How to Determine if It's a Fungal Nail Infection (Onychomycosis)

Onychomycosis, medically known as tinea unguium, is a common condition caused by fungal infection of the nail. To determine whether one has onychomycosis, observation and diagnosis can be made from the following aspects: 1. **Observe the nail appearance**: The typical characteristics of onychomycosis include thickening, deformation, discoloration of the nail, and even nail loss. If a patient notices such symptoms in their nails, it may be caused by onychomycosis. 2. **Examine the subungual skin**: Individuals with onychomycosis often experience thickening and roughness of the skin beneath the nail. One can check whether such changes have occurred in their own subungual skin. 3. **Watch for complications of onychomycosis**: Patients with onychomycosis may develop other dermatological conditions, such as tinea manuum (hand fungus) or tinea pedis (athlete's foot). If the nails exhibit the above symptoms, it may indicate the presence of onychomycosis. 4. **Family history**: If there are family members who have had onychomycosis, one's own risk of developing the condition may increase.
