Urinary incontinence is the loss of voluntary bladder control that can cause leakage of urine. It can be temporary or last for a long time. There are four types of long-term or permanent incontinence:
- Stress incontinence—Most common type. Leakage occurs when there is extra pressure on the bladder. Triggers may include laughing, sneezing, lifting heavy objects, or exercise.
- Urge incontinence—Known as overactive bladder, a loss of bladder control following a strong urge to urinate. The bladder is unable to hold urine long enough to make it to a restroom.
- Overflow incontinence—The bladder will not empty, so urine builds up and the bladder overflows.
- Functional incontinence—There is normal bladder control, but the toilet cannot be reached in time.
People may have just one or a combination of these types.
Incontinence has several different causes. The cause could also be unclear. Temporary incontinence can be caused by:
- Muscle weakness
- Restricted mobility
- Endocrinological disorders such as diabetes

Stress incontinence may be caused by:
- Weakening of muscles that suspend the bladder
- Weakening of muscles that control urine flow
Urge incontinence is the accidental loss of urine when the bladder spasms for no reason. It may be caused or worsened by:
- Urinary tract infection
- Diabetes type 1 and type 2
- Bladder irritation such as a stone or a tumor
- Drugs such as hypnotics or diuretics
- Nerve damage due to:
- Excessive fluid intake
Overflow incontinence is caused by overfill and overflow of the bladder. It may be caused or worsened by:
- A bladder that is blocked, such as by a scar in the urethra
- Fecal impaction
- Drugs such as antidepressants, hypnotics, antipsychotics, antihistamines, or calcium channel blockers
- Vitamin B12 deficiency
- Weak bladder muscles
Nerve damage due to:
- Spinal cord injuries
- Other factors
Functional incontinence may be caused by:
- Medical conditions that make it difficult to move like severe arthritis
- Drugs that cause confusion or sedation
Some incontinence may be caused by a fistula. A fistula is an abnormal opening between the bladder and another nearby structure. The fistula can make it difficult for the bladder to act as it should.
Urinary incontinence is more common in women age 65 years or older. Things that may increase your chances of urinary incontinence are:
- Childbirth—History of multiple pregnancies or vaginal deliveries
- Urinary tract infection
- Chronic lung disease
- Previous hysterectomy or urethral surgery
- Pelvic organ prolapse
- Dementia, including Alzheimer disease
- Multiple sclerosis
- Spinal cord injury or disease
- Use of certain substances such as caffeine or alcohol
- Use of certain medications, such as cholinergic agents or alpha-agonists
Any loss of bladder control can be considered incontinence.
When Should I Call My Doctor?
Call your doctor if you have a loss of urine control. Your doctor can help you determine the underlying cause.
The doctor will ask about symptoms and past health. They will ask how often you empty your bladder and patterns of urine leakage. A physical exam will be done to look for any physical causes. A urologist may be recommended.
The flow of urine can be tested with:
- Stress test
- Urodynamic tests
Images of the urinary tract may be taken with:
Treatments are based on the cause of the urinary incontinence. Temporary incontinence may be relieved by managing the conditions associated with the incontinence.
Weight loss may help lower episodes of stress or urge incontinence in those who are overweight or obese.
Behavior changes and improving pelvic floor muscle strength can help. Behavior changes include:
- Decreasing caffeine—caffeine has been linked to worsening of urinary incontinence
- Planning frequent bathroom trips throughout the day to prevent accidents
Methods to increase strength in the pelvic floor muscles include:
- Kegel exercises —focuses on muscles that hold the bladder in place and those that control urine flow
- Painless electrical stimulation—may strengthen the muscles more quickly; helpful for stress incontinence
- Pelvic floor exercises using cone-shaped weights that are placed in the vagina
- Biofeedback—a device signals how strong you are at contracting your muscles during exercise
Surgical procedures may be done if other treatments are not helping. Surgical options include:
- Placement of strips of material or sutures to relieve pressure on the urethra. There are several different types of surgery. A urethral suspension is a common option. It uses mesh to help support the urethra.
- Collagen injection into the wall of the urethra. This substance bulks up the wall of the urethra to help stop leaks.
First steps include behavior changes and improving strength of pelvic floor muscles. Behavior changes include:
- Drinking less fluid throughout the day
- Avoiding caffeine and alcohol
- Avoiding drinking at bedtime
- Keeping a log of your urination schedule and accidents.
Kegel exercises can help strengthen pelvic floor muscles and relieve some symptoms.
Medications may be recommended. Anticholinergics are the most common medication. They can relax the muscles of the bladder. Other medications may be used in combination to help manage symptoms, such as botulinum toxin injections.
Nerve stimulation may help if other treatment do not give relief. A device will send pulses to the nerves that control the bladder. The pulse can improve bladder control.
Treatment is to allow the bladder to completely empty. If a blockage is causing the problems, surgery may be needed to open the urine pathways.
A catheter may be needed It will allow urine to fully drain from the bladder. Catheters can be used at home.
Other Management Steps
Absorbent pads or diapers can be used to manage urinary leakage. Plugs and patches can also be used to help hold urine in place.
A supportive device called a pessary may also be used. Pessaries are devices that raise the uterus or the prolapsed bladder. It can decrease pressure on the bladder.
Incontinence is a symptom of many other conditions. There are several ways to prevent incontinence:
- If advised by your doctor, do exercises to strengthen your pelvic floor muscles, such as Kegel exercises. This is especially important if you are pregnant.
- Reduce your intake of substances that lead to incontinence such as caffeine, alcohol, and certain drugs.
- Lose weight, if needed.
- Eat a healthy diet to avoid constipation.
