Toenail fungus, also known as onychomycosis, is a common nail infection that affects many people worldwide.

It is usually caused by a type of fungi called dermatophytes, which thrive in moist and warm environments, such as shoes, socks, and public showers. The fungus can invade the toenails and cause them to become thick, discolored, and brittle. In severe cases, it can cause pain, inflammation, and even complete loss of the toenail. Here are some of the common causes and symptoms of toenail fungus.

Causes of Toenail Fungus

Toenail fungus is caused by a variety of factors, including:.

Poor hygiene

Poor hygiene can increase the risk of developing toenail fungus. If you don’t keep your feet clean and dry, the fungus may thrive on your nails. Make sure to wash your feet regularly, dry them thoroughly, and change your socks daily.

Wearing tight-fitting shoes

Wearing shoes that are tight or don’t fit properly can cause your toes to sweat and create a warm, moist environment that is ideal for fungal growth. Choose shoes that allow your feet to breathe and keep them clean and dry.

Walking barefoot in public places

Walking barefoot in public places, such as gyms, swimming pools, and locker rooms, can expose your feet to fungi and increase your risk of developing toenail fungus. Wear flip-flops or sandals in these areas to protect your feet.

Weakened immune system

If you have a weakened immune system due to a medical condition, such as diabetes or HIV, you may be more susceptible to toenail fungus. This is because your body is less able to fight off infections.

Symptoms of Toenail Fungus

The symptoms of toenail fungus can vary depending on the severity of the infection, but they often include:.

Thickened nails

One of the most common symptoms of toenail fungus is thickened nails. The infected nails may become thicker than usual and may be difficult to trim or cut.

Discoloration

Toenail fungus can cause your nails to become yellow, brown, or even black. The color of the nail may also appear blotchy or streaky.

Brittleness

Infected nails may become brittle and prone to breaking or crumbling. This can make it difficult to perform everyday activities, such as walking or standing for long periods of time.

Unpleasant odor

In some cases, toenail fungus can cause your nails to emit a foul odor. This can be embarrassing and uncomfortable.

Lifting of the nail

If the infection is severe, it may cause the nail to lift off from the nail bed. This can be painful and may lead to further complications.

Conclusion

While toenail fungus can be an uncomfortable and embarrassing condition, it is treatable. There are various over-the-counter and prescription medications that can help eliminate the fungus and restore the health and appearance of your nails.

However, it’s important to maintain good foot hygiene and avoid walking barefoot in public places to prevent future infections.
