Irritable bowel syndrome
- is a common, uncomfortable, distressing and sometimes disabling condition
- is not the same as inflammatory bowel disease
- leads to abdominal pain and cramping, changes in bowel movements, and other symptoms
- does not
- permanently harm the intestines
- lead to serious disease, such as cancer
- is a diagnosis of exclusion because no specific laboratory or other tests are available for differential diagnosis.
Other terminology includes the following.
- Colitis, alternative or obsolete term for irritable bowel syndrome.
- Idiopathic, term used for any disease that is of uncertain or unknown origin.
- Inflammatory bowel disease (IBD)
- is an idiopathic disease, involving an immune reaction of the body to its own intestinal tract (likely resulting from a combination of genetic and environmental factors)
- is often confused with irritable bowel syndrome (IBS)
- but the two are different conditions with different causes
- although they have some symptoms in common, such as
- abdominal discomfort
- bowel irregularity
- occurs as two major types, which have inflammation as the principal pathology and comprises
- ulcerative colitis (CDHO Advisory)
- Crohn’s disease (CDHO Advisory)
- Irritable colon, alternative or obsolete term for irritable bowel syndrome.
- Mucous colitis, alternative or obsolete term for irritable bowel syndrome.
- Nervous colon, alternative or obsolete term for irritable bowel syndrome.
- Somatoform disorder, a condition in which the physical pain and symptoms
- are related to psychological factors
- cannot be traced to a specific physical cause
- are real to the person.
- Serotonin, a neurotransmitter that helps relay signals from one area of the brain to another and that

Occurrence
Irritable bowel syndrome
- is the most common gastrointestinal diagnosis worldwide and the most common disorder presented to gastrointestinal specialists
- can occur at any age, but
- often begins in adolescence or early adulthood
- begins before age 35 in about 50 percent of persons affected by it
- affects 13–20 percent of Canadians at any given time, with lifetime risk of 30 percent
- occurs more often in women than in men
- occurs in the colon
- where it is associated with abnormal motility of the colon, which may vary from sudden strong contractions to cessation of motility, resulting in
- constipation caused by decreased motility, which increases absorption of fluids from the colon
- diarrhea caused by increased motility, which decreases absorption of fluids from the colon
- but is not limited to the colon.
- where it is associated with abnormal motility of the colon, which may vary from sudden strong contractions to cessation of motility, resulting in
Cause
Irritable bowel syndrome
has a cause or causes that are not understood; theories include
- abnormalities in gastrointestinal secretions and/or peristalsis.
- abnormally high levels of serotonin in the intestinal tract that heighten the sensitivity of its pain receptors
- amount of physical exercise
- antibiotic use
- bile acid malabsorption
- chronic alcohol abuse (CDHO Advisory)
- involvement of the immune system
- neurological links by which stress signals from the brain
- increase the sensitivity of the intestines
- cause the intestines to contract excessively
- physical, emotional and psychological stress
- post-infection origins, such as
- bacterial infection of the intestine
- acute enteritis, such as traveller’s diarrhea, as precursor to persistent altered bowel function despite elimination of the affecting organism
- some association with celiac disease (CDHO Advisory), but not with inflammatory bowel diseases
- special sensitivity and reactivity to food.
Risk factors
Irritable bowel syndrome
is associated with stress, conflict, or emotional upsets, which may
- especially take the form of feelings of mental or emotional tension, or of being troubled, angry, or overwhelmed
- provoke the colon through connections with the autonomic nervous system that, in many persons without irritable bowel syndrome, responds to stressful times with abdominal discomfort
- affect the immune system.
Signs and symptoms
Irritable bowel syndrome
- is a debilitating condition the symptoms of which
- vary from person to person
- range from mild to severe
- are most commonly mild
- may be episodic
- may be persistent
- may worsen over time
- are most commonly
- abdominal pain
- bloating
- constipation
- cramping
- diarrhea
- may also
- be accompanied by loss of appetite
- be triggered by stress
- be triggered by eating
- alternate as episodes of constipation and diarrhea
- be associated with changes the pattern or frequency of bowel movements
- be accompanied by mucus in the stool
- include urgency for bowel movements
- occur rarely during the night
- include
- fatigue
- headache
- nausea
- be relieved after a bowel movement
- is exacerbated in its symptoms by
- large meals
- bloating from gas in the colon
- medications
- food such as
- barley
- chocolate
- milk products
- rye
- wheat
- drinks with
- alcohol
- caffeine, such as coffee, tea, or colas
- menstruation in some women

