There are many types of urinary incontinence.
Urge incontinence is caused mainly by the presence of elements that irritate the bladder, such as the presence of urinary tract infection, bladder stones or even bladder tumours.
Overactive bladder syndrome (OAB) is a diagnosis of exclusion where there are no identifiable causes irritating the bladder, yet there is a severe urge to empty the bladder.
Stress urinary incontinence (SUI) is usually related to a weak pelvic outlet from previous trauma, multiple pregnancies, or undue repeated high abdominal pressure such as recurrent persistent cough, obesity or constipation.
Overflow incontinence occurs when the bladder is very full but unable to empty, and is related to weak bladder contraction in diabetics or patients affected by stroke.
Women who have had vaginal deliveries or are post-menopausal are at higher risk. You are also at risk if you are obese. Intake of irritants such as coffee or tea may worsen the problem.
