What Is Nail Fungus?

Nail fungus, medically known as onychomycosis, is a fungal infection that affects fingernails or toenails. It often starts as discoloration or thickening of the nail and can progress if left untreated. Over time, the nail may become brittle, crumble, or separate from the nail bed.

This condition is caused by fungi, which thrive in warm, moist environments. The infection primarily affects toenails but can also develop in fingernails. While it may seem cosmetic at first, untreated onychomycosis can lead to discomfort and additional complications, particularly for people with diabetes.

What Causes It?

Nail fungus is caused by fungal organisms entering through tiny cuts or separations around the nail. These organisms grow quickly in conditions like damp socks, public showers, or shared nail tools. Certain risk factors, such as aging or immune system issues, can increase the likelihood of developing onychomycosis.

People with diabetes are more prone to nail fungus due to several reasons. Reduced blood circulation in the feet commonly affects people with diabetes. Poor circulation weakens sensation in the feet and slows the healing of small cuts or injuries where fungi can enter. These conditions make people with diabetes more susceptible to fungal infections.

Having diabetes also increases the risk of complications from infections. Left untreated, a fungal infection may result in long-lasting damage to the structure of the nails or spread to other areas of the skin. For individuals with poor blood circulation, this spread could lead to wounds or infections that heal slowly, becoming more difficult to manage.

How Can It Be Managed and Treated?

Treating nail fungus involves a combination of self-care and medical interventions. For milder cases, over-the-counter antifungal creams or nail lacquers may help. Regularly trimming and cleaning infected nails can also play a role in management. While these methods may help alleviate symptoms, they often work well when combined with professional treatment.

For more persistent or severe cases, consulting a healthcare provider is advised. They might suggest prescription-strength antifungal medications taken orally or applied directly to the nail. Laser treatments or nail removal may also be recommended in specific situations.

Preventative care is a key component of managing onychomycosis for people with diabetes. Keeping feet dry, wearing breathable socks, and using footwear in public spaces, like gyms or swimming pools, can reduce exposure to fungi. Paying close attention to foot hygiene and monitoring nails for any changes can make a difference when it comes to early detection of nail fungus.

Stay Ahead of Nail Health

Nail fungus may seem minor, but it holds unique challenges and risks for individuals with diabetes. Understanding how this condition develops and why people with diabetes are more susceptible can better prepare individuals to address it proactively. While self-care practices can help, speaking with a healthcare provider is the safest way to develop an effective treatment plan. Start prioritizing your nail health today.
