Overactive bladder: symptoms, causes, treatment and which doctor
Why you keep rushing to the toilet, what causes an overactive bladder, the tests, bladder training and medicines that help, and when to see a urologist.
What overactive bladder is
Overactive bladder is a common problem in which the bladder squeezes suddenly, before it is full, giving a strong urge to pass urine that is hard to put off. People with it often need to rush to the toilet many times a day and night, and some leak urine before they get there.
It is more common with age and affects both women and men, but it is not a normal or unavoidable part of getting older. Many people in India put up with it for years out of embarrassment — planning every outing around toilets, avoiding travel, temple visits or long meetings, and drinking less water. Effective treatment is available, and the first steps are simple and do not involve medicines.
Symptoms
- Urgency — a sudden, strong need to pass urine that is difficult to delay. This is the key symptom
- Frequent urination — usually eight or more times in a day, often passing only small amounts
- Waking at night to urinate, two or more times (nocturia)
- Urge incontinence — leaking urine with or soon after the urge, before reaching the toilet
This is different from stress incontinence, where urine leaks with coughing, sneezing, laughing or lifting because the pelvic floor is weak. Many women have both, called mixed incontinence. Read more about urinary incontinence.
Burning, pain, fever, blood in the urine or cloudy, smelly urine are not typical of overactive bladder and suggest an infection or another problem that needs checking.
Causes and risk factors
Often no single cause is found; the bladder muscle simply becomes overactive. Several things make it more likely or make symptoms worse:
- Ageing, and the hormonal changes after menopause in women
- An enlarged prostate in men, which can irritate the bladder — see enlarged prostate (BPH)
- Conditions affecting the nerves that control the bladder, such as stroke, Parkinson's disease, multiple sclerosis, spinal problems and nerve damage from diabetes
- Poorly controlled diabetes, which makes the body produce more urine
- Tea, coffee, colas, energy drinks and alcohol, which irritate the bladder or increase urine
- Constipation, which presses on the bladder
- Excess body weight
- Some medicines, such as water tablets (diuretics)
A urinary tract infection, a bladder stone, and, rarely, a bladder tumour can cause similar symptoms, which is why a doctor will want to rule these out first.
How it is diagnosed
The doctor will ask about your symptoms, fluid intake, bowel habits, pregnancies and deliveries, other illnesses and medicines, and will examine your abdomen. Women may have a pelvic examination, and men a prostate examination. Common tests are:
- Urine test — to look for infection, blood or sugar
- Bladder diary — you record what you drink, when you pass urine, how much, and any leaks, usually for three days. It is one of the most useful tools, and often shows simple things to change
- Bladder ultrasound — to check how much urine is left after you have passed urine, and to look at the kidneys, bladder and prostate
- Urodynamic tests — pressure measurements of the bladder as it fills and empties, done at a specialist centre when the diagnosis is unclear or before surgery or advanced treatments
- A camera test of the bladder (cystoscopy) if there is blood in the urine or another reason to look inside
Treatment
Treatment usually starts with lifestyle changes and bladder training, which help a large number of people. Medicines and specialist treatments are added if these are not enough.
First steps
- Bladder training — gradually stretching the time between toilet visits. When the urge comes, stand or sit still, squeeze the pelvic floor muscles and wait for the urge to pass before walking calmly to the toilet. Over several weeks, the bladder learns to hold more
- Pelvic floor exercises — regular squeezing of the muscles you would use to stop passing urine. They help control urgency and leaks; a physiotherapist trained in pelvic health can check you are doing them correctly
- Drink a sensible amount of fluid spread through the day. Cutting down too much makes urine concentrated, which irritates the bladder and can cause constipation and kidney stones
- Cut down on tea, coffee, colas, energy drinks and alcohol, and drink less in the two hours before bed
- Treat constipation, lose excess weight and stop smoking
Medicines
Bladder-relaxing medicines calm the bladder muscle and reduce urgency. There are two main groups: anticholinergic (antimuscarinic) medicines and beta-3 agonists. Anticholinergics can cause dry mouth, constipation and blurred vision, and in older people some may affect memory and thinking, so doctors choose carefully. They take a few weeks to show their full effect. Women after menopause may be offered vaginal oestrogen.
Specialist treatments
- Botulinum toxin injections into the bladder wall through a cystoscope, which relax the muscle for several months and can be repeated. Some people temporarily cannot empty the bladder fully afterwards and need to use a catheter
- Nerve stimulation — mild electrical stimulation of the nerves that control the bladder, either through a fine needle near the ankle in a series of clinic sessions, or with a small implanted device
- Major bladder surgery is rarely needed and is reserved for severe cases that have not responded to anything else
Living with an overactive bladder
- Keep a bladder diary from time to time to see what helps and what makes things worse
- Wear clothing that is easy to undo quickly
- Use absorbent pads designed for urine, not period pads, while treatment takes effect
- Plan toilet stops on long journeys, but try not to go just in case all the time, as this can make urgency worse
- For older adults, a bedside commode or a clear, lit path to the toilet at night reduces the risk of falls
When to seek urgent help
Call 112 or 108, or go to the nearest emergency department, if you:
- Cannot pass urine at all, with a painful, swollen lower tummy
- Have sudden loss of bladder or bowel control with numbness around the back passage or genitals, or new weakness in the legs — this can be a sign of pressure on the spinal nerves
- Have fever, shivering and pain in the back or side along with urinary symptoms
- Pass a lot of blood or clots in the urine
See a doctor soon, rather than urgently, for any blood in the urine, burning or pain, or bladder symptoms that start suddenly or keep getting worse.
Which doctor to see
A general physician can rule out infection and diabetes and start bladder training. A urologist is the specialist for overactive bladder, especially in men with prostate symptoms, when there is blood in the urine, or when first treatments have not worked. Women may also see a gynaecologist, particularly one with an interest in urogynaecology, and a pelvic health physiotherapist can teach pelvic floor exercises. Older adults with several conditions and medicines may benefit from a geriatrician.
You can find urologists in Bengaluru or gynaecologists in Bengaluru on The Doctor Index, each with a registration you can check.
Questions to ask at your appointment
- Is this overactive bladder, or could something else be causing it?
- How much should I be drinking each day?
- Can someone teach me bladder training and pelvic floor exercises?
- What side effects should I expect from the medicine, and how long before it works?
- If these do not help, what are the next options?
Common questions
Questions people ask
- Should I drink less water if I have an overactive bladder?
- Not too much less. Drinking very little makes urine concentrated, which can irritate the bladder and worsen urgency, and it raises the risk of constipation, infections and kidney stones. Spread a sensible amount through the day, cut down on tea, coffee and alcohol, and drink less just before bed.
- Is overactive bladder a normal part of ageing?
- It becomes more common with age, but it is not something you simply have to accept. Bladder training, pelvic floor exercises, lifestyle changes and medicines help many older adults. Treating it can also reduce night-time falls and improve sleep and confidence.
- Can men get an overactive bladder?
- Yes. In men it often occurs alongside an enlarged prostate, which can also cause a weak stream and difficulty emptying. Because treatments differ, men with bladder symptoms should be assessed by a doctor, often a urologist, before starting medicines.
- Is surgery needed for overactive bladder?
- Rarely. Most people improve with bladder training, lifestyle changes and medicines. For those who do not, bladder injections and nerve stimulation are options before any major surgery. Surgery for stress leakage is a different matter and does not treat urgency.
This condition is usually assessed by a urologist. Every profile shows the doctor’s registration and what has been checked.
