A person who has been diagnosed with the medical condition known as overactive bladder, or OAB, has sudden urges to empty their bladder. In fact, most people with OAB visit the bathroom eight or more times a day. This medical condition is very common, affecting approximately 1 in 5 Canadians over the age of 35 years. When OAB is accompanied by an involuntary loss of moderate-to-large amounts of urine, the condition is called urge incontinence.
OAB is caused by sudden involuntary contractions of the detrusor muscle, which is in the wall of the bladder. Although OAB can occur at any age, it is more likely to occur as a person ages. However, it shouldn't be passed off as a normal part of growing older.
