Clinical Trial Summary

Functional constipation (FC) is a common condition associated with aging, lower socioeconomic status, low physical activity and also with reduced fibre, water and magnesium intakes. Different studies have reported a positive association between the intake of hyper-mineral water containing a high content of bicarbonate, calcium, or magnesium, and the improve of the gastrointestinal transit. There is evidence that magnesium and sulphate, both individually, have a laxative action. However, the impact of other minerals is scarce. It has been described different mechanisms explaining how gut microbiota influence the gastrointestinal transit. Specifically, in FC patients, it is important to understand the particularities of their gut microbiota and understand whether the intake of hyper-mineral water, a natural source of minerals, can modify positively the gut microbiota. The aim of the present randomized placebo-controlled pilot trial is to evaluate, for the first time, the effect of the carbonated mineral water consumption in the gastrointestinal transit and in the gut microbiota of subjects with FC.
