Interstitial cystitis is also known as painful bladder syndrome or bladder pain syndrome. It's more common in women than men.
Symptoms include pain when weeing and needing to wee urgently and often. You may feel pressure, discomfort or pain in your bladder and pain may get worse as your bladder fills up. Certain things may trigger your symptoms (that is, make them worse), such as stress and some foods and drinks.
Treatment for interstitial cystitis aims to relieve your symptoms and there are also things you can do yourself to help reduce them.
The cause of interstitial cystitis isn’t known, but it's not due to an infection in your bladder.
There may be a weakness in the protective lining of your bladder that means toxic substances in your urine can irritate your bladder wall.
Other things that might contribute include infection, inflammation, genetics, allergy or changes in the nerves that sense bladder changes. Sometimes stress or worries can bring on the symptoms of interstitial cystitis as well.
Risk factors for interstitial cystitis include:
your sex – interstitial cystitis is more common in women than men
your age – it’s more often diagnosed in people 30 years of age or older, but it can occur at any age
having another chronic condition – people with interstitial cystitis may have other chronic pain disorders, such as irritable bowel syndrome or fibromyalgia.
The symptoms of interstitial cystitis can differ from person to person and may change from day to day. Symptoms can include:
feeling a strong need to pee (pass urine) right away even if you’ve just passed urine (this is called urinary urgency)
needing to pee more often than usual, sometimes as often as every 10 to 15 minutes (this is called urinary frequency)
discomfort, pressure, tenderness or intense pain in your pelvic area (lower tummy) – this may get worse when your bladder is filling up and then goes away when you empty your bladder
needing to get up during the night more often than usual to pee
pain during sex.
It’s unusual to leak urine if you have interstitial cysitis.
See your healthcare provider urgently if you have pain in your lower tummy or blood in your urine as this may be a sign of a different condition.
Some people have symptom flares (when their symptoms get worse) in response to things including:
stress
having sex
menstruating (having a period)
urinary tract infection
taking certain medicines or forgetting to take medicines
some foods or drinks.
Foods that may make your symptoms worse include:
citrus fruits and juices
tomatoes
chocolate
coffee and caffeinated drinks
alcohol
spicy foods
carbonated drinks (sodas)
acidic foods
artificial sweeteners
preserved foods such as packaged meats.
There’s no single test to diagnose interstitial cystitis. Diagnosis can be difficult because the symptoms of interstitial cystitis can happen with other conditions, such as chronic urinary tract infections, prostatitis and endometriosis. Your healthcare provider will need to exclude these based on your history and investigations.
Your healthcare provider will ask you about your symptoms and may ask you to keep a bladder diary where you record the amount of fluids you drink and the amount of urine you pass/pee out. The types of questions your healthcare provider may ask include:
How often do you feel the urge to pee with little or no warning?
Do you feel the urge to pee straight after you’ve been to the toilet to pass urine?
Do you ever have to pee less than 2 hours after you finished peeing?
Do you have to get up at night to pee?
Do you have pain or burning in your bladder area (lower tummy)?
They will also do a pelvic exam (examination of your external genitals, and vagina and cervix in females) and feel your tummy to check your internal pelvic organs (bladder, uterus). They may also examine your bottom (anus and rectum).
You’ll be asked to give a sample of your urine/pee so that a urinary tract infection can be ruled out.
You may need more tests including:
Cystoscopy – where a small telescope is used to look inside your bladder. If a biopsy is needed (where a small piece of tissue is taken from your bladder) you will usually be given a general anaesthetic for the cystoscopy.
Urodynamic testing to test the function of your bladder and urethra (the tube that lets urine travel from your bladder to the outside of your body).

There's no single treatment that works for everyone with interstitial cystitis. Treatment aims to relieve your symptoms and it may take weeks to months before your symptoms improve.
Your healthcare provider will create a treatment plan for you that may include some of the approaches described below. You may need a combination of these and, even then, your symptoms may come and go. However, over time you should be able to find treatments that give you relief and help you cope with interstitial cystitis.
