Stomach trouble? scientists check body fat and muscle in new study
NCT ID NCT07196735
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether women with functional dyspepsia (a condition causing stomach pain and discomfort without a clear cause) have different body composition than healthy women. Researchers will use a simple, non-invasive test called bio-electrical impedance to measure fat mass, fat-free mass, and phase angle. The goal is to better understand the condition, not to test a treatment.
