Cystitis is inflammation of the bladder wall, almost always because gut bacteria have found their way inside. It is easy to recognise: stinging when you pass urine, an urge every quarter of an hour, and the feeling that the bladder never quite empties. In women the urethra is short and opens close to the back passage, so cystitis is an ordinary event; in men, in children and in pregnancy it is uncommon and always calls for an explanation. Most episodes are over within a few days, but the same infection has a sequel — it climbs towards the kidney — and those warning signs are worth knowing in advance.
What it feels like
An adult usually describes it like this:
- burning, stinging or a prickling sensation, especially at the end of passing urine;
- an urge every ten or fifteen minutes, with only a few drops each time;
- a dragging heaviness low in the abdomen, above the pubic bone;
- urine that is cloudy, dark and strong-smelling, sometimes tinged pink;
- getting up at night in someone who used to sleep through.
Ordinary cystitis brings either no fever at all or a mild one, and general health is barely dented: people carry on with the day and mostly resent the endless trips to the toilet.
Small children look quite different, because they do not complain of stinging. What should prompt attention is a high temperature with no cough or runny nose, vomiting, refusing food, listlessness or unusual irritability, sharply smelling urine, and daytime wetting returning in a child who was reliably dry.
In older people, particularly those with dementia, and in anyone living with a urinary catheter, the first thing to change is behaviour rather than pain: sudden confusion, agitation, unusual drowsiness, falls out of nowhere, shivering. One caution belongs here. Bacteria turn up in an older person's urine often enough without any illness at all, and on their own they are not a reason for antibiotics. Symptoms are treated, not laboratory results.
When waiting is the wrong choice
Same-day medical attention is needed if the usual picture gains any of the following:
- a temperature above 38 degrees, or shivering and chills;
- pain in the lower back or in one flank, under the ribs;
- nausea and vomiting;
- blood you can see in the urine;
- nothing changing after two or three days, or getting worse while already on antibiotics.
The first three describe infection in the kidney, reached by bacteria climbing up from the bladder. Delay is also unwise for pregnant women, men, children, anyone with stones, a single or transplanted kidney, diabetes, or medicines that damp down the immune system.
Call an ambulance — 112 is the single European number — for signs of sepsis: confusion or slurred, muddled speech, strange drowsiness, fast shallow breathing, skin that is cold, pale or mottled, a very high temperature or, conversely, one below normal, and many hours with no urine passed at all. A urine infection that turns systemic moves within hours, and it is not something to sit on until morning.
Where the bacteria come from
In the overwhelming majority of cases it is Escherichia coli and its neighbours from the bowel: they reach the urethra from outside and travel up. Everything that makes an episode more likely follows from that:
- sex, the commonest trigger in younger women;
- spermicides, including those on condoms and those used with a diaphragm, because they disturb the vaginal flora;
- the menopause, with thinner lining and fewer lactobacilli;
- anything that stops the bladder emptying fully: an enlarged prostate, prolapse of the vaginal walls, neurological illness, a habit of holding on for hours;
- stones and any obstruction to the flow of urine;
- a urinary catheter, with risk rising for every day it stays in;
- diabetes with high blood sugar, pregnancy, a weakened immune system;
- previous bouts of cystitis: one episode raises the chance of the next.
Getting cold, contrary to a firmly held belief, does not start the infection — bacteria do not come from a chilly bench. It can sharpen the urge in someone whose bladder is already inflamed, which is how it earned its reputation.
What you can do yourself
For a mild episode in a woman who is not pregnant, it is reasonable to give the body a day or two. Simple measures help:
- drinking somewhat more than usual, enough to keep the urine pale, without forcing litres of water down;
- an over-the-counter painkiller: paracetamol is the gentler option, anti-inflammatory tablets dull the stinging better but are avoided if you are dehydrated or have kidney disease;
- warmth over the lower abdomen from a hot water bottle;
- putting sex aside for a few days;
- dropping what irritates the bladder further: coffee, alcohol, acidic juices, a lot of sugar;
- not holding on when the urge comes, and emptying the bladder fully rather than in a hurry.
