Is Sergio likely suffering from a fungal, bacterial, or yeast infection?

Cause of Sergio's Nail Symptoms

Sergio's symptoms of thickening and discoloration of the nail of his index finger are indicative of a nail infection, which is often caused by a fungal infection, although bacterial and yeast infections can also be responsible.

Sergio is likely suffering from a fungal infection, which is a common cause of nail infections. Fungi, such as dermatophytes, can infect the nails, especially when exposed to humid and warm conditions. Small cracks in the nail or the area around the nail bed provide entry points for fungus spores.

The symptoms of nail fungal infections include thickening and discoloration of the nail, which may turn yellow or brown and become brittle. In more severe cases, the nail may even separate from the nail bed.

Diagnosis of nail infections involves a physical examination by a physician and possibly a sample from the infected nail to identify the presence of fungus or other infections.

Treatment options for nail infections include oral antifungal drugs, topical antifungal treatments, or surgical nail removal in extreme cases. Prevention measures include wearing breathable footwear, keeping nails clean and dry, and avoiding barefoot exposure in public areas like gyms and swimming pools.

Following the doctor's instructions for treatment is essential for Sergio to prevent the nail infection from worsening and promote healing of the affected nail.
