Interstitial Cystitis – Symptoms and Causes

ByJanis Updated

Understanding Bladder Inflammation

Interstitial cystitis is a long-term health problem. It causes pressure and pain in the bladder, and sometimes the pelvis. This condition is part of a group of problems called painful bladder syndrome.

The bladder is a hollow muscle that holds urine. When full, it sends signals to the brain through pelvic nerves, creating the urge to urinate.

People with interstitial cystitis have inflamed, irritated bladder walls compared to normal bladders.

This inflammation confuses the signals between the bladder and brain. As a result, they feel the need to urinate more often and in smaller amounts than most people.

Women are affected more often than men. This condition can greatly reduce quality of life. While there’s no cure, treatments can help manage symptoms.

Symptoms

Interstitial cystitis produces symptoms that differ from person to person. These symptoms can change over time and may worsen during certain activities or situations.

Common symptoms include:

  • Pelvic pain (women may feel pain between the vagina and anus, while men often experience pain in the perineum (area between the scrotum and anus)
  • Persistent urge to urinate that doesn’t go away
  • Frequent urination throughout the day and night, sometimes up to 60 times daily
  • Small urine amounts when going to the bathroom
  • Pain relief after emptying the bladder
  • Discomfort experienced during bladder filling
  • Pain during sexual activity

Many people experience symptom flare-ups triggered by:

  • Menstruation
  • Sitting for extended periods
  • Stress
  • Exercise
  • Sexual activity

Symptom severity varies widely among individuals. Certain individuals experience menstrual cycles without any accompanying symptoms.

Though these signs may seem like a urinary tract infection, most interstitial cystitis cases don’t involve infection. However, if someone with this condition does get a urinary tract infection, their symptoms typically worsen.

When to See a Doctor

Contact your healthcare provider if you have ongoing bladder pain or feel an urgent need to urinate frequently. These symptoms should not be ignored, as they may indicate an underlying condition that requires medical attention.

Causes

The root cause of interstitial cystitis remains unclear, though researchers believe multiple factors are involved. Many patients show damage to their bladder’s protective lining, which may allow urine to irritate the bladder wall.

Several other possible factors might contribute to this condition:

  • Autoimmune responses: The body’s immune system may mistakenly attack the bladder.
  • Genetic factors: Family history may increase risk.
  • Bacterial or viral infections: These might trigger symptoms.
  • Allergic reactions: Some people may develop sensitivity to certain substances.

Research continues to investigate these potential causes, but no single factor has been definitively proven.

Risk Factors

Several factors may increase your chance of developing interstitial cystitis:

  • Gender differences: Women receive this diagnosis more frequently than men. When men have similar symptoms, doctors often attribute them to prostate inflammation instead.
  • Age factor: Most people are diagnosed with interstitial cystitis in their 30s or later in life.
  • Connection to other pain conditions: People with interstitial cystitis often have other chronic pain disorders, such as:
    • Irritable bowel syndrome
    • Fibromyalgia

Complications

Interstitial cystitis often leads to several complications that affect daily life:

Physical Effects

  • Decreased bladder volume due to wall stiffening
  • Difficulty holding urine for normal periods

Quality of Life Impact

  • Disruption of work and social activities
  • Frequent bathroom trips are limiting normal routines

Relationship Challenges

  • Strain on personal relationships
  • Difficulties with intimate physical contact
  • Potential avoidance of sexual activity

Mental Health Concerns

  • Chronic pain causes ongoing stress
  • Sleep disruption leading to fatigue
  • Increased risk of developing depression

These challenges frequently establish a recurring cycle. Physical symptoms worsen emotional health, which can then intensify the perception of physical symptoms.
