If you have it, you know overactive bladder (OAB) is a “gotta go now” feeling. While that’s an easy way to explain the condition to a doctor or loved ones, it isn’t as simple to find out what causes it in the first place.
There are two types of overactive bladder:
- "Dry" means you have a sudden, urgent need to urinate many times during the day.
- "Wet" means you also have the need to pee and your bladder leaks. This is also called urge incontinence.
Both can happen without any underlying health condition.
However, other health problems, the things you drink, or the medications you take can also trigger your OAB symptoms. When you figure out the cause of your OAB, you can take better control of it.
How Does Nerve Damage Cause OAB?
Normally, nerve signals trigger your bladder to squeeze out urine when it gets full. But damaged nerves can tell your bladder to squeeze when it isn’t full. Nerve damage can also cause the muscles around the urethra (the tube that takes urine out of your bladder) to be too loose. That leads to leaks. Such damage can come from:
What Else Causes OAB Symptoms?
There are several other reasons you could have problems that feel like overactive bladder:
Weak pelvic muscles. A woman’s pelvic floor muscles are like a sling that holds up her uterus and bladder. The strain of pregnancy and childbirth can stretch them and make them weak. When that happens, your bladder can sag out of its normal place. The opening of the urethra stretches, too, and urine leaks out.
Diuretic medications. Sometimes called water pills, they’re often prescribed for high blood pressure. They help your body get rid of salt and water, so your bladder can fill up fast and may even leak.
Aging and menopause. Your bladder changes after menopause. Doctors aren’t sure if it’s due to a lack of estrogen, which makes up bladder tissue, aging, or a bit of each.
Extra weight. Added pounds are linked to OAB and urine leaks (your doctor will call this urinary incontinence). We know excess weight puts more pressure on your bladder. Doctors are looking into other reasons.
Quick Tips to Help You Manage OAB
For many people, lifestyle changes and exercises can improve symptoms.
- Avoid foods and drinks that make your bladder problems worse, such as citrus, caffeine, soda, and tomatoes.
- After you pee, wait a few seconds and try to go again.
- Set a schedule, and try to go whether you have to or not.
- Do Kegel exercises: Tighten and relax the muscles you use to stop urine midstream.
Your doctor can also prescribe medicines to calm your bladder. In more serious cases, he might try botulinum toxin (Botox) injections to calm the muscles in your bladder.
What Else Could It Be?
The main symptoms of OAB can also occur in other conditions:
