NCT06657287

Brief Summary

The goal of this observational study is to learn about the relationship between postprandial hypotension and insulin levels in adults. The main question it aims to answer is: Is the incidence of postprandial hypotension high in patients who undergo mixed meal test? Is insulin level higher in individuals with postprandial hypotension compared to those without during a mixed meal test? Patients with postprandial symptoms were scheduled for a mixed meal test, during which plasma glucose, insulin, C-peptide, blood pressure, and heart rate were measured at specific time points.
