Urinary Incontinence: Symptoms
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 can't 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 is an accidental loss of urine during physical activity or coughing, sneezing, and laughing. It 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 leaking of urine due to overfilling up and overflowing from 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.