Lifestyle changes See the self-care section below for things you can do to help manage your symptoms.
Bladder training Keep a bladder diary to record how often you pee and how often you have the urge to pee. You can then use this to train yourself to hold in your pee for longer periods so that you can gradually increase the time between bathroom visits. See the resources in the more information section below for examples of bladder diaries.
Bowel training Some people find their interstitial cystitis symptoms improve if they have regular bowel movements, so it may help if you can train yourself to have a bowel movement (poo) at the same time each day.
Physiotherapy A physiotherapist who specialises in pelvic floor muscles (the muscles between your pubic bone at the front and your tail bone at the back) can work with you to stretch these muscles and teach you how to keep them relaxed. This may help reduce any pelvic floor tenderness.
Other non-medicine pain treatments Treatments such as acupuncture or transcutaneous electrical nerve stimulation (TENS), may be helpful.
Counselling Professional counselling can help you learn ways to cope with your pain and any stress and anxiety that may be contributing to, or caused by, your symptoms. If you have other stress or worries in your life, such as work, study, money-problems or relationship issues, counselling can be very helpful and can have a positive impact on your interstitial cystitis symptoms as well.
Oral medicines Although there isn’t any definite evidence that these work for interstitial cystitis, some people find these medicines helpful:
Antihistamines, which can block the effect of histamine in the bladder if your symptoms might be due to an allergic reaction.
Bladder procedures Procedures that may help include:
ladder instillation where medicines, such as dimethyl sulfoxide (DMSO), steroid or a numbing medicine, are placed into your bladder through a thin tube called a catheter
cytoscopy with bladder stretching (where your bladder is filled with water), which may temporarily relieve symptoms and may also detect ulcers that can be treated
botulinum toxin (Botox) injections into the bladder
neuromodulation therapy which uses harmless electrical impulses to change how the nerves going to and from your bladder work.
Supplements and herbal medicines Supplements that may help you manage your symptoms include calcium glycerophosphate, glucosamine, chondroitin, quercetin complex, or aloe capsules.
Surgery Bladder surgery is only considered if other treatments don’t provide symptom relief.
Keep a food diary and avoid any foods or drinks that trigger your symptoms.
Try an elimination diet(external link). This is where you stop eating foods that could trigger your symptoms and then reintroduce each food one by one and note whether your symptoms return. This should be done with supervision from your healthcare provider or a dietician.
Your healthcare provider may recommend taking an antacid with meals if you notice that your symptoms get worse with acidic foods or drinks such as citrus fruits, peppers, carbonated drinks or tomatoes.
Avoid smoking. The chemicals in cigarettes can irritate your bladder, and even if smoking doesn’t trigger your symptoms, it’s a major cause of bladder cancer so stopping smoking is a good decision.
Be active. Even easy activities like walking or gentle stretching can help relieve symptoms.
Try relaxation techniques, such as mindfulness, as stress can trigger symptoms in some people.
Put an ice-pack or heat pad on your lower tummy or perineum. Your perineum is the area between your genitals (scrotum in males and vulva in females) and the opening of your rectum (anus).
Take a warm sitz bath. This is a shallow warm water bath that you sit in to relieve pain in your perineum. Read more about sitz baths(external link).
Relax your pelvic floor muscles by squatting with your legs wide apart.
Try the ‘happy baby’ yoga pose. Lie on your back, press your knees against your chest, point the bottoms of your feet towards the ceiling and grab the outsides of your feet. See the image below.
Avoid tight clothes that press on your tummy.
If sex makes your symptoms worse, you can take pain killers beforehand and use lubricants during sex to reduce discomfort.
Reach out for support from family and friends and other people with interstitial cystitis.
Some people find their interstitial cystitis symptoms get better over time and may even disappear completely with treatment. However, for many people, the symptoms come and go and treatment is needed on and off throughout their life. To help stop your symptoms coming back, it’s a good idea to continue your treatment plan even when you feel better.
Most people with interstitial cystitis can get good relief from their symptoms and live well once their pain is managed effectively with a combination of treatment approaches that have been specifically chosen for them.
