Brief Summary
Constipation is a prevalent gastrointestinal condition. Beyond simple lifestyle measures (e.g. increasing fibre intake, hydration, levels of exercise), medical therapies are available for management. However, a sizeable number of sufferers are dissatisfied with drug treatments (either over-the-counter or prescribed), meaning there is an unmet need for alternative therapeutic strategies. Pre, pro- and synbiotics have emerged as one alternative treatment, and a growing body of evidence now supports their use in a proportion of individuals with mild constipation. However, it is currently not possible to predict which individuals may benefit. A better understanding of an individuals' symptoms and underlying pathophysiology may allow for more targeted treatment. The multistrain live bacterial food product (probiotic) being tested contains billions of live and active bacteria that has been shown to improve symptoms in the irritable bowel syndrome (IBS: which is 'constipation-predominant' in many). Notably, improvements ('completely resolved' or 'some positive difference') in bowel habit satisfaction, abdominal pain, bloating and urgency, as well as on quality of life have been shown after 4 or more weeks of this probiotc. This study aims to have 20 participants with self-reported constipation to assess improvements in constipation symptoms, quality of life and measures of gut function.
