In April 2025, Blue Cross Blue Shield of Massachusetts (BCBSMA), the states largest insurer, announced that it would end coverage of GLP-1 medications for obesity treatment beginning in January 2026, a move that will significantly restrict access for Boston residents who depend on these treatments
Commonly prescribed GLP-1 medications include: Semaglutide (Wegovy, Ozempic) , widely used for both weight loss and metabolic health due to its strong appetite-suppressing effect Liraglutide (Saxenda) , an earlier GLP-1 option that requires daily dosing rather than weekly injections Exenatide , a less commonly used medication today that helped establish early GLP-1 therapy All of these medications act on a single hormone pathway by activating the GLP-1 receptor

If appetite and food noise decrease within the first two weeks on tirzepatide, even at the starting 2.5mg dose, that is a strong positive signal
