The bladder is a hollow organ located in the abdomen that temporarily holds urine produced by the kidneys. As the bladder fills with urine, nerve signals are sent to the brain, which causes the urge to urinate. These signals from the brain coordinate the relaxation of pelvic floor muscles and urethral sphincter muscles. Then, it directs the bladder muscles to contract and expel urine through the urethra.
An overactive bladder is a condition in which there is a loss of coordination of bladder muscles. The muscles responsible for urination have the remarkable ability to initiate contractions independently, even without direct signals from the brain. This intrinsic capability allows these muscles to expel urine through the urethra. This is a process that can occur even when the volume of urine in the bladder is relatively low. This results in an urgent, uncontrollable need to urinate, and may lead to urine leakage if a bathroom cannot be reached immediately. There are two types of overactive bladder: a dry form that occurs without an overwhelming urge to urinate (hence no urine leakage), and a wet form that is characterized by an uncontrollable need to urinate (therefore, leakage or involuntary voiding occurs).
Overactive bladder is a common problem, especially in older adults (though it is not a normal result of aging). It affects 1 in every 11 people in the United States, mostly those aged 60 and older. However, women may be affected earlier, often in their mid-forties.
The four main symptoms of an overactive bladder are:
Frequent urination:
Also called urinary frequency, this refers to an urge to urinate that is more frequent than usual. Urinary frequency can disrupt a normal daily routine or interfere with sleep. For example, while most people urinate 6-7 times per day after consuming about 2 liters of fluid, someone with urinary frequency may urinate 8 or more times within 24 hours.
Urgency:
Urinary urgency refers to a sudden, uncontrollable urge to urinate. It is caused by involuntary contractions of bladder muscles and feels like painful straining. Uncontrolled loss or leakage of urine may follow if a person is not able to urinate immediately. It tends to occur alongside, and is usually related to, urinary frequency.
Nocturia:
Waking up at least once each night to urinate is called nocturia. Normally, a person should be able to sleep for 6-8 hours without having to wake up to go to the bathroom. However, when a person has an overactive bladder, involuntary contractions of the bladder may occur at any time at night, leading to the need to wake up more than once every night to urinate. This can disrupt the normal sleep cycle and impact quality of life.
Unintentional loss of urine:
The strong, sudden, and uncontrollable urge to urinate that occurs in people with an overactive bladder is often followed by accidental loss or leakage of urine. This is because a person is not usually able to hold the urine long enough to reach the bathroom. Leakage of urine can be embarrassing and may force a person to avoid normal social or routine activities.
There are a number of effective treatments for an overactive bladder. These include behavioral strategies such as dietary changes, fluid schedules, prompted and timed voiding, bowel programs, and absorbent garments. However, if the symptoms of urinary incontinence become notably distressing or significantly disrupt one’s daily life, a doctor can opt to prescribe medications as part of the treatment plan. These medications may include antispasmodics or anticholinergics, such as tolterodine (Detrol), oxybutynin (Ditropan), oxybutynin skin patch (Oxytrol), trospium (Sanctura), or solifenacin (Vesicare). Their purpose is to reduce the number of urge episodes experienced by the individual.
An alternative treatment option is the sacral nerve stimulator. In this procedure, a pacemaker-type device is surgically placed under the skin of the abdomen. It is then connected to a wire that is positioned near the sacral nerves, which are located near the tailbone. This device can help regulate the bladder muscles and reduce the number of involuntary contractions.
It is important to see a doctor if you are experiencing symptoms of an overactive bladder, as it is a treatable condition. The doctor can help determine the underlying cause and recommend the appropriate treatment. In some cases, underlying medical conditions, such as urinary tract infection, may be contributing to the symptoms, and treating these conditions may improve bladder control.
Conclusion
In summary, an overactive bladder is a condition in which the bladder muscles contract involuntarily, leading to a strong, urgent need to urinate. This can cause frequent urination, urinary urgency, nocturia, and unintentional loss of urine. Urinary incontinence is more frequently observed among older adults. However, it’s important to note that it is not a natural consequence of aging. Fortunately, there are several effective methods available for managing and treating this condition. These methods encompass a range of approaches, including behavioral strategies and the use of medications. If you are experiencing symptoms of an overactive bladder, it is important to see a doctor for a proper diagnosis and treatment plan.
