Interstitial Cystitis: Diagnosis, Management and Impact on Daily Life

Interstitial cystitis (IC), also called painful bladder syndrome, is a long-lasting condition that causes pain, pressure, or burning in the bladder, often along with a frequent or urgent need to urinate. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) estimates that between 4 and 12 million people in the United States may have IC. It is diagnosed by ruling out other conditions that cause similar symptoms, since there is no single test that confirms IC on its own. The exact cause is unknown, and there is currently no cure, but several treatment approaches can help manage symptoms.

When to Seek Care Right Away

Bladder and pelvic pain can have several causes, some of which need prompt attention. Contact a provider or seek urgent care if you notice blood in your urine, fever or chills, sudden severe pain, or an inability to urinate. These can point to an infection, stones, or another condition that needs timely evaluation rather than a routine appointment.

Common Symptoms of IC

Symptoms of IC vary from person to person, can come and go, and may change over time. Common symptoms include:

Bladder pressure or discomfort, ranging from mild to severe
A frequent or urgent need to urinate
Burning pain in the pelvic area
Pain during intercourse

Many people with long-term IC also have other conditions, such as endometriosis, fibromyalgia, irritable bowel syndrome, other chronic pain syndromes, anxiety, or depression.

How Interstitial Cystitis Is Diagnosed

Health care professionals diagnose IC largely by ruling out other conditions that cause similar urinary symptoms. Your provider will typically use your medical history, a physical exam, and lab and other tests as part of that process. This can include:

Urine tests to check for infection or cells that suggest cancer
Cystoscopy, where the provider uses a thin tube with a small camera to look inside the bladder, and may take a small tissue sample (biopsy) of the bladder lining
In-office tests that show how well your bladder fills and empties

Conditions Your Provider Will Typically Rule Out

Sexually transmitted infections
Bladder cancer
Bladder infections
Kidney or ureteral stones

IC is sometimes confused with repeated urinary tract infections, so if you suspect IC, it’s worth mentioning that specifically to your provider, since it is not always easily recognized.

Treatment Approaches

There is no cure for IC and no single standard treatment. Care is generally based on trial and error, and results vary from person to person. A provider may combine several approaches.

Diet and Lifestyle Changes

Some people find that adjusting their diet helps control symptoms. One approach is removing foods and drinks linked to bladder irritation one at a time to see whether symptoms improve, rather than cutting many things out at once. Items commonly discussed include caffeine, chocolate, carbonated beverages, citrus drinks, and spicy or highly acidic foods. Your provider or a dietitian can help you work through this process safely.

Bladder Training and Pelvic Floor Therapy

Some providers recommend bladder training, such as urinating on a set schedule, or pelvic floor physical therapy and biofeedback to help ease pelvic floor muscle tension.

Medications

A provider may consider medicines as part of a combination approach, which can include an oral medicine specifically approved for IC, certain antidepressants used at lower doses for pain and urinary frequency, or an antihistamine that may help reduce inflammation but can cause drowsiness. Whether any of these fit your situation, and at what dose, is a decision for your prescribing provider based on your health history.

Other Procedures

For some patients, additional options may include stretching the bladder with fluid under general anesthesia, medicine placed directly into the bladder, nerve stimulation (neuromodulation), or, in rare and difficult cases, surgery to remove the bladder. These are generally considered after other approaches, and a specialist can explain whether any apply to you.

Putting Interstitial Cystitis information into practice

Track your symptoms — when they happen, how severe they are, and anything that seems to trigger or ease them.
Bring this record to a primary care provider or gynecologist and mention that you suspect IC, since it can be confused with a urinary tract infection.
Ask about testing to rule out infection, stones, cancer, and other causes before assuming a diagnosis.
If IC is suspected or confirmed, ask for a referral to a urologist or urogynecologist experienced in treating it.
Discuss a step-by-step treatment plan, since most people try approaches in combination and adjust over time based on what helps.

Questions studies have not settled about Interstitial Cystitis

Women are about 10 times more likely than men to be diagnosed with IC, though men and, less commonly, younger people can also develop it. If you also have endometriosis, fibromyalgia, irritable bowel syndrome, or another chronic pain condition, let your provider know, since these often occur alongside IC and can affect how symptoms are managed. This article covers general information from national health resources. It does not cover every possible cause of pelvic or bladder pain, personalized testing plans, medication dosing, or individual treatment outcomes, which depend on your specific health history and should be discussed with your own provider.

Finding a Specialist Experienced with IC

A primary care provider or gynecologist can start the evaluation process, but ongoing management often works best with a urologist or urogynecologist who regularly treats IC. When looking for a specialist, it can help to ask your referring provider specifically for someone experienced with interstitial cystitis or bladder pain syndrome, rather than general urology, since treatment approaches and familiarity with newer options can vary between providers.

Common questions about Interstitial Cystitis

Is interstitial cystitis the same as a urinary tract infection?

No. IC causes symptoms similar to a urinary tract infection, but it is a different condition and is often confused with repeated infections. This is one reason it can take time to reach a correct diagnosis.

Can interstitial cystitis be cured?

There is currently no cure. Treatment focuses on managing symptoms, and results vary from person to person. Some people respond well to simple changes, while others need more extensive treatment.

Does diet cause interstitial cystitis?

The exact cause of IC is unknown, and diet is not considered a cause. Some people do notice that certain foods and drinks affect their symptoms, and removing items one at a time can help you identify your own patterns, ideally with input from your provider.

Who is most likely to develop interstitial cystitis?

IC is diagnosed far more often in women than men — about 10 times more often — and most often appears between ages 20 and 40, though it has been reported in younger people as well.
