Alterations in motility (leading to constipation or diarrhoea).These occurrences can result in changes within the digestive system as well as altered signalling between the gut and the brain. Researchers have identified particular alterations in the gut which include: Long term dietary patterns (a low fibre diet).While the cause of IBS isn’t exactly known and likely varies from person to person, there are several risk factors associated with the development of IBS. While these risk factors do not guarantee that someone will develop the symptoms of IBS or an increase in stomach noises, it does increase the chances. Īlthough the noises that the stomach can generate are not within the criteria for an IBS diagnosis, they are often also present with other IBS symptoms. For example, there should be no indication of conditions such as inflammatory bowel disease ( IBD) or coeliac disease. There also needs to be the absence of any other diagnosed digestive disease. This indicates that to be diagnosed with IBS, an individual needs to experience abdominal pain changes in bowel patterns.
This diagnosis of IBS is based on meeting the symptoms outlined in the ROME criteria. However, cases in the general population are towards the higher end of this scale in westernised cultures. IBS is also nearly twice as common in women as in men. IBS is one of the most diagnosed digestive conditions, with a global prevalence of 10-20%.
