A chronic condition causing bladder pressure, pelvic pain, and frequent, urgent urination without infection.

Overview

Interstitial Cystitis / Bladder Pain Syndrome (IC/BPS) is a chronic condition that causes discomfort or pain in the bladder and pelvic region, along with a frequent and urgent need to urinate. Unlike a urinary tract infection, IC/BPS is not caused by bacteria and does not respond to antibiotics. IC/BPS can affect people of all ages and genders but is more commonly diagnosed in women. The condition can significantly impact quality of life, affecting sleep, work, and relationships. Symptoms can fluctuate over time and may be triggered by certain foods, stress, or hormonal changes. While there is no cure, many treatments can help manage symptoms.

Common Symptoms

Symptoms include: • Chronic pelvic pain or pressure • Pain that worsens as the bladder fills • Frequent urination (often small amounts) • Urgent need to urinate • Pain during intercourse • Symptoms that worsen with certain foods (caffeine, alcohol, spicy foods, citrus) Symptoms can range from mild to severe and often go undiagnosed for years.

Diagnosis

Diagnosis involves: • Medical history and symptom assessment • Urine tests to rule out infection • Cystoscopy (examination of the bladder with a scope) • Potassium sensitivity test (in some cases) • Ruling out other causes of pelvic pain Diagnosis can take time, as symptoms overlap with other conditions.

Current Treatments

Treatment is individualized and may include: • Dietary modifications (avoiding trigger foods) • Oral medications ( Elmiron, antihistamines, nerve pain medications) • Bladder instillations (medication delivered directly into the bladder) • Physical therapy for pelvic floor dysfunction • Nerve stimulation (PTNS, sacral neuromodulation) • Stress management and psychological support A multi-disciplinary approach often works best.

Research Summary

Research into IC/BPS is ongoing, with studies exploring the role of the bladder lining (glycosaminoglycan layer), neurogenic inflammation, and the connection between IC/BPS and other chronic pain conditions. More research is needed to understand the underlying causes and develop better treatments.

Community Resources
