Do UTIs affect menstrual cycles?
UTIs do not directly affect menstrual cycles, but severe infections and the associated stress can occasionally cause delayed or missed periods in some women.
Detailed Medical Explanation
Urinary tract infections are caused by bacteria affecting the urinary tract, not the reproductive system. However, illness, physical stress, or use of certain antibiotics can sometimes temporarily alter your cycle. If you experience persistent changes, consult your GP. NHS: UTI and periods.
Clinical Context
Clinics reassure women that UTIs rarely affect menstrual health directly. Prolonged or unusual period changes should always be evaluated.
Evidence-Based Approaches
NHS and NICE do not consider UTIs a direct cause of cycle disturbances, but illness and stress can impact menstrual health in some cases.
