What is urge incontinence?
- Urgency is a symptom where you get a sudden urgent desire to pass urine. You are not able to put off going to the toilet.
- Urge incontinence is when urine leaks before you get to the toilet when you have 'urgency'.
Urgency and urge incontinence are sometimes called an unstable or overactive bladder, or detrusor instability. (Detrusor is the medical name for the bladder muscle.)
If you have urgency or urge incontinence, you also tend to pass urine more often than normal (this is called 'frequency'). Sometimes this is several times during the night as well as many times during the day. Some women also find they leak urine during sex, especially during orgasm.
How common is urge incontinence?
Urge incontinence is the second commonest cause of incontinence. About 3 in 10 cases of incontinence are due to urge incontinence. It can occur at any age, but commonly first starts in early adult life. Women are more commonly affected than men.
(The most common type of incontinence is
stress incontinence which is dealt with in a separate page. Very briefly, stress incontinence occurs when the pressure in the bladder becomes too great for the bladder outlet to withstand. Urine tends to leak most when you cough, laugh, or when you exercise. Some people have both stress incontinence and urge incontinence.)
There are other less common causes of incontinence. Note: you should always see your doctor if you develop incontinence. There are different causes of incontinence, and each cause has different treatments. Your doctor will assess you to determine cause and advise on possible treatment options. See separate page called '
Urinary Incontinence' for a general overview. The rest of this page is only about urge incontinence.
What causes urge incontinence?
The cause is not fully understood. The bladder muscle seems to become overactive and contract (squeeze) when you don't want it to.
Normally, the bladder muscle (detrusor) is relaxed as the bladder gradually fills up. Normally, as the bladder is gradually stretched, we get a feeling of wanting to pass urine when the bladder is about half full. Most people can hold on quite easily for some time after this initial feeling until a convenient time to go to the toilet. However, in people with overactive bladder and urge incontinence, the bladder muscle seems to give wrong messages to the brain. The bladder may feel fuller than it actually is. The bladder contracts too early when the bladder is not very full, and not when you want it to. This can make you suddenly need the toilet. In effect, you have much less control over when your bladder contracts to pass urine.
In most cases, the reason why an overactive bladder develops is not known. This is called 'overactive bladder syndrome'. Symptoms may get worse at times of stress. Symptoms may also be made worse by caffeine in tea, coffee, cola, etc, and by alcohol (see below).
In some cases, symptoms of an overactive bladder develop as a complication of a nerve-related disease such as following a stroke, or with Parkinson's disease. Also, similar symptoms may occur if you have a urine infection or an enlarged prostate. These conditions are not classed as overactive bladder syndrome as they have a known cause.
What are the treatments for urge incontinence?
- Some general lifestyle measures may help.
- Bladder retraining is usually the main treatment. This can work well in up to half of cases.
- Medication may be advised instead of, or in addition to, bladder retraining.
- Pelvic floor exercises may also be advised in some cases.
- Surgery is a last resort and rarely used to treat urge incontinence.
Some general lifestyle measures which may help
- Getting to the toilet. Make this as easy as possible. If you have difficulty getting about, consider special adaptations like a handrail or a raised seat in your toilet. Sometimes a commode in the bedroom makes life much easier.
- Caffeine. This is in tea, coffee, cola, and is part of some painkiller tablets. Caffeine has a diuretic effect (will make urine form more often). Caffeine may also directly stimulate the bladder to make urgency symptoms worse. It may be worth trying without caffeine for a week or so to see if symptoms improve. If symptoms do improve, you do not need to give up caffeine. However, you may wish to limit the times that you have a caffeine-containing drink. Also, you will know to be near to a toilet whenever you have caffeine.
- Alcohol. In some people, alcohol may make symptoms worse. The same advice applies as with caffeine drinks.
- Drink normal quantities of fluids. It may seem sensible to cut back on the amount that you drink so as the bladder does not fill so quickly. However, this can make symptoms worse as the urine becomes more concentrated which may irritate the bladder muscle. Aim to drink normal quantities of fluids each day. This is usually about two litres of fluid per day - about 6-8 cups of fluid, and more in hot climates and hot weather.
- Go to the toilet only when you need to. Some people get into the habit of going to the toilet more often than they need. They may go when their bladder only has a small amount of urine so as "not to be caught short". This again may sound sensible as some people think that symptoms of urgency and urge incontinence will not develop if the bladder does not fill very much and is emptied regularly. However, again, this can make symptoms worse in the long-run. If you go to the toilet too often, the bladder becomes used to holding less urine. The bladder may then become even more sensitive and overactive at times when it is stretched a little. So, you may find that when you need to hold on a bit longer (for example, if you go out), symptoms are worse than ever.
