Overview

Brief Summary Template for the Study:

The goal of this clinical trial is to evaluate whether electroacupuncture can treat functional dyspepsia (FD) in adult participants aged 18 to 65 years, including both males and females, who have been diagnosed with functional dyspepsia based on the Rome IV criteria. The main questions it aims to answer are:

• Does 5 Hz electroacupuncture improve symptoms in functional dyspepsia patients?
• Does 100 Hz electroacupuncture improve symptoms in functional dyspepsia patients?
• Are there differences in the efficacy between 5 Hz and 100 Hz electroacupuncture in treating functional dyspepsia and its subtypes (PDS and EPS)?

Researchers will compare the effects of 5 Hz electroacupuncture, 100 Hz electroacupuncture, and sham electroacupuncture to determine which approach provides more significant symptom relief and whether different frequencies have varying impacts on FD subtypes.

Participants will:

• Receive electroacupuncture treatment at specific acupoints (such as Liangmen, Tianshu, Zusanli, and Xiajuxu) for 30-minute sessions, 3 times a week for 4 weeks.
• Be randomly assigned to one of the following groups: 5 Hz electroacupuncture, 100 Hz electroacupuncture, or sham electroacupuncture (control).
• Have their functional dyspepsia symptoms, quality of life, and any adverse effects monitored and evaluated throughout the study.
