Functional dyspepsia and gastroparesis are common stomach disorders with symptoms like early satiety, nausea, and abdominal pain, and are often evaluated with gastric emptying tests, although the correlation with symptoms is weak. Prokinetic agents (e.g., metoclopramide, erythromycin) and symptom modulators (e.g., nortriptyline, mirtazapine) are commonly used, but selecting the right medication can be difficult, as it's often based on symptoms rather than the underlying gastric issues. Body Surface Gastric Mapping (BSGM) using the Gastric Alimetry device is a novel, non-invasive tool to assess gastric myoelectrical activity and symptoms. This study aims to perform two BSGM recordings-one before and one after medical therapy-to understand how medications affect gastric function and identify baseline BSGM factors that could predict responses to treatment, potentially guiding tailored therapies based on individual gastric dysfunction.

Change in overall postprandial BSGM Gastric Alimetry Rhythm Index (minimum: 0; maximum: 1) on treatment compared to baseline (with a lower score meaning worse outcome).
Time frame: 8 weeks
Change in overall BSGM BMI-Adjusted Amplitude on treatment compared to baseline (normal range: 22-70 μV).
Time frame: 8 weeks
Change in overall BSGM Principal Gastric Frequency (minimum: 0; maximum: 5) on treatment compared to baseline (normal range: 2.65-3.35 cpm).
Time frame: 8 weeks
Change in overall BSGM Fed:Fasted Amplitude Ratio on treatment compared to baseline (normal range: >1.08).
Time frame: 8 weeks
