Acid reflux/GERD worsening on GLP-1 — November 2025

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.

No disagreement with Dr.NutriCornell. One condition attached. 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.

Nausea arrived on day two of each dose step, lasted about four days, and disappeared entirely by the second week — until the step where it did not.

This matches mine closely enough to be worth saying so. 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.

From the other side of the consultation, briefly. If two explanations both fit, the useful question is which one predicts something the other does not. That is answerable; arguing about which sounds more plausible is not.
