The research results (see table) indicate that about 1 in 5 people have a slow transit (type 1 and 2 stools), while 1 in 12 has an accelerated transit (type 5 and 6 stools). SSC score (mean ± s.d.) ( Somatic Symptom Checklist) Distribution of risk factors in three groups classifiedĪccording to the colonic transit and subgroups classified according to the type of feces model century In 2007, the Mayo Clinic College of Medicine in Rochester, Minnesota, United States, reported a piece of epidemiological research conducted on a population of 4,196 people living in Olmsted County Minnesota, in which participants were asked to complete a questionnaire based on the Bristol stool scale. These four identified subtypes correlate with the consistency of the stool, which can be determined by the Bristol stool scale. ‡ In the absence of the use of antidiarrhoeal or laxative. † Bristol stool scale type 6–7 (fluffy pieces with ragged edges, soft or watery, no solid or completely liquid pieces) * Bristol stool scale type 1–2 (Separate hard lumps like nuts or sausage-shaped) Untyped IBS (IBS - U) – insufficient stool abnormalities to be IBS-C, D or M ‡ Mixed IBS (IBS - M) – lumpy or hard stools * ≥ 25% and loose (soft) or watery stools † ≥ 25% of bowel movements. IBS with diarrhea (IBS-D) – loose (soft) or watery stools † ≥ 25% and lumpy or hard stools * <25% of bowel movements. IBS with constipation (IBS-C) – lumpy or hard stools * ≥ 25% and loose (soft) or watery stools † <25% of bowel movements. More recently, according to the latest revision of the Rome III Criteria, six clinical manifestations of IBS can be identified: Subtypes prevalent presentation of stool in IBS according to the Rome III Criteria ġ. Historically, this scale of assessment of the faeces has been recommended by the consensus group of Kaiser Permanente Medical Care Program ( San Diego, California, US) for the collection of data on functional bowel disease (FBD).
Research conducted on irritable bowel syndrome in the 2000s, faecal incontinence and the gastrointestinal complications of HIV have used the Bristol scale as a diagnostic tool easy to use, even in research which lasted for 77 months.
IBS blood is present only if the disease is associated with haemorrhoids. It notices a strong correlation of the reported symptoms with stress indeed diarrhoeal discharges are associated with emotional phenomena. The presentation of symptoms is usually months or years and commonly patients consult different doctors, without great success, and doing various specialized investigations.
In some patients, chronic constipation is interspersed with brief episodes of diarrhoea while a minority of patients with IBS have only diarrhoea. People with irritable bowel syndrome (IBS) typically report that they suffer with abdominal cramps and constipation. See also: Irritable bowel syndrome and Rome process Uses Diagnosis of irritable bowel syndrome The Bristol stool scale is also very sensitive to changes in intestinal transit time caused by medications, such as antidiarrhoeal loperamide, senna, or anthraquinone with laxative effect. These and other data have allowed the scale to be validated. In the initial study, in the population examined in this scale, the type 1 and 2 stools were more prevalent in females, while the type 5 and 6 stools were more prevalent in males furthermore, 80% of subjects who reported rectal tenesmus (sensation of incomplete defecation) had type 7. Types 1 and 2 indicate constipation, with 3 and 4 being the ideal stools as they are easy to defecate while not containing excess liquid, 5 indicating lack of dietary fiber, and 6 and 7 indicate diarrhoea. Type 7: Watery, no solid pieces, entirely liquid (diarrhoea).Type 6: Fluffy pieces with ragged edges, a mushy stool (diarrhoea).Type 5: Soft blobs with clear cut edges.Type 4: Like a sausage or snake, smooth and soft (average stool).Type 3: Like a sausage but with cracks on its surface.Type 1: Separate hard lumps, like nuts (difficult to pass).2.1 Diagnosis of irritable bowel syndrome.
