Onychomycosis, commonly known as a fungal nail infection, is primarily caused by fungal organisms. The most common culprits are dermatophytes, which are a group of fungi that can infect the skin, hair, and nails. However, other types of fungi, such as yeast (Candida) and molds, can also be responsible for nail infections.
The fungi that cause onychomycosis thrive in warm, moist environments. Factors that can contribute to the development of fungal nail infections include
Dermatophytes
These fungi are the most common cause of onychomycosis. The species Trichophyton rubrum and Trichophyton mentagrophytes are often implicated in nail infections
Yeasts
Candida species, commonly found in the mouth, digestive tract, and on the skin, can also infect nails. Candida onychomycosis is more common in individuals with weakened immune systems
Molds
Some molds can infect nails, but this is less common. Certain environmental molds may contribute to nail infections in rare cases
Several risk factors can increase the likelihood of developing onychomycosis, including
Age
The risk of fungal nail infections tends to increase with age
Trauma
Injuries to the nail or surrounding skin can create openings for fungi to enter and cause infection
Poor circulation
Conditions that affect blood flow to the extremities may make it easier for fungal infections to take hold
Weakened immune system
Immunodeficiency, whether due to diseases like HIV or conditions like diabetes, can increase susceptibility to fungal infections
Warm and humid environments
Fungi thrive in warm, moist conditions, making certain environments more conducive to infection
If you suspect you have onychomycosis, it's important to seek medical advice for an accurate diagnosis and appropriate treatment. Fungal nail infections can be challenging to eliminate, and professional guidance can help determine the most effective course of action based on the specific type and severity of the infection
