Briefly, mice were individually housed in standard laboratory cages

Other research highlights: 30% of GLP-1 users tested positive for SIBO or IMO even after accounting for diabetes (5) GLP-1 medicines caused microbiome changes and altered metabolism in mice (6) GLP-1 medicines tested in humans only had noticeable microbiome changes by 48 weeks (7) Despite not necessarily having slower gut motility, one study found that 88.9% of obese patients had SIBO (8) A meta analysis of people with IBS symptoms, found that up to 78% of people had SIBO, many of whom were undiagnosed (9) Overall, Sun and colleagues (1) could not prove a mechanistic link between GLP-1 medications and SIBO, however they did find that SIBO was twice as likely in GLP-1 users
Neuroprotection: GLP-1s cross the blood-brain barrier and act on microglia, supporting brain and mood health
By covalent (albiglutide, dulaglutide) or no-covalent (semaglutide) coupling to larger molecules with slow clearance, analogs with even more prolonged activity have been produced so that there are now several once-weekly agonists on the market
