Summary

The goal of this cross-sectional observational study is to examine potential relationships between the blood and gut microbiota of patients with obesity before and after weight loss surgery (WLS) and evaluate potential ethnic differences in the blood and gut microbiotas before and after the WLS. The main aims / objectives of this sub-study are: * Aim 1. Compare the relationship between the blood and the gut microbiomes among a sample of (1) pre-WLS and (2) 6-month post-WLS participants. Hypothesis: Blood bacterial composition will resemble that of the gut microbiome among pre-WLS participants. Because the effect of WLS on the blood microbiome is not known, our post-WLS results will be mostly exploratory. * Aim 2. Determine racial differences in the blood microbiome of the pre- and post-WLS groups. Hypothesis2: Ethnic differences will be detected in both the pre- and post-WLS groups.

Detailed description

A subgroup of participants from the main study will be invited to participate in a cross-sectional sub study evaluating the relationship between blood and gut microbiotas. A total of 100 participants will be recruited, 50 participants will be recruited from the "non-completers" and the other 50 participants will be recruited from the "6 months post-WLS" follow-up group of our main project.
