Irritable bowel syndrome (IBS) is a common disorder that affects the large intestine. Signs and symptoms include cramping, abdominal pain. Irritable bowel syndrome (IBS) is a common, long-term condition of the digestive system. It can cause bouts of stomach cramps, bloating, diarrhoea and/or. WebMD offers coping tips for people with irritable bowel syndrome, or IBS.
(IBS) Irritable bowel syndrome
These symptoms are not caused by IBS and may indicate a more serious condition. A person should also see a doctor if their symptoms get progressively worse, stools are pale, bulky, very offensive smelling and difficult to flush away this may indicate a problem with absorbing fat , or if they are concerned about their symptoms. The exact cause of IBS is unknown, but experts think that several factors may be involved.
Triggers things that bring on an episode of IBS vary from person to person. The most common triggers include:. It is important that people try to identify their own triggers so that they can avoid or minimise IBS symptoms. The diagnosis of IBS can be challenging, because the symptoms are also seen in other digestive conditions. There is no one test that can show whether a person has IBS. A doctor will usually base the diagnosis on a person's symptoms and the elimination of other causes.
Sometimes investigations such as blood tests may be done to rule out other conditions. To help the process of diagnosis, experts have developed set of criteria to help determine if a person has IBS.
One example is the Rome criteria - this definition says that a person with IBS will have had abdominal pain and discomfort that lasts for at least 3 days a month in the last 3 months, plus 2 or more of the following:. IBS can usually be managed with diet and lifestyle modifications, including stress management, getting enough sleep and exercise. It can also be helpful to keep a diary of events surrounding each episode to help identify things that may trigger IBS symptoms or make them worse, such as trigger foods.
Irritable bowel syndrome treatment focusses on diet and lifestyle changes, as well as medicines. Irritable bowel syndrome IBS is a disorder in which the normal rhythmic movement of your gut bowe.

This is thought to be due to the large number of serotonin receptors in the gut. Certain atypical antipsychotic medications, such as clozapine and olanzapine , may also provide relief due to serotonergic properties these agents possess, acting on the same receptors as other medications in this specific category. Any nausea present may also respond to 5HT3 antagonists owing to their antiemetic properties. The bowels are highly dependent on serotonin for neural communication.
Further research is required. Mast cells and the compound that they secrete are central to the pathophysiology and implicated in the treatment of IBS;  some of the secreted mast cell mediators and associated receptors which have been implicated in symptoms of IBS or specific subtypes include: For people who do not adequately respond to dietary fiber, osmotic laxatives such as polyethylene glycol , sorbitol , and lactulose can help avoid " cathartic colon " which has been associated with stimulant laxatives.
The use of antispasmodic drugs e. A meta-analysis by the Cochrane Collaboration concludes if seven people are treated with antispasmodics, one of them will benefit. Musculotropics, such as mebeverine , act directly at the smooth muscle of the gastrointestinal tract, relieving spasm without affecting normal gut motility.
Proton pump inhibitors PPIs used to suppress stomach acid production may cause bacterial overgrowth leading to IBS symptoms. Discontinuation of PPIs in selected individuals has been recommended as it may lead to an improvement or resolution of IBS symptoms.
There is good evidence that low doses of tricyclic antidepressants can be effective for IBS. However, the evidence is less robust as to the effectiveness of other antidepressant classes such as SSRIs.
Antidepressants are not effective for IBS in people with depression, possible because lower doses of antidepressants than the doses used to treat depression are required for relief of IBS. Due to severe adverse effects, namely ischemic colitis and severe constipation, they are not available or recommended.
Magnesium aluminum silicates and alverine citrate drugs can be effective for IBS. Evidence is conflicting about the benefit of antidepressants in IBS. Some meta-analyses have found a benefit, while others have not.
Rifaximin may be useful as a treatment for IBS symptoms, including abdominal bloating and flatulence, although relief of abdominal distension is delayed. In individuals with IBS and low levels of vitamin D supplementation is recommended.
Some evidence suggests that vitamin D supplementation may improve symptoms of IBS, but further research is needed before it can be recommended as a specific treatment for IBS.
Domperidone , a dopamine receptor blocker and a parasympathomimetic, has been shown to reduce bloating and abdominal pain as a result of an accelerated colon transit time and reduced fecal load, that is, a relief from 'hidden constipation'; defecation was similarly improved. The use of opioids is controversial due to the potential risk of tolerance , physical dependence , and addiction , but can be the only relief for some diarrhea-predominant cases when other treatment has been ineffective.
Statistically significant reduction in IBS symptoms occurs following antibiotic therapy for small intestinal bacterial overgrowth. There is low quality evidence from studies with poor methodological quality that psychological therapies can be effective in the treatment of IBS; however there are no significant adverse effects from psychological therapies for IBS.
