Which habits may reduce recurrent UTIs, and do supplements help?
Adequate fluids for people who drink little, avoiding delayed urination, and reducing irritants or spermicides linked to episodes may help. Recurrent symptoms still need diagnostic confirmation and an individual plan. Cranberry or D-mannose does not guarantee prevention or treat an acute infection.

Record episodes rather than blaming hygiene
Track symptoms, culture results and links with intercourse or new products. Recurrence does not imply poor hygiene; excessive internal washes can irritate. Do not force extra fluids if heart or kidney disease requires restriction.
Understand supplement evidence
Cranberry findings and formulations vary; suitability and interactions need review. A large 2024 primary-care trial found no preventive benefit from D-mannose in women with recurrent UTIs, so it should not be presented as a guaranteed treatment.
When to discuss a medical plan
Ongoing recurrence may warrant options tailored to age, menopause, pregnancy and cultures. Fever, flank pain or vomiting needs urgent assessment. Supplements or leftover antibiotics should not replace appropriate treatment of an acute episode.
