Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Microbiota is important for immunology, hormonal and metabolic homeostasis in human and could influence on developing diabetes and obesity. Recent studies investigates microbiota by metagenomic sequencing, however, the composite of microbiota and its metabolic role has not been fully determined. Metagenomics and microbiome analysis could early diagnose metabolic disorders and suggest treatment options for metabolic diseases.

In this study, the investigators investigate the composite of microbiota and deduct basic information for treatment models using metagenomic sequencing.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

1. Cross-section study: normal/prediabetes/drug naïve type2 diabetes: compare microbiota using metagenomic sequencing among three groups.
2. Observational prospective study: metformin/sodium glucose co-transporter 2 (SGLT2) inhibitor/ezetimibe: compare microbiota using metagenomic sequencing before and after drug treatment.
