Irritable Bowel Syndrome

Irritable Bowel Syndrome

IBS is characterised by a combination of symptoms and signs, such as abdominal pain, constipation (IBS-C), diarrhoea (IBS-D) — or alternating between both (IBS-A) — a noted change in both the frequency and consistency of stools, rectal mucus due to hypersecretion of colonic mucus, dyspeptic symptoms including anorexia, flatulence, gastro-oesophageal reflux (GOR) and nausea, and an emotional component where anxiety and/or depression are often noted. Abdominal pain is often relieved following defecation.

IBS and Diet
Most dietary studies relating to IBS have been observational, and only small proportions are randomised controlled trials. Nevertheless, they are useful in suggesting treatment options.

Gas, diet and IBS
The daily production of gas in the human gastro-intestinal tract (GIT) is 500-1500ml, and the volume found at any given time is 200ml.  Five major gases are responsible for the development of flatus, i.e. carbon dioxide, hydrogen, hydrogen sulphide, methane, and oxygen. Oxygen found in the GIT is the result of swallowed air during the course of eating and drinking (aerophagia), or it may be due to hyperventilation in cases of anxiety. Greater amounts would be expected in subjects who eat too quickly, chew gum, or smoke, as not all is absorbed or expelled following belching….for more information phone John for an appointment in Sydney on: 9262 1011
