Association between breath methane concentration and visceral fat area: a population-based cross-sectional study.
Ozato N, Saito S, Yamaguchi T, Katashima M, Tokuda I, Sawada K, Katsuragi Y, Kakuta M, Imoto S, Ihara K, Nakaji S. Ozato N, et al. J Breath Res. 2020 Feb 25;14(2):026008. doi: 10.1088/1752-7163/ab61c6. J Breath Res. 2020. PMID: 31835267
However, these studies define obesity using BMI, not VFA. In this population-based cross-sectional study, we investigated the relationship between breath gases (methane and hydrogen) and both VFA and BMI. ...The Methanogen + group was further divided i …

Influence of Body Composition and Specific Anthropometric Parameters on SIBO Type.
Wielgosz-Grochowska JP, Domanski N, Drywień ME. Wielgosz-Grochowska JP, et al. Nutrients. 2023 Sep 18;15(18):4035. doi: 10.3390/nu15184035. Nutrients. 2023. PMID: 37764818 Free PMC article.
Recent observations have shown that Small Intestinal Bacterial Overgrowth (SIBO)affects the host through various mechanisms. While both weight loss and obesity have been reported in the SIBO population due to alterations in the gut microbiome, very little is known a …

Intestinal methane production in obese individuals is associated with a higher body mass index.
Basseri RJ, Basseri B, Pimentel M, Chong K, Youdim A, Low K, Hwang L, Soffer E, Chang C, Mathur R. Basseri RJ, et al. Gastroenterol Hepatol (N Y). 2012 Jan;8(1):22-8. Gastroenterol Hepatol (N Y). 2012. PMID: 22347829 Free PMC article.
BACKGROUND: Obesity is an epidemic that affects 1 in 3 individuals in the United States, and recent evidence suggests that enteric microbiota may play a significant role in the development of obesity. ...BMI was significantly higher in methane-p …

Intestinal methane production is associated with decreased weight loss following bariatric surgery.
Mathur R, Mundi MS, Chua KS, Lorentz PA, Barlow GM, Lin E, Burch M, Youdim A, Pimentel M. Mathur R, et al. Obes Res Clin Pract. 2016 Nov-Dec;10(6):728-733. doi: 10.1016/j.orcp.2016.06.006. Epub 2016 Jul 2. Obes Res Clin Pract. 2016. PMID: 27380731
To determine whether methane and hydrogen on breath test affects weight loss after bariatric surgery, 156 subjects (pre-surgery BMI 33) were recruited 4 months after surgery. Pre- and post-surgery weights and BMIs were recorded. Post-surgery methane and hyd …
