Is cystitis the same as a UTI?
Not quite. Cystitis means bladder inflammation. When bacteria cause it, cystitis and lower UTI are the same thing. When they do not — which is a significant minority of cases — it is still cystitis, but antibiotics will not help it.
My urine tests keep coming back clear. Am I imagining it?
No. Persistent bladder symptoms with negative cultures is a recognised clinical picture, not a psychological one. It usually means bladder pain syndrome, menopausal urogenital change, or pelvic floor dysfunction — all real, all treatable, and none of them helped by more antibiotics. Being told there is nothing wrong because a dipstick was clear is a failure of the test, not of you.
Why do I get it every time after sex?
Sex mechanically moves bacteria towards the urethra, and friction irritates the tissue. Passing urine afterwards helps. If it happens reliably, a single antibiotic dose taken after sex is far more effective and involves far less antibiotic than treating each episode — worth asking about.
Does cranberry help?
The evidence is weak for preventing bacterial infection and it does not treat an established one. In bladder pain syndrome cranberry is acidic and frequently makes symptoms worse, so it is not a good idea there.
Should I drink loads of water?
Enough to keep urine pale, but not to excess. In bladder pain syndrome, drinking large volumes fills an already irritated bladder more often and worsens things. Steady moderate intake is better than flooding.
Can men get cystitis?
Yes, though much less often — and it is never treated as routine. Cystitis in a man warrants thought about the prostate, incomplete bladder emptying or a structural cause, and always deserves a urine culture and a longer antibiotic course.
Why does it keep coming back after the menopause?
Falling oestrogen thins the tissue of the vagina and urethra and changes the protective bacteria, which causes both genuine infections and infection-like symptoms without bacteria. Vaginal oestrogen is highly effective for this, is absorbed minimally, and suits many women who cannot take systemic HRT. It is one of the most under-offered treatments in this area.
Will pelvic floor exercises help?
Only if the floor is weak. If it is overactive and tense — which is common in bladder pain syndrome — squeezing exercises make symptoms worse. This is why a proper pelvic floor physiotherapy assessment is worth having before starting exercises you found online.
