Nail Fungus: Causes, Symptoms, and Treatment
Causes of Fungal Nail Infections
Fungal nail infections, also known as onychomycosis, are caused by a group of fungi that thrive in warm, moist environments. The most common cause of fungal nail infections is Trichophyton rubrum, a fungus that also causes athlete's foot. Other fungi that can cause nail infections include Candida and Aspergillus.
Fungal nail infections can occur in anyone, but they are more common in people with certain risk factors, such as:
- Older adults
- People with diabetes
- People with weakened immune systems
- People who wear tight-fitting shoes
- People who frequently swim in public pools or showers
Symptoms of Fungal Nail Infections
Fungal nail infections can affect one or more nails. The most common symptom is a discoloration of the nail, which can range from white to yellow to brown. Other symptoms include:
- Thickening of the nail
- Crumbling or breaking of the nail
- Pain or discomfort
- A foul odor
Treatment of Fungal Nail Infections
Fungal nail infections can be difficult to treat, but there are a number of medications that can be used to kill the fungus. These medications are typically taken orally or applied topically to the affected nail. In some cases, surgery may be necessary to remove the infected nail.
If you have a fungal nail infection, it is important to see a doctor to get the proper diagnosis and treatment. Early treatment can help to prevent the infection from spreading and causing further damage to the nail.
