how do glp 1 medications work GLP-1 Therapy Part 1: Setting Realistic Weight Loss Expectations – Sarah Hormachea How Long Does It Take

GLP-1 receptor agonist 7 generates cAMP under the mediation of GLP-1R with an EC of 0.2 nM

Insulin and insulin-like growth factors I and II (IGF-I and IGF-II) are critical for neuronal and glial growth, metabolic regulation, survival, gene expression, protein synthesis, neurotransmitter network modulation, and synaptic function.115 Cerebral insulin resistance may arise from the downregulation of insulin transport across the blood-brain barrier secondary to chronic peripheral hyperinsulinemia and systemic insulin resistance116 as well as from the loss of neuronal membrane insulin receptors induced by soluble amyloid-beta (A) oligomers.117 Impaired insulin signaling in the brain leads to increased activity of glycogen synthase kinase 3 beta, an enzyme implicated in enhanced A production and tau protein hyperphosphorylation.118 Furthermore, cerebral hyperinsulinemia is associated with diminished clearance of A peptides due to the competitive inhibition of insulin-degrading enzyme, a metalloprotease responsible for degrading both insulin and A, which preferentially binds insulin over A under hyperinsulinemic conditions.119 The neuroprotective properties of GLP-1RAs have been substantiated in vivo, supported by their ability to traverse the blood-brain barrier and the presence of GLP-1 receptors within the brain

Semaglutide slows stomach emptying, which can paradoxically reduce urgency in some post-cholecystectomy patients by allowing more time for fluid reabsorption

More research is needed to understand the potential long-term effects of these medications on hair health and determine if specific risk factors predispose individuals to hair loss while undergoing treatment

At the tissue level, GLP-1 agonists diminish ectopic fat accumulation in the liver and muscle, enhancing insulin sensitivity
