Inflammatory bowel disease (Crohn's / colitis) management

The long-term medical care used to control inflammation in Crohn's disease and ulcerative colitis, aiming to settle flares, keep the bowel in remission and reduce complications.

In short

IBD (Crohn's disease and ulcerative colitis) is long-term inflammation that genuinely damages the bowel, unlike irritable bowel syndrome.
Management has two stages: settling a flare and then keeping the bowel in remission, with treatment stepped up or down by a specialist team.
Medicines range from aminosalicylates and steroids to immune-modifying and biologic therapies; steroids are for short-term flare control, not long-term use.
Long-term monitoring matters — for medicine side effects, nutrition, bone and bowel-cancer risk, and the right vaccinations.

What is inflammatory bowel disease (IBD) management?

Inflammatory bowel disease (IBD) means Crohn's disease and ulcerative colitis: long-term conditions where the immune system causes inflammation in the gut. This leads to symptoms such as diarrhoea, often with blood, tummy pain, urgency, tiredness and weight loss, in flares that come and go.

Unlike irritable bowel syndrome, IBD genuinely damages the bowel lining and, over time, can cause complications. So management has two aims: to settle a flare (induce remission) and then to keep the bowel calm and prevent further flares (maintain remission), while monitoring for problems.

Treatment is led by a specialist IBD team and stepped up or down depending on how active and severe the disease is. Options range from aminosalicylates and steroids to immune-modifying medicines and biologic or other targeted therapies, with surgery for some people. Diet, smoking (which worsens Crohn's), vaccinations and monitoring all play a part.

IBD cannot usually be cured with medicine, but with the right plan many people achieve long periods of good health. The goal is lasting remission with the least treatment needed, not just masking symptoms.

Types, options & approaches

There may be different ways to do this. The right approach depends on the clinical question and your circumstances.

Aminosalicylates (5-ASA)

Such as mesalazine. A mainstay for mild to moderate ulcerative colitis, used to settle flares and keep them away. Less effective in Crohn's disease. Very rarely, mesalazine has been linked to raised pressure inside the skull (called idiopathic intracranial hypertension). Tell your doctor if you have ever had this or it has been suspected, and let them know promptly if you develop a new, worsening or recurring headache, changes in your vision, a whooshing sound in the ears, dizziness or neck or back pain — particularly if these happen together.

Steroids

Such as prednisolone or budesonide. Used in courses to bring an active flare under control. They are not for long-term use because of side effects, and are not a maintenance treatment.

Immunomodulators

Such as azathioprine, mercaptopurine or methotrexate. These calm the immune system to keep disease in remission and reduce reliance on steroids. They need regular blood-test monitoring.

Biologic and targeted therapies

Such as anti-TNF and other biologics, or newer tablet therapies, for moderate to severe disease or when other treatments fail. Covered in more detail in the separate biologics guide.

Surgery

Some people with ulcerative colitis or Crohn's need an operation — for example to remove a badly affected segment, or the colon in severe colitis. It is part of care, not a failure.

Diet, lifestyle and supportive care

Stopping smoking (important in Crohn's), correcting deficiencies (such as iron), nutritional support, bone protection, vaccinations and emotional support all form part of management.

Crohn's disease vs ulcerative colitis

Feature	Ulcerative colitis	Crohn's disease
Where	Colon (large bowel) lining	Anywhere from mouth to anus
Pattern	Continuous from the rectum upward	Patchy, can skip areas
First-line drugs	Aminosalicylates often used	Aminosalicylates less effective
Smoking	Often less active in smokers (but stopping is still advised)	Clearly worsens the disease

Both are forms of IBD; treatment is tailored by type, site, severity and how you respond.

Preparing for your treatment

Bring a clear history of your symptoms, flares and any previous treatments and operations.
Have a full list of current medicines, supplements and allergies ready.
Ask about screening before immune-modifying or biologic treatment (such as infections and vaccination status).
Check your vaccinations are up to date, as some live vaccines must be given before starting certain treatments.
If you smoke, ask for help to stop, especially with Crohn's disease.
Discuss plans for pregnancy, as this affects choice and timing of treatment.
Agree how flares will be managed and who to contact urgently.

