Thank you for getting in touch with us. As I see, your wife was most probably diagnosed with Candidiasis
and prescribed Nystatin
for that. It is a commonly seen fungal infection
seen in many individuals. If there are no additional signs and symptoms seen, then you need not worry about it. If there are any additional features, then we would recommend you to get a complete check up done to rule out other diseases. Often, poor immunity leads to candidiasis and other problems. Hope this helped.
