Heartburn management on constipation: Gaviscon before bed has been my savior. The delayed gastric emptying means stomach acid just sits there.
Don't ignore persistent heartburn — chronic acid exposure can damage your esophagus. If OTC remedies aren't cutting it after 2 weeks, see your doctor for something stronger. You shouldn't suffer through this.

Thank you for spelling out the reasoning rather than just the conclusion.

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.
