A number of sexually transmitted infections (STIs) are known to cause UTIs, including trichomoniasis and chlamydia
While most studies investigating chronic UTIs have focused on younger age groups, there is now compelling evidence that shows a strong relationship between sexual intercourse and UTIs in postmenopausal women.
It is, therefore, just as important for older women to take the same preventive measures as younger ones, irrespective of how often you have sex or how many sexual partners you have.
UTIs and Sexually Transmitted Diseases
Oftentimes a person will assume that the UTI is bacterial in nature (and treat it as such) and fail to identify the underlying STI.
It is, therefore, vital to consider your risk of STIs when any infection of the genitals or urinary tract is involved. This is especially true if you have multiple sex partners or have gotten a UTI after having sex with a new partner.