What happens

Management begins with confirming the diagnosis and assessing how active and extensive the disease is, using a combination of symptoms, blood tests, stool tests such as faecal calprotectin, endoscopy and scans.

When the disease is active, treatment is aimed at settling the flare — for example a course of steroids, or starting or adjusting other medicines. As things improve, the focus shifts to maintenance treatment to keep the bowel calm with as little medicine as possible, often an aminosalicylate, immunomodulator or biologic depending on the type and severity.

You are then followed up by the IBD team, with regular reviews, blood tests and monitoring. Treatment is stepped up if disease flares or stepped down if you stay well. Surgery is discussed when medicines are not enough or complications develop, and you should have a named contact, often an IBD nurse, for advice and flares.

Is this treatment right for me?

A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.

May not be suitable if…

Long-term steroid use as a maintenance strategy, because of cumulative side effects.
Starting immune-modifying or biologic treatment without first screening for infections.
Managing severe flares at home when urgent hospital assessment is needed.
Treating as IBD without confirming the diagnosis when symptoms could be another condition.

Delay or rearrange if…

There is an active infection that needs treating before stepping up immune-suppressing therapy.
Vaccinations, particularly live vaccines, are needed before certain treatments start.
You are pregnant or planning pregnancy and treatment choice needs review.
Screening tests before biologics or immunomodulators are incomplete.

Alternatives to discuss

Different classes of medicine if the first does not work or is not tolerated.
Surgery when medicines do not control disease or complications develop.
Nutritional therapy, particularly in some children and young people with Crohn's.
Clinical trials of newer treatments in selected cases.
Supportive care and symptom control alongside disease-modifying treatment.

Before you decide

Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.

What matters most to me?

Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.

What are all my options?

Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.

What would make me pause?

Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.

What happens if I do nothing today?

For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.

Benefits

Settling flares so symptoms such as bleeding, pain and urgency improve.
Keeping the bowel in remission for long periods in many people.
Reducing the need for repeated steroid courses and their side effects.
Lowering the risk of complications and some operations when disease is well controlled.
Monitoring that catches problems early, including nutrition, bone health and bowel-cancer risk.
Support to live a fuller, more predictable life between flares.

Risks & complications

More common

Side effects from medicines, such as those from steroid courses
Flares that recur despite treatment, sometimes needing a change of medicine
The need for regular blood tests and monitoring
Tiredness, anaemia or low mood related to active disease

Less common

Infections, especially on immune-modifying or biologic treatment
Treatment that stops working over time and needs switching
Nutritional deficiencies or bone thinning, particularly with repeated steroids
Needing surgery if medicines do not control the disease

Rare but serious

Serious infections or, with some immune-suppressing treatments, a small increased risk of certain cancers
Severe flares needing emergency hospital care
Complications such as bowel narrowing, abscess or perforation
Very rarely, the 5-ASA medicine mesalazine has been linked to raised pressure around the brain (idiopathic intracranial hypertension), which can cause headache and visual problems

The biggest issues in IBD management are balancing disease control against the side effects of treatment, and not relying on steroids long term. Immune-modifying and biologic treatments raise infection risk and need screening and monitoring. Ask your team how each treatment will be monitored, what side effects to watch for, how bowel-cancer surveillance is arranged, and who to contact urgently in a flare.

Published figures to discuss

There is no single success rate for IBD management, because outcomes depend on the type and severity of disease, the treatment used, and the individual. Remission rates, side effects and the chance of needing surgery vary widely between studies and over time, and some treatments lose effect, so quoting exact percentages can mislead. Risks of infection and other side effects are explained for the specific treatments in your plan, especially for biologics and immunomodulators.

