Active clinical trials for "Irritable Bowel Syndrome"

The purpose of this study is to compare the safety and effectiveness of different doses of an investigational medication in women with severe diarrhea-predominant Irritable Bowel Syndrome (IBS) who have failed conventional therapy.

A remote study to find out if a mobile phone application (HealthMode Stool) can serve as a useful tool to track and characterize daily bowel movements. The application provides participants with a single place to record their bowel movements either as a part of their general health self-monitoring, or because they may be dealing with a bowel movement condition. The minimal study duration is 1 month, and participants can continue using the application up to 2 years.

A high fermented, oligio-, di-, monosaccharide, and polyols (FODMAP) diet has been shown to exacerbate the symptoms of irritable bowel syndrome (IBS). Previous literature has shown significant improvement in IBS symptoms after adherence to a low FODMAP diet (LFD); hence, LFD is a viable treatment method for IBS and IBS-like symptoms. However, adherence to the LFD has proven to be difficult with participants stating that information provided by medical practitioners is generalized and nonspecific requiring them to search for supplementary information to fit their individual needs. Notably, studies that have used a combination of online and in-person methods for treatment have shown improved adherence to the LFD. The purpose of this study is to determine whether a novel machine learning dietary mobile application (ML-App) will improve adherence to the LFD compared to a standard online dietary intervention in populations with IBS or IBS-like symptoms over a 4 week period.

The purpose of the trial is to develop a treatment protocol to be used in trials studying internet-delivered CBT for children with functional gastrointestinal disorders (FGID). The study size is not based on power calculations but the estimated sample necessary to develop a treatment protocol. This study will include 20-30 children with FGID and their parents who will be treated individually (face-to-face). The treatment consists of 10 weekly sessions of exposure-based CBT. The study uses a pre- post-design with no control group.

Patients with a diagnosis of irritable bowel syndrome (IBS) are recruited by self-referral. They are randomized to two 10 weeks of internet-delivered cognitive behavioral programs. Both programs include mindfulness training, education about how excessive avoidant and control behaviors maintain IBS symptoms, and changing of these behaviors to live a richer life. One of the programs also includes instructions on how to perform systematic exposure. The hypothesis of the study is while both groups will show improvement in terms of IBS symptom severity and quality of life, the addition of systematic exposure will lead to more improvement in symptoms.

Constipation is a common digestive disorder. After excluding dietary factors, drugs and other secondary causes, at least three broad pathophysiologic subtypes are recognized- dyssynergic defecation, constipation-predominant irritable bowel syndrome (IBS-C) and slow transit constipation (STC), all predominantly affect women and elderly. Many patients also demonstrate abnormal rectal perception with both rectal hyposensitivity and hypersensitivity being common. Recent surveys show that most constipated patients are dissatisfied with current therapy. Also, constipated patients showed significant psychological dysfunction and impaired quality of life. OBJECTIVE: To investigate a novel biofeedback technique of improving rectal hypersensitivity. METHODS: A large compliant balloon attached to a barostat was placed in the rectum in 8 patients with rectal hypersensitivity (urgency/pain threshold <30 mm Hg). Sensory deconditioning was performed by incremental balloon distensions (1-2 mmHg) until normal thresholds were reached.

The purposes of this study are to estimate the burden of disease due to chronic gastrointestinal illness in PG veterans, to evaluate whether Small Bowel Bacterial Overgrowth (SBBO) is associated with chronic diarrhea in PG veterans, and to determine whether eradication of SBBO reduces symptoms of chronic diarrhea, abdominal pain and bloating in PG veterans.

This is a three-period crossover study to compare GW876008 and placebo to see if GW876008 will normalise blood flow responses after different emotional stimuli.

This study will look at colonic mucosal blood flow in subjects who have taken alosetron vs placebo and healthy volunteers vs diarrhea-predominant Irritable Bowel Syndrome (d-IBS) patients.

This randomized study evaluates the usefulness of the I31 probiotic formula, alone or in combination with alverine/simethicone, against placebo, in the treatment of diarrhea-predominant or mixed irritable bowel syndrome
