Why dual-pathway targeting is more effective Single pathway limitations: GLP-1 alone eventually plateaus Body compensates over time Weight loss slows after 6-12 months Some people don't respond optimally Dual pathway advantages: Harder for body to compensate Multiple redundant systems targeted Sustained weight loss longer Better for non-responders to single therapy Mechanistic synergy: Amylin + GLP-1 naturally work together Both released after meals normally Physiologic combination Not forcing unnatural state Clinical implications: Patients who plateau on semaglutide benefit from adding cagrilintide Initial combination produces maximum results May prevent or delay weight regain Better long-term outcomes Cagrilintide and semaglutide dosing protocols Proper dosing ensures maximum efficacy with manageable side effects
