Stress incontinence is a common type of urinary incontinence that causes urine to leak when pressure is placed on the bladder. This can happen when you cough, sneeze, laugh, exercise, bend over, lift something heavy, or have sexual activity.
Despite its name, stress incontinence is not caused by emotional or mental stress. The word “stress” refers to physical pressure placed on the bladder. Stress urinary incontinence can affect women and men, although it is more common in women. Pregnancy, childbirth, menopause, aging, obesity, chronic coughing, and weakening of the pelvic floor can increase the risk. In men, prostate surgery is an important cause.
The good news is that stress incontinence is treatable. Depending on how severe the leakage is, treatment may include pelvic floor exercises, lifestyle changes, a pessary or other support device, urethral bulking injections, or surgery.
What Is Stress Incontinence?
Stress incontinence is a form of urinary incontinence in which urine leaks involuntarily when physical pressure increases inside the abdomen and puts pressure on the bladder.
Normally, the pelvic floor muscles and urinary sphincter help keep the urethra closed. When these supporting structures become weak or damaged, they may not provide enough resistance when pressure suddenly increases.
For example, coughing creates pressure that is transmitted to the bladder. If the urethra cannot remain closed properly, a small amount of urine may leak. Stress incontinence can range from occasional drops of urine to more noticeable leakage during exercise or other physical activities.
What Causes Stress Incontinence?
Stress incontinence occurs when the muscles and tissues responsible for supporting the bladder and closing the urethra become weakened or damaged. The pelvic floor muscles support pelvic organs, including the bladder. The urinary sphincter helps control the release of urine. When these structures do not work effectively, activities that increase abdominal pressure can cause urine to escape.
Pregnancy and Childbirth
Pregnancy can put additional pressure on the pelvic floor.
Vaginal childbirth can also stretch or damage pelvic floor muscles, connective tissue, and nerves. Stress incontinence may begin shortly after childbirth or develop years later. Having multiple pregnancies or vaginal deliveries can increase the likelihood of urinary incontinence.
Menopause
Hormonal changes associated with menopause can contribute to changes in the tissues supporting the bladder and urethra. Menopause is recognized as a factor associated with bladder control problems in women.
Aging
Stress incontinence can occur at any age, but the risk may increase as muscles and supporting tissues become weaker with age. Importantly, urinary incontinence is not an unavoidable part of normal aging, and treatment is available.
Obesity
Extra body weight can increase pressure on the bladder and pelvic floor. Losing excess weight may reduce urine leakage in people who are overweight or obese.
Chronic Coughing
Repeated coughing can repeatedly increase pressure on the bladder and pelvic floor. Long-term smoking, respiratory disease, or other conditions that cause chronic coughing may therefore contribute to stress incontinence.
Prostate Surgery
In men, stress incontinence commonly develops after prostate surgery, particularly surgery performed for prostate cancer. Surgery can affect the urinary sphincter and surrounding structures, resulting in temporary or persistent urine leakage.
Stress Incontinence in Women
Stress incontinence is particularly common in women because pregnancy, childbirth, pelvic floor changes, and menopause can affect the structures supporting the bladder and urethra.
Women may notice urine leakage while:
- Sneezing
- Coughing
- Laughing
- Running
- Exercising
- Jumping
- Lifting
- Getting out of a chair
- During sexual activity
Some women experience only a few drops, while others may have more significant leakage during physical activity.
Pelvic floor muscle training is commonly recommended as an initial treatment approach.
Stress Incontinence in Men
Stress incontinence is less common in men than in women.

One of the most important causes is treatment for prostate cancer, especially prostatectomy. Prostate surgery can weaken or affect the urinary sphincter, which may lead to urine leakage during coughing, lifting, exercise, or other activities. Some men improve gradually after prostate surgery, while others may need pelvic floor rehabilitation, devices, medications for other types of incontinence, or surgical treatment depending on the cause and severity.
Symptoms of Stress Incontinence
The main symptom is involuntary urine leakage during physical activity or pressure.
You may notice leakage when you:
Cough or Sneeze
A sudden increase in abdominal pressure can push urine out through the urethra.
Laugh
Strong laughter can increase pressure on the bladder and trigger leakage.
Exercise
Running, jumping, aerobics, weightlifting, and other high-impact activities can trigger urine leakage.
Lift Something Heavy
Heavy lifting increases abdominal pressure and can place additional stress on the bladder and pelvic floor.
Bend Over
Some people notice leakage when bending down or changing position.
Have Sexual Activity
Stress incontinence can sometimes cause urine leakage during sexual activity. You do not necessarily have leakage every time one of these activities occurs. A fuller bladder can make leakage more likely.
Stress Incontinence vs Urge Incontinence
Stress incontinence and urge incontinence are different conditions.
| Feature | Stress Incontinence | Urge Incontinence |
|---|---|---|
| Main trigger | Coughing, sneezing, exercise, lifting | Sudden strong urge to urinate |
| Bladder pressure | Physical pressure causes leakage | Bladder muscle contractions cause leakage |
| Urgency | Usually absent | Usually present |
| Common example | Urine leaks while running | Urine leaks before reaching the bathroom |
| Common treatment | Pelvic floor training, devices, surgery | Bladder training, medications and other treatments |
Some people have both conditions. This is called mixed urinary incontinence.
Risk Factors for Stress Incontinence
Several factors can increase the risk of developing stress incontinence.
