Nail fungus, medically known as onychomycosis, is a common fungal infection of the toenails or fingernails. It can lead to discoloration, thickening, and brittleness of the nails. Here are some key points about nail fungus:

1. Causes: Nail fungus is typically caused by dermatophytes, a group of fungi. It can also be caused by yeast or molds. These fungi thrive in warm, moist environments and can enter the nail through small cracks or injuries.

2. **Symptoms:** Symptoms of nail fungus may include thickening of the nail, yellowing or discoloration, nail brittleness, and a distorted or crumbly appearance. In some cases, it can lead to pain and discomfort.

3. **Risk Factors:** Certain factors increase the risk of developing nail fungus, including aging, having a weakened immune system, wearing tight shoes, sweating excessively, and having a history of athlete's foot.

4. **Treatment:** Treating nail fungus can be challenging, and it often requires patience. Treatment options include topical antifungal creams, oral antifungal medications, medicated nail polish, and in severe cases, surgical removal of the nail.
