Obesity
Conditions
Brief summary
For obese individuals, semaglutide treatment was adopted. By using multi-omics techniques such as fecal metagenomic sequencing and based on in vitro strain screening platforms, the effects and specific mechanisms of semaglutide on the intestinal flora of obese patients were clarified.
