Summary
What are gastrointestinal symptoms?
Gastrointestinal symptoms broadly describe patient-reported gastrointestinal-related subjective sensations — bloating, nausea, diarrhea, etc. — that have been pooled into a single metric.
Such metrics, which include the Gastrointestinal Symptom Rating Scale (GSRS) [1][2][3][4] or Visual Analog Scale (VAS) [5], are commonly used in research on conditions like irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and gastroesophageal reflux disease (GERD). However, they are also used in dietary research and studies on sports nutrition.

In this 6-week randomized controlled trial in 219 people with bloating and/or indigestion, taking a synbiotic that contained pomegranate extract and probiotics reduced gastrointestinal symptoms.
