สรุป	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 GERD Health-Related Quality of Life Scale (GERD-HRQL) is a concise, validated patient-reported outcome measure for assessing the symptomatic and functional impact of gastroesophageal reflux disease (GERD). Developed by Velanovich and colleagues in 1996, the 9-item GERD-HRQL measures heartburn frequency and severity, regurgitation, and impact on sleep and medication use. The scale is highly responsive to proton pump inhibitor (PPI) therapy and is widely used in GERD trials and clinical practice.
