Understanding thee Gasterintentinal Side Effects of GLP- 1 Receptor Agonists

Glucagon- like peptide-1 (GLP- 1) receptor agonists have e concepte a constantstone in the management of type 2 diabetes and, more recently, in obesity treatent. Medications such as semaglutide (Ozempic, Wegovy), liraglutide (Victoza, Saxenda), dulaglutide (Trulicity), and exenatide (Byetta) work by micking thee action of natural inkrees.

Te Mechanismus Behind Gasterinothinal Side Effects

Delayed Gastric Emptying

Te primary effectr of GI side effects with GLP-1 receptor agonists is th drug-induced delay in gastric emptying. GLP-1 receptory are expressed the gastrointent thee gastintentinal trakt, and when activated, they slow down thate rate at which ich te stomach empties it contents into thee small contentiine.

Beyond direct gastric effects, GLP- 1 receptor agonists influence the brainth-gut axis.
