Interstitial cystitis (IC) is a chronic condition characterized by bladder pressure, pain, and frequent urination. It can cause discomfort in the pelvic area and may lead to a reduced quality of life. The exact cause of IC is not well understood, but it is believed to involve inflammation of the bladder lining. Symptoms of IC can vary widely among individuals and may include urgency to urinate, pain during intercourse, and bladder fullness. Diagnosis typically involves ruling out other conditions, and treatment options may include medications, physical therapy, and lifestyle changes to help manage symptoms.
