Gut hormone may explain Post-Meal dizziness in POTS
NCT ID NCT05375968
First seen Oct 31, 2025 · Last updated May 01, 2026 · Updated 27 times
Summary
This study looks at why people with POTS feel worse after eating sugary or high-carb meals. Researchers think a gut hormone called GIP may cause extra blood to pool in the belly, leading to dizziness and rapid heart rate when standing. About 50 participants (25 with POTS and 25 healthy volunteers) will drink a sugary drink and have their blood flow measured. Some will also receive an experimental drug to block GIP, to see if it reduces symptoms.
