Leaking When You Cough or Exercise: Stress Incontinence

Do you leak urine when you cough, sneeze, laugh, lift something heavy, or exercise? This is called stress urinary incontinence, and it affects millions of people – particularly women who have had children. While common, it is not something you have to live with.

What Is Stress Incontinence?

Stress incontinence occurs when physical activity or movement puts pressure (stress) on your bladder, causing urine to leak. The problem is not with your bladder itself but with the muscles and tissues that support it – the pelvic floor. This is different from overactive bladder, where the urge to go comes first and leakage follows.

What Causes It?

Pregnancy and Childbirth: The weight of pregnancy and the process of vaginal delivery can stretch and weaken pelvic floor muscles.

Menopause: Reduced oestrogen levels can weaken the tissues supporting the bladder and urethra.

Surgery: Hysterectomy or prostate surgery can affect the muscles that control urination.

Chronic Coughing: Conditions like chronic bronchitis put repeated stress on the pelvic floor.

Obesity: Excess weight increases pressure on the bladder and pelvic floor.

High-Impact Exercise: Activities like running or jumping can worsen symptoms.

Treatment Options

Pelvic Floor Exercises: Supervised by a continence adviser or physiotherapist, these are effective in 50 to 70% of women (BAUS), and in some resolve the leakage. The full benefit takes three to six months, and they are continued for life.

Lifestyle Changes: Losing weight, treating chronic coughs, and avoiding constipation can reduce symptoms.

Vaginal Pessaries: These devices support the bladder neck and can be particularly helpful during exercise.

Bulking Agents: Injections around the urethra improve closure; BAUS puts success at 50 to 70%, with recurrence in about 20%.

Surgery: For more severe cases, colposuspension leaves 80 to 90% of women dry or significantly improved (BAUS), and can be performed laparoscopically or robotically.

Possible Side Effects

Pelvic floor training has no side effects beyond the time it takes. A pessary can cause discharge or irritation, may take more than one fitting, and should be removed and checked at least every six months (NICE NG123). Bulking injections are a minor procedure: almost everyone has mild burning and a little blood in the urine for a short time, around one in ten get a bladder infection or notice a slower flow, and because the effect can wear off, between one in two and one in five need a further procedure later (BAUS leaflet). NICE describes bulking agents as less effective than the operations and notes that repeat injections may be needed. Colposuspension is an operation under general anaesthetic: around one in ten women have difficulty emptying for a time and one in twenty need a catheter for longer, between one in ten and one in twenty develop new urgency, and two to three in ten find leakage returns or develop a vaginal prolapse in later years (BAUS leaflet). Which trade-off is acceptable depends on how much the leakage affects you and what you have already tried.

The usual next step

Leaking urine when you cough, sneeze, or exercise is common and treatable. The typical starting point is a GP visit. They can rule out simple causes such as a urinary infection, and most women are then referred to a continence physiotherapist for structured pelvic floor rehabilitation, which resolves or substantially improves symptoms in 50 to 70% of women when supervised (BAUS). Where conservative treatment does not help, a urology or urogynaecology consultation, via the NHS or privately, can set out the surgical options described above.
