Zapping nerves to tame stubborn high blood pressure and diabetes?
NCT ID NCT06880562
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a procedure that uses radiofrequency energy to disable certain nerves near the kidneys and abdomen. The goal is to see if this can safely lower blood pressure and improve blood sugar control in 20 adults with resistant hypertension and type 2 diabetes who have not responded well to medications. Participants will be followed for three months after the procedure.
