If you have been living with Crohn’s disease or ulcerative colitis for years, or if you have recently been diagnosed for the first time later in life, you are far from alone. Inflammatory bowel disease (IBD) affects an estimated 40,000 people in Ireland, and a growing number of new diagnoses are occurring in adults over 50. Managing IBD at this stage of life brings its own set of considerations — from medication interactions to cancer screening and maintaining quality of life. This guide offers practical, evidence-informed advice for older adults navigating IBD in Ireland.
TL;DR
- IBD (Crohn’s disease and ulcerative colitis) can be diagnosed at any age — roughly 10–15% of new cases occur in people over 50
- Older adults with IBD face unique challenges including medication interactions, bone health risks, and increased infection susceptibility
- The HSE Chronic Disease Management (CDM) Programme covers structured IBD care through your GP
- Crohn’s & Colitis Ireland (CCI) offers a helpline, the IBDwell app, a No Wait Card, and local support groups nationwide
- Regular colonoscopy surveillance is essential — IBD increases colorectal cancer risk, and BowelScreen should be discussed with your gastroenterologist
What Is Inflammatory Bowel Disease?
IBD is an umbrella term for two chronic autoimmune conditions that cause inflammation in the digestive tract:
Crohn’s disease can affect any part of the gastrointestinal tract, from the mouth to the anus, though it most commonly involves the small intestine and the beginning of the large intestine. Inflammation can occur in patches and may penetrate deep into the bowel wall.
Ulcerative colitis (UC) affects only the large intestine (colon) and rectum. Inflammation is continuous rather than patchy and is limited to the inner lining of the bowel.
Both conditions follow a relapsing-remitting pattern — periods of active disease (flares) alternating with periods of remission. IBD is distinct from irritable bowel syndrome (IBS), which does not involve inflammation or structural damage to the bowel.
IBD Diagnosed Later in Life — What to Know
While IBD is often associated with younger adults, research published in the Lancet Gastroenterology & Hepatology confirms that 10–15% of new IBD diagnoses occur in people over 60. Late-onset IBD can present differently:
- Ulcerative colitis is more common than Crohn’s in older adults
- Symptoms may be milder or attributed to other conditions, leading to delayed diagnosis
- Bloody diarrhoea, unexplained weight loss, persistent abdominal pain, and fatigue should always be investigated — never dismissed as “just ageing”
- Other conditions such as diverticular disease, ischaemic colitis, and colorectal cancer must be ruled out
If you experience a change in bowel habits lasting more than four weeks, see your GP promptly. Early diagnosis leads to better outcomes.
Treatment Considerations for Older Adults
Treating IBD in older adults requires careful balancing. The same medications used in younger patients are generally effective, but the risk profile shifts:
5-ASAs (mesalazine) remain a first-line treatment for mild-to-moderate ulcerative colitis and carry a relatively low side-effect profile. They are generally well tolerated by older adults.
Corticosteroids (such as prednisolone) are effective for managing flares but carry greater risks in older adults, including accelerated bone loss, elevated blood sugar, increased infection risk, and mood disturbance. Your medical team will aim to minimise steroid use and duration.
Immunomodulators (azathioprine, methotrexate) suppress the immune system to maintain remission. In older adults, these medications require more frequent blood monitoring due to increased susceptibility to infections and a slightly elevated risk of certain lymphomas.
Biologic therapies (infliximab, adalimumab, vedolizumab, ustekinumab) have transformed IBD management. Research suggests they are as effective in older adults as in younger patients, though infection risk warrants close monitoring — particularly for tuberculosis screening before starting treatment.
Polypharmacy matters. If you are taking medications for blood pressure, diabetes, heart conditions, or arthritis, ensure your gastroenterologist has a complete list. Drug interactions are a real concern — your community pharmacist can help with a Medicines Use Review (MUR).
