Diagnosing And Treating Interstitial Cystitis

Overview

Interstitial cystitis (IC) is a long-term condition that causes pain around the bladder and a strong, frequent need to pee. Some doctors call it bladder pain syndrome. It is not caused by an infection, and it is not passed to other people. The bladder wall can feel sore and irritated, and the nerves around it can become extra sensitive. Symptoms often come and go in waves called flares, with calmer spells in between.

It is more common than many people think, and it affects women far more often than men. Exact numbers are hard to pin down because it is often missed or mistaken for repeated urine infections or an overactive bladder.

It can affect anyone, but it is most often found in women in their 30s and 40s. Men and children can get it too. People who already have other long-term pain conditions, such as fibromyalgia or irritable bowel syndrome, seem more likely to develop it.

Symptoms

Common symptoms

• Pain, pressure or discomfort in the lower belly, pelvis or bladder area
• Needing to pee very often, sometimes in small amounts
• A sudden, urgent need to pee that is hard to hold
• Waking up several times at night to pee
• Pain that gets worse as your bladder fills and eases a little after you pee
• A burning or stinging feeling when you pee
• Pain during or after sex
• Symptoms that flare up for days or weeks, then settle down

Symptoms in children

• Tummy ache or lower belly pain that keeps coming back
• Peeing very often during the day, or wetting during the day after being dry
• Wetting the bed at night
• Holding on and crossing legs to avoid peeing because it hurts
• Sometimes no clear bladder pain, just repeated 'urine infections' that tests do not confirm

Symptoms in older adults

• Symptoms may be put down to ageing or 'just an overactive bladder' and not looked into
• Sudden strong urges that make it hard to reach the toilet in time
• More night-time trips to the toilet, which can disturb sleep and raise the risk of falls
• Repeated courses of antibiotics for suspected infections when tests are negative
• Pain may be felt as general lower tummy discomfort rather than sharp bladder pain

Causes

Main causes

• The exact cause is not known. Experts think several things may play a part rather than one single cause.
• The protective lining of the bladder may be thinner or damaged, so urine irritates the bladder wall.
• The nerves in and around the bladder may become over-sensitive, so normal fullness feels painful.
• There may be a mild, ongoing inflammation involving cells that release irritating chemicals (mast cells).
• The immune system may react in an unusual way, which is why some people also have allergies or other pain conditions.
• A past injury, surgery or repeated bladder problems may sometimes start the process.

Risk factors

• Being a woman, especially between the ages of 30 and 50
• Having another long-term pain condition such as fibromyalgia, irritable bowel syndrome or chronic fatigue
• A history of repeated urine infections or bladder surgery
• A family member with similar bladder problems
• Long-term stress, which can make symptoms feel worse even if it does not cause the condition

When to see a doctor

See a doctor urgently if:

• You see blood in your urine
• You have a fever, chills, back pain or vomiting
• You are unable to pee at all
• The pain becomes severe or suddenly much worse

Book a routine appointment if:

• You have had bladder pain or a frequent, urgent need to pee for more than a few weeks
• Urine tests keep coming back clear but your symptoms carry on
• You are waking several times a night to pee and feel worn out
• Symptoms are affecting your work, sleep, sex life or mood
• Antibiotics for a 'bladder infection' have not helped

Diagnosis

There is no single test that proves you have IC. Your doctor will start by asking about your symptoms, how often you pee, what makes the pain better or worse, and how it affects your life. They will check your urine to rule out infection and other common causes, and they may ask you to keep a bladder diary for a few days. The diagnosis is usually made once other conditions have been reasonably ruled out.

Tests that may be done

• Urine test and urine culture to look for infection
• A bladder diary: a record of what and how much you drink, how often you pee, and when pain happens
• A physical examination of your tummy and pelvis
• Blood tests to check for other conditions
• A swab or urine test for sexually transmitted infections if there is any chance they could be the cause
• An ultrasound scan of your bladder and kidneys
• Cystoscopy: a thin tube with a camera looks inside the bladder, usually done by a specialist when the diagnosis is unclear or other problems need to be ruled out
• Bladder stretching under anaesthetic (hydrodistension), which can help confirm the diagnosis and sometimes eases symptoms for a while
• Specialist bladder pressure tests (urodynamics), used only in some cases

What to expect at your appointment

Getting a firm answer can take a few appointments, and that can feel frustrating. Keep your bladder diary with you and write down your questions between visits. It helps to bring someone with you if you feel nervous, and it is always fine to ask your doctor to explain anything you did not follow. If your symptoms are not settling, ask whether a referral to a bladder or urology specialist would be sensible.

Treatment

There is no single cure that works for everyone, but most people find their symptoms improve when self-care and medical treatment are combined. Treatment usually starts with the gentlest, lowest-risk steps and builds up over time. Because IC affects people differently, it often takes some trial and error to find what works for you.

