Why might a GLP-1 change how levothyroxine feels?

Approved GLP-1 drugs slow gastric emptying (how fast food leaves the stomach), which can change how some pills are absorbed. Levothyroxine is one of the pills people ask about. Feeling different after starting a GLP-1 is a reason to talk to the clinician or pharmacist who already manages your thyroid prescription. It is not a reason to invent a new timing ritual from a forum. This site does not publish a levothyroxine schedule.
