IBS ( Irritable Bowel Syndrome) Statistics, Causes, Triggers, Diet and Treatment Infographic from Alphega-Pharmacy |
Irritable bowel syndrome (IBS) is a functional disorder of the gastrointestinal tract (GI).
IBS is considered to be a digestive disorder and is characterized by a collection of symptoms, ranging in severity from mild (about 40% of cases), moderate (about 35% of cases), to severe (about 25% of cases).
Prevalence
In the United States, IBS is the most common disorder diagnosed by gastroenterologists (physicians who specialize in digestive disorders and diseases) and is estimated to account for up to 12% of total visits to primary care providers.
IBS is estimated to affect up to 20% of the US and the UK adult population. However, it is also estimated that a large percentage (as many as 75%) of individuals suffering from IBS go undiagnosed.
IBS appears to be more common in women than in men, with about 35-40% of IBS cases reported by males and 60-60% reported by females.
IBS Subtypes
The recently revised Rome III Diagnostic Criteria defines four IBS subtypes based on the predominant stool pattern (volume, consistency and frequency) in the patient:
