ANNOUNCER: The trouble with caffeine is that it stimulates bladder muscles.
RAY RACKLEY, MD: Caffeine is a muscle stimulant and, if you have a hypersensitive or hyperactive bladder condition, you can imagine that caffeine actually makes that worse.

DIANE NEWMAN: Alcohol, beer, wine, cocktails, can affect the bladder. We find that, if someone has maybe a glass of beer before they go to bed or a glass of wine, that it may cause them to get up the night to urinate. Alcohol is a natural diuretic. It increases urine output. It also is a bladder irritant.
ANNOUNCER: Diuretics used to treat heart conditions can also aggravate bladder problems. So too can other heart medications, such as calcium channel blockers. And then there is smoking. Nicotine is a bladder stimulant. Smoking causes poor circulation, which is bad for the bladder. Coughing is a problem, too.
DIANE NEWMAN: A person who smokes for a long period of time who has chronic coughing, it actually puts pressure on the ligaments in the pelvis and can actually lead to some nerve damage in the pelvis, leading to urgency, frequency and incontinence.
