I plan to continue indefinitely unless medullary thyroid cancer appears though newer data shows no extra risk from these meds unless you already have a predisposition. Dropping close to one hundred pounds has brought my labs to ideal levels and removed the need for six blood pressure prescriptions I took for twenty five years plus three statins. The improvements in hypertension cholesterol fasting blood sugar and A1C are tied to the weight loss but the medication made that possible. At current supply levels the monthly amount costs very little and I doubt anything else in health care matches that value.
From what I gather these meds become a permanent commitment once you start them. Research shows that after using sema or tirzep and likely reta later on you drop a lot of weight and feel better but when you quit the pounds tend to creep back over about a year and there is no sign your system will suddenly stabilize at the new lower level. A few rare cases online claim they kept it off for years after stopping but that seems uncommon. About a third of the people at my workplace are using one of these glp1 options and those close to their target often talk about finishing the course and getting off soon. Insurance also cuts coverage once weight is no longer in the obese range treating it as resolved.
