FD is highly prevalent and burdensome, with a complex and multifactorial pathophysiology. A wide range of gastrointestinal functional tests has been developed, from established barostat and scintigraphy to emerging noninvasive methods such as cine magnetic resonance imaging, endoscopy-based functional testing, wireless motility capsule, and body surface gastric mapping. These novel approaches can capture both motor and sensory abnormalities, offering new opportunities for personalized management of FD. Standardization, validation, and wider clinical implementation of these functional assessments are needed to translate research advances into routine practice.
