A stroke may sometimes cause a decrease in sensation and control of the bladder. This may lead to the person experiencing frequency and/or urgency with urination, or possibly incontinence. In some cases, especially if the stroke has occurred in the brainstem, there may be total loss of bladder control. Bowel control and constipation may also be problems following a stroke. Bowel and bladder problems after stroke are often temporary and can be helped by your rehabilitation team.
