When you think about signs of good health, your toenails might not be the first thing that comes to mind—but they should be. At Freeland Foot and Ankle Clinic, we’ve seen firsthand how changes in nail color, texture, or thickness can reveal a lot about what’s happening inside the body.
Here’s what your toenails could be telling you—and when it’s time to take a closer look.
Yellow or Discolored Nails
If your toenails are turning yellow or brown, one of the most common causes is a fungal infection. However, discoloration can also be linked to diabetes, circulation issues, or long-term smoking. Thick, brittle yellow nails that lift from the nail bed should never be ignored.
Treatment Tip: Freeland Foot and Ankle Clinic offers non-invasive laser therapy that effectively targets nail fungus without oral medications.
Thick or Misshapen Nails
Toenails that become thick, crumbly, or oddly shaped are often reacting to chronic pressure or trauma, such as from ill-fitting shoes. In some cases, they can indicate more complex issues like psoriasis or peripheral vascular disease.
If you're unsure whether your shoes are part of the problem, bring them with you to your appointment. Dr. Dailey can help determine if they’re contributing to the issue.
White Spots or Lines
Those small white marks—known as leukonychia—are usually harmless and often caused by minor trauma to the nail or nail matrix. While commonly misunderstood as a sign of calcium deficiency, they typically grow out over time with no treatment needed.
If white spots are persistent, widespread, or accompanied by other symptoms, it’s worth having them evaluated.
Dark Streaks or Bruises
Dark spots under the toenail can result from injury, especially if you've recently stubbed your toe or worn tight shoes. However, if a dark streak appears without explanation, grows in size, or doesn’t move as the nail grows, it could indicate a more serious issue, such as subungual melanoma.
It's essential to have unusual discoloration checked by a medical professional, especially if you have no known injury to the area.
Healthy Toenail Habits
Keeping your toenails healthy starts with everyday care. Dr. Dailey recommends the following habits to promote strong, clear, and fungus-free nails:
-
Trim toenails straight across and avoid cutting too short. This helps prevent ingrown toenails and reduces the risk of nail trauma.
-
Keep feet clean and dry, especially between the toes. Moisture creates the perfect environment for fungus to grow.
-
Wear shoes that fit properly and allow for airflow. Tight or poorly ventilated footwear can contribute to thickened or discolored nails.
-
Avoid going barefoot in public spaces like pools, locker rooms, or communal showers. These areas are hotspots for fungal infections.
-
Disinfect nail tools after every use, and never share them with others. Bacteria and fungus can spread easily through clippers, files, or pumice stones.
-
Let your toenails breathe by occasionally going sock-free at home or choosing breathable socks and materials.
-
Moisturize your feet and cuticles regularly. Dry, cracked skin around the nails can increase the risk of infection and discomfort.
-
Maintain a balanced diet rich in biotin, protein, iron, zinc, and other essential nutrients that support healthy nail growth.
In addition to these daily habits, consider scheduling regular foot checkups—especially if you have diabetes, poor circulation, or recurring nail problems. Routine care can catch issues early and help prevent complications before they start.
Remember, your toenails don’t just complete a pedicure—they reflect your overall health. Treat them well, and they’ll return the favor.
