IBS Consultation Online — Ireland
Irritable bowel syndrome assessed and managed online — diagnosis support, dietary plan, and antispasmodic / laxative prescribing where appropriate.
About IBS (irritable bowel syndrome)
Irritable bowel syndrome is a common functional gastrointestinal disorder affecting around 1 in 10 adults in Ireland, with women approximately twice as commonly affected as men. It causes recurrent abdominal pain, bloating, and altered bowel habit without identifiable structural disease on investigation. While not life-threatening, IBS can significantly affect quality of life — and there are evidence-based treatments that genuinely help.
Symptoms and signs
- Abdominal pain or cramping — often relieved by defaecation
- Bloating and visible abdominal distension
- Altered bowel habit — diarrhoea (IBS-D), constipation (IBS-C), or mixed (IBS-M)
- Sensation of incomplete evacuation
- Mucus in stools (not blood)
- Symptoms worsened by stress or specific foods
- Often associated with bloating, fatigue, and disrupted sleep
Causes and contributing factors
IBS is multifactorial per NICE CKS: altered gut motility, visceral hypersensitivity (gut nerves register normal sensations as painful), gut-brain axis disruption, gut microbiome changes, post-infectious onset (after a gastroenteritis episode), and triggers including stress, specific foods (FODMAPs), and hormonal changes. Family history is common but no single gene is responsible.
When to seek help — red flags ("alarm symptoms")
Most IBS is well-managed in primary care. An Online Doctor consultation is appropriate for: typical symptoms in an otherwise well adult under 50, support with dietary management, or symptom control with medications. Seek same-day or urgent in-person review for any "red flag" symptoms per NICE: rectal bleeding, unintended weight loss, persistent diarrhoea, abdominal mass, family history of colorectal cancer or inflammatory bowel disease, new symptom onset after age 50, anaemia, or nocturnal symptoms (waking from sleep). These need exclusion of organic disease before an IBS diagnosis.
Treatment options
Per NICE and ICGP guidance, treatment is symptom-targeted:
- Dietary modification — low-FODMAP diet under dietitian guidance has the strongest evidence for symptom relief; modest improvements with reducing caffeine, alcohol, and processed foods
- Antispasmodics — mebeverine, peppermint oil capsules — for cramping pain
- Anti-diarrhoeals — loperamide for diarrhoea-predominant IBS
- Laxatives — for constipation-predominant IBS (avoid lactulose, which worsens bloating); macrogol or osmotic agents preferred
- Probiotics — some patients benefit; suggested 4-week trial
- Low-dose tricyclic antidepressants — for pain and gut hypersensitivity in chronic cases (off-label, well-established practice)
- Cognitive behavioural therapy (CBT) — particularly gut-directed CBT has good evidence
Self-care and lifestyle
Keep a symptom and food diary for 2–4 weeks to identify personal triggers. Eat regular meals — don't skip. Drink plenty of fluids. Limit caffeine and alcohol. Manage stress with mindfulness, exercise, or CBT. The low-FODMAP diet is effective but should be undertaken with a dietitian (it's not a permanent diet — it's a structured elimination-and-reintroduction protocol).
Frequently asked questions
Is IBS the same as inflammatory bowel disease (IBD)?
No. IBS is a functional disorder — the bowel looks normal on investigation but functions abnormally. IBD (Crohn's disease, ulcerative colitis) involves visible inflammation, can cause blood in stools, and requires different specialist-led treatment. Red-flag symptoms should always prompt evaluation to distinguish these conditions.
Will I always have IBS?
IBS is typically a long-term condition but symptom severity often fluctuates over years. Many people achieve excellent control with the right combination of dietary changes, stress management, and selective medication. Some find symptoms improve significantly with age.
Could it be cancer?
IBS doesn't cause cancer. However, certain symptoms can overlap with bowel cancer (especially in those over 50 with new-onset changes). The red-flag list above exists specifically to ensure cancer is excluded when appropriate. BowelScreen (HSE) offers free screening for ages 59–69.
Can probiotics help?
The evidence is mixed but some patients benefit. A 4-week trial of a specific product is reasonable. If no improvement, stop. There's no single "best" probiotic.
