Obesity is a chronic disease, and we need to treat it like one, says Sara Velayati, MD, an obesity medicine specialist at the Fleischer Institute Medical Weight Management Center at Montefiore Einstein in the Bronx, New York
Retatrutide (a triple-agonist peptide targeting GLP-1, GIP, and glucagon receptors) is a 39-amino-acid synthetic peptide currently in Phase 3 clinical research under the development designation LY3437943
Iron and calcium supplements must be separated from levothyroxine by at least 4 hours because they directly interfere with absorption, and this timing becomes even more important when gastric motility is already altered by tirzepatide
Combining the two drugs targeting different pathophysiologic mechanisms of T2DM has been expected to have a synergistic effect [1]