Bone Health and IBD
Older adults with IBD face a heightened risk of osteoporosis, driven by chronic inflammation, corticosteroid use, and potential nutrient malabsorption (particularly calcium and vitamin D). A DEXA scan to assess bone density is recommended if you have been on steroids for more than three months or have other risk factors. Your GP can arrange this through the HSE. Weight-bearing exercise, adequate calcium intake, and vitamin D supplementation (particularly important in Ireland’s climate) are essential preventive measures.
Cancer Surveillance
Long-standing IBD — particularly ulcerative colitis affecting a large portion of the colon — increases the risk of colorectal cancer. Current guidelines recommend surveillance colonoscopy every one to three years, depending on your individual risk profile, disease extent, and duration.
This is separate from the national BowelScreen programme, which offers free bowel screening to adults aged 59–69 using a home stool test. If you have IBD, discuss with your gastroenterologist whether BowelScreen is appropriate for you or whether your existing colonoscopy surveillance provides adequate monitoring.
Nutrition and Diet
There is no single “IBD diet,” but nutrition plays a vital role in managing symptoms and maintaining overall health:
- During a flare, a low-residue diet (limiting high-fibre foods) may reduce symptoms
- In remission, a varied, balanced diet rich in fruits, vegetables, lean protein, and wholegrains supports gut healing
- Iron, vitamin B12, folate, and zinc deficiencies are common in IBD — regular blood tests can catch these early
- If you have strictures (narrowing) in Crohn’s disease, certain foods may need to be avoided to prevent blockages
- A referral to an INDI-registered dietitian with experience in IBD is invaluable — ask your gastroenterologist or GP
Crohn’s & Colitis Ireland (CCI) publishes a free recipe book designed for people with IBD, available through their website.
Mental Health and Quality of Life
Living with a chronic bowel condition can take a significant toll on mental wellbeing. The unpredictability of flares, the urgency of symptoms, and the social embarrassment that can accompany IBD all contribute to anxiety and, in some cases, depression. Research from TILDA (The Irish Longitudinal Study on Ageing) consistently highlights the link between chronic illness and psychological wellbeing in older adults.
Do not hesitate to speak with your GP about how IBD is affecting your mental health. Cognitive behavioural therapy (CBT) and mindfulness-based approaches have shown benefit for people with IBD. CCI also offers mental health resources and peer support through their local groups.
Supports Available in Ireland
Crohn’s & Colitis Ireland (CCI) is the national patient organisation for people living with IBD. They offer:
- A helpline (01 531 2983, Mon/Wed/Fri, 09:30–12:30) staffed by trained volunteers
- The IBDwell app for tracking symptoms, medications, and appointments
- A No Wait Card — a discreet card explaining your need for urgent toilet access
- Local support groups across Ireland (Cork, Limerick, and more)
- The GutCAST podcast and educational resources for patients, families, and employers
HSE Chronic Disease Management (CDM) Programme: If you have a medical card or GP visit card, your GP can provide structured reviews for chronic conditions including IBD, at no additional cost.
HSE Living Well Programme: A free six-week self-management course for people living with chronic conditions, available through CCI and local HSE services.
Hospital-based IBD nurse specialists are available at many Irish hospitals and serve as a key point of contact between flare-ups. Ask your gastroenterology team about accessing this service.
Practical Tips for Living Well with IBD After 50
- Keep a flare plan agreed with your medical team — knowing what to do when symptoms worsen reduces anxiety and speeds treatment
- Stay up to date with vaccinations — some IBD medications suppress your immune system, making flu, pneumococcal, and shingles vaccines particularly important. Your GP can advise on timing around immunosuppressant doses
- Plan ahead when travelling — carry a toilet access card, pack extra medication, and bring a letter from your consultant summarising your condition and treatment
- Stay physically active — gentle exercise such as walking, swimming, or yoga can reduce fatigue, improve mood, and support bone health. Listen to your body during flares
- Talk about it — IBD can feel isolating, particularly for older adults who may find it difficult to discuss bowel symptoms. Peer support through CCI or a trusted friend can make a real difference
