Some women do not leak when they cough or run. Instead, a strong urge arrives suddenly, and the bladder empties on the way to the toilet or while fumbling with the door. This pattern is called urgency incontinence, and it is part of what is often called overactive bladder. It is a different problem from stress leaking, and the two are managed differently.
Urgency has several possible contributors: bladder muscle that contracts too readily, bladder irritants such as caffeine and fizzy drinks, constipation, urine infections, and lower oestrogen after menopause. Sometimes a bladder that does not empty fully produces similar symptoms, and a tight pelvic floor can too. This is why a single assessment, rather than assuming one cause, is the sensible first step.
Useful first measures are often simple: a bladder diary for a few days, adjusting the timing and type of drinks, treating constipation, and bladder training that gradually lengthens the interval between toilet visits. Pelvic floor exercises are used when they suit the pattern, and medicines or other options are discussed if these are not enough. None of this promises a particular result, but most women find the pattern becomes easier to manage.
See a doctor if you cannot reach the toilet in time more than occasionally, if you pass urine very frequently by day or wake several times at night, if you have burning, blood in the urine or fever, or if you leak without noticing. Consultations are in English or Thai, with a fee of 1,500 to 3,000 baht by complexity plus a 300 baht clinic service fee.
