. Cassandra's advice about peeing and washing straight after sex is what I was told will greatly reduce the risk of getting this again (sexual activity is unfortunately a risky business for woman who are prone to UTIs). So extra hygiene measures may be called for. Constipation is an additional risk factor for UT1s as well. It's all about preventing certain bacteria from being able to travel through the urinary tract (which is always more easier in female anatomy). I wish there was some sure-proof way to guard against this nuisance. If you find some non-antibiotic way of keeping this at bay, please post your findings here. Many of us sure could do with this advice.
