Summary

This study uses MRI scans to measure blood flow in the gut after drinking sugar water in people with postprandial hypotension (a drop in blood pressure after meals) and healthy volunteers. Researchers will test whether blocking a hormone called GIP changes blood flow patterns. The goal is to better understand what causes this condition, not to test a new treatment.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: GIP(3-30)NH2 infusion, hangrip exercises, saline infusion
What this could lead to: If successful, this could clarify how gut blood flow changes after eating in people with postprandial hypotension, potentially pointing toward new ways to manage the condition.
What could go wrong: This is a small, early-stage observational study with only 30 participants. It is not testing a treatment, so it may not lead directly to any therapy.