Figure	Reported range	How to interpret it	Source / confidence
Remission or good control	Highly variable by Crohn's vs ulcerative colitis, disease severity and treatment	Patients should be told what target is being used: symptom control, normal blood/stool markers, mucosal healing, steroid-free remission or prevention of flares.	Guide sourcesClinical context
Serious infection on infliximab/anti-TNF therapy	Older infliximab trial data reported serious infections in about 3-4%; real-world risk depends strongly on steroids, other immunosuppression and frailty	The practical consent point is screening, vaccination review and avoiding biologic dosing during significant active infection.	Risks and benefits of biologic therapy for inflammatory bowel diseases — PMCpmc.ncbi.nlm.nih.govPublished figure
Steroid-related harm	Common with repeated or prolonged courses	Steroids are useful for induction but are not maintenance treatment. A patient needing repeated steroids needs treatment escalation review.	Guide sourcesClinical context
Need for surgery	Meaningful minority over a disease lifetime; varies widely	Surgery is not failure in every case. It should be discussed early when disease is stricturing, fistulising, refractory or when cancer risk changes the balance.	Risks and benefits of biologic therapy for inflammatory bowel diseases — PMCpmc.ncbi.nlm.nih.govSource-linked context
Colorectal cancer surveillance	Risk depends on duration, extent, inflammation burden, PSC and family history	Patients with colitis should know whether and when they enter a surveillance-colonoscopy programme.

These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.

What happens afterwards

IBD is managed as a long-term condition rather than cured. After starting or changing treatment, a flare usually settles over days to weeks, and staying in remission is judged over months, with ongoing monitoring throughout.

During a flare

Treatment such as a steroid course is started to settle inflammation. Symptoms often improve over days to a couple of weeks; severe flares may need hospital care.

Early weeks

As the flare settles, maintenance treatment is started or adjusted to keep the bowel calm, with blood tests to check safety and response.

Months

The aim is steady remission on the least treatment needed. Steroids are tapered off, and response is checked with symptoms, blood and stool tests, and sometimes endoscopy.

Long term

Regular reviews continue, treatment is stepped up or down as needed, and surveillance for complications and bowel-cancer risk is arranged according to your situation.

What's normal — and not a worry

Gradual improvement of a flare over days to weeks rather than instantly
Tiredness that lingers for a while after a flare settles
Periods of good health (remission) interrupted by occasional flares
Regular blood tests becoming a normal part of life on certain treatments

Aftercare

Take maintenance treatment as prescribed, even when you feel well, to prevent flares.
Attend blood-test monitoring for immune-modifying and biologic treatments.
Do not stop steroids suddenly — they must be reduced gradually under guidance.
Keep vaccinations up to date as advised, avoiding live vaccines on certain treatments.
If you smoke, get support to stop, especially with Crohn's disease.
Use your IBD nurse or team contact early in a flare rather than waiting.
Attend agreed surveillance, such as colonoscopy, to monitor long-term risks.

Before your treatment

Up-to-date medicine list and monitoring schedule
Vaccination status reviewed before immune-modifying treatment
IBD nurse or team contact details saved
Plan agreed for what to do in a flare
Smoking-cessation support if relevant
Surveillance (e.g. colonoscopy) dates noted

⚠ Get urgent help if…

Severe tummy pain or a swollen, tender abdomen
Heavy or persistent rectal bleeding
High fever or feeling very unwell, especially on immune-suppressing treatment
Persistent vomiting or being unable to keep fluids down
Many bloody stools a day with dehydration or a racing heart
Signs of infection while on biologics or immunomodulators
While taking mesalazine: a new, worsening or recurring headache with visual disturbance, a whooshing sound in the ears, dizziness or neck or back pain — especially together — as this can rarely signal raised pressure around the brain and needs prompt medical review
These can signal a severe flare or complication and need urgent assessment

Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

General guidance — it doesn't replace the specific advice your specialist gives you.

Results & realistic expectations

A good result in IBD is lasting remission — the bowel calm, symptoms controlled, and life close to normal — achieved with the least treatment needed and without repeated steroid courses. Healing of the bowel lining, not just feeling better, is increasingly the target, as it is linked to fewer complications.

