Functional dyspepsia (FD) is a common disorder that causes stomach discomfort, such as fullness or pain after eating, without any visible structural disease. Acupuncture is often used to manage these symptoms. This study aims to evaluate the safety and effectiveness of electroacupuncture-a form of acupuncture that uses gentle electrical stimulation-for treating functional dyspepsia. Specifically, the trial will compare the benefits of applying electroacupuncture to points on the abdomen (local points) versus points on the arms and legs (distal points), alongside a control group receiving a sham (inactive) treatment. The goal is to determine the most effective acupuncture strategy for improving patients' digestive symptoms and overall quality of life.

Functional dyspepsia symptoms caused by severe or malignant diseases (e.g., liver cirrhosis, heart failure, or gastrointestinal tumors).
