What Will I Have to Do?

If you are eligible to participate, you will need to visit the study clinic 3 times over approximately 12 weeks to have your health checked. You may have the option for two of these visits to be by a nurse in your home if you cannot access the clinic. During these visits you will be asked questions about your health and medical history, you may have blood drawn and stool collected for testing, and you may have other health testing performed. Your medications will be delivered to your home and you will be told how to take them. Between visits to the clinic you will need to download an app onto your smart phone where you will complete a stool diary. You will also be required to complete regular questionnaires about how you are feeling.

All items needed to conduct study tests will be provided. You are not responsible for any study-related expenses.

Is there any benefit to this study?

You may experience relief from symptoms related to your IBS-D. Additionally, you will be compensated for your time and participation  and receive a personalised gut microbiome report. 

Do I Need Medical Records?

No. You don’t need to provide a copy of your medical records from your doctor, however you will be asked to answer some questions related to your past and current health status to ensure you qualify.

How Long is the Study?

This study requires you to participate for 12 weeks.

Will I receive any information about my gut health?
