You definitely need a urologist
and gynecological evaluation.
1.First I would like to ask you of any history of unprotected sexual activity or any history of sexually transmitted disease
. If that's the case, it could give rise to chlamydia or gonorrhea
which could be persistent unless you treat it.I would advise gynecologist evaluation for that.
2. Diabetes could give rise to recurrent UTI. You need to test your blood sugar levels
3.There is also something called Diabetes insipidus
which is due to a.hormones in the brain or b.some problems in kidney or c. as a result of stress. It could also be found out by blood testing under specific test conditions.
4.Any birth defects in your urinary tract
can make u go often.
5. There is something called spasmodic bladder which could cause you to urinate more often without any obvious structural defect. It can be treated as well.
