Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are individuals diagnosed with type 1 diabetes who regularly attend the diabetes outpatient clinic.
✕Probably not a fit
Patients who are pregnant, breastfeeding, or have other chronic or acute diseases may not benefit from this study.

What this trial studies
This observational study aims to investigate the determinants of postprandial glucose response (PGR) in individuals with type 1 diabetes. Participants will record their dietary habits over a week, complete food frequency questionnaires, and provide stool samples to analyze gut microbiota composition. Blood samples will also be collected to evaluate various metabolic factors. Continuous glucose monitoring will be utilized to assess PGR, allowing for a comprehensive understanding of how different factors influence blood sugar control after meals.
Why it matters
Potential benefit: If successful, this study could lead to improved dietary recommendations and management strategies for individuals with type 1 diabetes.
How similar studies have gone: While studies have explored dietary impacts on glucose response, this specific investigation into gut microbiota's role in type 1 diabetes is relatively novel.
