What causes toenail fungus and how to fix it

Toenail fungus is quite common and you should pay attention if your nails appear discolored or thicker than usual.

It’s a common occurrence that can spread if you don’t fix it. Understanding the causes can help you take better care of your feet and cure the fungal infection before it gets worse or spreads.

Toenail fungus is usually not harmful and usually only affects the appearance of the nail. However, it can spread and get worse, so you don’t want to let it spread. It can also lead to other problems if left untreated.

Whether it’s sandal season or not, you don’t want to live with toenail fungus. Fixing it is easier than you might think, and you can try some home remedies before opting for other treatments.

The science behind nail fungus

Nail fungus can enter through cracks or cuts in the nail or skin, getting between the nail and the nail bed. The fungus thrives well on the toes because it can be hot and humid, especially if your feet sweat frequently.

A mold called dermatophyte sometimes causes toenail fungus and survives in the nail’s structural material called keratin. When this is the cause, it is called tinea unguium or onychomycosiswhich causes about 90% of fungal infections.

The fungus is contagious and you can catch it from other people or an infected surface. If you don’t treat it quickly, it can spread to other fingers or nails. You can also spread it to others if you don’t fix it before walking barefoot or making direct contact with others.

A fungal infection can spread

The fungus can infect other areas as well, and once it spreads it goes by many different names, including:

  • ringworm (on the skin)
  • athlete’s foot (the skin under your toes)
  • jock itch (in groin area)

Some of the common ways you can get toenail fungus include:

  • walk barefoot in public areas
  • contact in a locker room or shower
  • walk the perimeters of the pool

nail fungus prevention

Once the toenail fungus is gone, you can work to prevent it from coming back. These ideas include the following:

Keep your feet clean and dry

Good hygiene can make all the difference in preventing toenail fungus. Keep your feet clean and dry and wear socks that help wick away moisture.

Also, wear shoes that keep your feet dry and change your socks and shoes whenever they get wet. Also, wearing shower shoes in public areas can help keep your feet clean.

When washing your feet, use soap and water and then dry your feet thoroughly, especially between your toes. Cut your toenails straight across and make sure your tools are clean and sharp. This way you can ensure that you are not allowing any bacteria close enough to cause a problem.

do not use nail polish

You can cover the discoloration with nail polish, as this can prevent the nail bed from getting the air it needs. The fungus will not go away if the nail bed cannot breathe. Nail polish blocks air from reaching the nail bed and traps moisture, making the infection worse.

Avoid contact with fungi

If you have a family member with toenail fungus, avoid coming into contact with them. It may involve wearing flip flops in the shower, but it will be worth the extra effort.

Do not share shoes with other people

Sharing shoes can spread a yeast infection, so don’t wear someone else’s shoes or let them wear yours. Not sharing shoes is especially important when people don’t wear socks. Since toenail fungus is contagious, it’s best to avoid sharing it altogether.

change shoes regularly

Wearing the same pair of shoes every day increases the risk of nail fungus. You may not notice that your shoes are wet, so it’s best to change them frequently. Having a few pairs allows you to switch between them as needed.

keep your feet covered

You might think going barefoot is fine, especially around the house, but it’s not always safe. If you or a family member has had foot fungus, they may not have cleaned the house as well as they thought. Consider wearing socks or slippers even at home.

Final thoughts on how to get rid of toenail fungus

Using home remedies to cure toenail fungus can make all the difference without resorting to prescription drugs. These methods have fewer side effects and you can fix the problem instead of waiting for an appointment.

Home remedies sometimes take longer and you may not see results as quickly as you would like. If the fungus doesn’t go away, consider speaking to a healthcare professional for advice.

Once you get rid of toenail fungus, look for ways to prevent it from coming back. Prevention can go a long way in keeping you comfortable and avoiding unpleasant issues with a fungal toe infection. You will be happy with your effort when your feet remain in good condition.
