Constipation is an unsatisfactory defecation distinguished by difficult stool passage, infrequent stools or both.
Difficult stool passage may include straining, feeling of difficulty in passing stool, incomplete evacuation, lumpy/hard stools, prolonged time to defecate, need for manual maneuver to pass stool, abdominal discomfort and feeling of anorectal blockade.
Chronic constipation is considered when symptoms of constipation have existed ≥3 months.
Symptoms of chronic constipation may be due to dysfunction of intestinal motility, visceral sensitivity, anorectal musculature or the enteric nervous system.
A 4-week treatment course of Bifidobacterium lactis NCC2818 in patients with chronic mild constipation does not appear to confer benefits for whole gut transit time and for other constipation-related outcomes, such as stool frequency and stool consistency, a study reports.

The novel local-acting ileal bile acid transporter inhibitor elobixibat helps relieve chronic constipation in the short term, with well tolerated safety profile in the long term — supporting the novel approach of increasing intracolonic bile acid concentration for treating chronic constipation, two phase III studies show.
Depression appears to be a stronger predictor of absenteeism than symptom severity in patients with chronic constipation, suggests a study, adding that depression may partly contribute to the indirect costs of chronic constipation.
Use of plecanatide in the treatment of chronic idiopathic constipation appears to induce notable improvements in bowel movement frequency, stool consistency, and straining and abdominal symptoms, with a low incidence of adverse events, according to the results of a phase III trial.
Absenteeism among patients with chronic constipation appear to have a stronger association with depression than symptom severity, according to a recent study, suggesting that a portion of the indirect costs of chronic constipation is attributable to depression.
Prucalopride elicits more high amplitude propagating contractions compared with PEG3350 in the 12-hour period following treatment among patients with chronic constipation, a randomised, cross-over, reader-blinded study has shown.
Cannabis use disorder appears to exert a beneficial effect on the risk of disorders of gut–brain interaction and inflammatory bowel disease in patients with schizophrenia but not in population controls, a study has found. This finding raises the possibility of new targets for treatment and prevention of digestive organ disorders in schizophrenia.
An individualized, food-based diet may be a potential treatment approach for patients with active Crohn’s disease, successfully replicating microbiome changes elicited by exclusive enteral nutrition and reducing gut inflammation, a recent study has shown.
Individuals with severe and frequent gastro-oesophageal reflux disease (GERD) are at increased risk of Barrett’s oesophagus (BE), especially in the absence of frequent proton pump inhibitor (PPI) use, a recent study has found. Family history of BE and early age of symptom onset are strong predictors of BE among people with GERD.
