hydrogen and Irritable Bowel Syndrome

hydrogen has been researched along with Irritable Bowel Syndrome in 71 studies

Hydrogen: The first chemical element in the periodic table with atomic symbol H, and atomic number 1. Protium (atomic weight 1) is by far the most common hydrogen isotope. Hydrogen also exists as the stable isotope DEUTERIUM (atomic weight 2) and the radioactive isotope TRITIUM (atomic weight 3). Hydrogen forms into a diatomic molecule at room temperature and appears as a highly flammable colorless and odorless gas.
dihydrogen : An elemental molecule consisting of two hydrogens joined by a single bond.

Irritable Bowel Syndrome: A disorder with chronic or recurrent colonic symptoms without a clearcut etiology. This condition is characterized by chronic or recurrent ABDOMINAL PAIN, bloating, MUCUS in FECES, and an erratic disturbance of DEFECATION.

Interventionparticles per million (Mean)
SYN-010 21 mg-22.623

Change in Abdominal Pain

"Change in severity of abdominal pain from baseline, as determined from weekly average visual analog scale (VAS) scores, relative to Rifaximin alone. VAS scores allows subject to choose 0 for no pain to 100 pain as bad as it could possibly be.~The Visual Analogue Scale (VAS) measures pain intensity. The VAS consists of a 10cm line, with two end points representing 0 no pain and 100 pain as bad as it could possibly be~The change between two time points is reported baseline and 4 weeks after cessation of treatment (at 6 weeks)" (NCT04557215)

Association of Urgency Symptom and Rectal Sensitivity Testing.

Association of urgency symptom and rectal sensitivity will be evaluated by the mean change in the balloon pressure (measured in mmHg) that leads to first urge sensation to defecate, evaluated based on the visual analogue scale defined in the primary outcome measure. (NCT03462966)
