A Non-Interventional Pilot Study to Explore the Role of Gut Flora in Obesity

This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records regarding obesity.

Study Overview

• Status: Recruiting
• Conditions: Obesity; Obesity, Morbid; Overweight and Obesity; Overweight or Obesity; Obesity, Abdominal; Obesity Hypoventilation Syndrome; Obesity; Endocrine; Obesity; Familial; Obesity, Visceral

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Correlation of Microbiome to Obesity via Relative Abundance Found in Microbiome Sequencing	Relative abundance of bacterial classes within taxonomic phyla and, more broadly, within their domain will be analyzed by sequencing the gut microbiome. These data will then be categorized among obesity types	1 year

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Validation of Sequencing Methods	To validate the methods used to sequence samples	1 year
