About

This study intends to evaluate the microbiome of chronically constipated patients as compared to those with a non-constipated gastrointestinal system.

Full description

Biogeographically accurate microbiome sampling using the HyGIeaCare platform and an evolutionary biology informed learning platform will allow an improved discovery of bacterially derived novel molecular entities with therapeutic potential for chronic constipation. This approach intends to enhance our ability to understand the gut microbiome and use it towards developing therapeutic solutions, in comparison to traditional collection methods and taxonomic-based data analysis approaches.

Enrollment: 30 patients

Sex: All

Ages: 18 to 80 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

3. Adequate capacity to consent to study
4. Patient does not have any known health issues, except for chronic constipation for the "chronic constipation" population.
5. Patient has not taken antibiotics within the last three (3) months.
6. For chronically constipated patients - >3 months of symptomatic constipation with first onset of constipation more than 6 months ago.

For chronically constipated patients - Diagnosis of functional constipation by Modified Rome IV Diagnostic Criteria.

Exclusion criteria

1. Patient has functional bowel disorders characterized by alternating bowel habits (diarrhea/constipation).

2. Patient has any other condition that, in the opinion of the investigator, may adversely affect the compliance or safety of the patient or would limit the patient's ability to complete the study.