Self-care at home

• Keep a food and drink diary to spot things that trigger flares, then try cutting those out for a few weeks, one at a time
• Cut back on caffeine, alcohol, fizzy drinks, citrus fruit, spicy food, tomatoes and artificial sweeteners if they seem to set you off
• Drink enough water through the day, in steady amounts rather than large gulps
• Try bladder training: gently build up the time between trips to the toilet, using relaxing breathing to ride out the urge
• Use a warm pack or heat pad on your lower tummy for pain
• Wear loose clothing and avoid tight waistbands
• Learn pelvic floor relaxation, not just tightening — a tight pelvic floor can keep pain going
• Stop smoking, as smoking irritates the bladder
• Manage stress with breathing exercises, gentle activity or talking therapies

Medical treatments

Doctors may offer treatments that calm the bladder nerves or reduce irritation and inflammation, taken as tablets or capsules. Some medicines are designed to coat and protect the bladder lining. Another option is a bladder instillation, where a liquid medicine is passed into the bladder through a thin tube and held there for a short time. Specialist physiotherapy can help relax tight pelvic floor muscles. Some people are helped by electrical nerve stimulation techniques or by treatments for pain and sleep. If you also have another condition such as irritable bowel syndrome or depression, treating that too often helps bladder symptoms. Your doctor or pharmacist will talk you through the options, their benefits and possible side effects, and you should always follow their advice rather than starting anything yourself. Never take leftover antibiotics, since they will not help IC.

When is surgery considered?

Surgery is rare and only considered when other treatments have not helped and symptoms are seriously affecting your life. Options a specialist may discuss include treating small sore patches (ulcers) in the bladder with heat or laser, stretching the bladder under anaesthetic, or, in a very small number of severe cases, bigger operations. These are big decisions, so ask for a full discussion of benefits and risks, and it is reasonable to ask for a second opinion.

Living with this condition

Living with bladder pain can be tiring, and planning ahead helps. Know where the toilets are when you go out, carry a spare pair of underwear and pads if leaking worries you, and build rest into busy days. Flares usually pass, so it helps to have a small 'flare plan' ready: warmth, bland drinks, gentle movement, pain relief your doctor has advised, and permission to rest.

Lifestyle tips

• Eat regular meals and keep a note of foods that seem to trigger flares
• Choose gentle, regular movement such as walking, swimming or stretching
• Try pelvic floor relaxation and breathing exercises, and consider seeing a pelvic health physiotherapist
• Protect your sleep: limit drinks in the two hours before bed and keep the bedroom cool and dark
• Be open with partners about pain during sex, and plan times when you feel better and are relaxed
• Take care with scented soaps, bubble baths and harsh laundry products, which can irritate sensitive skin
• Reduce or stop smoking, and keep alcohol within low levels or avoid it if it triggers you

Diet and exercise

There is no special IC diet that suits everyone. The most common triggers are caffeine, alcohol, citrus, fizzy drinks, spicy food, tomatoes and artificial sweeteners, so try removing one at a time for a few weeks and see how you feel. A dietitian can help you do this safely without cutting out too much. Gentle exercise is good for pain, mood and sleep — walking, swimming, cycling and yoga are good choices. If exercise makes pain worse, a pelvic health physiotherapist can suggest a gentler approach.

Mental health and emotional wellbeing

Long-term pain and constant trips to the toilet can wear you down, and it is very common to feel anxious, low or isolated. This is a normal response to a difficult condition, not a sign of weakness, and help is available. Talking therapies, relaxation and support groups all make a real difference. If you ever feel you might harm yourself, contact your local emergency number or a crisis line straight away, or ask someone to stay with you while you get help.

Prevention

There is no proven way to prevent interstitial cystitis, because the exact cause is not known. What you can do is reduce how often flares happen by knowing your triggers, drinking enough water, not holding on too long, managing stress, and getting bladder symptoms checked early rather than living with them for months.

Screening programmes

There is no screening test for IC. If you have ongoing bladder pain, frequent urination or repeated 'infections' that urine tests do not confirm, ask your doctor for a review rather than waiting.

Complications

If left untreated

• Ongoing pain and poor sleep, which can leave you exhausted
• Anxiety, low mood or feeling isolated
• Avoiding social events, travel or work because of toilet needs
• Difficulties with sex and relationships
• The bladder may hold less urine over time in some people
• Repeated courses of antibiotics for suspected infections that are not really there

Long-term outlook

The outlook is better than many people expect. IC is a long-term condition, but most people find a combination of self-care and treatment that eases their symptoms, and many improve over time. Symptoms tend to come in flares with calmer periods in between. Getting a clear explanation, a plan you understand and the right support makes a real difference, and it is always worth going back to your doctor if things are not improving.
