Interstitial Cystitis (Bladder Pain Syndrome)
Interstitial cystitis (IC), also called bladder pain syndrome (BPS), is a chronic condition marked by pelvic/bladder pain, urinary urgency, and frequency without evidence of active infection. Many people cycle through flares and remissions. Comparing Western and Eastern approaches matters because conventional care can reduce symptoms but does not reliably resolve them for everyone, and some patients prefer or benefit from adjunctive nonpharmacologic options that target stress, pelvic-floor dysfunction, and whole-person factors.
From a Western perspective, IC/BPS likely arises from several overlapping processes: a compromised bladder lining (glycosaminoglycan layer) that permits irritants to penetrate the urothelium; neurogenic inflammation and central sensitization amplifying pain; mast cell activation and local immune dysregulation; pelvic-floor muscle hypertonicity; and, in a subset, visible inflammatory ulcers (Hunner lesions). Diagnosis is clinical after ruling out infection and other causes (e.g., stones, gynecologic or neurologic disorders) with history, exam, urinalysis/culture, and targeted tests. Symptom indices (ICSI/ICPI, PUF), bladder diaries, and selective use of cystoscopy (especially to identify/treat Hunner lesions) help guide care. Guidelines emphasize stepwise, multimodal treatment starting with education, behavioral strategies, stress reduction, pelvic-floor–focused physical therapy, and dietary modification; progressing to oral medications or intravesical therapies; and, for refractory disease, procedural options.
Conventional treatments with supportive evidence include pelvic-floor myofascial physical therapy (which addresses trigger points and hypertonicity); oral agents such as amitriptyline (neuromodulatory/anticholinergic effects), hydroxyzine (antihistamine for mast-cell–linked symptoms), cimetidine or other H2 blockers, pentosan polysulfate sodium (a bladder lining protectant), and pain modulators like gabapentin or pregabalin; and intru