These include:
- Pregnancy
- Vaginal childbirth
- Multiple pregnancies
- Menopause
- Increasing age
- Overweight or obesity
- Chronic coughing
- Smoking
- Pelvic organ prolapse
- Pelvic floor weakness
- Prostate surgery
- Certain neurological conditions
- Previous pelvic surgery
Not everyone with these risk factors will develop stress incontinence.
How Is Stress Incontinence Diagnosed?
A healthcare professional usually starts with a detailed medical history and physical examination. The goal is to determine what type of urinary incontinence is present and whether another condition could be contributing to the symptoms.
Medical History
Your healthcare professional may ask:
- When the leakage started
- How often it occurs
- How much urine leaks
- What activities trigger leakage
- Whether you experience urgency
- Whether you have pelvic pain
- Whether you have had children
- Whether you have undergone pelvic or prostate surgery
- What medications you take
Bladder Diary
You may be asked to keep a bladder diary for several days.
This can record:
- How much you drink
- When you drink
- When you urinate
- How often leakage occurs
- What you were doing when leakage occurred
- Whether you felt an urge before leaking
A bladder diary can help identify patterns and distinguish different types of urinary incontinence.
Physical Examination
Depending on your symptoms, the examination may include a pelvic examination in women or another examination appropriate to your symptoms.
Urine Testing
A urine test may be used to check for infection, blood, or other abnormalities that could contribute to urinary symptoms.
Urinary Stress Test
During a stress test, the healthcare professional may ask you to cough or bear down while your bladder is full to see whether urine leakage occurs. This can help support a diagnosis of stress incontinence.
Additional Testing
Many people with straightforward stress incontinence do not need extensive testing. If the diagnosis is unclear, symptoms are complicated, or surgery is being considered, additional testing may include measurement of urine remaining in the bladder, urodynamic testing, cystoscopy, or imaging.
Stress Incontinence Treatment
Treatment depends on the severity of leakage, the underlying cause, your overall health, and your personal preferences.
Pelvic Floor Muscle Exercises
Pelvic floor muscle exercises, commonly called Kegel exercises, are one of the most important nonsurgical treatments for stress incontinence. These exercises strengthen the muscles that support the bladder and help control the urethra. A pelvic floor physical therapist can help you identify and correctly contract the appropriate muscles. Consistency is important. Pelvic floor exercises generally need to be performed regularly to provide benefit.
Biofeedback
Biofeedback may be used to help people learn how to correctly contract their pelvic floor muscles. A healthcare professional or physical therapist can explain whether this approach is appropriate.
Weight Management
If you are overweight or obese, losing excess weight may reduce pressure on the bladder and pelvic floor and improve stress incontinence symptoms.
Treat Chronic Cough
If chronic coughing is contributing to leakage, treating the underlying cause of the cough may reduce repeated pressure on the bladder.
Avoid Constipation
Constipation can place additional strain on the pelvic floor. Eating enough fiber and maintaining regular bowel movements may help reduce this strain.
Pessary and Other Devices
A vaginal pessary is a medical device that can be used by some women with stress incontinence. The device is inserted into the vagina and provides support around the urethra, which may reduce leakage during physical activity. Some disposable vaginal inserts are also designed to support the urethra and reduce leakage. These devices can be useful for people who want to avoid or delay surgery.
Is There a Medication for Stress Incontinence?
There is currently no medication approved in the United States specifically to treat stress incontinence, according to Mayo Clinic. This is different from urgency incontinence, for which several medications may be used. Treatment should therefore be based on the type of urinary incontinence rather than simply treating all urine leakage in the same way.
Surgery for Stress Incontinence
Surgery may be considered when conservative treatments do not provide enough improvement or when symptoms are significantly affecting quality of life.
Midurethral Sling
A midurethral sling is one of the most commonly used surgical procedures for female stress urinary incontinence. The sling supports the urethra and helps prevent urine leakage during activities that increase bladder pressure.
Urethral Bulking
Bulking agents can be injected into tissues around the urethra to increase support and help the urethra remain closed.
Bladder Neck Suspension
Procedures such as retropubic colposuspension can support the bladder neck and urethra.
Treatment in Men
Men with persistent stress incontinence after prostate treatment may be candidates for procedures such as a male sling or artificial urinary sphincter, depending on the severity and cause. The risks and benefits of surgery should be discussed with a urologist or urogynecologist.
Can Stress Incontinence Be Cured?
Stress incontinence can often be significantly improved and, in some people, eliminated with treatment. The best treatment depends on the cause and severity. Some people improve with pelvic floor muscle training and lifestyle changes. Others may need a pessary, urethral bulking, or surgery. The fact that urine leakage occurs does not mean you simply have to live with it.
When Should You See a Doctor?
Talk with a healthcare professional if urine leakage:
- Happens repeatedly
- Interferes with exercise
- Affects work or social activities
- Causes embarrassment or anxiety
- Limits sexual activity
- Requires frequent pads
- Is getting worse
- Occurs after childbirth
- Develops after prostate surgery
NIDDK recommends discussing bladder control problems with a healthcare professional rather than ignoring persistent leakage.
When Is Urinary Leakage More Urgent?
Urine leakage itself is usually not an emergency, but certain accompanying symptoms require prompt medical attention.
Seek medical care if you have urinary leakage along with:
- Blood in the urine
- Painful urination
- Inability to urinate
- Severe pelvic pain
- Recurrent urinary infections
- Sudden major changes in bladder function
NIDDK specifically advises medical evaluation for blood in the urine, painful urination, inability to empty the bladder, or significant urinary frequency.
