Summary:
- Not directly. Cystitis is usually a bladder infection caused by bacteria from poo getting into the urinary tract, and stress isn’t a known cause.
- Stress may make the symptoms of bladder pain syndrome worse. This is a long-term condition, also called interstitial cystitis, that isn’t caused by an infection.
- If you have symptoms, a urine test can show whether there’s a bladder infection. The Better2Know urine culture test gives results in 2 days.
Stress can seem to show up everywhere in the body, so if you keep getting cystitis during a busy or difficult time, it’s natural to wonder whether stress is to blame.
In this blog, we explain what causes cystitis, how it differs from bladder pain syndrome, what the evidence says about stress, and how to find out what’s causing your symptoms.
Does stress cause cystitis?
Not directly. Cystitis is a bladder infection, a type of urinary tract infection (UTI), and it’s usually caused by bacteria from poo getting into the urinary tract. The NHS doesn’t list stress as a cause or a risk.
It’s different for bladder pain syndrome, a long-term condition also known as interstitial cystitis. Research suggests long-term stress can make bladder symptoms worse, especially in bladder pain syndrome and overactive bladder, although it isn’t known how.
What is cystitis?
Cystitis is an infection of the bladder. Symptoms include:
- pain or a burning feeling when you pee
- needing to pee more often, or more suddenly, than usual
- cloudy pee, or blood in your pee
- pain low in your tummy, or in your back just under the ribs
- feeling tired or weak
Things that make it more likely include pregnancy, the menopause, kidney stones, a urinary catheter, an enlarged prostate, a weakened immune system, using spermicide, and not drinking enough fluids. Women get UTIs more easily because they have a shorter urethra. Read more in “Is a UTI caused by sex?”
What is bladder pain syndrome?
Bladder pain syndrome (BPS), also known as interstitial cystitis, is a long-term condition. It isn’t caused by an infection: the lining of the bladder becomes irritated and inflamed, and it isn’t clear why. Symptoms include:
- pain in your bladder, lower tummy or back
- feeling like you need to pee, even when your bladder is empty
- peeing often, usually small amounts, and waking up at night to pee
- pain during sex
It’s more common in women and usually affects people aged 40 or over. Symptoms tend to come and go, with flare-ups. There’s no single test for it, so other causes, such as a UTI, need to be ruled out first.
Stress and your bladder: what the evidence says
Stress isn’t a known cause of bladder infections. What research does suggest is that long-term stress can make bladder symptoms worse in some conditions, particularly bladder pain syndrome and overactive bladder. Anxiety and depression are also more common in people with long-term bladder problems. Much of the research on how this happens comes from animal studies.
For bladder pain syndrome, the NHS says gentle exercise, such as walking, swimming or yoga, and relaxation techniques may help with some symptoms, and support is available if you have low mood or anxiety.
Could it be an STI?
Some STIs cause symptoms that feel like cystitis, such as pain or burning when you pee. These include Chlamydia, Gonorrhoea, Trichomonas, Mycoplasma genitalium and genital Herpes. UK guidance for doctors says to ask about STIs in sexually active people with urinary symptoms.
If you’ve had sex with a new partner, it’s worth testing for STIs as well as a UTI. Read more in “Is a UTI an STI? How to tell the difference”
How to lower your risk of cystitis
To lower your risk of cystitis, the NHS suggests:
- drinking plenty of fluids, particularly water
- peeing as soon as possible after sex
- not holding your pee in when you need to go, and trying to empty your bladder fully
- wiping from front to back after going to the toilet
- not using scented soap around the genitals
- avoiding spermicidal lube on condoms, diaphragms or caps
If you keep getting cystitis, the NHS says there’s some evidence that D-mannose or cranberry products may help. If you take warfarin, avoid cranberry products. Read more in “Does peeing after sex really prevent STIs?”
When to get urgent help
Get urgent medical care if you have symptoms of a UTI and:
- you have a high or very low temperature, or feel hot, cold or shivery
- you have pain in your lower tummy or in your back, just under the ribs
- you have blood in your pee
- you’re a man, or are trans or non-binary and were assigned male at birth
- you’re pregnant
- you’re 65 or older, have diabetes or a weakened immune system, or use a catheter
- your symptoms get worse quickly, or don’t improve within 2 days of starting treatment or treating it yourself
- you keep getting UTIs (2 within 6 months, or 3 within 12 months)
In an emergency, call 999, for example if you feel confused or drowsy, or find it hard to speak.
Which test do you need?
Better2Know offers:

FAQs
Is cystitis an STI?
No, but sex can make it more likely, and some STIs cause similar symptoms.
Can cystitis go away on its own?
Sometimes. A doctor may suggest waiting 48 hours before starting antibiotics, in case your symptoms get better on their own.
Can stress make bladder pain syndrome worse?
Research suggests it can. Long-term stress has been linked with worse symptoms in bladder pain syndrome, although it isn’t known exactly why.
Final thoughts
Stress doesn’t cause bladder infections, but it may make bladder pain syndrome worse, so looking after your wellbeing can help your bladder too. If you have cystitis symptoms, a urine test can show whether there’s an infection, and if you’ve had a new partner, it’s worth checking for STIs as well.
Order a urine culture test or book a Comfort Screen at a clinic near you. Our Patient Care Team is available 24/7 on 020 7099 0955.