Reducing stress may reduce the frequency and severity of IBS symptoms. Techniques that may be helpful include:. Probiotics can be beneficial in the treatment of IBS; taking 10 billion to billion beneficial bacteria per day is recommended for beneficial results.
However, further research is needed on individual strains of beneficial bacteria for more refined recommendations. A number of probiotics have been found to be effective, including Lactobacillus plantarum ,  and Bifidobacteria infantis ;  but one review found only Bifidobacteria infantis showed efficacy.
Certain probiotics have different effects on certain symptoms of IBS. For example, Bifidobacterium breve , B.
Most clinical studies show probiotics do not improve straining, sense of incomplete evacuation, stool consistency, fecal urgency, or stool frequency, although a few clinical studies did find some benefit of probiotic therapy.
The evidence is conflicting for whether probiotics improve overall quality of life scores. Probiotics may exert their beneficial effects on IBS symptoms via preserving the gut microbiota, normalisation of cytokine blood levels, improving the intestinal transit time, decreasing small intestine permeability, and by treating small intestinal bacterial overgrowth of fermenting bacteria.
Peppermint oil appears useful. Occasionally, nausea and perianal burning occur as side effects. Only limited evidence exists for the effectiveness of other herbal remedies for IBS. As with all herbs, it is wise to be aware of possible drug interactions and adverse effects.
Yoga may be effective for some people with IBS, especially poses which exercise the lower abdomen. A meta-analysis found no benefits of acupuncture relative to placebo for IBS symptom severity or IBS-related quality of life.
The prevalence of IBS varies by country and by age range examined. The bar graph at right shows the percentage of the population reporting symptoms of IBS in studies from various geographic regions see table below for references. The following table contains a list of studies performed in different countries that measured the prevalence of IBS and IBS-like symptoms:. Women are around two to three times more likely to be diagnosed with IBS and four to five times more likely to seek specialty care for it than men.
People diagnosed with IBS are usually younger than 45 years old. Because women are at higher risk of sexual abuse than men, sex-related risk of abuse may contribute to the higher rate of IBS in women. The concept of an "irritable bowel" appeared in the Rocky Mountain Medical Journal in The term was used to categorize people who developed symptoms of diarrhea, abdominal pain, and constipation, but where no well-recognized infective cause could be found.
Early theories suggested the irritable bowel was caused by a psychosomatic or mental disorder. Other names for the condition used in the past included irritable colon, spastic colon, nervous colon, colitis, mucous colitis, and spastic bowel.
The terminologies that refer to the colon are inaccurate and discouraged, since the disorder is not limited to this section of the digestive tract. Similarly, the term "colitis" is not accurate as inflammation is not present. People with IBS had higher costs for physician visits, outpatients visits, and prescription drugs. The study suggested the costs associated with IBS were comparable to those found for people with asthma. Individuals with IBS have been found to have decreased diversity and numbers of bacteroidetes microbiota.
Preliminary research into the effectiveness of fecal microbiota transplant in the treatment of IBS has been very favourable with a 'cure' rate of between 36 percent and 60 percent with remission of core IBS symptoms persisting at 9 and 19 months follow up. There is increasing evidence for the effectiveness of mesalazine 5-aminosalicylic acid in the treatment of IBS. It has also been observed that mesalazine therapy helps to normalise the gut flora which is often abnormal in people who have IBS.
The therapeutic benefits of mesalazine may be the result of improvements to the epithelial barrier function. Differences in visceral sensitivity and intestinal physiology have been noted in IBS. A questionnaire in designed to learn people's perceptions about IBS, their preferences on the type of information they need, and educational media and expectations from health care providers revealed misperceptions about IBS developing into other conditions, including colitis , malnutrition , and cancer.

Lifestyle changes can help control symptoms of IBS. Many people with IBS find their symptoms can be greatly improved by staying away from foods that contain a family of carbohydrates called FODMAPs fermentable, oligosaccharides, disaccharides, monosaccharides and polyols. Some dietary ingredients can cause the bowel to stretch and expand.
This happens because they attract fluid and quickly produce gas when they come in contact with or are fermented by bacteria in your bowel. The most common dietary ingredients that do this are called fermentable, poorly absorbed, short-chain carbohydrates. These are sugars that your body can't digest but which become a quick meal for bacteria. If this seems too complex — just remember that 'saccharide' is a different word for sugar.
Polyols are sugar alcohols — meaning sugar molecules that have an alcohol side-chain attached. You might already know some of these sugars or have seen them in ingredients lists on food packaging.
