ICD-10: N30.1 Medically Verified

Interstitial Cystitis (Painful Bladder Syndrome)

Medically reviewed by the SEDU Clinical Review Board. Detailed pathophysiology, symptoms, and care guidelines.

Clinical Overview

A chronic bladder condition causing pelvic pain, bladder pressure, and urinary urgency/frequency, characterized by glycosaminoglycan (GAG) layer degradation.

Associated Symptoms

  • Urinary Urgency & Frequency
  • Chronic Pelvic Pain
  • Dyspareunia (Painful Intercourse)

Treatment Pathways

  • Bladder Instillation (Rescue Solution)
  • Pelvic Floor Physical Therapy (PFPT)
  • Lifestyle & Anti-Inflammatory Diet
  • Acupuncture & Neuromodulation

Causes & Mechanisms

Defects in the protective bladder lining (GAG layer) allowing toxic urine solutes to penetrate the bladder wall, triggering mast cell activation and neural inflammation.

Risk Factors

Female sexHistory of chronic urinary tract infectionsCo-existing IBS or fibromyalgia

Diagnosis & Screening

Primarily clinical history and exclusion of active UTI; cystoscopy showing glomerulations or Hunner's ulcers is diagnostic in a subset of patients.

Prevention & Care Guidelines

Dietary trigger avoidance (caffeine, alcohol, citrus, spicy foods), oral pentosan polysulfate sodium, bladder instillations, and physical therapy.

Frequently Asked Questions

Q:Is interstitial cystitis an active infection?

No. IC urine cultures will show no bacterial growth, though symptoms mimic a UTI.
