Some are taken twice daily, some extended-release (ER) weekly, and others once daily
It has been proposed that GIP regulates inflammation and leukocyte adhesion through endothelin 1 while promoting vasodilation via nitric oxide secretion [109]
Yet by 2000, a strategy had emerged to prolong the effect of GLP-1 signaling: generate DPP-4 resistant peptides that bind and activate (i.e., agonize) GLP-1R
Specifically, GLP-1RAs appear to exert a direct protective effect on the liver by enhancing hepatic insulin sensitivity by activating the PI3K/Akt signaling pathway, which promotes glucose uptake while reducing gluconeogenesis [46]
A 2025 Springer review on the topic confirmed that women with PCOS face unique metabolic challenges, including heightened insulin resistance, compounded by obesity that require targeted, not generic, interventions
Chief among those concerns are side effects, with 51% of respondents citing current side effects such as nausea, vomiting, headaches, and more as a top concern when it comes to GLP-1 medications, while 40% said they are worried about potential long-term side effects that may develop with use
