Different faces of gastroparesis.

Area of Science:

• Gastroenterology
• Clinical Medicine
• Patient-Reported Outcomes

Background:

• Gastroparesis is a chronic disorder characterized by delayed gastric emptying, leading to debilitating symptoms.
• Current management often focuses on gastric emptying, but the contribution of psychological factors to symptom severity is not fully understood.

Purpose of the Study:

• To investigate the hypothesis that pain and affect, rather than impaired gastric emptying, are the primary determinants of symptom severity in gastroparesis patients.

Main Methods:

• Prospective enrollment of adult gastroparesis patients at a single center.
• Assessment using validated questionnaires: Gastroparesis Cardinal Symptom Index (GCSI), Hospital Anxiety and Depression Scale (HADS), Short Form 12 (SF-12).
• Inclusion of pain severity ratings and open-ended questions to capture patient experiences.

Main Results:

• In univariate analyses, the SF-12 physical subscore and HADS scores correlated significantly with GCSI scores, unlike gastric emptying delay.
• Multivariate analysis indicated that a combination of vomiting, bloating, and depression best predicted the overall impact on quality of life.
• Commonly reported dominant symptoms included nausea/vomiting, pain, and bloating.

Conclusions:

• The study confirms the significant role of pain and affect (anxiety and depression) in gastroparesis symptom severity.
• Findings underscore the need for novel therapeutic approaches that address psychological well-being to enhance patient quality of life.
