Interactive Guide to Internal Plumbing
To get the full experience of this Interactive Guide, turn up your volume. You’ll learn how a normal bladder and an overactive bladder function. You’ll also learn about OAB symptoms, and how VESIcare is thought to treat them.
Use the buttons to see how a normal bladder and an overactive bladder work, and how VESIcare may help.
A Normal Bladder
For people without OAB, urine passes from the kidneys to the bladder, and the bladder expands until it reaches full size.
Once the bladder expands to its full size, it sends a signal to alert the brain that it’s time to go to the bathroom.
When you’re ready to go, the brain sends a message back to the bladder, telling the bladder muscle to start contracting.
This starts the flow of urine, and as the bladder muscle continues to contract, the bladder empties. But what happens if you have OAB?
An Overactive Bladder
For people with OAB, bladder function is different. Instead of filling and emptying as it should, the bladder muscle contracts prematurely, before the bladder expands to its full size.
When the bladder contracts prematurely, it may result in OAB symptoms.
OAB symptoms can be unpredictable and uncontrollable. What are they? Continue on to learn more.
Symptoms of an Overactive Bladder
Common symptoms of overactive bladder include: urgency, frequency, and leakage.
When the bladder muscle contracts before the bladder expands to its full size, you may experience urgency, the strong and sudden need to use the bathroom.
Another common OAB symptom is frequency, the need to use the bathroom 8 or more times a day.
OAB may also result in accidental leaks from time to time. But VESIcare may be able to help.
How VESIcare Is Thought to Work
A natural body chemical called acetylcholine binds to receptors on the bladder, causing the bladder muscle to contract.
VESIcare works by blocking acetylcholine from binding to these receptors.
As a result, VESIcare may help control and reduce OAB symptoms.
