Treatment of Irritable Bowel Syndrome (IBS)
IBS is a functional gastrointestinal disorder causing recurrent abdominal pain related to defecation, with altered stool frequency or consistency. It affects up to 15% of the population; dietary changes, stress management, and symptom-specific medications help.
Managing Irritable Bowel Syndrome (IBS) effectively requires a combination of medical treatment, lifestyle modification, and regular monitoring. With a structured management plan, most people with Irritable Bowel Syndrome (IBS) can maintain a good quality of life and prevent serious complications.
First-Line Treatment Principles
- ✓PPI as cornerstone for acid-related disorders (GERD, peptic ulcer, H. pylori eradication regimens)
- ✓H. pylori eradication: PPI + clarithromycin + amoxicillin (7–14 days); bismuth quadruple if resistance suspected
- ✓IBD: 5-ASA for mild UC; corticosteroids for induction; biologics (anti-TNF, anti-integrin) for moderate-severe
- ✓Hepatitis B/C: antiviral therapy (tenofovir/entecavir for HBV; DAAs for HCV with >95% SVR rate)
- ✓Cirrhosis: treat underlying cause + complications (ascites, varices, HE) systematically
What to Do Now
- Learn your personal risk factors for Irritable Bowel Syndrome (IBS) (family history, age, lifestyle)
- Attend regular health check-ups and screening tests appropriate for your age and risk
- Track new or changing symptoms, especially those associated with Irritable Bowel Syndrome (IBS)
- Use our AI symptom checker to assess whether your symptoms fit an early Irritable Bowel Syndrome (IBS) pattern
- Discuss preventive strategies and early monitoring with your GP
- Build a personalised management plan with your GP or specialist
- Adhere consistently to prescribed medications — do not stop without medical advice
- Adopt a Irritable Bowel Syndrome (IBS)-appropriate diet (anti-inflammatory, low-glycaemic, or disease-specific)

Senna is used to treat constipation or diarrhea by modifying bowel motility or intestinal fluid balance.
Docusate is used to treat constipation or diarrhea by modifying bowel motility or intestinal fluid balance.
Prucalopride is used to treat constipation or diarrhea by modifying bowel motility or intestinal fluid balance.
Non-Pharmacological Management
- •Dietary modification: low-FODMAP for IBS; gluten-free diet for coeliac disease; low-fat for pancreatitis
- •Alcohol cessation: critical in alcoholic liver disease, pancreatitis, GERD
- •Weight loss: reduces GERD symptoms and improves NAFLD (5–10% weight loss reduces hepatic steatosis)
- •Elevate bed head; avoid late meals; avoid trigger foods in GERD
- •Regular meals; avoid NSAIDs and aspirin (gastric mucosal damage); no smoking
- •Endoscopic surveillance: Barrett's oesophagus, IBD colon cancer screening, cirrhosis for HCC
- •Vaccination: hepatitis A and B for unvaccinated at-risk patients
Treatment Goals
Monitoring Parameters
- ◆LFTs, bilirubin, albumin, INR: liver function — monthly in acute liver disease, every 3–6 months in chronic
- ◆FBC: anaemia (GI bleeding, malabsorption), leucopenia (azathioprine toxicity)
- ◆Faecal calprotectin: non-invasive IBD disease activity monitoring
- ◆Colonoscopy: IBD dysplasia surveillance every 1–5 years depending on duration and extent
- ◆H. pylori test of cure: UBT or stool antigen 4 weeks after eradication therapy
- ◆Hepatic elastography (FibroScan): assess fibrosis progression in chronic liver disease
- ◆Alpha-fetoprotein + ultrasound: HCC surveillance in cirrhosis every 6 months
Red Flags — When to Escalate
- ⚠Any of the characteristic symptoms of Irritable Bowel Syndrome (IBS) — even mild — in a high-risk individual
- ⚠Progressive worsening of early warning signs over weeks
- ⚠Laboratory abnormalities (e.g., blood sugar, inflammatory markers) without full symptoms
- ⚠Unexplained weight loss, night sweats, or fatigue persisting >2 weeks
- ⚠Strong family history of Irritable Bowel Syndrome (IBS) combined with new relevant symptoms
- ⚠Sudden worsening of Irritable Bowel Syndrome (IBS) symptoms despite established treatment
Escalation Criteria
- →Acute GI bleeding: upper GI endoscopy within 24h; resuscitation, IV PPI, haemostatic therapy
- →Acute severe UC (Truelove-Witts criteria) → hospitalisation, IV steroids; escalate to biologics/surgery if no response at 72h
- →Hepatic encephalopathy: lactulose, rifaximin; identify precipitant; assess for transplant listing
- →Acute-on-chronic liver failure: specialist gastroenterology/transplant centre referral
