Interstitial Cystitis: Understanding Chronic Bladder Pain

Interstitial cystitis (IC), also referred to as bladder pain syndrome, is a chronic condition that causes bladder pressure, bladder pain, and sometimes pelvic pain. Unlike a urinary tract infection (UTI), interstitial cystitis may be caused by a variety of factors, which can make the condition difficult to diagnose and manage.

This condition can affect anyone, though it is more common in women and can significantly impact one's daily life, sleep and emotional well being.

What Is Interstitial Cystitis?

Interstitial cystitis is a chronic bladder condition characterized by inflammation and irritation of the bladder wall. This irritation can cause discomfort ranging from mild pressure to severe pelvic pain.

Normally, the bladder expands as it fills with urine and signals the brain when it is time to urinate. In people with IC, these signals become disrupted, leading to frequent urges to urinate even when the bladder is not full.

According to the Centers for Disease Control and Prevention (CDC), about 1% of people in the United States may have interstitial cystitis. The condition can last for years and even become lifelong for some individuals.

Common Symptoms

Symptoms of interstitial cystitis vary from person to person and may come and go in flare up episodes. Common symptoms patients may experience include chronic pain or pressure in the bladder or pelvic area (below the belly button), an urgent and frequent need to urinate, often in small amounts, a burning or painful sensation during urination, pain or discomfort as the bladder fills, relief after urinating, and pain during sexual intercourse. Some people may need to urinate dozens of times a day, and symptoms can worsen during stress, menstruation, exercise, or prolonged sitting.

What Causes Interstitial Cystitis?

The exact cause of interstitial cystitis remains unknown; however, researchers believe multiple factors may contribute to the condition. Many think that a trigger, caused by one or more events, may initially damage the bladder or its lining, and ultimately lead to the development of IC. Some theorized triggers include bladder trauma (such as from pelvic surgery), prolonged time between access to a bathroom (bladder overdistension), pelvic floor muscle dysfunction, cystitis (bacterial infection of the bladder), autoimmune disorder, pelvic inflammation or hypersensitivity, and spinal cord trauma. Due to no definitive cause, IC is considered a multifactorial condition that involves several biological and environmental factors. Current thinking is that this damage to the bladder wall is allowing particles within the urine to leak into the lining of the bladder. Once in the bladder lining, these particles can lead to a variety of bodily responses that may further damage the bladder.

In patients who develop IC, researchers speculate that continued damage to the bladder may be due to the normal repair of the bladder not occurring. Studies have shown that a protein called antiproliferative factor (APF) is produced by the cells of patients with IC but not those of healthy people. This protein prevents the growth of bladder cells and thus the bladder may be unable to repair itself when present.

Who Is at Risk?

While anyone can develop interstitial cystitis, certain groups appear to have a higher risk.

Risk factors include female gender, aged 30 or older at the time of diagnosis, and having other chronic pain disorders such as IBS or fibromyalgia as researchers have observed that IC may occur alongside other chronic inflammation or nerve sensitivity conditions.

How Is Interstitial Cystitis Diagnosed?

Diagnosing interstitial cystitis can be challenging because its symptoms often resemble other urinary conditions, especially UTIs; however, IC may be caused by a variety of factors listed above. IC is usually diagnosed by a healthcare provider after reviewing symptoms and medical history, performing urine tests to rule in or out possible bacterial or fungal infections, conducting bladder and/or pelvic exams, and sometimes by performing imaging. It is often a diagnosis of exclusion, meaning that it is not diagnosed until other possible causes of bladder pain have been ruled out.

Treatment and Management

There is currently no cure for interstitial cystitis, but many treatments can help manage symptoms and improve quality of life.

Treatment plans are often personalized and may include lifestyle changes such as stress management, avoiding trigger foods (caffeine, citrus, spicy foods), and regular physical activity, bladder training by gradually increasing the time between bathroom visits and techniques to improve bladder control, and oral medications for anti-inflammatory or pain relief, physical therapy for the muscles of the pelvic floor, and bladder instillation (medication placed directly into the bladder via catheter). Many patients find relief through a use of a combination of treatments and therapies rather than a single solution.

Living with Interstitial Cystitis

Living with interstitial cystitis can be challenging due to chronic pain and frequent urination. These symptoms may affect sleep, work, relationships, and mental health. However, with proper diagnosis and a personalized treatment plan, many individuals learn to manage symptoms effectively and reduce flare-ups. Working closely with a healthcare provider can help patients identify triggers and find therapies that improve daily life. Your healthcare providers are here to help you!