- presents symptoms that for most persons can be controlled with diet, stress management, and medications
- may be disabling for some persons to the extent that they cannot work, travel or attend social events
- is not associated with symptoms and signs
- such as
- bleeding
- fever
- weight loss
- or persistent severe pain
- that may indicate conditions such as inflammatory bowel disease.
- such as
Medical investigation
Of irritable bowel syndrome
- lacks a definitive diagnostic test, so diagnosis is one of exclusion of other causes of the symptomatology. The Rome IV criteria (May 2016) for the diagnosis of IBS require that patients/clients have had recurrent abdominal pain on average at least 1 day per week during the previous 3 months that is associated with 2 or more of the following:
- related to defecation (may be increased or unchanged by defecation)
- change in stool frequency
- change in stool form or appearance
- supporting signs/symptoms may be present, such as
- altered stool frequency
- altered stool form
- altered stool passage (staining and/or urgency)
- mucus in the stool
- abdominal bloating or subjective distention
- may involve
- tests for
- anemia
- bowel infection
- celiac disease
- lactase deficiency
- thyroid function
- parathyroid function (i.e., serum calcium to screen for hyperparathyroidism)
- inflammation
- colonoscopy
- tests for
- may lead to confusion in diagnosis with gynaecological and other pelvic conditions.
Treatment
Of irritable bowel syndrome
- aims to relieve symptoms
- includes lifestyle changes to reduce anxiety and help relieve bowel symptoms, such as
- regular exercise
- improved sleep habits
- individualized dietary changes, including
- avoiding foods and drinks that stimulate the intestines, such as caffeine, tea, or colas
- avoiding large meals
- increasing fibre in the diet, which may relieve constipation but exacerbate bloating
- legume avoidance, which may decrease abdominal bloating
- probiotics
- psychological interventions, psychotherapy, cognitive-behavioural therapy, and hypnotherapy.
Prevention
Irritable bowel syndrome has no demonstrated means of prevention, though its symptoms can often be managed.
Prognosis
Irritable bowel syndrome
- may be
- a lifelong condition accompanied by disabling symptoms
- or it may be managed, improved or relieved with treatment
- does not
- cause permanent damage to the intestines
- lead to other serious medical diseases, such as cancer.
Social considerations
Of irritable bowel syndrome arise for persons who
- because of it, cannot work, travel or attend social events
- are especially affected by its psychosocial accompaniments.

Comorbidity, complications and associated conditions
Comorbid conditions are those which co-exist with irritable bowel syndrome but which are not believed to be caused by it. Complications and associated conditions are those that may have some link with it. Distinguishing among comorbid conditions, complications and associated conditions may be difficult in clinical practice.
For irritable bowel syndrome
- excess comorbidities are found for infections and some well-defined disorders
- relations of comorbidities, complications and associated conditions are incompletely understood in for the following reasons
- comorbidity, complications and associated conditions
- occur with other functional gastrointestinal disorders and may be caused by shared factors such as intestinal hypersensitivity
- may be influenced by but are not explained by psychiatric illnesses, which co-occur frequently, especially
- major depression (CDHO Advisory)
- anxiety (CDHO Advisory)
- somatoform disorders
- the non-gastrointestinal, non-psychiatric disorders with the best-documented associations with irritable bowel syndrome comprise
- chronic fatigue syndrome
- chronic pelvic pain
- fibromyalgia
- temporomandibular joint disorder
- general amplification of symptom reporting is observed
- excess comorbidity is observed to be due to hyper-vigilance
- for noticing somatic sensations
- expressed as a lower threshold for consulting a physician
- one explanation, among others, holds that the irritable bowel diagnosis is applied to a heterogeneous group of persons
- of whom some experience a predominantly psychological etiology
- of whom some experience a predominantly biological etiology
- for some for whom multiple comorbid disorders may be a marker for psychological influences.
- comorbidity, complications and associated conditions
Oral health considerations
- The gastrointestinal system is sensitive to adrenaline, also called epinephrine, the ‘fight or flight’ hormone, released from the adrenal glands in a threatening situation, which dental procedures are to some patients/clients.
- Increasing the comfort level of dental hygiene patients/clients with irritable bowel syndrome is an important preventive measure.
- Because the causal factors of irritable bowel syndrome are not adequately understood, professional caution is required in the interpretation of information on the Internet such as
- unapproved, untested and unofficial treatments
- sources linking it with the controversies of oral healthcare, such as mercury-based fillings, fluoride and fluoridation.
