[32] IBS is more prevalent in obese patients. [33]

Vitamin D treatment may be associated with less inflammatory bowel disease reoccurrence of symptoms (relapse). It is not clear if this treatment improves the person's quality of life or what the clinical response to vitamin D treatment. The ideal treatment regime and dose of vitamin D therapy has not been well enough studied. [90]
Its use in IBS is thought to be due to its calming ability for patients that have IBS symptoms that are worsened by anxiety. Clidinium bromide is a synthetic quaternary ammonium antimuscarinic, [5] a sub-class of a family of drugs known as anticholinergics. It treats IBS by decreasing gastrointestinal motility. Chlordiazepoxide can be habit ...