Medicine cannot usually cure IBD, and flares can return even with good treatment. Response varies between people and between drugs, and some treatments lose effect over time and need switching. The aim is durable control and fewer complications, not a guarantee that the disease will never return.

How long it lasts

IBD is usually lifelong, with a course that varies from person to person. Many people have long stretches of remission, while others need treatment changes or surgery over the years. Treatment is reviewed regularly and adjusted as the disease and your circumstances change, and long-term surveillance for complications and bowel-cancer risk continues.

Related tests, treatments or support

IBD management often combines several elements: medicines to control inflammation, supportive care such as iron for anaemia and bone protection, vaccinations, and surveillance. It works alongside tests like faecal calprotectin, colonoscopy and scans to monitor activity, and may involve surgeons, dietitians and IBD nurses as part of a team.

Follow-up & long-term care

You should be under a specialist IBD team with regular reviews, monitoring blood tests, and a named contact such as an IBD nurse for flares. Follow-up includes checking treatment is working and safe, keeping vaccinations current, and arranging bowel-cancer surveillance and other monitoring appropriate to your disease.

Taking maintenance medicines consistently to prevent flares
Regular blood-test monitoring on immunomodulators and biologics
Keeping vaccinations up to date and avoiding live vaccines where contraindicated
Bone-health and nutritional checks, especially after repeated steroids
Bowel-cancer surveillance (such as colonoscopy) at intervals set by your team
Stopping smoking, particularly in Crohn's disease

Repeat, follow-on and what comes next

Treatment is commonly stepped up, stepped down or switched as the disease changes.
Some medicines lose effect over time and need changing.
Surgery may become part of care for some people, and is not a failure of management.
Flares can recur despite good treatment, prompting reassessment rather than alarm.

Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.

What good aftercare looks like

A specialist IBD team with a named contact, often an IBD nurse, for advice and flares.
Clear monitoring for treatment safety, nutrition and bone health.
Vaccination review and bowel-cancer surveillance arranged appropriately.
A written plan for maintenance treatment and for managing flares.

What affects the cost

Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:

How active and complex the disease is, and how often reviews are needed
The type of medicines used, including immunomodulators and biologics
Blood-test and other monitoring required for certain treatments
Endoscopy and imaging used to assess and monitor disease
Input from IBD nurses, dietitians and, where needed, surgeons
Long-term surveillance such as colonoscopy

Make sure your written quote includes

What consultations, monitoring and IBD nurse support are included
How medicines, including biologics, are arranged and funded
Whether blood-test monitoring is included or charged separately
Whether endoscopy and imaging are included
How flares and urgent reviews are handled out of hours
How long-term surveillance (such as colonoscopy) is arranged

On the NHS? IBD is mostly managed on the NHS by specialist teams, including complex treatments and biologics; private care is also available, sometimes for faster access to consultations and monitoring.

Frequently asked questions

Can IBD be cured?

Medicines do not usually cure IBD, but they can control it well, giving many people long periods of remission. Surgery can remove diseased bowel and, in ulcerative colitis, removing the colon can stop that disease, though it has major consequences.

Why can't I just stay on steroids?

Steroids are very useful for settling a flare but cause significant side effects with long-term use and do not keep IBD in remission. They are used in short courses, with other medicines used for maintenance.

How is IBD different from IBS?

IBD (Crohn's and colitis) is inflammation that genuinely damages the bowel and can cause complications. IBS is a disorder of how the gut works and does not damage it. They can feel similar, which is why tests are used to tell them apart.

Will I need surgery?

Many people never do, but some need an operation if medicines do not control the disease or if complications develop. Surgery is part of care, not a sign of failure, and your team will discuss it with you.

Is IBD managed on the NHS?

Yes — IBD is mostly managed on the NHS by specialist teams, usually including an IBD nurse. Private care is also available, sometimes for quicker access, though complex care and biologics are commonly delivered through the NHS.

Can I still have children?

Many people with IBD have healthy pregnancies. It is best to plan ahead, ideally conceiving when the disease is well controlled, and to discuss which treatments are suitable before and during pregnancy with your team.
