So far no studies address this situation at all. Going straight to reta makes sense because if GLP-1 alone does little, adding GIP and glucagon might change things, or trying an amylin drug like cagri could work through a different route. Variants in the GLP-1 receptor or its signaling pathways likely explain why some people get almost no weight loss. Odds of also responding poorly to tirz or reta are probably higher than normal, though still worth testing for a couple of months. I stayed on low-dose ozempic for a year with no scale movement, just constant tiredness and mild nausea, though appetite was somewhat lower.
My spouse tried semaglutide for six months, reaching a top dose of 1 mg. There was zero effect of any kind, no appetite control and no pounds lost, only tiredness. Would switching to tirzepatide or retatrutide give a better shot at results? Anyone seen cases like this with people who show no response?
