Abstract: Irritable bowel syndrome (IBS) is a complex functional gastrointestinal disorder that is exceedingly common in clinical practice. IBS with predominant constipation (IBS-C) is a subtype of IBS that accounts for more than a third of the IBS diagnosed. Diagnosis of IBS requires a careful personalized approach, a comprehensive clinical history, limited but relevant investigations, and continued follow-up. Major IBS societies and guidelines recommend offering a positive diagnosis of IBS based on presenting symptomatology. Abdominal pain that may or may not be relieved by defecation is the cardinal symptom of IBS; distension and bloating are other common symptoms. Careful attention should be paid to alarm symptoms before a diagnosis of IBS is made. Pharmacotherapy with linaclotide is recommended for moderate–severe IBS-C, based on high-quality evidence from randomized controlled trials. Diarrhea is the major side effect of linaclotide, and limited cost-effectiveness data currently exist.
