What are the factors or causes of yellow fingernails in diabetes?

Patient's question:

I am a diabetic, and I only recently found out about the condition about a month ago. I have been taking medication for half a month and have also been controlling my diet very well. I went for a check-up, and there were no apparent issues, but in the past few days, I have noticed that my fingernails are turning yellow, and when I touch them, they seem uneven.

Doctor's answer:

Diabetes has many complications, and the specific complications can vary depending on individual constitution. However, yellowing of the nails is rarely seen, unless it is onychomycosis (fungal nail infection).
Advice: It could be onychomycosis. The treatment for onychomycosis primarily involves surgical methods, such as softening or removing the infected nail, followed by local application of antifungal creams or ointments. You can also use tincture of iodine or glacial acetic acid for treatment.
