Overview
Irritable Bowel Syndrome (IBS) is a common, chronic gastrointestinal disorder characterized by abdominal pain or discomfort and altered bowel habits without any identifiable structural or biochemical cause.
Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder that affects the large intestine. It is characterized by a group of symptoms that occur together, including abdominal pain, cramping, bloating, gas, and changes in bowel habits (diarrhea, constipation, or both). Unlike inflammatory bowel diseases (IBD) such as Crohn's disease or ulcerative colitis, IBS does not cause inflammation or changes in bowel tissue, nor does it increase the risk of colorectal cancer. However, it can significantly impact quality of life.
The exact cause of IBS is not fully understood, but it is believed to involve a combination of factors. These can include abnormalities in the gut-brain axis (the communication pathway between the brain and the gut), changes in gut microbiota, increased sensitivity of the intestines, and altered gut motility. Psychological factors such as stress, anxiety, and depression are also known to influence IBS symptoms. Diagnosis typically involves ruling out other conditions and identifying a pattern of symptoms consistent with established diagnostic criteria, such as the Rome IV criteria.

International evidence & guidelines
How global health authorities view Irritable Bowel Syndrome.
The National Institute for Health and Care Excellence (NICE) in the UK recommends dietary and lifestyle advice, including regular meals, avoiding trigger foods, and considering a low-FODMAP diet under specialist supervision. They also suggest psychological therapies like CBT and hypnotherapy. The American College of Gastroenterology (ACG) guidelines support the use of soluble fiber (like psyllium) and peppermint oil for global IBS symptoms. They also acknowledge the role of certain probiotic strains. The World Health Organization (WHO) recognizes the importance of dietary management and stress reduction in functional gastrointestinal disorders. Many international bodies emphasize a holistic approach, combining conventional medical treatments with lifestyle and dietary modifications.

Abdominal pain related disorders of gut-brain interaction (AP-DGBIs) such as irritable bowel syndrome (IBS) and functional abdominal pain-not otherwise specified (FAP) are common conditions in children, significantly impacting quality of life. This treatment guideline for IBS and FAP in children of 4-18 years is a collaborative effort of the European and North American Societies for Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN and NASPGHAN). We aim to comprehensively review the current evidence on treatment options and offer evidence-based recommendations with utility across all treatment settings worldwide, as well as to provide methodological directions for future research. The guideline development followed the "Grading of Recommendations Assessment, Development and Evaluation" (GRADE) approach, which is in accordance with the GRADE handbook and supported by the World Health Organization.

The aim of this position statement is to provide health professionals with an updated and evidence-based guideline for the pharmacologic management of irritable bowel syndrome (IBS) in Mexico. A literature review was conducted that included relevant guidelines and studies, up to the date of its publication. The mechanism of action, specific indications in IBS, safety profile, and availability of each therapeutic class were evaluated. The recommendations were developed by 14 experts, considering the clinical reality of IBS patients in Mexico. Specific recommendations were issued for each class. Antispasmodics (alone or combined) are used as first-line therapy for pain management, whereas antidiarrheals, such as loperamide, are used for reducing diarrhea in diarrhea-predominant IBS (IBS-D) and laxatives are used for constipation in constipation-predominant IBS (IBS-C). 5-HT4 agonists (prucalopride and mosapride) are recommended in IBS-C and 5-HT3 antagonists (ondansetron) are recommend

Abdominal distension is an objective visible sign of increased abdominal girth. Bloating is a feeling of abdominal fullness and discomfort. Bloating may be associated or not with abdominal distension. Bloating and abdominal distension are among the most commonly reported gastrointestinal symptoms and may be associated with both organic and functional disorders. Nevertheless, specific consensus and recommendations on diagnosis, underlying mechanisms, assessment and management of functional bloating and abdominal distension are still lacking. The aim of this European consensus, then, is to provide expert opinions and recommendations on the epidemiology, diagnosis, pathophysiology and treatment of functional bloating and abdominal distension. A multidisciplinary team of experts in the field, including European specialists and national societies, participated in the development of this consensus. Relevant questions were formulated and addressed through a literature review and statements w

Working alongside conventional care
Conventional medical care for IBS often involves symptom management with medications such as antispasmodics, laxatives, anti-diarrheals, and sometimes antidepressants. Specific medications for IBS-C (e.g., lubiprostone, linaclotide) and IBS-D (e.g., rifaximin, eluxadoline) are also available. A healthcare provider can help determine the most appropriate treatment plan based on individual symptoms
