Frequently asked questions
Is a yeast infection an STI?
No. Thrush is an overgrowth of a fungus that normally lives in the body and is not classed as a sexually transmitted infection, though sex can sometimes trigger it.
Why do I keep getting infections?
Recurrent infections can be linked to diabetes, antibiotics, hormone changes or irritants. If they keep coming back, see a doctor to check blood sugar and review triggers.
