This process (peristalsis) is usually painless and we do not realise that it is happening unless there is abnormal squeeze within the bowel or, for some reason, the intestine becomes more sensitive. Overall, there seems to be some interaction between the nervous system in the gut and brain, emotional state and the immune system of the gut.ĭuring digestion, the intestine squeezes its contents along our insides towards the anus. Others notice IBS developing after they have had a bout of food poisoning or gastroenteritis. In some people, eating irregularly or eating an abnormal diet may be responsible. Some people believe that stress makes their symptoms worse. We do not think that IBS has a single cause and there seem to be many reasons why patients develop the condition. Therefore, it is also a very frequent reason for GPs to refer patients to a hospital specialist. IBS is one of the commonest reasons for patients to visit a GP. Women are slightly more affected than men and the usual age for patients to seek advice is between 20 and 40 years of age. IBS is just about the most common disorder of the digestive system and up to one-third of the population experience symptoms from time to time. There are often other syndromes where bodily pain is present, such as fibromyalgia, chronic back pain, non-specific urethritis. Many patients notice that they lack energy and sleep poorly. Other symptoms vary from individual to individual but include a sensation of bloating, visible abdominal swelling, a sense of incomplete emptying of the bowels and passage of mucus (slime) from the back passage. Some patients may notice they need to get to a toilet in a hurry. The bowel habit is often irregular – there can be diarrhoea or constipation and sometimes it swings between these two extremes. Altered bowel habit – constipation/diarrhoea.Many patients with IBS get crampy abdominal discomfort or pain, which comes and goes, and which fluctuates with bowel function (typically easing after a bowel action).
The most important symptoms in IBS are abdominal pain and abnormal bowel habit. The Irritable Bowel Syndrome (IBS) consists of a number of symptoms. The term ‘syndrome’ seems quite grand but it is just the word that doctors use to describe a collection of symptoms.
