Stool samples will be collected before and during the HyGIeaCare procedure and the samples will be sent for microbiome evaluation.

Patients will have the HyGIeaCare procedure as originally prescribed by their physician. Before and during the procedure stool samples will be collected and sent to a lab for microbiome evaluation.

It is anticipated that stool samples collected from the HyGIeaCare prep will provide more microbiological and biochemical information on the gut interior than using traditional stool samples.
