easy to overlook in its early stages.

Can Toenail Fungus Get Worse If You Leave It Alone?
Yes. Toenail fungus typically does not disappear without treatment.
As the infection progresses, the nail may become increasingly thick, brittle, and difficult to trim. The infection can also spread to additional nails or to the surrounding skin.
In some people, the affected nail becomes uncomfortable when wearing shoes or walking because the thickened nail creates additional pressure against the inside of the shoe.
Can Toenail Fungus Spread to Other Parts of the Body?
Fungal infections can spread.
For example, the same fungus that causes a toenail infection can contribute to athlete’s foot, which commonly causes itching, scaling, cracking, or irritation between the toes and on the soles of the feet.
The infection can also potentially spread from one toenail to another.
This is one reason treating a fungal nail infection and practicing good foot hygiene are important.

Why Is Toenail Fungus So Difficult to Treat?
Toenails grow slowly and have a relatively limited blood supply compared with other parts of the body. This can make fungal nail infections particularly persistent.
Even after the fungus has been eliminated, the damaged portion of the nail doesn’t immediately look normal. The healthy nail must grow out gradually.
Depending on the individual and the extent of the infection, restoring the appearance of the nail can take many months.
Is It Always Toenail Fungus?
Not necessarily.
Several other conditions can cause nails to become thick, discolored, or distorted. Trauma, psoriasis, nail disorders, and other conditions can sometimes look similar to a fungal infection.
That’s why an accurate diagnosis is important before beginning treatment.
At Advanced Foot & Ankle Specialists, your podiatrist can examine the affected nail and determine whether fungus is actually responsible for the changes you’re seeing.
Who Should Be Especially Careful About Toenail Fungus?

While anyone can develop a fungal nail infection, people with certain health conditions may need to be particularly proactive about foot and nail problems.
If you have diabetes, circulation problems, or a weakened immune system, even a seemingly minor foot or nail problem deserves professional attention.
Early evaluation can help identify potential complications and ensure that treatment is appropriate for your overall health.
What Treatments Are Available for Toenail Fungus?
Treatment depends on the type and severity of the infection.
Depending on your situation, treatment may include:
- Topical antifungal medication
- Oral antifungal medication when appropriate
- Professional nail care
- Advanced laser treatment
- A combination of treatments
At Advanced Foot & Ankle Specialists, we evaluate the condition of your nail and discuss the treatment options most appropriate for you.
Advanced Treatment for Toenail Fungus
Advanced Foot & Ankle Specialists offers PinPointe FootLaser as an in-office treatment option for fungal toenails.
Laser treatment uses targeted light energy to address the fungal infection without the need for an incision. Your podiatrist can determine whether this treatment is appropriate based on the condition of your nails and your overall foot health.
How Can You Help Prevent Toenail Fungus From Coming Back?
Even after successful treatment, reinfection is possible because fungi are common in the environment.
You can reduce your risk by:
- Keeping your feet clean and dry
- Drying carefully between your toes
- Changing socks regularly
- Wearing breathable footwear
- Avoiding walking barefoot in public showers and locker rooms
- Wearing protective footwear around swimming pools
- Avoiding sharing shoes, socks, or nail tools
- Keeping toenails trimmed properly
- Disinfecting footwear when appropriate
Good foot hygiene is an important part of both treatment and prevention.
Don’t Ignore Changes in Your Toenails
A discolored or thickened toenail may seem harmless, but ignoring it can allow an infection to become more established and harder to manage.
If you notice persistent changes in your toenails, especially if the condition is spreading or causing discomfort, professional evaluation can help determine what’s actually causing the problem.
