Overactive Bladder Symptoms & Treatment | Dr. Theodore Cisu

The short answer: Overactive bladder (OAB) causes sudden, hard-to-delay urges to urinate, often with frequent trips to the bathroom, waking at night, and sometimes leaking. It's common in both women and men and very treatable. Options include bladder training and other habit changes, pelvic floor therapy, medication and office-based procedures, chosen to fit your goals.

Written by Theodore Cisu, MD, board-certified urologist. Based on the American Urological Association (AUA) and Society of Urodynamics, Female Pelvic Medicine and Urogenital Reconstruction (SUFU) guideline on the diagnosis and treatment of idiopathic overactive bladder (2024).

What is overactive bladder?

Overactive bladder is a group of symptoms built around urgency: a sudden, strong need to urinate that's hard to put off. Normally, your bladder fills quietly and you decide when to empty it. With OAB, the bladder sends "go now" signals early or at the wrong time.

OAB isn't an infection, and it isn't simply a normal part of aging that you have to live with. "Idiopathic" OAB means there's no single clear cause, such as a nerve condition, behind it.

Symptoms of overactive bladder

• Urgency: a sudden, strong need to go
• Frequency: urinating more often than feels normal for you during the day
• Nocturia: waking up at night to urinate
• Urge incontinence: leaking on the way to the bathroom, or when you can't get there in time

Not everyone with OAB leaks. Many people have urgency and frequency without any leakage, and that still counts as OAB and is worth treating if it bothers you.

What causes overactive bladder?

Often there's no single cause. Several things can make symptoms worse, and treating them can help:

• Caffeine, alcohol and carbonated drinks
• Drinking large amounts of fluid, especially in the evening
• Constipation
• Extra body weight
• Diabetes
• In women, pelvic organ prolapse and the vaginal tissue changes that come with menopause
• In men, an enlarged prostate (BPH), which can cause similar symptoms

How is overactive bladder diagnosed?

For most people, the diagnosis is straightforward. The AUA/SUFU guideline recommends starting with:

• A careful history of your symptoms, fluid habits, medications and other conditions
• A physical exam
• A urine test to check for infection and blood

Your urologist may also ask you to fill out a short symptom questionnaire or keep a bladder diary for a few days, recording what you drink, when you urinate and any leaks. If you have trouble emptying, a quick bladder scan checks how much urine is left after you go.

Most people don't need cystoscopy, imaging or detailed bladder pressure testing (urodynamics) at the start. These are saved for cases where the diagnosis isn't clear, or when there's blood in the urine or other warning signs. The guideline also notes that telehealth works well for both first visits and follow-ups.

Treatment options

The 2024 guideline moved away from a strict "first-line, second-line, third-line" ladder. Treatments are grouped by how invasive they are, and you and your urologist choose what fits your symptoms, goals and preferences. Treatments can also be combined. Choosing not to treat is also reasonable if your symptoms don't bother you much.

Bladder training and habit changes

The guideline strongly recommends offering bladder training to everyone with OAB. It works by slowly retraining your bladder to hold more and wait longer between trips. Helpful habits include:

• Urinating on a schedule, then gradually stretching the time between trips
• Using "urge suppression": when an urge hits, stop, stay still, squeeze your pelvic floor muscles a few times and take slow breaths until it passes
• Adjusting how much and when you drink, without getting dehydrated
• Cutting back on caffeine, alcohol and fizzy drinks
• Treating constipation and, if it applies, losing some weight

Pelvic floor therapy

Pelvic floor muscle training, often with a specialized physical therapist and sometimes with biofeedback, can calm urgency and reduce leaks. It helps both women and men.

Medications

Two main types of medicine can reduce urgency, frequency and urge leakage:

• Beta-3 agonists, such as mirabegron and vibegron, relax the bladder muscle as it fills.
• Antimuscarinics, such as oxybutynin, tolterodine, solifenacin and trospium, calm bladder muscle contractions. Common side effects include dry mouth and constipation. The guideline asks doctors to discuss a possible link between these medicines and dementia risk, which is a particular concern for older adults.

If one medicine doesn't work well or causes side effects, switching to another or combining the two types is an option.

Office-based procedures

If habit changes and medication haven't given you enough relief, or you'd rather not take a daily pill, the guideline recommends offering one of these:

• Bladder Botox injections (onabotulinumtoxinA). Medicine is injected into the bladder wall through a thin scope. Effects last for months, and repeat treatments are needed. Some people have trouble emptying afterward and need to use a catheter for a time, so your bladder emptying is checked before and after.
• Tibial nerve stimulation (PTNS). Gentle electrical pulses are sent through a nerve near the ankle that connects to the bladder's nerve pathways. It's usually given in a series of short office sessions.
• Sacral neuromodulation. A small implanted device sends signals to the nerves that control the bladder, usually after a trial period to see if it helps.

Dr. Cisu offers bladder Botox injections and nerve stimulation, including tibial nerve stimulation (PTNS) and sacral neuromodulation. He can help you decide which of these fits you. For the rare person with severe symptoms after all of these, larger reconstructive surgery is an option in specialized centers.

Overactive bladder in men

In men, OAB symptoms and prostate symptoms often overlap. An enlarged prostate can cause urgency and frequency, and the bladder can become overactive on its own. Your urologist will look at both. Treatment may combine a prostate medicine, such as an alpha-blocker, with a bladder medicine. See our article on the enlarged prostate (BPH).

Overactive bladder in women

After menopause, thinning of the vaginal and urinary tissues can add to urgency and leakage. Low-dose vaginal estrogen may help some women with these symptoms. Pelvic organ prolapse can also play a role and is worth checking for.

When to see a urologist

• Urgency, frequency or leakage affects your work, sleep, travel or social life
• Habit changes or medication haven't helped enough
• Medication side effects bother you
• You're worried about taking an antimuscarinic long-term

See a doctor promptly if you have blood in your urine, pain or burning with urination, fever, or trouble emptying your bladder. These aren't typical OAB symptoms and need their own evaluation. If you can't urinate at all, go to the emergency room.

Seeing Dr. Cisu for overactive bladder

Because OAB can usually be evaluated by telehealth, you can start from home anywhere in Virginia. Our office can request your records, urine tests and any imaging ahead of time so Dr. Cisu reviews them first. Second opinions are welcome, and no referral is needed. Book a visit.

Frequently asked questions

Is overactive bladder a normal part of aging?

It becomes more common with age, but it isn't something you just have to accept. Treatment helps many people at any age.

Can overactive bladder be cured?

OAB is usually managed more than cured. Many people get major relief with bladder training, pelvic floor therapy, medication or a procedure, and symptoms can improve a great deal.

Should I drink less water if I have OAB?

Not too much less. Cutting fluids too far can make urine more concentrated and irritating. A bladder diary helps you and your urologist find the right amount and timing for you.

What foods and drinks make overactive bladder worse?

Caffeine, alcohol and carbonated drinks are common triggers. Some people notice symptoms with acidic or spicy foods or artificial sweeteners. A diary can help you spot your own triggers.

Do OAB medications cause dementia?

Some research has linked antimuscarinic bladder medicines to a higher risk of dementia, especially with long-term use in older adults. The AUA/SUFU guideline asks doctors to discuss this risk. Beta-3 agonists are an alternative to consider.

Can men have overactive bladder?

Yes. OAB affects men and women. In men, the prostate often plays a part, so both are evaluated together.

How long does bladder Botox last?

The effect usually wears off after several months, and the treatment can be repeated. Your urologist can tell you what to expect for your situation.
