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