Interstitial Cystitis (Bladder Pain Syndrome)

Interstitial cystitis (IC) is a chronic, or long-lasting, condition that causes painful urinary symptoms. Between 4 and 12 million people in the United States may have IC.

People with IC have discomfort, pressure, tenderness, or pain in the bladder, lower abdomen, and pelvic area. Symptoms vary among people, may come and go, and can change over time.

Health care professionals diagnose IC by ruling out other conditions with similar symptoms. They will use your medical history, a physical exam, and lab and other tests to help diagnose IC.

You may be able to treat your IC with lifestyle changes. Your health care professional may also recommend bladder training, physical therapy, medicines, bladder stretching, bladder instillation, or a combination of these treatments.

Some research suggests diet may affect IC symptoms. Many people find that certain foods and drinks can make their IC symptoms worse, such as alcohol, citrus juices, chocolate, and tomatoes.

NIDDK conducts and supports clinical trials in many diseases and conditions, including urologic diseases. The trials look to find new ways to prevent, detect, or treat disease and improve quality of life.

The urinary tract is the body’s drainage system for removing urine, which is composed of wastes and extra fluid. In order for normal urination to occur, all body parts in the urinary tract need to work together in the correct order.
