Understanding the Different Types of Incontinence
The five types of urinary incontinence explained
There are five types of urinary incontinence: stress, urge, overflow, functional and mixed. That's how healthdirect sets out the types of incontinence that affect the bladder, each with different causes and treatments. Stress incontinence involves leaks during physical activity. Urge incontinence is a sudden, intense need to go.
Overflow means the bladder doesn't empty fully. Functional incontinence occurs when a physical or cognitive barrier prevents reaching the toilet. Mixed incontinence is a combination of stress and urge incontinence.
This guide covers leaking urine. Bowel leakage is a separate condition, and one to raise with your GP. For the bigger picture, start with our guide to living well with incontinence.
What is stress incontinence?
Stress incontinence has nothing to do with emotional stress. It happens when physical pressure on the bladder causes a small leak. It can be set off by coughing, sneezing, laughing, lifting something heavy or exercising. The underlying cause is usually a weakened pelvic floor, the group of muscles that supports the bladder and helps control the flow of urine.
This type is more common in women, particularly after pregnancy, childbirth, or menopause. Men can experience it too, especially after prostate surgery. The leaks are usually small, but they're unpredictable, which is what makes them frustrating.
Pelvic floor exercises are one of the most effective ways to manage stress incontinence, and a continence physiotherapist can put together a program for your situation.
Stress incontinence vs urge incontinence
Where stress incontinence involves small leaks during physical activity, urge incontinence is a different experience altogether. It's a sudden, intense need to go to the toilet, followed by an involuntary loss of urine before you can get there. Some people describe it as a feeling that comes on with almost no warning.
The cause is typically an overactive bladder muscle that contracts when it shouldn't. This can happen due to nerve damage, infection, or conditions like diabetes and Parkinson's disease. In many cases, there's no single identifiable cause.
Bladder retraining, which involves gradually increasing the time between toilet visits, is one of the first things a healthcare professional will suggest. The RACGP's aged care clinical guide recommends it for urge incontinence in people with good cognitive function. If you're caring for someone with memory or thinking problems, ask their GP or continence nurse what will suit them instead.

What is overflow incontinence?
Overflow incontinence happens when the bladder doesn't empty completely. Instead of one large loss, you'll notice frequent dribbling or a constant small leak. It can feel like you never quite finish going to the toilet, or that your bladder is always partly full.
The RACGP's aged care clinical guide lists an enlarged prostate in men as one thing that can partly block the flow of urine and cause it. Other causes include nerve damage from diabetes, spinal injuries, or certain medications that affect bladder function.
Because overflow incontinence involves a medical issue with bladder emptying, it's important to see your GP sooner rather than later. Treatment often focuses on addressing the underlying cause. If your bladder feels full but you can't pass urine at all, don't wait for an appointment: the urgent steps are under When to get help, below. For a routine appointment, a product designed for ongoing light leakage can help keep you comfortable in the meantime, and your GP or continence nurse can advise on the right level of protection.
Functional incontinence in elderly people
Functional incontinence is different from the other types because the bladder itself may be working normally. The issue is that something else prevents the person from getting to the toilet in time. Reduced mobility, arthritis, cognitive conditions like dementia, or even the layout of a home can all create barriers.
A person with functional incontinence might recognise the need to go but simply can't move fast enough. Or they might not remember where the bathroom is.
For carers, the priority is removing barriers where you can: keep pathways clear, use clothing that's easy to remove quickly, and consider a regular toileting routine.
Mixed incontinence explained
Mixed incontinence is a combination of stress and urge incontinence, which is how both healthdirect and the RACGP define it. That means you might have small leaks during physical activity and sudden urgent episodes at other times. This type is most common in older women, healthdirect notes.
If your symptoms don't fit neatly into one type, tell your GP. The RACGP's aged care clinical guide lists an unclear type of incontinence as one reason for a GP to consider referral to a specialist for further tests.
