GLP-1 and menstrual irregularity — looking for input

This one has a reasonably settled answer, so here it is. Holding genuinely reduces total burden rather than redistributing it, because the gastric-emptying component adapts. Receptor-level tachyphylaxis to the delayed-emptying effect develops over weeks while the central appetite effect persists, so the same dose is materially more comfortable at week six than at week two. A slower ladder therefore reaches the same dose with less cumulative nausea, not the same nausea spread thinner.

Dr.GutHealth has the substance of this right. The condition it depends on is worth stating. The meal advice is right and incomplete without the hydration point. People stop drinking because drinking makes them feel full, then attribute dehydration symptoms to the drug.

The nausea I get is not really nausea, it is an aversion.

Can confirm the pattern claudia_zurich describes. The line between titrate-through and stop is not severity, it is trajectory and what else is present. Nausea that peaks and improves within a week is the expected pattern. Nausea that is escalating, or that comes with severe upper-abdominal pain radiating to the back, or that prevents fluids for more than a day, is a different conversation and belongs with a clinician the same day.

Happy to go further on any of that.

From the other side of the consultation, briefly. It is worth asking what the claim would look like if it were false. If nothing would look different, it is not a claim about the world and no amount of discussion will settle it.
