Can confirm. Same sequence, different timescale.

That reframing is the part I needed. Sending this to two other people who asked me the same thing last week.

Adding the clinical framing, because it changes how the question reads.

Gastric emptying studies and constipation: semaglutide delays gastric emptying by ~40% at steady state, as measured by acetaminophen absorption testing and scintigraphy[1].

Clinically relevant implications:

• Explains early satiety and nausea
• Affects absorption of co-administered oral medications
• Creates aspiration risk for procedures under anesthesia
• Contributes to constipation via slowed GI transit

Importantly, the gastric emptying delay attenuates with continued use (tachyphylaxis), which correlates with the transient nature of GI side effects.

This is my experience too, for whatever a second data point is worth. Nothing to add that would improve it.
