Obesity-Brain link probed: sugar, gut bugs, and iron under the microscope
NCT ID NCT03889132
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study looked at 128 adults with obesity to understand how blood sugar levels, gut bacteria, and brain iron deposits are connected to thinking skills. Some participants followed a diet or had bariatric surgery, but the goal was to observe changes over one year, not to test a new treatment. The findings may help explain why obesity affects brain health.
