What kind of doctor treats Overactive Bladder?
A urologist, a doctor who treats the bladder and urinary tract, often treats overactive bladder. Women may also see a urogynecologist, a doctor who treats bladder and pelvic floor problems in women. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is overactive bladder?
Overactive bladder is a condition in which the bladder squeezes urine out at the wrong time. The key symptom is urgency, a sudden, strong need to pee that is hard to put off. Often the cause is unknown.
One review estimated that about 12 in 100 people have it. It is most common after age 40, but it can affect children and young adults too. It can get in the way of work, travel, exercise, sleep, and sex.
Symptoms
MedlinePlus says you may have overactive bladder if you have two or more of these symptoms:
- You urinate eight or more times a day or two or more times at night.
- You have a sudden, strong need to urinate right away.
- You leak urine after a sudden, strong urge to urinate.
Leaking urine is called incontinence, a loss of bladder control. Only about a third of people with overactive bladder leak urine after an urge. This is called wet overactive bladder. Waking up at night to urinate is called nocturia. It is the most bothersome symptom for many older adults.
Causes and who gets it
MedlinePlus lists nerve problems, too much fluid, and too much caffeine as causes. Diseases of the brain and nerves are strongly linked to bladder problems. Overactive bladder also becomes more common with aging.
Some medicines can add to bladder trouble. Water pills, called diuretics, make the body produce more urine.
How doctors diagnose it
There are usually no clear signs on an exam, so your doctor will ask careful questions about your symptoms and health. A urine test is done to look for infection and blood in the urine. Doctors also need to rule out serious problems that can look like overactive bladder, such as nerve disease or cancer.
A bladder diary is often the first tool. It records your day-to-day bladder habits and patterns. A test called a post-void residual measures the urine left in the bladder after you go. It uses ultrasound or a thin tube.
Treatment
Treatment usually starts with simple steps, such as education, bladder training, and advice on how much to drink. Quitting smoking, losing weight, and cutting back on caffeine, acidic foods, and alcohol can help. So can treating constipation and exercising. In bladder training, you urinate at regular times and wait out the urge in between. Pelvic floor exercises teach you to tighten the muscles that support the bladder when you feel an urge.
Medicines are used after these steps have been tried. Anticholinergic medicines, also called antimuscarinics, relax the bladder muscle. Their most common side effects are dry mouth and constipation. They can also dry the eyes. More serious effects, such as confusion, happen mostly in older people. It can take anywhere from a few days to 12 weeks to see the full effect.
Another medicine, mirabegron, works in a different way and seems to cause dry mouth less often. Your doctor will ask about high blood pressure first, because it may rule this medicine out.
If these steps do not help, see a bladder specialist. Options include Botox injections into the bladder muscle and nerve stimulation. Botox for the bladder wears off, so repeat shots are needed in about six months to a year. It carries a small risk of urinary retention, which means not being able to empty the bladder, and its main side effect is urinary tract infection.
Doctors say a cure is not a realistic goal, but many people can get better.
When to see a doctor
See a doctor if bladder urges or leaks disrupt your sleep, work, or daily life. Many people do not seek help. Also tell your doctor about blood in your urine or pain when you urinate. Doctors check for infection, blood in the urine, and other serious problems that can look like overactive bladder.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either kind of doctor can review your symptoms and medicines, order a urine test, start simple steps such as bladder training, and refer you to a urologist if needed.
Common questions
Does overactive bladder only affect older people?
No. It is most common after age 40, but it can affect children and young adults too.
Can overactive bladder be cured?
Not usually. A complete cure is rare, but treatment helps many people.
Do overactive bladder medicines have side effects?
Yes, they can. Dry mouth and constipation are the most common. Doctors weigh the benefits of a medicine against its side effects.
Is overactive bladder the same as stress incontinence?
No, they are different problems, but some people have both. Stress incontinence is leaking caused by effort or overexertion.
Can caffeine make overactive bladder worse?
It can. MedlinePlus lists too much caffeine as a cause of overactive bladder.
