The cause of interstitial cystitis is unknown. While it can, it does not typically run in a family. The diagnosis is usually based on the symptoms after ruling out other conditions. Typically the urine culture is negative. Ulceration or inflammation may be seen on cystoscopy. Other conditions which can produce similar symptoms include overactive bladder, urinary tract infection (UTI), sexually transmitted infections, prostatitis, endometriosis in females, and bladder cancer.
There is no cure for interstitial cystitis and management of this condition can be challenging. Treatments that may improve symptoms include lifestyle changes, medications, or procedures. Lifestyle changes may include stopping smoking and reducing stress. Medications may include ibuprofen, pentosan polysulfate, or amitriptyline. Procedures may include bladder distention, nerve stimulation, or surgery. Pelvic floor exercises and long term antibiotics are not recommended.
In the United States and Europe, it is estimated that around 0.5% of people are affected. Women are affected about five times as often as men. Onset is typically in middle age. The term "interstitial cystitis" first came into use in 1887.
