Abstract

Irritable bowel syndrome (IBS) is a common disorder of gut-brain interaction which can have a considerable impact on quality of life. Following diagnosis, timely and evidence-based management is vital to the care of patients with IBS, aiming to improve outcomes, and enhance patient satisfaction. Good communication is paramount, and clinicians should provide a clear explanation about the disorder, with a focus on exploring the patient’s own beliefs about IBS, and a discussion of any concerns they may have. It should be emphasised that symptoms are often chronic, and that treatment, while aiming to improve symptoms, may not relieve them completely. Initial management should include simple lifestyle and dietary advice, discussion of the possible benefit of some probiotics, and, if this is unsuccessful, patients can be referred to a dietician for consideration of a low FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides and polyols) diet. Antispasmodics and peppermint oil can be used first-line for the treatment of abdominal pain. If patients fail to respond, central neuromodulators can be used second-line; tricyclic antidepressants should be preferred. Loperamide and laxatives can be used first-line for treating diarrhoea and constipation, respectively. Patients with constipation who fail to respond to laxatives should be offered a trial of linaclotide. For patients with diarrhoea, the 5-hydroxytryptamine-3 receptor agonists alosetron and ramosetron appear to be the most effective second-line drugs. Where these are unavailable, ondansetron is a reasonable alternative. If medical treatment is unsuccessful, patients should be referred for psychological therapy, where available, if they are amenable to this. Cognitive behavioural therapy and gut-directed hypnotherapy are the psychological therapies with the largest evidence base.