A GP or continence specialist can help work out which type is dominant, and that guides the treatment plan.
Which type might I have?
If you're reading this trying to work out what's going on with your own body, these questions can help you narrow it down before you see your GP.
Do your leaks happen when you cough, sneeze, laugh, or lift something heavy? That pattern points to stress incontinence. The leak is triggered by physical pressure on your bladder, and it's usually a small amount.
Do you get a sudden, intense urge to go, and sometimes don't make it in time? That's more likely urge incontinence. The key sign is how quickly the need comes on, often with very little warning.
Do you feel like your bladder never fully empties, with frequent dribbling throughout the day? That sounds like overflow incontinence, and it's worth seeing your GP promptly because it usually has an underlying medical cause. If you can't pass urine at all, that is urgent: see When to get help, below.
Does the person you care for know they need to go but can't get to the toilet in time? If mobility, cognition, or the physical environment is the barrier rather than the bladder itself, that's functional incontinence.
Do you recognise more than one of these patterns? Leaks with physical pressure plus sudden urgent episodes is mixed incontinence, the combination of stress and urge. If your pattern is a different mix, or doesn't match any of these, describe it to your GP as it is. An unclear type is something they can look into further.
These questions are a starting point, not a diagnosis. Only a GP or continence specialist can confirm what type of incontinence you're dealing with. But a clear description of your symptoms makes that appointment much easier.
When to get help
Some symptoms shouldn't wait.
Can't pass urine at all. If your bladder feels full but you can't pass urine at all, see your doctor immediately, or go to the emergency department if your doctor isn't available. That's the advice in healthdirect's urinary retention guidance.
Blood in your urine. If you notice bright red blood in your urine or your urine has turned pink, red or brown, see your doctor straight away. If there is a lot of blood in your urine or there are blood clots, call triple zero (000) for an ambulance, and seek urgent care if you have blood in your urine along with abdominal pain, back or flank pain, fever, or nausea and vomiting. All three steps come from healthdirect's guidance on blood in urine.
Back pain with new loss of feeling or control. Back pain with new loss of feeling or movement in your limbs, or new problems controlling your bladder or bowels, needs triple zero (000). For back pain with these signs, healthdirect's back pain guidance says to call 000 and ask for an ambulance.
Back pain with a fever. If you have a fever or are unwell along with back pain, healthdirect's back pain guidance says to call triple zero (000) or go to your nearest emergency department.
Back pain with bladder or bowel changes. If you have back pain with symptoms such as muscle weakness or numbness in your legs, or changes to your bladder or bowel function (such as incontinence or urinary retention), healthdirect's back pain guidance says to call triple zero (000) or go to your nearest emergency department.
Signs of a kidney infection. Fever, lower back and side pain, diarrhoea, and nausea and vomiting are among the signs of a kidney infection listed in healthdirect's urinary tract infection guidance. It says to see your doctor straight away if you have symptoms of a kidney infection.
Signs of a UTI. The same page lists pain, stinging or a burning feeling when urinating, smelly or cloudy urine, and needing to go often or at night among the symptoms of a UTI. See your doctor as soon as possible if you have any symptoms of a UTI, it says. It also notes that older people with a UTI can sometimes become confused or get delirium.
For everything else, healthdirect's guidance is simpler still: see your doctor if you are having trouble controlling your bladder. There's no threshold you have to reach first.
What to do next
If you've read through these descriptions and recognised what you or someone you care for is experiencing, that's a solid first step. The next one is talking to your GP or calling the National Continence Helpline on 1800 33 00 66 for free, confidential advice from a nurse continence specialist.
Incontinence is manageable. The right combination of professional advice, practical strategies, and the right product can make a genuine difference to daily life.
Some incontinence is also temporary. UTIs, certain medications, and even severe constipation can cause leaks that stop once the underlying issue is treated. For a complete guide to managing incontinence day to day, visit our incontinence management guide.
