خلاصه	The Gastroparesis Cardinal Symptom Index (GCSI) is a validated, patient-reported outcome measure specifically designed to assess symptom severity in gastroparesis. Developed by Revicki and colleagues in 2003, the GCSI captures the three cardinal symptom clusters of gastroparesis: nausea and vomiting, postprandial fullness, and early satiety, plus bloating and stomach distension. The 9-item questionnaire is responsive to treatment changes and is increasingly used in clinical trials and practice to monitor gastroparesis progression and therapy response.	The Rome IV criteria are the internationally accepted diagnostic standard for irritable bowel syndrome (IBS), published in 2016 by the Rome Foundation. These criteria define IBS as recurrent abdominal pain (≥1 day per week for ≥3 months) associated with altered bowel habits, without structural or biochemical abnormalities. IBS is subtyped into four patterns—IBS-constipation predominant (IBS-C), IBS-diarrhea predominant (IBS-D), IBS-mixed (IBS-M), and IBS-unclassified (IBS-U)—based on stool consistency patterns.