Bladder training (sometimes called 'bladder drill')
The aim is to slowly stretch the bladder so that it can hold larger and larger volumes of urine. In time, the bladder muscle should become less overactive and you become more in control of your bladder. This means that more time can elapse between feeling the desire to pass urine, and having to get to a toilet. Leaks of urine are then less likely. A doctor, nurse, or continence advisor will explain how to do bladder training. The advice may be something like the following.
You will need to keep a diary. On the diary make a note of the times you pass urine, and the amount (volume) that you pass each time. Also make a note of the times you leak urine (are incontinent). Your doctor or nurse may have some pre-printed diary-charts for this purpose to give you. Keep an old measuring jug by the toilet so that you can measure the amount of urine you pass each time you go to the toilet.
When you first start the diary, go to the toilet as usual for 2-3 days at first. This is to get a baseline idea of how often you go to the toilet and how much urine you normally pass each time. If you have an overactive bladder you may be going to the toilet every hour or so, and only passing less than 100-200 ml each time. This will be recorded on the diary.
After the 2-3 days of finding your 'baseline', the aim is then to 'hold on' for as long as possible before each time you go to the toilet. This will seem difficult at first. For example, it you normally go to the toilet every hour, it may seem quite a struggle to last one hour and five minutes between toilet trips. When trying to hold-on, try distracting yourself. For example:
- Sitting straight on a hard seat may help.
- Try counting backwards from 100.
- Try doing some pelvic floor exercises (see below).
With time it should become easier as the bladder becomes used to holding larger amounts of urine. The idea is to gradually extend the time between toilet trips and to train your bladder to stretch more easily. It may take several weeks, but the aim is to pass urine only 5-6 times in 24 hours (about every 3-4 hours). Also, each time you pass urine you should pass much more than your baseline diary readings. (On average, people without an overactive bladder normally pass 250-350 ml each time they go to the toilet.) After several months you may find that you just get the normal feelings of needing the toilet which you can easily put off for a reasonable time until it is convenient to go.
Whilst doing bladder training, perhaps fill in the diary for a 24 hour period every week or so. This will record your progress over the months of the training period. Bladder training can be difficult, but becomes easier with time and perseverance. It works best if combined with advice and support from a continence advisor, nurse, or doctor. Make sure you drink a normal amount of fluids when you do bladder training (see above).
Medication
Medicines in the class of drugs called antimuscarinics (also called anticholinergics) can help. They include: oxybutynin, tolterodine, trospium chloride, propiverine, and solifenacin. These also come in different brand names. They work by blocking certain nerve impulses to the bladder which 'relaxes' the bladder muscle and so increases the bladder capacity.
Medication improves symptoms in some cases, but not all. The amount of improvement varies from person to person. You may have fewer toilet trips, fewer urine leaks, and less urgency. However, it is uncommon for symptoms to go completely with medication alone.
A common plan is to try a course of medication for a month or so. If it is helpful, you may be advised to continue for up to six months or so and then stop the medication to see how symptoms are without the medication. Symptoms may return after you finish a course of medication. However, if you combine a course of medication with bladder training, the long-term outlook may be better and symptoms may be less likely to return when you stop the medication.
Side-effects are quite common with these medicines, but are often minor and tolerable. Read the information sheet which comes with your medicine for a full list of possible side-effects. The most common is a dry mouth, and simply having frequent sips of water may counter this. Other common side-effects include dry eyes, constipation and blurred vision. However, the medicines have differences, and you may find that if one medicine causes troublesome side-effects, a switch to a different one may suit you better.
Pelvic floor exercises
Many people have a mixture of urge incontinence and stress incontinence. Pelvic floor exercises are the main treatment for stress incontinence. Briefly, this treatment involves exercises to strengthen the muscles that wrap underneath the bladder, uterus (womb) and rectum. For details, see separate pages called '
Stress Incontinence' and '
Pelvic Floor Exercises'.
It is not clear if pelvic floor exercises help if you just have urge incontinence without stress incontinence. However, pelvic floor exercises may help if you are doing bladder training (see above).
Continence adviser
Your GP may refer you to the local continence adviser. Continence advisors can give advice on treatments, especially about bladder training and pelvic floor exercises. If incontinence remains a problem, they can also give lots of advice on how to manage. For example, they may be able to supply various appliances and aids to help such as incontinence pads, etc.
