Brief summary

Participants with constipation will take enzyme-rich malt extract for 4 weeks whilst completing a daily bowel habit diary before and during intervention.

Detailed description

This pilot study is an open label, pre-post interventional study to evaluate the use of ERME in the treatment of people with chronic constipation. This study involves eligible participants that have a diagnosis constipation according to the Knowles-Eccersley-Scott Score (KESS). Participants will receive intervention with a food supplement enzyme-rich malt extract (ERME) at a dose of 15ml twice daily with food. Before intervention commences, participants will complete baseline breath samples and a 7 day stool diary to assess stool frequency and consistency. Participants will then receive the ERME as instructed and continue to complete a bowel diary. Then at 4 weeks since starting the intervention, participants will provide another breath sample and complete another set of breath samples.

Interventions

DIETARY_SUPPLEMENTEnzyme-rich malt extract

Enzyme-rich malt extract (ERME) is a by-product of the malting process in which the cereal grain barley is dried. The ingredients are 100% barley malt extract. It smells and tastes sweet, with a runny jam-like texture. Malt extract has been used as a food stuff in baking and cookery for many years, but ERME is extracted by means which retains more active enzymes, such as amylase.