What not to do: finish off the antibiotic left over from last time, or borrow one from a friend. A course taken at random is usually the wrong drug for the wrong length of time, while reliably breeding resistant bacteria — so next time the doctor has fewer options left.
Cranberry products and D-mannose come up constantly. They do not cure an episode that has already begun; that much is firmly settled. For preventing repeats the evidence is weak and inconsistent: cranberry does seem to help some women, but the effect is modest and the juices carry a lot of sugar. Cranberry is not combined with warfarin.
How a doctor helps
The conversation and the symptoms are usually enough: with a typical picture in a woman, a urine test adds nothing to the decision. A dipstick or a culture is kept for cases that are not typical — pregnancy, a man, a child, repeat episodes, a course that failed, suspicion of the kidney.
From there, three routes. The first is a short antibiotic course, normally a few days; which drug depends on the country, because resistance patterns differ from place to place and first choices differ with them. The second is a delayed prescription: handed over straight away, with the advice to wait a couple of days and start only if things do not settle by themselves. The third is pain relief alone, when symptoms are mild and the person would rather sit it out.
Pregnant women are always treated, and without a waiting period — including when bacteria show up on a test and there are no symptoms at all, because in pregnancy that finding opens the way to a kidney infection and to early labour. Some of the usual antibiotics are not used in pregnancy, so self-treatment is off the table. Children are also started promptly, since infection reaches their kidneys more readily.
When cystitis keeps coming back
Recurrent cystitis means two episodes in six months, or three or more in a year. At that point a doctor usually suggests looking deeper: a culture with sensitivity testing, an ultrasound scan of the kidneys and bladder, a measurement of urine left behind after voiding and, for women past the menopause, a gynaecological assessment.
What genuinely cuts the frequency: local oestrogen as a cream or pessary after the menopause, a single antibiotic dose taken straight after sex when episodes are clearly linked to it, and long-term low-dose preventive treatment — the last of these prescribed reluctantly and never indefinitely, because it is paid for in resistance. Non-antibiotic preventive options also exist and are chosen case by case.
One situation deserves its own paragraph: symptoms are there, yet cultures come back clean time after time and antibiotics do nothing. That is a signal to reconsider the diagnosis rather than raise the dose. Bladder pain syndrome behaves this way, so does a thinned, atrophic lining, a stone sitting low in the ureter and, in men, the prostate.
And something that gets discussed less often. Visible blood in the urine, especially in a smoker or in anyone over fifty, calls for the bladder to be examined even if infection was confirmed and the symptoms have gone: a tumour occasionally hides behind the label of cystitis that will not end. Stubborn symptoms in a man with no bacterial growth, blood that persists, unexplained weight loss — all of that goes to a urologist rather than into another course of tablets.
What lowers the chance of a repeat
It is worth being straightforward: the everyday advice is not all backed equally. The firmest evidence is for fluids — drinking enough noticeably reduces the number of episodes in women who used to drink little. The rest is harmless, cheap and sensible, but unproven:
- washing with plain water, no perfumed soaps, bubble baths or scented gels;
- wiping from front to back;
- passing urine soon after sex;
- swapping spermicide for a lubricant without it, or discussing a different contraceptive;
- choosing a shower over a bath;
- changing pads and incontinence products promptly and keeping the skin dry;
- not putting off a trip to the toilet, and not rushing it.
If a catheter is permanent, the conversation to have with the medical team is about its care and how often it is changed; that matters far more than any household detail.
Online consultation
Typical cystitis in an adult woman is exactly the kind of problem that works well remotely. The doctor will ask what hurts and for how long, whether there were earlier episodes and how they ended, whether there is fever or back pain, and what you have already taken; from that comes the decision on whether an antibiotic is needed now, whether waiting is reasonable, and which test is worth doing. It is also a convenient way to deal with what drags on for months: why the episodes repeat, how to use local oestrogen, whether prevention is worth trying, and which specialist to see when the cultures stay clean. The signs listed above are not handled through a screen: with fever, flank pain or visible blood you need to be examined in person the same day, and with confusion you need an ambulance.
