Interstitial cystitis

Overview

Interstitial cystitis (IC) is a long-term condition that causes bladder pain, pressure, and the need to urinate often. The bladder wall becomes irritated or inflamed, but doctors don't always know why.

IC is not very common, but it affects millions of people worldwide. Many cases go undiagnosed because symptoms can be mistaken for other conditions.

IC affects both men and women, but it is much more common in women. It often starts around age 30 to 50, but it can begin at any age.

Symptoms

Common symptoms

• Pain or pressure in the bladder or pelvis
• A strong, frequent need to urinate (sometimes every hour)
• Pain that gets worse as the bladder fills and gets better after urinating
• Pain during sex for women and men

Symptoms in children

• Children with IC may have frequent daytime accidents (wetting) and complain of belly or pelvic pain. They might not be able to describe the pain clearly.

Symptoms in older adults

• In older adults, symptoms may be less typical. They might feel a general sense of pelvic discomfort or have worsening of urinary urgency.

Causes

Main causes

• The exact cause is unknown. It may be a problem with the protective lining of the bladder, an allergic reaction, or nerve signals that become overly sensitive.
• Some people have changes in the bladder wall (called Hunner's lesions) that cause pain and bleeding.

Risk factors

• Being female
• Having another chronic pain condition (such as irritable bowel syndrome or fibromyalgia)
• Having a history of urinary tract infections
• Stress

When to see a doctor

See a doctor urgently if:

• If you have severe pelvic pain that does not go away
• If you see blood in your urine
• If you have a fever along with urinary symptoms

Book a routine appointment if:

• If you have frequent urination or bladder discomfort that lasts more than a few days
• If symptoms interfere with your sleep or daily activities

Diagnosis

There is no single test for IC. Your doctor will ask about your symptoms, do a physical exam, and rule out other conditions like infections or kidney stones.

Tests that may be done

• Urinalysis (testing your urine)
• Cystoscopy (a thin tube with a camera to look inside the bladder)
• Bladder biopsy (taking a small sample of bladder tissue)

What to expect at your appointment

The process may take time because many other conditions have similar symptoms. Your doctor might ask you to keep a diary of when you urinate and when you have pain.

Treatment

Treatment focuses on relieving symptoms because there is no cure. A combination of lifestyle changes, medications, and sometimes procedures can help.

Self-care at home

• Avoid foods and drinks that irritate your bladder, such as coffee, tea, alcohol, spicy foods, and citrus fruits
• Try stress-reduction techniques like deep breathing or gentle exercise
• Use a heating pad on your lower belly to ease pain

Medical treatments

Your doctor may recommend oral medicines to relax the bladder or protect its lining. Bladder instillations (where medicine is put directly into the bladder through a thin tube) can also help. Physical therapy for pelvic floor muscles may be suggested.

When is surgery considered?

Surgery is rarely needed. It is considered only if other treatments have not worked and symptoms are severe. Options include increasing bladder capacity or removing Hunner's lesions.

Living with this condition

Living with interstitial cystitis means managing ups and downs. Some days are better than others. Keeping a symptom diary can help you see what triggers your flares.

Lifestyle tips

• Drink plenty of water to dilute your urine
• Use a bathroom schedule to reduce urgency
• Wear loose, comfortable clothing
• Try relaxation or mindfulness to lower stress

Diet and exercise

Many people find that certain foods trigger their symptoms. A food diary can help you identify your triggers. Gentle exercise like walking or stretching is safe, but high-impact activities might worsen pain.

Mental health and emotional wellbeing

Chronic pain and frequent bathroom trips can affect your mood and social life. It is normal to feel frustrated or anxious. Talking to a counselor can help you cope with these feelings. If you feel overwhelmed, reach out to a mental health crisis line or speak with your doctor.

Prevention

Since the exact cause is unknown, there is no sure way to prevent IC. But early treatment and avoiding known triggers may help prevent flares.

Complications

If left untreated

• Untreated IC can lead to poor quality of life due to constant pain and urgent bathroom needs.
• Bladder scarring or a decrease in bladder capacity over time.

Long-term outlook

IC is a long-term condition, but most people find relief with treatment and lifestyle changes. Many people live active, fulfilling lives with proper management.
