Interstitial cystitis (IC) is a complex condition that is identified by chronic inflammation of the bladder muscle layers, which produces the following symptoms:
Discomfort can range from a mild burning sensation to severe pain. The degree of discomfort can be persistent or infrequent, and some people have periods of remission.
According to the Interstitial Cystitis Association, IC affects more than 12 million people in the United States. Women are much most likely to develop IC, but children and adult men can get it as well.
IC is also known as painful bladder syndrome (PBS), bladder pain syndrome (BPS), and chronic pelvic pain (CPP).
You may experience one or more of the following symptoms:
Your symptoms may vary from day to day, and you may experience periods when you are symptom-free. Symptoms may worsen if you develop a urinary tract infection.
The exact cause of IC is not known, but researchers postulate that several factors may damage the lining of the bladder and therefore trigger the disorder. These include:
Many people with IC also have irritable bowel syndrome or fibromyalgia. Some researchers believe that IC may be part of a generalized inflammatory disorder that affects multiple organ systems. Researchers are also investigating the possibility that people may inherit a genetic predisposition to IC. Although it is not common, IC has been reported to afflict blood relatives. Cases have been seen in mother and daughter, as well as in two or more sisters.
Research is ongoing to determine the cause of IC and to develop more effective treatments.
There are no tests that can be used to make a definitive diagnosis of IC. Therefore, many cases of IC go undiagnosed. Because IC shares many of the same symptoms of other bladder disorders, your doctor will need to rule these out first. These other disorders include:
You will be diagnosed with IC once your doctor determines that your symptoms are not due to one of these disorders.
IC can cause several complications, including:
There is no cure or definitive treatment for IC. Most people use a combination of treatments, and you may have to try several approaches before you settle on the therapy that provides the most relief. IC treatments may include:
Your doctor may prescribe one or more of the following drugs to help improve your symptoms:
Bladder distention is a procedure that stretches the bladder using water or gas. It can help relieve symptoms in some people, possibly by increasing the capacity of the bladder and by interrupting pain signals transmitted by nerves in the bladder. It can take two to four weeks to notice improvement in your symptoms.
Bladder instillation involves filling the bladder with a solution containing dimethyl sulfoxide (Rimso-50), also called DMSO. The DMSO solution is held in the bladder for 10 to 15 minutes before it is emptied. One treatment cycle typically includes up to two treatments per week for six to eight weeks, and the cycle can be repeated as needed.
It is thought that the DMSO solution may reduce inflammation of the bladder wall. It may also prevent muscle spasms that cause pain, frequency, and urgency.
Transcutaneous electrical nerve stimulation (TENS) delivers mild electrical pulses through the skin to stimulate the nerves to the bladder. TENS may help relieve symptoms by increasing blood flow to the bladder, strengthening pelvic muscles that help control the bladder, or triggering the release of substances that block pain.
Many people with IC discover that specific foods and beverages make their symptoms worse. Common foods that may worsen IC include:
Your doctor will help you to determine if you are sensitive to any foods or beverages.
Although there is no proven correlation between smoking and IC, smoking is definitely linked to bladder cancer. It is possible that quitting smoking may lessen or relieve your symptoms.
Maintaining an exercise routine may help you manage your symptoms. You may have to modify your routine, so that you avoid high impact activity that causes flares. Try some of these workouts:
A physical therapist can teach you exercises that will strengthen your bladder and pelvic muscles. Talk to your doctor about meeting with a physical therapist.
Techniques designed to lengthen the time between urinating may help relieve symptoms. Your doctor can discuss these techniques with you.
Learning to deal with life’s stresses and the stress of having IC may provide symptom relief. Meditation and biofeedback may be helpful.
There are several surgical options to increase the size of the bladder and remove or treat ulcers in the bladder. Surgery is rarely used and is considered only when symptoms are severe and other treatments have failed to provide relief. Your doctor will discuss these options with you if you are a candidate for surgery.
There is no cure for IC. It can last for years or even a lifetime. The main goal of treatment is to find the combination of therapies that best provides long-term symptom relief.
