What are the types of urinary incontinence?
The NHS names five types: stress, urge, mixed, overflow and total, and most women who leak have stress, urge or the two together. Urinary incontinence itself just means passing urine without meaning to. The NHS says it’s thought to affect millions of people and is common and treatable.
| Type | What triggers the leak | How much leaks | Timing | First-line NHS treatment |
|---|---|---|---|---|
| Stress | Cough, sneeze, laugh, lift, exercise | Small amounts | At the moment of pressure | Supervised pelvic floor training, at least 3 months |
| Urge | Sudden strong need to pee; running water, standing up, arriving home | Can be large | Seconds after the urge, day or night | Bladder training, at least 6 weeks |
| Mixed | Both of the above | Varies | Both patterns | Treat the dominant symptom; combine both approaches |
| Overflow | Bladder never fully empties | Frequent dribbles | Constant, feels full after going | Medical assessment of the cause |
| Total | Bladder can’t store urine | Constant or frequent large leaks | All the time | Medical assessment of the cause |
The British Association of Urological Surgeons adds a few more labels you may hear, such as functional incontinence (you can’t reach a toilet in time because of mobility or confusion) and post-micturition dribble (a few drops after you’ve finished). For most people, the five NHS types are the ones that matter.
What is stress incontinence?
Stress incontinence is leaking when your bladder is put under sudden pressure, and it has nothing to do with emotional stress. The “stress” is physical: a cough, a sneeze, a laugh, lifting a toddler, a star jump, a run. The pelvic floor and the ring of muscle that closes the urethra can’t hold against the squeeze, and a little urine escapes.
The leaks are small, a few drops to a dampened gusset, and they happen at the moment of pressure rather than after a warning.
The Bladder & Bowel Community says about 9 million people in the UK have some form of stress incontinence and around a third of UK women have it, though it doesn’t cite a source for those figures. A survey of 1,415 women at one UK GP practice, published in the journal Primary Health Care Research & Development, found 24 per cent reported stress incontinence, with the peak at ages 35 to 44.
What is urge incontinence?
Urge incontinence is a sudden, intense need to pass urine that you can’t put off, with the leak arriving seconds later. The NHS says it’s often part of overactive bladder, so you may also find yourself going far more than before, including several times a night.
Common triggers are changing position, hearing or touching running water, and the “latch-key” moment the Bladder & Bowel Community describes: you’re fine all the way home, then the key goes in the door and the urge hits. Leaks may also happen during sex.
Urge leaks can be large, because the bladder is emptying rather than dribbling. In the same GP practice survey, 7 per cent of women reported urge incontinence or overactive bladder alone, and 20 per cent reported mixed symptoms, which rose with age to peak at 55 to 64.
How can you tell which one you have?
Ask yourself two questions: do you leak when you cough, sneeze, laugh or lift, or do you leak on the way to the toilet after a sudden urge? Leaks with pressure point to stress incontinence. Leaks after an urge you couldn’t hold point to urge incontinence. Both answers mean mixed.
Your GP will ask the same questions and more, and will probably ask you to keep a bladder diary for at least three days: when you drink, what you drink, when you pee, how much, and when you leak. The Bladder & Bowel Community suggests starting one before your appointment so you arrive with the pattern already written down.
Two more clues from the NHS symptoms page. Waking at night to pee points to urge or overactive bladder. Feeling full straight after you’ve been, or dribbling without any urge, points to overflow and needs checking.
Self-checking helps you describe the problem to your GP. It doesn’t replace the examination.

Stress leaks come from a weakened or damaged pelvic floor or urethral sphincter, while urge leaks have a different set of triggers, and the NHS lists separate causes for each.
For stress incontinence the NHS names: damage during vaginal childbirth; extra pressure on the tummy from pregnancy or obesity; damage from surgery such as a hysterectomy; neurological conditions such as Parkinson’s or multiple sclerosis; connective tissue disorders; and certain medicines. The Bladder & Bowel Community adds the hormonal changes of menopause, and the NHS menopause page lists needing to pee more, not being able to control when you pee, and more UTI-like symptoms among menopause and perimenopause symptoms.
For urge incontinence the NHS names: too much alcohol or caffeine; drinking too little, so concentrated urine irritates the bladder lining; constipation; urinary tract infections or, rarely, bladder tumours; neurological conditions; and some medicines.
Medicines the NHS says can cause or worsen leaks include ACE inhibitors, diuretics (water tablets), some antidepressants, HRT and sedatives. Don’t stop any of them without talking to the prescriber.
Risk rises with age (the NHS says it’s common in middle age and more common still over 80) and with a family history.
What is mixed incontinence, and what about overflow and total?
