Nail fungus, also known as onychomycosis, is a common condition that causes the nails to become thick, discolored, and brittle. It is usually caused by a fungal infection, but can also be caused by other factors, such as a bacterial infection or damage to the nail. Nail fungus is more common in toenails than in fingernails and is more likely to occur in older adults.
If you have nail fungus, it is important to seek treatment as soon as possible to prevent the infection from spreading and causing further damage to the nails.
It is important to practice good hygiene, such as washing your hands and feet regularly and drying them thoroughly, to help prevent the development of nail fungus. If you are at high risk for nail fungus, such as if you have diabetes or a weakened immune system, it is especially important to take precautions to protect your nails.
