GI Upset at Tirzepatide 15mg — How to Cope
Nausea at the 15mg dose is one of the most reported side effects. At the 15mg dose level, GI adjustment takes a few weeks to accommodate this dose of GLP-1 receptor activation.
Why 15mg Causes Nausea
Tirzepatide at 15mg engages GLP-1 receptors throughout the GI tract and CNS that produces nausea through several mechanisms: direct activation of the area postrema, slowed gastric emptying, and changed gut-brain axis signaling.
Symptoms at 15mg hits hardest in the first week or two and resolves within a month.
