Some symptoms of an overactive bladder can include: a sudden urge to urinate which is difficult to control and urinating frequently (usually more than 8 times in a single day).

To be honest, it is most likely for adults to have an overactive bladder than for kids.

An overactive bladder can be caused by various normal situations which do not require any treatment. Before considering that an overactive bladder is a problem, consider whether the intake of fluids has increased particularly alcohol. Weather conditions and age also affect the bladder control without being due to any medical problem. Overactive bladders often produce discolored urine from a simple darkening of the urine to showing signs of blood.

No, overactive bladder should not cause bleeding.

Overactive bladder is the leakage of large amounts of urine at unexpected times, including during sleep.