Mixed incontinence is stress and urge together; overflow and total incontinence are rarer and need a medical assessment to find the cause. In the GP practice survey above, mixed symptoms were reported by more women than urge symptoms alone, and they peaked at ages 55 to 64.
With mixed incontinence the GP will ask which symptom bothers you most and start there, combining pelvic floor training with bladder training.
Overflow incontinence (the NHS also calls it chronic urinary retention) means the bladder never empties properly, so it dribbles frequently and feels full even after you’ve been. The NHS lists an enlarged prostate, bladder stones, constipation and nerve damage among causes. A GP may arrange a scan to measure how much urine is left after you pee.
Total incontinence means the bladder can’t store urine at all, so you leak constantly or have frequent large leaks. The NHS links it to a bladder problem present from birth, a spinal injury, or a fistula (a small channel between the bladder and a nearby organ). It needs a specialist.
How are stress and urge incontinence treated on the NHS?
NICE sets out the first-line pair clearly: supervised pelvic floor muscle training for at least three months for stress or mixed incontinence, and bladder training for at least six weeks for urge or mixed incontinence. Both come before any medicine or surgery.
For stress incontinence the NHS dose is at least eight pelvic floor squeezes, at least three times a day, for at least three months, and to carry on if it’s helping. A continence physio or specialist nurse can check you’re squeezing the right muscles, and the Squeezy app, designed by NHS pelvic health physiotherapists, gives reminders and a log. If training alone isn’t enough, the medicine duloxetine may be offered and reviewed after two to four weeks, and surgery such as a sling is a later option once conservative treatment has been tried. NICE says HRT isn’t a treatment for incontinence.
For urge incontinence, bladder training is a programme of at least six weeks that works on holding on for longer between toilet visits. Alongside it the NHS advises cutting caffeine (coffee has the biggest effect), cutting alcohol, treating constipation, and drinking six to eight glasses of water a day rather than restricting fluids. If that’s not enough, medicines such as oxybutynin, tolterodine or darifenacin, or the newer mirabegron and vibegron, may be prescribed, with a review after about four weeks because benefit can take that long. Botulinum toxin injections or nerve stimulation are options further down the line.
Lifestyle changes help both types: losing weight if your BMI is over 30, stopping smoking, bracing before you lift, and swapping high-impact exercise for Pilates-type work while the muscles build.
Which leak-proof pants suit each type of incontinence?
Pants manage the leak while treatment works; they don’t treat the cause, and NICE describes absorbent products as a coping strategy or an adjunct to treatment with a review at least once a year. Within that frame, the type you have shapes what to wear.
Frequent small stress leaks suit a lighter everyday style. Occasional larger urge leaks may need a heavier style, because the volume arrives in one go. Mixed incontinence is a case for having both in the drawer.
Annahitah grades its pants Light, Medium, Heavy and Super Heavy, describes bladder-leak coverage as “from dribbles to heavier leaks”, and publishes no ml figure. Light thongs such as Venus, Nirvana and Eden sit under gym leggings for exercise-triggered stress leaks. Heavy styles such as Serendipity and Lilah cover regular daytime leaks. Super Heavy styles such as Shanti, Odessa, Athena and Valentina are the ones the site describes as designed for overnight wear, and the ones to look at for urge leaks that catch you out. Once your GP has confirmed the type and you know your pattern, a pair or two of leak-proof pants matched to it can cover you while the exercises do their work.

When should you see a GP about leaking urine?
The NHS says to see a GP if you have any type of urinary incontinence, and it adds that the problem is common and treatable. The Bladder & Bowel Community’s advice is the same: don’t put up with it, and ask for a referral.
Some signs need urgent help, not a routine appointment:
- Blood in your urine, even once, even a small amount, even if you’re not sure. Pink, red or dark brown urine means an urgent GP appointment or NHS 111. It can be a sign of cancer.
- UTI symptoms: burning when you pee, going more than usual, cloudy or smelly urine, pain low in your tummy or back, or a temperature. Women aged 16 to 64 can see a pharmacist first; get urgent GP or 111 help if you’re over 65, pregnant, diabetic, in pain, passing blood, not improving after 48 hours, or having repeated infections (two in six months or three in a year).
- Leaking that’s new or suddenly worse in an older person, which the NHS says can itself be a UTI sign, especially with confusion.
- Confusion or drowsiness with any of the above: 999 or A&E.
NICE lists reasons your GP should refer you to a specialist: persistent bladder or urethral pain, a bladder you can still feel after emptying, a lump in your pelvis, bowel leakage as well as bladder leakage, numbness or weakness that could point to a nerve condition, difficulty emptying, a suspected fistula, or past pelvic surgery, cancer surgery or radiotherapy.
